USS George Washington SSBN 598 – First and Finest 1

Just a short history of the submarine I qualified on 44 years ago.

 

A Global Cold War Warrior

USS George Washington (SSBN-598) was the United States’ first operational ballistic missile submarine. It was the lead ship of her class of nuclear ballistic missile submarines, was the third United States Navy ship of the name, in Honor of George Washington (1732–1799), first President of the United States, and the first of that name to be purpose-built as a warship.

George Washington’s keel was laid down at Electric Boat Division of General Dynamics, Groton, Connecticut on 1 November 1958. The first of her class, she was launched on 9 June 1959 sponsored by Mrs. Ollie Mae Anderson (née Rawlins), wife of US Treasury Secretary Robert B. Anderson, and commissioned on 30 December 1959 as SSBN-598 with Commander James B. Osborn in command of the Blue crew and Commander John L. From, Jr. in command of the Gold crew.

George Washington was originally laid down as the attack submarine USS Scorpion (SSN-589). During construction, she was lengthened by the insertion of a 130 ft (40 m)-long ballistic missile section and renamed George Washington; another submarine under construction at the time received the original name and hull number. Inside George Washington’s forward escape hatch, a plaque remained bearing her original name. Because the ballistic missile compartment design of George Washington was intended to be reused in later ship classes, the section inserted into George Washington was designed with a deeper test depth rating than the rest of the submarine.

George Washington left Groton on 28 June 1960 for Cape Canaveral, Florida, where she loaded two Polaris missiles. Standing out into the Atlantic Missile Test Range with Rear Admiral William Raborn, head of the Polaris submarine development program, on board as an observer, she successfully conducted the first Polaris missile launch from a submerged submarine on 20 July 1960. At 12:39, George Washington’s commanding officer sent President Dwight Eisenhower the message: POLARIS – FROM OUT OF THE DEEP TO TARGET. PERFECT. Less than two hours later a second missile from the submarine also struck the impact area 1,100 nmi (1,300 mi; 2,000 km) downrange.

George Washington then embarked her Gold crew, and on 30 July 1960 she launched two more missiles while submerged. Shakedown for the Gold crew ended at Groton on 30 August and the boat got underway from that port on 28 October for Naval Weapons Station Charleston, to load her full complement of 16 Polaris missiles. There she was awarded the Navy Unit Commendation, after which her Blue crew took over and embarked on her first deterrent patrol.

The submarine completed her first patrol after 66 days of submerged running on 21 January 1961, and put in at Naval Submarine Base New London at New London, Connecticut. The Gold crew took over and departed on her next patrol on 14 February 1961. After the patrol, she entered Holy Loch, Scotland, on 25 April 1961.

In 1970 ten years after her initial departure from Groton, George Washington put in to refuel in Charleston SC, having cruised some 100,000 nm (120,000 mi; 190,000 km). George Washington shifted to the United States Pacific Fleet and a new home port at Pearl Harbor, Hawaii after the refueling.

On 9 April 1981, George Washington was at periscope depth and was broadsided by the 2,350 long tons (2,390 t) Japanese commercial cargo ship Nissho Maru in the East China Sea about 110 nmi (130 mi; 200 km) south-southwest of Sasebo, Japan. George Washington immediately surfaced and searched for the other vessel. Owing to the heavy fog conditions at the time, they did see the Nissho Maru heading off into the fog, but it appeared undamaged. After calling out for a P-3 Orion to search for the freighter, they headed into port for repairs; the crew was later flown back to Pearl Harbor from Guam. Unbeknownst to the crew of the George Washington, Nissho Maru sank in about 15 minutes. Two Japanese crewmen were lost; 13 were rescued by Japan Maritime Self-Defense Force AkiGumo(ja) and Aogumo(ja). The submarine suffered minor damage to her sail.

The accident strained U.S.–Japanese relations a month before a meeting between Japanese Prime Minister Zenko Suzuki and President of the United States Ronald Reagan. Japan criticized the U.S. for taking more than 24 hours to notify Japanese authorities, and demanded to know what the boat was doing surfacing only about 20 nmi (23 mi; 37 km) outside Japan’s territorial waters.

The U.S. Navy initially stated that George Washington executed a crash dive during the collision, and then immediately surfaced, but could not see the Japanese ship due to fog and rain (according to a U.S. Navy report). A preliminary report released a few days later stated the submarine and aircraft crews both had detected Nissho Maru nearby, but neither the submarine nor the aircraft realized Nissho Maru was in distress.

On 11 April, President Reagan and other U.S. officials formally expressed regret over the accident, made offers of compensation, and reassured the Japanese there was no cause for worry about radioactive contamination. As is its standard policy, the U.S. Government refused to reveal what the submarine was doing close to Japan, or whether she was armed with nuclear missiles. (It is government and navy policy to neither confirm nor deny the presence of nuclear weapons on board.) The Navy accepted responsibility for the incident, and relieved and reprimanded the George Washington’s commanding officer and officer of the deck.

On 31 August, the U.S. Navy released its final report, concluding the accident resulted from a set of coincidences, compounded by errors on the part of two members of the submarine crew. After the collision with the Nissho Maru, the damaged sail was repaired with parts from the sail from the USS Abraham Lincoln which was waiting for disposal at the Puget Sound Naval Shipyard.

In 1982, George Washington returned to Pearl Harbor from her last missile patrol. In 1983, her missiles were unloaded at Bangor, Washington to comply with the SALT I treaty. George Washington made 55 deterrent patrols in both the Atlantic and Pacific oceans in her 25-year career

George Washington continued service as an attack submarine (SSN), returning briefly to Pearl Harbor. In 1983, she departed Pearl Harbor for the last time and transited the Panama Canal back to the Atlantic and to New London. George Washington was decommissioned on 24 January 1985, stricken from the Naval Vessel Registry on 30 April 1986, and scheduled for disposal through the Ship-Submarine Recycling Program at Puget Sound Naval Shipyard. Recycling of the ship was completed on 30 September 1998.

George Washington’s sail was removed prior to disposal and now rests at the Submarine Force Library