A New Wrinkle on H. G. Rickover – A Real Life Saver 4

I was doing a little research this morning about the main subject of a book I am writing and I ran across a little gem that while unrelated was certainly an eye catcher. It had to do with a young Lieutenant named Hyman G. Rickover. Okay, to be fair, he wasn’t all that old when he was recognized in the June 13, 1931 Bureau of Navigation Bulletin Number 159. When Mr. Rickover was already 29 years old, he entered the submarine service. When this mention occurred, he was 31 years old.

The exact wording of the recognition was this:

“The Secretary of the Navy recently addressed letters of commendation to the officers listed below:

Lieutenant Hyman G. Rickover, U.S.N., U.S.S. 48

For rescuing Augustin Pasis, MAtt. 1c, U.S.N. from drowning at the Submarine Base, Coco Solo, Canal Zone”

Petty Officer Pasis was a First Class Mess Attendant that was returning from shore leave when he fell over the side of the boat according to the June 3rd San Antonio Express Newspaper.

To be honest, I only met Admiral Rickover one time.

I was on my third submarine and it was the spring of 1981 when the USS San Francisco was on sea trials. Looking at the frail old man, I was awestruck with how much power he still wielded even in his later years. None of us knew that within a year he would be forced out of the Navy he had spent a life serving. But thinking about his size, it’s hard for me to imagine that even at a younger age, he might have the strength to rescue a drowning sailor. In between other projects today, I did a little research about his time in submarines and especially on the S-48.

I have researched the S boats for years and I know some of the history about the four boats that made up the “4th Group” of S boats. None of them faired very well and the S-48 was no exception.

From the records:

“Rickover preferred life on smaller ships, and he also knew that young officers in the submarine service were advancing quickly, so he went to Washington and volunteered for submarine duty. His application was turned down due to his age, at that time 29 years. Fortunately for Rickover, he ran into his former commanding officer from Nevada while leaving the building, who interceded successfully on his behalf. From 1929 to 1933, Rickover qualified for submarine duty aboard the submarines S-9 and S-48.

On 1 June 1929, S-48 had been reassigned to SubDiv 4, with which she operated through the end of 1929. Then assigned to SubDiv 3, later SubDiv 5, and then Squadron 3, she continued her operations off the New England coast, with an interruption for winter maneuvers to the south. During this time, Lieutenant Hyman G. Rickover was assigned to her. He later credited S-48′s “faulty, sooty, dangerous and repellent engineering” with inspiring his obsession for high engineering standards. She was transferred to the Panama Canal Zone in 1931. On 1 March, she arrived at Coco Solo, whence she operated for four years.

SS-159 S-48

Four “4th Group” S-boats were constructed. The 4th Group S-boats were the largest of the fifty-one S-boats contracted to be built for the United States Navy. These S-boats had six water-tight compartments to enhance internal integrity. S-48 thru S-51 were authorized in FY1920 and laid down 1919-20 at Lake Torpedo Company, Bridgeport CT. They were modified “S” class boats which added an aft torpedo tube which resulted in 27 tons additional displacement. All four commissioned in 1922.

The S-48 Class submarines were 240′ in length overall; had an extreme beam of 21’10”; had a normal surface displacement of 903 tons, and, when on the surface in that condition, had a mean draft of 13’6″. The submarines displaced 1,230 tons when submerged. The designed compliment was 4 officers and 34 enlisted men. The S-boat was equipped with two periscopes. She had a double hull in the center portion of the boat; a single hull at each end of the ship. This S-boat could completely submerge in one minute to periscope depth. Maximum operating (test) depth was 200′.

The submarine was armed with five 21-inch torpedo tubes (four in the bow and one in the stern). Fourteen torpedoes were carried. One 4-inch/50-caliber gun was mounted on the main deck forward of the conning tower fairwater.

Stowage was provided for 44,350 gallons of diesel oil by utilizing some of the ballast tanks as fuel oil tanks. This gave the boat a maximum operating radius of 8,000 miles at ten knots when transiting on the surface. The normal fuel oil load was 23,411 gallons. Two 6-M-85 six-cylinder 900 brake horsepower (at 410 rotations per minute) diesel engines, that had a total output of 1,800 horsepower, that were made by the Busch-Sulzer Brothers Diesel Engine Company at Saint Louis, Missouri, could drive the boat at 14.4 knots when operating on the surface.

Submerged propulsion electrical power was provided by the 120 cell main storage battery which was manufactured by the Gould Storage Battery Company at Trenton (“Trenton makes, the world takes”), New Jersey, which powered two 750 B.H.P. electric motors, with a total output of 1,500 designed brake horsepower, that were manufactured by the Ridgeway Dynamo and Electric Company at Ridgeway, Pennsylvania which turned propeller shafts which turned propellers which drove the submarine at 11 knots, for a short period of time, when submerged.

Two of the four boats would suffer battery explosions and decommissioned in 1927 and a third would be lost when rammed by a merchant ship. The lead ship of the class grounded off New Hampshire during a storm and her crew was evacuated. The resulting repairs and modernization would keep her out of commission for over three years.

In February 1924, S-50 (SS-161) suffered a battery explosion which resulted in exhaustive engineering testing and her early decommissioned in August 1927. On 29 January 1925, S-48 (SS-159) grounded off the New Hampshire coast and her crew was evacuated during a storm. She would be salvaged and modernized, returning to commission in December 1928. S-51 (SS-162) was rammed and sunk by the merchant SS City of Rome off Block Island, RI on 25 September 1925. She was raised in 1926 and sold for scrap in 1930. On 20 April 1926 S-49 (SS-160) suffered a battery explosion and was decommissioned in August 1927.

A Hard Luck Sub

S-48’s hard luck started 10 months after launching, when the yet-to-be-commissioned sub conducted her first test dive in New York Sound off of Penfield Reef on December 7, 1921.

According to press reports, the 240-foot boat “was hardly under water before the shouted reports came from the aft part of the vessel: ‘Engine room flooding! Motor room flooding!’” Emergency procedures kicked in. The men in the aft compartments stumbled forward and the forward compartment doors were shut. “A moment later the stern softly bumped on the bottom. The electric lights went out.” Flashlights in hand, the sub’s Commander, Lt. Francis Smith, ordered the ballast tanks blown, but “the weight of the water in the stern compartments was too much…her nose tilting up a little but that was all.” Two hundred pounds of pig lead ballast bars were jettisoned through an air lock and four dummy torpedoes were shot out, on which the crew had painted “HELP” and “SUBMARINE SUNK HERE” along with numerous milk bottles “in which messages were enclosed giving notice of the plight of the vessel.”

Slowly the bow began to rise like an inverse pendulum, but the stern stuck to the bottom. The upward tilt shifted the stern water. “Port batteries flooding!” yelled a crewman. The New York Evening News described the dramatic moment: “Breathing stopped. A flooded battery means chlorine [gas].” Cmdr. Smith and three crewmen immediately began bailing “to get seawater below the level of the [battery containers]…their hands were burned and every moment or two a whiff [of chlorine gas] drifted across their faces,” making them cough and choke. No sooner had they gotten the water off the port side batteries that the starboard batteries started flooding. At the same time, the boat’s bow continued to tilt upward as more material weight was jettisoned. At 30 degrees, the ships executive officers were certain the bow was above the surface “more than sixty feet from the bottom.”

One member of the crew, while being pushed from behind, wriggled and worked his way out of the sub through a torpedo tube, which was about four feet higher than the ocean surface. A rope was passed up the tube, and the remaining crew of 50 were pulled out one by one. Hot coffee and blankets were also hauled up as the men huddled in the freezing weather. One Sailor’s wet underclothing “was frozen into a solid casing about his shoulders and legs.”

Some of the men went back down into the sub through the torpedo tube and “hauled out mattresses [which]…one by one were burned at the tip of the upstanding bow…the men sitting around their flaming signal…[warming themselves from] a stiff wind…[and] rough waters.” They were finally rescued at 10:30 PM by a passing tug. The ordeal had lasted 14 hours, 10 of which were spent exposed to the frigid elements. Three men were briefly hospitalized for minor chlorine gas inhalation. Most of the men were employees of the Lake Torpedo Boat Co. of Bridgeport, Conn.

Initial reports by the Associated Press claimed that the sub had been hit by a tug boat, but it was later learned that somebody left open one of the airtight “manholes.” Divers were able to secure the hatch and refloat the vessel.

By the following August (1922), the S-48 began its second series of tests on Long Island Sound, diving to a depth of 100 feet and firing torpedoes and “other such trials.” She was accepted and commissioned by the U.S. Navy in October of 1922. Over the next three years, she was in and out of New London, Conn. for repairs. She ran aground twice in 1926 during a violent storm once taking on water, which again caused chlorine gas to form. She was then returned to New London for the fifth time. Due to a lack of repair funds, the submarine was decommissioned. Funds became available in 1927 and repairs commenced, which included a hull extension of 25½ feet. In December 1928, she was recommissioned. Within seven months, she was back at New London undergoing repairs before resuming operations in June 1929.

It was a year later that Rickover joined the crew.

By then, S-48 was the only remaining S-class submarine from the four-boat Group IV consisting of S-48 to S-51. S-49 and S-50 experienced battery explosions and S-51 sank due to a collision with a passenger ship. By the time Rickover reported aboard the S-48, her two surviving sister ships, themselves mechanical and electrical nightmares, had been decommissioned.

In his biography, “Rickover: The Struggle for Excellence,” Francis Duncan reports on a myriad of mechanical and electrical problems confronted by the young engineering officer on his first cruise aboard the S-48. He relates that the pneumatic control valves used to submerge the ship never “synchronized [properly and thus when diving] she [always] lurched to one side or the other…to as much as twelve degrees.” Rickover wrote about his first cruise in July of 1930. Less than an hour into the cruise, a malfunctioning electrical controller forced the sub to stop. Once fixed, the gyro compass repeater then “went haywire…[making it] impossible to steer a correct course,” he reported. About an hour later, an exhaust valve stem cracked, forcing another stop. It was repaired and “then three…cylinder jackets of the port engine developed leaks… [Rickover, fearing the Captain] would become disgusted [with his performance] took the chance and ran with the leaky cylinder jackets…” If that wasn’t enough, several hours later “the electrician reported…something wrong with one of the main motors.” Crawling into the bilges to check out a “jangling in the bow,” he discovered the anchor chain was loose, “the control panel for the anchor windlass had become grounded.”

Two months later, smoke belched from a ventilator fan; a main battery had caught fire. According to Thomas Rockwell in his book, “The Rickover Effect,” the skipper, fearing an explosion, “ordered all men on deck, prepared to jump overboard if the expected hydrogen explosion occurred.” Believing the problem was his responsibility, Rickover volunteered to re-enter the sub and fix the problem. Rickover wrote, “the smoke was coming from the battery compartment…when it was opened black smoke billowed forth… Wearing a gas mask and trailing a lifeline [Rickover ventured through the hatch].” Finding no fire, he rigged a ventilating system and lime was placed in the compartment to absorb carbon dioxide. A later examination revealed that the fire had started by sparking battery connections. Three hours later, a short circuit in the “charred battery connections” started yet another fire, which he unsuccessfully attempted to put out with a carbon tetrachloride fire extinguisher. In desperation, he successfully sprinkled lime on the flames. It worked. The cause of the second fire was old and deteriorating insulation. Rockwell also relates that Rickover was confronted with propulsion motors that “were a continual source of trouble.” Showing his hands-on approach to problem solving, “he redesigned and rebuilt them [after which] they caused no further trouble.”

13 June 1931 Bureau of Navigation Bulletin… Rickover commended for saving a petty officer form drowning

In July 1931, Rickover was promoted to Executive Officer.

In November, the S-48 had another mishap. She started a dive for a practice torpedo run and immediately “she took a twelve-degree list and a sharp downward angle. At seventy feet…she was out of control…blowing the tanks…brought her up… [A later] investigation showed a vent valve had failed to open.” In February of 1932, after several diving mishaps, a group of officers “nervous and tired, had drawn up a message…for all to sign, stating the ship was unsafe and could not complete her assignment.” According to Duncan, “Rickover argued them out of it…it would be bad for the reputations of all concerned and [told them] that he could work out a new diving procedure.” His diving protocol meant diving took longer, but it worked.

The 1932 Navy-Princeton gravity expedition to the West Indies

The first gravity measurements at sea had been made in 1926 from a submarine of the Royal Navy. The first U.S. gravity measurements at sea had been made from the submarine USS S-21 (SS-126), assisted by the Eagle Boats USS Eagle No. 35 and USS Eagle No. 58.

S-48 was assigned at the request of the Hydrographer of the Navy by the Secretary of the Navy to assist with the second U.S. expedition to obtain gravity measurements at sea using a gravimeter, or gravity meter, designed by Dr. Felix Vening Meinesz. Meinesz, joined by Dr. Harry Hammond Hess of Princeton University, and a U.S. Navy technician, participated in the expedition. The submarine was accompanied and assisted by the minesweeper USS Chewink (AM-39) in a route from Guantanamo Bay, Cuba to Key West, Florida and return to Guantanamo through the Bahamas and Turks and Caicos region from 5 February through 25 March 1932. The description of operations and results of the expedition were published by the U.S. Navy Hydrographic Office in The Navy-Princeton gravity expedition to the West Indies in 1932.

SS-159 S-48

Despite her frequent mechanical and electrical mishaps, sinking’s, and groundings, the Lake Torpedo Boat Co. built S-48 was finally deactivated in 1935 and berthed at League Island, N.Y. At the beginning of WWII, she was reactivated and used for training at New London. “Overhaul and repair periods [during the war] were frequent,” history records.

The hard luck S-48 was decommissioned in 1945 and scrapped the following year after 25 years of service, three of which inspired one of the Navy’s most respected and honored seamen.”

I do not know what happened to the man Rickover saved. He had a son that lived in Norfolk but the only other records I could find indicated that he followed a sailor’s life. Like Rickover, he was in his late twenties or early thirties so I can imagine that he would continue on serving the Navy through the next decade at least.

Like most people that rode nuc boats, we owed a lot to the man who guided the Navy’s nuclear power program. I have a new appreciation for him after reading about his exploits on the S 48 boat.

He probably had a second tour as CO as a LCDR in S-48 in 1934. In WW II he became the one and only CO of amphibious transport ship Thomas Stone (APA-29) from 18-MAY-1942 to 01-APR-1944.

 

 

 

 

 

Floating Drydocks: A Noteworthy Innovation That Changed the Course of Two Wars 7

Floating Drydocks had been around for a long time before World War 2. But the scope of naval warfare during World War 2 and the Cold War that would follow would test the Navy’s ability to maintain vessels in faraway locations. This is part on of the story of docks like USS Los Alamos (AFDB 7) which serviced the Polaris and Poseidon Missile submarines of the Cold War.

Looking back on the years since the LA was placed out of commission, its easy to forget that for over thirty years she served on the front lines of a different kind of conflict. But it was a need identified and filled many years before that which made her ability to fill this new role possible. This is the story of the Floating Drydocks of World War II.

 

Advanced Base Sectional Dock Number 3

“The fleet of floating drydocks built by the Bureau of Yards and Docks during World War II was a significant and at times dramatic factor in the Navy’s success in waging global war.

It had long been recognized that in the event of another world war the fleet would be required to operate in remote waters, and that ships were going to suffer hard usage and serious battle damage. It was obvious that many crippled ships would be lost, or at least would be out of action for months while returning to home ports for repairs, unless mobile floating drydocks could be provided that could trail the fleet wherever it went. It was the Bureau’s responsibility to meet these requirements.

Floating drydocks have been used for overhaul and repair of ships for many years, and many ingenious designs have been devised from time to time. One of the most interesting was the Adamson dock, patented in 1816, which may be considered the prototype of some of the new mobile docks. The Navy apparently built several wooden sectional docks at various navy yards about 1850, but little is known of their history.

About 1900, two new steel floating drydocks were built for the Navy. The first of these, of 18,000 tons lifting capacity, was built in 1899-1902 at Sparrow’s Point, Md., and towed to the Naval Station a Algiers, La., where it was kept in intermittent service for many years. In 1940, it was towed via the Panama Canal to Pearl Harbor to supplement the inadequate docking facilities there. Since the dock was wider than the Canal locks, it was necessary to disassemble it at Cristobal and to reassemble it at Balboa. Although both the dock and the ship in it were damaged during the Japanese attack on Pearl Harbor on December 7, 1941, the dock was not lost, but was quickly repaired and subsequently performed invaluable service both in the salvaging of vessels damaged in that attack and in the support of the fleet in the Pacific.

The other dock, the Dewey, was a 16,000-ton dock, built in three sections, and capable of docking itself. It was constructed in 1903-1905, also at Sparrow’s Point, Md., and was towed via the Suez Canal to the Philippines. The saga of this voyage is an epic of ocean towing history. The Dewey was still in service at Olongapo when the Japanese invaded the Philippines early in 1942. [sic: Preliminary landings took place as early as 8 December, with the main landings following on the 21st. Manila was occupied on New Years Day. — HyperWar] It was scuttled by the American naval forces before they abandoned the station.

Neither of these docks was suitable for mobile operation. Between 1920 and 1930, the Bureau of Yards and Docks made numerous studies of various types of mobile docks of both unit and sectional types. In 1933, funds were finally obtained for one 2,200-ton dock, and the Bureau designed and built the ARD-1. This dock was of revolutionary design. It was a one-piece dock, ship-shaped in form, with a molded closed bow and a faired stern, and may be best described as U-shaped in both plan and cross-section. The stern was closed by a bottom-hinged flap gate, operated by hydraulic rams. This gate was lowered to permit entrance of a ship into the submerged dock and then closed. The dock was then raised by pumping water from the ballast compartments and also from the main basin. This dock was equipped with its own diesel-electric power plant, pumping plant, repair shops, and crew’s accommodations. It was the first drydock in any navy which was sufficiently self-sustaining to accompany a fleet into remote waters.

The ARD-1 was towed to Pearl Harbor, where it was used successfully throughout the war. Thirty docks of this type, somewhat larger and incorporating many improvements adopted as a result of operational experience with this experimental dock, were constructed and deployed throughout the world during the war.

In 1935, the Bureau obtained $10,000,000 for a similar one-piece mobile dock, to be capable of lifting any naval vessel afloat. Complete plans and specifications were prepared by the Bureau for this dock, which was to be 1,027 feet long, 165 feet beam, and 75 feet molded depth. Bids received for this huge drydock, designed as the ARD-3, appreciably exceeded the appropriation, and the project was abandoned when the additional funds needed for its execution were refused.

At the same time, plans were prepared for the ARD-2, an improved and enlarged model of the ARD-1. It was not until November 1940, however, that funds were obtained for its construction, and the project placed under contract. The ARD-2, and an additional dock, the ARD-5, were completed in the spring of 1942. Additional docks of this type were built in rapid succession and were delivered during 1943 and 1944 at an average rate of more than one a month.

Types of Floating Drydocks

The war program of floating drydocks included a wide variety of types to meet the varying service requirements for which they were designed. The principal categories were as follows:

  • ABSD — Advance Base Sectional Dock. Mobile, military, steel dock, either (a) of ten sections of 10,000 tons lifting capacity each, or (b) of seven sections of 8,000 tons lifting capacity, for battleships, carriers, cruisers, and large auxiliaries.
  • ARD — Auxiliary Repair Dock. Mobile, military, steel unit dock, ship-form hull, with a normal lifting capacity of 3,500 tons, for destroyers, submarines, and small auxiliaries.
  • ARDC — Auxiliary Repair Dock, Concrete. Mobile, military concrete trough type, unit dock with faired bow and stern, 2,800 tons lifting capacity.
  • AFD — Auxiliary Floating Dock. Mobile, military, steel trough type, unit dock, with faired bow and stern, of 1,000 tons lifting capacity.
  • AFDL — Auxiliary Floating Dock, Lengthened. Mobile, steel trough type, unit dock, similar to AFD’s, but lengthened and enlarged to provide 1,900 tons lifting capacity.
  • YFD — Yard Floating Dock. This category included a wide variety of types, designed generally for yard or harbor use, with services supplied from shore. Among the principal types were 400-ton concrete trough docks; 1,000-ton, 3,000-ton and 5,000-ton one-piece timber trough docks; sectional timber docks ranging from 7,000 to 20,000 tons lifting capacity; and three-piece self-docking steel sectional docks of 14,000 to 18,000 tons lifting capacity.

These classifications were modified in 1946 in order to make the standard nomenclature of floating drydocks consistent and more descriptive. Four class designations were established, as follows:

  • AFDB — Auxiliary Floating Drydock Big.30,000 tons and larger.
  • AFDM — Auxiliary Floating Drydock Medium.10,000 to 30,000 tons.
  • AFDL — Auxiliary Floating Drydock Little. Less than 10,000 tons.
  • AFDL(C) — Auxiliary Floating Drydock Little (Concrete).

Under this modification, the ABSD’s were redesignated AFDB’s; the ARD’s became AFDU’s; the RDC’s became AFDL(C)’s; the AFD’s became AFDL’s; and the YFD’s became AFDM’s.

Advance Base Sectional Dock

The problem of providing floating drydocks capable of moving to advanced operational areas in the wake of the fleet, of sustaining themselves in full operation without support from shore, and of sufficient size and lifting capacity to dock all capital ships had been under study by the Bureau for many years. The ARD-3 was one solution of this problem. It was recognized that a unit dock of this size possessed certain disadvantages. In required a special basin of huge size for its initial construction. It was necessary to retain this basin in reserve or provide an equivalent basin elsewhere, for the periodic docking of the hull, since it was not self-docking. The towing of a craft of this size presented an operational problem of unprecedented magnitude. Provision for stresses during storms at sea required heavy reinforcement of the dock. Concern was felt over the possibility of losing the unit dock from enemy action while en route.

Studies had been carried on concurrently by the Bureau on various types of sectional docks, which would be designed with faired hulls for ease of towing and with joint details which would permit rapid assembly in forward areas under adverse conditions. These schemes were not carried to a final conclusion, primarily because the requirements of the Bureau of Ships for the longitudinal strength and stiffness of the assembled dock could not be met by an practicable form of joint.

When war was declared, it was apparent at once that a number of mobile capital-ship floating drydocks would have to be constructed immediately. The project was authorized and funds made available early in 1942. Studies in connection with the preparation of plans and specifications led to the proposal of a sectional type of dock, with field-welded joints, designed for a strength materially below that previously specified by the Bureau of Ships. This reduction was accepted, and the sectional type adopted.

Unwatering an Advance Base Sectional Dock

These docks were of two different sizes. For battleships, carriers, and the largest auxiliaries, the larger docks, consisted of ten section, each 256 feet long and 80 feet wide, and with a nominal lifting capacity of 10,000 tons. When assembled to form the dock, these sections were placed transversely with 50-foot outrigger platforms at either end of the assembly, making the dock 927 feet long and 256 feet wide overall, with an effective length of 827 feet, a clear width inside wing walls of 133 feet, and a lifting capacity of 90,000 tons.

The smaller docks, intended for all except the largest battleships, carriers, and auxiliaries, consisted of seven sections, each 240 feet long and 101 feet wide, with a lifting capacity of 8,000 tons. The assembled dock had an effective length of 725 feet, an overall length of 825 feet, a width of 240 feet, a clear width inside wing walls of 120 feet, and a lifting capacity of 55,000 tons.

At maximum submergence the 10-section docks had a depth over the blocks of 46 feet, with a freeboard of almost 6 feet; the 7-section docks had a corresponding depth of 40 feet and and a freeboard of almost 5 feet.

For both sizes, the sections were faired fore and aft to a truncated bow and stern, and could be towed at a speed of 6 to 8 knots without excessive power. In the assembled docks, the flat bows and sterns formed interrupted berths alongside to which barges and vessels could be readily moored.

Wingwalls are down to reduce wind resistance. Repair equipment is stowed on deck.

The sections consisted of the bottom pontoon and two wing walls, which were hinged at the bottom so that they could be folded inboard for towing, the purpose being to reduce the presentation to the wind and to lower the center of gravity as compared to fixed standing wing walls.

Each bottom pontoon of the battleship dock was 28 feet deep and was subdivided by two watertight bulkheads running lengthwise and four watertight bulkheads athwart the section to form twelve water ballast compartments and a central buoyancy compartment, 36 feet by 80 feet. This buoyancy compartment contained two decks, the upper deck being used for crew’s quarters, and the lower deck, for the machinery compartment. The double bottom was subdivided to form fuel-oil and fresh water tanks. Access to the usable compartments was provided by passageways under the upper pontoon deck which connected to stair trunks in the wing walls.

The wing walls were 20 feet wide and 55 feet high, and were subdivided by a safety deck set 14 feet below the top deck to form dry compartments above and three water ballast compartments below. The dry compartments were completely utilized for shops, storage, and similar facilities. Quarters and galleys were in the dry compartments in the bottom pontoons.

Each section was equipped with two 525-h.p. diesel engines directly connected to 350-k.w. generators, and with pumps evaporators, compressors, and heating and ventilating apparatus. No propulsion machinery was provided.

The smaller docks were similar, except that the bottom pontoons were 231/2 feet deep and the wing walls were 18 feet wide and 49 feet high.

Each dock was equipped with two portal jib cranes having a lifting capacity of 15 tons at a radius of 85 feet, traveling on rails on the top deck of the wing walls. In the case of the smaller dock, the cranes were set back from the inner face of the wing walls to provide clearance for overhanging superstructures of carriers, and the outer rail was supported on steel framing erected on the outboard portion of the pontoon deck.

ABSD Construction

The 58 sections required for these docks were constructed by five contractors at six different sites, including four on the West Coast, one on the Gulf Coast, and one near Pittsburgh on the Ohio River. Generally, they were built in dry excavated basins which were flooded and opened to the harbor for launching. In one case, two basins in tandem were utilized to suit local site conditions, and the sections were locked down from the upper basin, in which they were built, to the lower basin, the water level of which was normally at tide level and was raised temporarily by pumping.

At one yard, the sections were built on inclined shipways and end-launched; at another, they were side-launched. These sections were built in from 8 to 14 months. Maximum possible use was made of prefabrication and pre-assembly methods.

ABSD Assembly. — Although the wing walls were generally erected initially in their upright position for ease of construction, it was necessary to lower them to the horizontal position for towing at sea. On arrival at the advance base where they were to be placed in service, the wing walls were first raised again to their normal position and the sections then aligned and connected.

An ingenious method was evolved for the raising of the wing walls, which was found to be quicker and more certain than the scheme originally contemplated of accomplishing the result by the buoyancy process. Each wing wall was jacked into position, using two jacking assemblies, each consisting of a long telescoping box strut and a 500-ton hydraulic jack. Closely spaced matching holes were provided in the outer and inner boxes of the strut through which pins were inserted to permit holding the load while the jacks were run back after reaching the limit of their travel. These devices were also designed to hold back the weight of the wing walls after they passed the balance point during the raising operation. Two 100-ton jacks opposing the main jacks were used for this purpose. After the wing walls were in the vertical position, they were bolted to the bottom pontoon around their entire perimeter, and all access connection between the wing wall and bottom pontoon were made watertight.

The sections of each dock were successively brought together and aligned by means of the matching pintles and gudgeons which had been provided for the purpose on the meeting faces of the sections. Heavy splice plates were then welded in position from section to section across the joints at the wing walls, at top and bottom, and on both the inside and the outside faces of the wing walls. The strength of these connections gave the assembled dock a resisting moment of about 500,000 foot-tons, or approximately one-fourth that of the largest prospective vessel to be docked.

The drydock cranes were carried on the pontoon deck of individual sections during tow, and were shifted to their operating position on the wing walls during assembly of the dock by immerging the partially assembled dock, bringing the section carrying the crane alongside, and aligning it so the rails on the pontoon deck were in line with those on the wing walls of the rest of the dock. The trim and alignment were adjusted during the transfer by a delicate control of water ballast.

The assembled docks were moored at anchorages in protected harbors where wave conditions, depth of water, and bottom holding power were satisfactory. The large docks required at least 80 feet depth for effective use. They were moored by 32 fifteen-ton anchors, 14 on both side and 2 at either end, with 150 fathoms scope of chain.

In actual operation, it was found that the effectiveness of these docks could be improved by providing auxiliary facilities in excess of those available on the dock itself. A considerable number of shop, storage, and personnel accommodation barges were provided for this purpose.

Special Problems

Special conditions of service involved many entirely new studies and developments for our floating drydocks. For instance, as the docks had to operate in outlying areas where ideal conditions for operation could not always be met, it was necessary to give the adequacy of their moorings special consideration. In the largest size docks, this involved wind-tunnel experiments which gave some surprising results and indicated that a rearrangement of the moorings as originally planned was desirable. Also, as the drydock operating crews were initially relatively inexperienced and docking of ships under advance base conditions had never been attempted to the extent contemplated, it was necessary to prepare complete operating manuals for the use and guidance of the crews. Damage control was also important, and damage-control manuals were prepared for all advance base docks, covering every possible contingency of weather an enemy action.

As advance base docks were commissioned and had regular Navy crews and as they operated in areas where they had to be self-sustaining to a large extent, it was necessary to develop allowance lists for each type of dock and outfit them in much the same manner as a ship. This necessitated the incorporation into the docks of special facilities for the handling, stowage, and issuance of great quantities of material and equipment.

Complete statistics have not been compiled of the total number of vessels of all kinds from the mightiest battleship and carriers to the humblest patrol craft that were salvaged, repaired, and overhauled in this armada of floating drydocks. Themost dramatic demonstration of the importance of the mobile drydocks was given during the long drawn-out naval support of the invasion of Okinawa, when the fleet was subjected for weeks to continual and desperate “Kamikaze” attacks by Japanese suicide-bombers. The fleet suffered great damage, but the ready availability of the mobile drydocks at nearby advance bases, and the yeoman service rendered by their own crews and the ship repair components at these bases, save many ships and minimized the time ships were out of action for repairs, to such an extent that these docks may well have represented the margin between success and failure.”

I love LA 3

Regular readers know that once upon a time when the world was still dark with fears from the Soviets, a little known base in Scotland served as a portable pier for our submarine fleet. Starting in 1960, units of the United States Fleet anchored in a small inlet called Holy Loch that was just up from Dunoon. The submarine tenders that rotated in and out for the next 31 years all toiled endlessly to support the ballistic missile submarines and occasional fast attacks.

The other major unit was the floating sectional drydock that was known

as the USS Los Alamos (AFDB 7).

You can search theleansubmariner by looking for articles about her and understand just how important this asset was and how amazing the technology was that allowed her to serve for the entire time Site One was open.

A chance for a new life for a venerable name

The LA has been decommissioned for nearly twenty seven years as a Naval Unit but a unique opportunity has emerged that would pay tribute to the city that gave its name to this unit.

LOS ALAMOS, N.M. (AP) – New Mexico’s congressional delegation says the U.S. Navy’s next nuclear submarine should be named “USS Los Alamos” in recognition of the community’s contributions.

The delegation sent a letter to Navy Secretary Richard Spencer on Monday citing the founding of Los Alamos National Laboratory, the once-secret federal installation that helped develop the atomic bomb.

The letter refers to the heritage, service and scientific achievements of the northern New Mexico community.

This year marks the 75th anniversary of the founding of the lab, one of the nation’s premier nuclear weapons research centers. Aside from its role in the Manhattan Project, work at Los Alamos provided the technical understanding in nuclear energy that led to the Naval Propulsion Program.

The naming effort also has the support of the U.S. Senate Armed Services Committee.

Virginia Class Submarine

Of course I strongly support the efforts to bring back the name Los Alamos to the US Navy. My only hope is that in all the hubbub, the people who are pushing from the name don’t forget the mission the original LA performed. By providing remote dockings all of those years, she contributed so much to the nation’s defense.

Heritage means something to all of those who have served in the Navy.

This is one heritage that should not be forgotten.

A Bluejacket’s Memory 4

The Peacoat

I can think of few images that better represent an American Bluejacket more than the famous statue of a sailor in his peacoat with the collar turned up and his hands in his pockets. I remember the controversy when the Lone Sailor was first unveiled. Purists were quick to point out that the guy not only had his hands in his pockets but the buttons were undone and he generally looked a bit like a sailor on his way home that was tired of the sea. His grim expression seems to strengthen the notion that he was not the happiest person on the pier.

Yet in a moment, he captured the heart of many sailors that have left their home and served in what is best described as challenging to one’s soul and one’s physical being. Ever since man learned that a correctly designed craft could break the bonds with the land, men and now women have found the joy and the suffering that comes with the trip. And the boredom which probably occupies quite a bit of a sailors life.

The Navy announced last year that it was going to phase out the peacoat. I have to be honest and admit that I went through some emotional soul searching when the announcement was made. From a practical standpoint, the decision made some sense. After all, with modern fabrics and design capabilities, there are many more effective coats available that would exceed the ancient design and materials which make up the peacoat.

Yet, the coat is still listed in current Uniform Regulations

The Navy Peacoat

A double-breasted, hip length coat made of dark blue authorized fabric with a convertible collar, a set-in pocket in each forefront, and a single row of four 35-line black plastic anchor buttons down the right front and three on left. Men’s Peacoat buttons to the right.

So where did the coat get its name?

According to a 1975 edition of the Mariner’s Mirror, the term pea coat originated from the Dutch or West Frisian word pijjekker or pijjakker, in which pij referred to the type of cloth used, a coarse kind of twilled blue cloth with a nap on one side.

Another theory, which is mostly favored by the US Navy, is that the heavy topcoat worn in cold, miserable weather by seafaring men was once tailored from “pilot cloth” – a heavy, coarse, stout kind of twilled blue cloth with the nap on one side. This was sometimes called P-cloth from the initial letter of pilot, and the garment made from it was called a P-jacket – later a pea coat. The term has been used since 1723 to denote coats made from that cloth.

That’s a long time. That’s a lot of tradition. For a young man of eighteen years of age, being issued one of these was a family tradition. The coat I was issued was nearly the exact same coat as my Grandfather and my Father. In fact, one of my favorite pictures of Dad is when he was my age and stationed in the Finger Lakes Region of New York in the winter of 1945. I am pretty sure he was glad for the heavy wool in that very cold climate.

I thought about that coat a bit last night as I looked up at my Lone Sailor statue on the mantle. Not sure why other than the fact that the heat was blowing to overcome the weather outside. I remembered looking at the pile of clothes they had just issued me and coming to grips with the fact that this government issue outfit would be my main gear for the next four years. (I had no idea that it would stretch to more than twenty years at that point.)

It was June of 1972 and the Company was instructed to wear our cotton whites. But June of 1972 in Great Lakes was not a very warm time. In fact, it was colder there than parts of winter back in Pennsylvania. When we were in our off time (which wasn’t very often) that heavy coat actually came in pretty handy. I would find that to be true a number of times over the next few years.

The garment they gave me in boot camp smelled faintly like mothballs. There was a government label inside that had a place to write your name and number with a stencil pen. There was a precise way to fold it as well.

All Navy sailors learn quickly that space on boat a ship is very precious and limited so we had to learn the exact best way to fold our clothes. In the years since I have retired, I collect old Bluejackets Manuals and as far back as I can see with the ones I have collected, this folding thing has been around forever.

Some of the uniforms I was issued are long since gone from fashion. The Navy gave us something called utility uniforms. They were supposed to be more durable than dungarees but no one actually liked them. Frankly, they made us look like some kind of third rate Navy sea scouts instead of sailors. I was never so happy to ditch a uniform than when those went away.

The same with the miserable undress blues which were made of the coarsest and least wearable wool ever created. I often imagined some Senator made a killing by voting to provide unwearable wool to the Navy that came from his brother in laws chintzy factory.

The peacoat was special though. It was a lot like a wearable blanket. And a shelter from the wind and rain. The letter W comes to mind when I think back to that jacket.

Wool, Waterproof, Warm, Windproof, Wearable, Worldly

It was how we identified when we were out and about. In a crowd, you all looked the same or at least you did until you noticed that Petty Officer’s wore their distinctive rating badges. Those badges became something to strive for. A bluejacket for a bluejacket. It wasn’t armor but sometimes it felt like it.

I was glad for that jacket while I was in Great Lakes that Fall and early winter. I was even gladder when I went to New London for submarine school. But I quickly found that it was nothing more than a space absorber in my seabag when I went to Charleston. It didn’t make the trip to Hawaii not did it go with me as I sailed the oceans of the Pacific. I would use it in later years, but only when it was dictated.

I wore all kinds of foul weather gear as I changed submarines, homeports, and advanced through Chief to Chief Warrant Officer. I briefly toyed with the idea of getting a Bridge Coat when I went to Scotland but that never came to pass. It would have been a waste anyway since I soon transferred to an older submarine tender where I spent three years in an engine room surrounded by hot diesel engines and other equipment that tested the crew all of the time.

I still have the peacoat I was issued.

To be honest, it doesn’t fit anymore. I like to think that the wool has shrunken over the years but that’s a lie. Success and life have contributed to my girth increasing beyond the point where anything I once wore might even barely fit. Yet I can’t throw it away. Maybe someday when the nephews are cleaning out the junk form our house they will laugh a little at Uncle Bob’s tendency to hold on to stuff that no one cares about anymore. Kind of like the Navy wanting to get rid of the peacoats. No one seems to care anymore.

But I am glad to have the memory of being one of a long line of sailors who was identified by the Bluejacket I wore.

The Build – Reflections from an Old Docking Officer 3

The Build

When you have sailed on submarines for most of your career, stepping outside of your comfort zone reveals many things about who you are. Most submariners have achieved a level of excellence that is demanded by the profession. You are operating a large ship that is designed to sink and do most of its work undetected. That requires each person to be multi-talented in addition to being subject matter experts. You may be cooking one minute and helping to put on a band-it patch the next. Your watch could be as routine as pumping water from one tank to another then suddenly shifting into a battle stations mode where multiple responses must be made in a split second with no time to analyze.

In other words, you can get a little self-confident. If you get really cocky, you may just decide to take another path and become a Chief Warrant Officer. This program is designed for Chief Petty Officers who have no college degree but have a high degree of technical knowledge and advanced leadership skills. It has traditionally been highly selective and the billets are very limited. The year I was selected (FY 1989) there were only thirteen of us selected in my skill set out of a few thousand applicants.

I knew life was going to be different since instead of having a small division of men to care for, I would now have larger groups of men and women on board a ship that was not a submarine. I had no idea how different until I crossed the bow of the USS Los Alamos (AFDB 7) a large four section drydock in Holy Loch Scotland. When you first see her up close, you are struck by the size of the thing and the new challenge you are about to face.

Every ship and submarine is designed to sail the ocean with certain physical characteristics. But every ship and submarine also share one thing: they all need to come out of the water from time to time. When a ship is in the water, its hull is supported by the water that cradles it. Taking the water away means that all the weight will be shifted to another place and if it isn’t done properly, you could damage the ship itself or one of the many underwater components not visible when the ship is floating.

Someone has to create the build.

The Los Alamos was resurrected from a graveyard in Florida in the early 1960’s. She had been placed in storage at the end of World War 2 in the late 1940’s. When the new Polaris submarine program was introduced, the need for a portable servicing facility was determined. In this case, a small body of water on the west coast of Scotland was deemed suitable. For that reason, the Site One base in Holy Loch was created. Four sections of the dock were towed to the Loch and assembled by Seabees. That dock commenced operation within a short period of time and did hundreds of routine and emergency dockings over the next thirty years.

When a ship or submarine is designed, it comes with plans for building and plans for docking as the need arises. The submarines that Los Alamos had been designed to support were built at the same time and after she was reactivated. SO needless to say, they plans we had for each boat were really worn and aged by the time I reported on board. The Navy had sent me to Connecticut to train on a dock that was a lot more modern and not a sectional dock. But the principles remained the same. You had to understand weights and measures, metacentric heights, and the importance of the build.

Each build is slightly different, even on the same class of boats. Some had different equipment, some had seawater openings in different places and all had to be examined carefully in order not to damage the boat when you land it. Most importantly, all of the calculations for block heights had to be precise. Then you had to have a plan on how to land the boats exactly where you built the blocks. The time needed to create a build plan was at least a week. You take the old plan and verify that no changes have occurred. Then you painstakingly set up the height measures for each of the wooden blocks that will be built. The carpenter shop then cuts each block to your specification and prepares them to mount on the base blocks. You also need to calculate the measurements for the side blocks that will be shifted in place to prevent the boat from accidently rolling over.

There is little room for error.

These wooden blocks are designed to crush with the weight but they have a designed factor that allows for uniform crush. Once the calculations are complete, the build begins. Men and women from the docking department work day and night alongside the deck division to place the blocks and caps in their proper place. The last step is when the Docking Officer personally measures each part of the build and certifies it.

All of this work occurs in a variety of weather. All year long. In Scotland, that can mean anything from freezing rain to blinding snow storms. The schedule rarely was interrupted by weather. Many times the boat needed more than a routine repair so we just did what we did.

Apparently someone thought he was Captain Morgan

The day comes when all is ready and the floating drydock submerges in place. You do that by flooding the dock down until it is low enough to accept the submarine or ship that is waiting to cross her brow on the open end. The Captain and Docking Officer are on the Flying Bridge opposite of the open end and everyone on the dock is in place ready to receive the ship. When the nose of the submarine enters the dock area, the Docking Officer becomes legally responsible for the safety of the unit. It means bringing her in safe and not scraping the walls, setting her down correctly with having it fall over, and ensuring that this multi-million dollar warship will be safely landed and able to be restored to fighting condition in a few weeks.

No pressure at all.

March 15, 1991 was my qualification docking. It was an incredible feeling to finally land the boat and the tugboat that we landed at the same time (two units at once was pretty common for the Los Alamos).

It was the longest day of my life and certainly one filled with exciting things no one had planned. The docking took a little longer and while we were bringing the boats in a sudden squall appeared. That wind tried to knock our two charges all over the dock before we could land them. But the crew of the dock did a marvelous job.

A party had been planned by the wives for the event over at our house on shore. Since the docking was delayed about eight hours, the party started without us, But when we finally finished, the crew assembled at my house and we commenced a celebration for the ages. It did not end until the next morning. Most of us had to go back to work and believe me there were a few hurting sailors and officers that day. But it was a successful landing and that meant the world to me.

Sadly the announcement that the dock was to be closed down after 31 years came not too long after that. I was able to do five dockings before the end but the lessons have stuck with me ever since:

  1. To have a good build, you have to have a good crew. I was honored to have some of the best people I have ever worked with on that dock.
  2. The most expensive ship in the Navy still relies on a solid foundation. The build must be carefully created and designed for the worst possible scenario,
  3. Stepping outside of your comfort zone is the only way to find out who you really are. Being a long time submariner gave me confidence in one area but may have actually been keeping me from reaching my potential

The engineers that originally designed the sectional floating drydocks would have had no way to foresee the impact of their design on future operations. The first atomic power plant was not even commissioned until 1948. But the core principles of safely docking a vessel stand the test of time. I salute all of the unsung heroes of the Cold War that operated in the worst conditions of all but helped protect America from those who wanted to destroy her.

Primus in Pace – USS George Washington SSBN 598 Reply

Post #598: Primus In Pace

If you cross parts of the great American prairie, you can still see the ruts of the wagons that crossed the vast wilderness on their way to the west. Those ruts have been superseded by ribbons of concrete and asphalt that stretch from sea to shining sea and remind you of where we have been and where we have yet to go.

On the other hand, you can scour the oceans as long as you want and you will never find evidence that the mighty submarine warship USS George Washington was there. From the minute she started her first underway in 1960 until she was decommissioned on January 24, 1985, her path was largely undetected with a few notable exceptions along the way. That part of her story was long after I left her and will remain for another day.

My Qual Boat : 1974

Any submariner that follows the story knows that she was the lead class of the first Polaris submarines.

These submarines paved the way for the group of boats known as the “Forty One for Freedom” boats.

Each succeeding hull number series brought greater capabilities and more powerful weapons. But through it all, the Georgefish sailed on and played her role. She sailed in the Atlantic and the Pacific and places unknown for a few generations of sailors. I was assigned to be an Auxiliaryman in 1973 and spent two years learning about the boat, about submarining in general and about myself. I would like to say I did things that were heroic and memorable but that would be a lie. Like most submariners of that age, I mainly just did my job.

Interesting map found at the Sub Base Museum in Groton depicting the missile ranges of the various classes of FBMs

 

Not that there weren’t interesting times. We sailed out of Guam and I the early seventies, Guam and Mother Nature treated us to a couple of typhoons. The Vietnam War was ending and the Cold War was heating up so we had a lot of company on our way into and out of Guam. Those Soviet fishing boats liked to show us how well they could navigate while listening for telltale signs of submarine sounds. Even when we got on station, we knew that there would be great challenges. Submarines sometimes came closer to the surface for different reasons and the enemy had many faces. Some of those faces were actual patrolling craft and sometimes the enemy took the form of great open ocean storms.

The new kid

When I first reported aboard, I learned about how life is ordered. If you are new and not qualified to do anything, sleeping was more of a rare privilege than a right. You can’t imagine how low you are on the food chain until you have to clean out the trash compactor room with all of the smells that still manage to come back after over forty years. When things need to be quiet, trash accumulates quickly and the stench fills your nose. There really is no place to go that you can avoid that odor when you are working in the scullery so you just learn to talk yourself out of being sick.

The bunk that I was assigned was directly below the scullery. Since the scullery wasn’t watertight, often the liquids would come down the long shaft of the TDU (trash disposal unit) and settled near where I slept (when I actually got to sleep). I have to be honest, I was not aware how lucky I was to have a rack at the time but in retrospect, I remember being extra careful to clean my space and keep it spotless.

After a tour as a mess cook, it’s off to the helms planes station. Compared to the diving stations I see on the modern boats, ours looked like something out of an ancient handbook. We had manual depth counters, a rudder angle indicator, an actual bubble inclinometer and two colors: white when it was light and red lights when it was rigged for red. You learn what ultimate boredom is and sheer panic is while sitting in the same seats. You also learn to control them both. The boredom on an old boomer is traveling at a set speed for days on end, sometimes varying your depth, always following the compass to you next path. We kept ourselves awake with cigarettes and coffee and hot cocoa. We learned old sailor stories from the more seasoned Petty Officers, Chiefs and sometimes Officers that kept us company on our long drive to nowhere.

Man Battle Stations – cue the really annoying electronic alarm

Then there would be the moments of stress. Battle Stations Missile, Battle Stations Torpedo, Collision Alarms, Fires and flooding in some of the most unusual places. Mostly drills but you didn’t always know it. You went from practically asleep to wide eyed and alert in moments as everything around you changed too. Headphone would be manned, communications between missile control, engineering and the torpedo room would come rattling across like bullets from a machine gun. During all of these, you kept focus on what was in front of you.

In some cases, your rudder or planes would no longer function properly. We drilled on the back up process which was incredibly old fashioned and manual. Minutes seemed like hours. Somewhere, hundreds of feet behind you, shipmates who just minutes before may have been sleeping or eating were struggling to activate an emergency backup system and restore the ship.

There was no place to go.

When an actual casualty did occur, all the discipline and practice kicked, almost as if directed by unseen hands. Men knew where to go and what equipment they would need. We practiced in the dark just in case the lights were out. We knew where every twist and turn was located so that we could get through the maze of equipment without becoming casualties ourselves. Your heart would be racing a hundred miles an hour as you took your position but you were there. Waiting if needed but ready.

It paid off more times that I can tell you. The Georgefish was well worn by 1974. She had some shipyard time for repairs and upgrades in weapons systems, but some things just fell below the radar. So when she found herself in a Northern Pacific monster storm and had to go up for a communications pass, she got to test the designer’s abilities and the builder’s skills.

The wave

I do not know what the size of the waves were that came rolling over us in a series of loud canon shots. I do know that the boat inclinometer was clearly indicating that every other swell took us to forty five degrees. I do know that it was black as night and the Officer of the Deck kept saying he couldn’t see a damn thing. The rudder was nearly useless in trying to keep us on course and we popped to the surface where we remained for the next twenty minutes. We were caught in a surfacing effect between the wave troughs. The missile deck superstructure was higher than the pressure hull and it worked as a magnet holding us fast on top. Then came “the wave”. It was horrendous and sounded like the loudest clap of thunder I had ever heard. I was standing back fro the dive stand near the officer of the deck when I heard the loud spraying noise coming from somewhere in front of me. Followed by loud yelling of the men caught in its path. We had all been taught from the very first that flooding and fires kill people first and submarines second.

Just at that moment, the Captain came into the control room and turned the lights on. He said, there is no use having the lights off officer of the deck, you can’t see anything. Then he took the deck and the Conn. Sizing up the situation quickly he saw what had happened. The hydraulic supply line to the ram that controlled the fairwater planes had a small blow out plug in it that was supposed to protect the lines in case of over pressurizations. It worked. The 3000 PSI supply line was over pressurized when the wave forced the fairwater planes to fight against the ordered position. It did exactly what it was supposed to.

My Chief was the Chief of the Watch and he isolated the line stopping the flow of oil. The planes were now frozen in the “rise” position. Both the inboard and outboard planesmen were covered with hydraulic oil so they were relieved and sent below. That left me (as the messenger) the only choice to sit in the outboard station and the rudder was shifter over. They were cleaning up the oil all around me as the boat continued to rock and I tried to control the rudder.

The Captain ordered a massive amount of water flooded into the variable ballast tanks. Thousands and thousands of pounds of cold sea water made the boat heavier and heavier until finally, we broke the grip the ocean held on us. Now the boat began to sink quickly and as we passed 150 feet, the reactor gave up the ghost. The main propulsion for the boat comes from that single screw driven by the steam created in the reactor. But all of the wild gyrations on the surface must have affect the plant. Without that power, the huge pumps needed to get rid of all that extra water would have to sit and wait. Restoring power would take everything.

Fairwaters jammed on full rise

As the boats downward speed increased, I remember hugging the stern planes yoke to my chest. Full rise. Trying to take advantage of any residual speed still left on the no longer responding screw. My eyes were glued to the dial that showed us slowly sinking closer and closer to test depth. I was only nineteen. I really didn’t want to die. But I also didn’t want to let go of that yoke. The Captain was behind me watching the same thing.

As we approached test depth, maneuvering called on the 2MC and reported that the reactor was back on line and propulsion was being restored. We were moments away from having to do an emergency blow. If that had failed, we would have been a worse disaster than the Thresher. I didn’t think about that at the time. I just kept asking God to keep us alive. The next few hours were a blur. We came back up from the deeps and had to porpoise the boat. The fairwater planes were still stuck on full rise so I had a depth band of about 75 feet to play with. I think I got pretty good at it as they came up with a replacement blowout plug and restored the planes. I finally got relieved and was so very happy to just go and lay my head down for a while.

The remainder of that trip was unremarkable. It’s funny how that works. When we returned to port and gave the boat to the Gold Crew, I was still in a bit of a haze. I wasn’t really sure I ever wanted to go back to sea. But I did. There were more adventures and other casualties along the way. A few fires, an Oxygen generator rapid depressurization, and losing the rudder ram when the end cap sheared off during another storm.

A different kind of war, a different kind of warrior

Some people will say that we weren’t in a war. Fair enough. The work that many of us did was far from anything that resembled Vietnam of the Gulf Wars. I would never try and take anything away from anyone who has served in active combat where you don’t know from minute to minute if this is your last. I didn’t see my first Russian Officer face to face until a few years after I retired when a former Soviet Submariner came to Kansas on a trade mission shopping for deals on wheat. He seemed nice enough.

Our only real claim to fame was that in all the years we sailed, not a single missile flew with a hostile intent in mind. Lots of practice shots along the way but the very fact that we could not be pinned down must have given old Ivan a lot to think about all those years. For all of his craziness, he wasn’t too bad of an enemy. He at least understood that the one nation that has actually used nuclear weapons had enough to make any victor just as much as a loser.

 

Saying Goodbye

I was stationed in Bremerton when the Georgefish showed up for decommissioning. A lot of water had travelled over both of our hulls by that time. I have the distinction of sailing on the first SSBN and the first Trident USS Ohio. I can assure you that the difference was dramatic. Both filled the same role but the destructive power of an Ohio Class boomer is breathtaking.

It was a very cold day in January 1985. I have no idea how the Navy found out that I had been a young sailor on the Georgefish but I got a personal invitation. She looked odd sitting next to the pier with no missile compartment. I felt a loss it is hard to explain. That feeling would return decades later when I stood on the hill looking at her sail in Connecticut. But all things come to an end. Except the stories. Those will live long past the boat or the men who sailed on her.

 

My life was profoundly influenced by my association with the men and women of America’s submarine program. I would not trade the experience for any other kind of experience the world has to offer.

I am also profoundly grateful to those who taught me, accepted me as one of their own, and made sure that we never left ruts in the ocean.

Today’s post is about an odd numbered submarine that played a unique role in the development of the nuclear Navy, the USS Tulibee.  I am always reminded when I do stories about the nuclear submarine Navy that there has never been a point in my life that the United States did not have a nuclear submarine. I was born in the cradle of the Nuclear Navy (Pittsburgh not New London) in 1954 and had family members that worked at Bettis Atomic Energy from the very start.

From an article on Global Security.org

“In 1956 Admiral Arleigh Burke, then CNO, requested that the Committee on Undersea Warfare of the National Academy of Sciences study the effect of advanced technology on submarine warfare. The result of this study, dubbed “Project Nobska” was an increased emphasis on deeper-diving, ultraquiet designs utilizing long-range sonar. The USS Tullibee incorporated three design changes based on Project Nobska. First, it incorporated the first bow-mounted spherical sonar array. This required the second innovation, amidships, angled torpedo tubes. Thirdly, Tullibee was propelled by a very quiet turboelectric power plant.”

The Soviets were already developing boats that combined speed and diving ability. That ambition would remain one of their driving goals throughout the Cold War. Some of their later boats were rumored to seceded the diving capability of Allied Submarines by a significant amount. So Tullibee was an early recognition by American planners for the need for stronger ASW capability and operational improvements.

“Naval Reactors’ effort to develop a quiet nuclear propulsion plant began early — even before the sea trials of the Nautilus — with the hunter-killer submarine Tullibee (SSN 597). The purpose of the hunter-killer was to ambush enemy submarines. As the mission of the ship was seen in the early 1950s, speed was less important than silence. By substituting an electric-drive system for reduction gears, Rickover hoped to reduce noise. In this approach a generator ran an electric motor. Varying the speed of the motor would achieve the same result as the reduction gear, but there would be a penalty; the electric propulsion system would be larger and heavier than the components it replaced.

On 20 October 1954, the Department of Defense requested the Atomic Energy Commission to develop a small reactor for a small hunter-killer submarine. The ship was meant to be the first of a large class. The commission, wishing to broaden industrial participation in the program, assigned the project to Combustion Engineering, Incorporated. The S1C prototype achieved full power operation on 19 December 1959 at Windsor, Connecticut. Congress authorized the Tulibee in the 1958 shipbuilding program, Electric Boat launched the ship on 27 April 1960, and the navy commissioned her on November 9 of that year. The ship was not small; although her tonnage, beam, and draft were less than the Skipjack, her length was greater. By the time the Tullibee was in operation, she was about to be superseded by the Thresher class.”

“Tullibee combined the ASW focus of the SSKs with the smallest nuclear reactor then feasible with an eye toward a relatively cheap, dedicated ASW asset that could be deployed in the numbers still considered necessary to fully populate the forward barriers. Compared to the 15,000 SHP S5W type reactor of a Skipjack, Tullibee had a 2500 SHP reactor and turbo-electric drive. She could barely make 20 knots, but she lacked the reduction gears whose loud tonals made prior SSNs so easy for SOSUS to detect at extreme range. She also continued the tradition established by the BQR-4 equipped SSKs by mounting a large, bow mounted, passive, low frequency array, the BQR-7. On Tullibee, the BQR-7 was wrapped around the first spherical active sonar, the BQS-6, and together they formed the first integrated sonar system, the BQQ-1.

Superficially, the Tullibee appeared to be one of the blind alleys into which technological evolution occasionally wandered. Nevertheless, the ship was important. To get good reception, her sonar was placed far forward, as far away from the ship’s self-generated noise as possible. Her torpedo tubes were moved aft into the midship section and were angled outward from the centerline—features that were incorporated in the Thresher submarines.8 Finally, electric drive worked well; the submarine was the quietest nuclear platform the Navy had.

As an ASW platform her performance was unmatched, but almost as soon as the decision to deploy Tullibee was made, a further decision was made to avoid specialized platforms and pursue instead a multipurpose SSN that best combined the speed of Skipjack and the ASW capability of Tullibee into one platform. This became the USS Thresher.”

The Tullibee had a good career lasting from the early sixties into the late 1980’s. She was superseded by a number of classes but the work done on her would impact most of those classes. Tactics leaned in those early days would help the newer boats to understand the opportunities that existed for modern nuclear submarine warfare.

Decommissioned and stricken from the Naval Vessel Register on 25 June 1988, ex-Tullibee entered the Navy’s Nuclear Powered Ship and Submarine Recycling Program on 5 January 1995. Recycling was completed on 1 April 1996. One of the fairwater planes from the Tullibee can be seen as part of a permanent art installation on the shore of Lake Washington in Seattle.

To all who built her and sailed on her, Brazo Zulu.

Random Thoughts from theleansubmariner… I lived 3

I lived.
I could have chosen to stay in my hometown and learned a trade. I could have hidden from life’s greatest challenges and been safe. But instead…

I lived.
I could have worked harder to gain acceptance to a fine educational institution and maybe be part of a fraternity that I could look back on years later and think how special I was. But instead…

I lived.
I lived on a boat that was designed to defy the sea and all its challenges. I lived a life of sacrifice that often defied logic. Many of the people I lived it for didn’t even know I was doing it. Or cared. And hardly appreciated the gift. But despite that…

I lived.
I lived with men who left their own families and personal freedom to protect total strangers. I lived with them in a world surrounded by darkness and enemies of every kind. We saw some amazing things and we remained silent through it all. And because of that…

I lived a life worth living. A life that has sustained me through my later years. When the Angels call me home and ask me what I did, I only have one response.

I was a Submariner. I lived.

The Madness of Crowds 6

“In reading The History of Nations, we find that, like individuals, they have their whims and their peculiarities, their seasons of excitement and recklessness, when they care not what they do. We find that whole communities suddenly fix their minds upon one object and go mad in its pursuit; that millions of people become simultaneously impressed with one delusion, and run after it, till their attention is caught by some new folly more captivating than the first.”

― Charles Mackay, Extraordinary Popular Delusions and the Madness of Crowds

I was seventeen on April 23rd 1972 when I enlisted in the Delayed Entry Program for the United States Navy.

I turned eighteen when they put me on a plane bound for boot camp. Since the time that I was very young, I had wanted to be a sailor and even the long drawn out years of the Vietnam War had not dissuaded me from my calling. To be honest, I just wanted to find my place in the world.

In Boot Camp, they issued us all new clothes to go with our spiffy haircuts. We quickly learned the fine art of shining your boondockers to a perfect shine, how to wash clothes in a long sink and dry them on a line and oh by the way, they issues us all rifles.

Now to be fair, the rifles they gave us had no firing pins. They were surplus 1903 A3 Springfield Rifles and at the end of each drill we put them back in their racks. The purpose was to teach us responsibility, strengthen our arm muscles and teach us a little bit about discipline. It worked too. You learned quickly that even an inert weapon could get you in a lot of trouble if you neglected it. The manual of arms indeed toughened you up and on the very rare occasion you had to hold in in front of you or over your head while running, you discovered what true discipline meant.

We did practice with actual weapons too. But since it was the Navy, nothing automatic and nothing that would get you in much trouble. That would come later when we went to our various assignments. I was still eighteen when I graduated from Boot Camp along with hundreds of other young men in Great Lakes, Orlando and San Diego. Many of them would go to ships and boats that still plied the waters off of Vietnam. Many of those would be issued weapons or be part of a gun crew. In 1972, eighteen year olds were still being called upon to fight wars. Come to think of it, that’s still true today. More on that later.

We didn’t have the internet back then but I was a pretty avid reader. My memory is a little hazy from that time, but I don’t ever remember hearing about any mass killings stateside. Despite the fact that we had all these trained eighteen year olds running around with Army, Navy, Marine and Air Force Training, there just weren’t that many mass killings. Come to think of it, there weren’t any Coasties shooting up towns either.

I was nineteen the first time I fired a machine gun. It was an old Thompson .45 and I only got to fire it a few times. Same with the shotguns, Colt 45 pistols, and later the M-14 and M-16. To be accurate, I didn’t get my first crack at an M-16 until I was in my twenties. But I made up for it later in life when I purchased a civilian version of the M-4. Maybe I shouldn’t say this since it might scare some people, but I knew a lot of nineteen and twenty year olds that worked on missiles and torpedoes. I won’t tell you what kind of missiles but you can look them up. Some of them had names like Polaris, Poseidon and Trident. To the best of my knowledge, no one ever used one of those weapons in any way that wasn’t planned.

In all those years since I was seventeen, neither I nor any of the weapons I handled ever killed a single thing. Not one. I was an armed watchstander on many submarines and a few ships and carried pistols and shotguns fairly regularly. I just never had to use them. Since I retired, one of my hobbies is target shooting. I’m probably not as good as others I know but I still enjoy the sport. It’s not a cheap hobby by any means. But it’s one that I enjoy. I also enjoy knowing that I am part of a tradition that goes back hundreds of years. The tradition of freedom and supporting the laws that have kept this country strong.

This week, people are reacting with emotion and fear to a horrible tragedy. It’s one of a few that have happened over the past ten years and the press and anti-gun people are throwing around the usual words they use when they want to ban freedom. “Sensible” and “Common Sense” laws are always a bit disingenuous to me because they are typically driven by emotional responses to symptoms and not the root cause. “Why does anyone need an AR?” is the latest battle cry of the left. They don’t own them, most have probably never shot one, so they can’t understand why so many people want to own them. Maybe that’s a fair question.

The fear of the weapon is deeply ingrained in some. It’s scary looking to the uninitiated. Black and sleek, this weapon can hold a magazine that often carries thirty rounds. It looks just like those assault rifles (whatever the hell that is) they see on their police shows where large men with SWAT vests come charging around the corner. But knowing modern weaponry like I do, the AR is just the scary public face of an entire class of guns that hold multiple rounds. Most are used for hunting or ranching out west and don’t have the look of a “weapon of war” as I heard one child say today. But they have the exact same capacity for destruction in the wrong hands.

In all of the years that many of us have owned multiple round weapons, none of the people I know have ever gone on a rampage. Not one. There are millions of these rifles and rifles similar to them in circulation today. But the only time we hear of shootings like this are when people with mental issues break the laws and obtain them to use for evil. No gun law ever developed will stop a mentally deranged individual from killing innocent people. Because even with the incredibly strict laws we have now, none ever has. The key word here is “Individual”.

The talk today turned to trying to limit the age of who can buy a gun. I have heard people say a few times on the news that no eighteen year old should be able to buy a rifle. Seriously??? This is the solution? Maybe we should also not send any more boys off to fight for our country either. But you would have to go back to wipe history from the pages of our freedom. Those boys landed on Omaha Beach and freed Europe. Those boys stopped the Japanese from driving their ships into San Francisco Harbor. And for the forty five years of the Cold War they protected this country from all manner of threats. They have sacrificed themselves in Iraq and Afghanistan and so many other countries around the world for freedom sake.

I cannot stand idly by while politicians and pundits wash away our rights. As horrible as the recent tragedies have been, they are not addressing the root cause. We have allowed parents to not parent, kids to run absolutely wild while society tears itself apart. We have allowed the fabric of society to be torn apart with so much lack of discipline that it is little wonder that mental cases like that idiot who shot up the latest school have been allowed to slip through the cracks. Let’s work on that before we go down a path of destroying the legitimate rights of law abiding citizens.

But I fear this time we won’t.

We don’t want to hurt anyone’s feelings. We don’t want to hold anybody accountable. We want to show how progressive we are and that society is better than what we actually are. We won’t stand up because we are afraid to get shouted down by the hysterical people who don’t want to admit that not every child deserves a trophy and some of them are seriously flawed. The NRA is an easy target and so are the rights of people you don’t agree with. But once we have gone down that road, there will be no return. The slippery slope will be a raging torrent of destruction to all of your rights. The only difference this time is that you won’t have a gun to stop an oppressive force.

America’s strength does not lie alone in the fact that we have the ability to defend ourselves. America’s strength is based on the strength of individuals who have banded together for the common pursuit of life, liberty and the pursuit of justice. Individuals who get up every morning and take responsibility for their own actions. Individuals who have the ability to contribute to the common defense of what makes us strongest – Our Freedoms. There is no age limit on that desire for freedom.

A lot of eighteen year olds paid the ultimate price to protect those rights.

They probably don’t teach that in schools nowadays.

Birth of the Boomers 2

Happy New Year from TLS

I have been doing a lot of research on my WW2 projects and came across a great source of information.

The Navy publishes a monthly magazine that dates back to the 1920’s under a variety of names including “All Hands Magazine”.

Now for something completely different

I was thinking about how submarines have changed and of course one of the real milestones in submarine operations was the creation of the Polaris Program. This is one of those game changing moments in many ways. While the boats were built using methods that dated to the Fleet Boats, the marriage of a new power and propulsion system and brand new form of weapon fundamentally changed submarine warfare as well as global warfare. While earlier systems had been developed to attack the enemy ships and territory (Regulas for instance) Polaris provided a multiple survivable weapon that would be difficult to detect.

From the Nautilus on, submarines had already proven their new stealth technology. No longer would boats be required to come to the surface (or near to the surface while snorkeling) on a regular basis. These new vessels became true submarines in the sense that they could operate for months at a time and perform all of their designated missions. These boats could provide enough air and water and habitability was greatly improved. Most importantly though, the purpose of the boat was more than adequately met. The 41 for Freedom boats would contribute greatly to the winning of the Cold War (at least the first one).

The USS George Washington SSBN 598 was commissioned on December 30, 1959. The January “All Hands Magazine” chronicled the development of the weapons systems and boats that would follow as the nation geared up for this newest phase of the Cold War. The engineering and production capabilities that were needed to accomplish these tasks stand as monuments to American ingenuity to this day.
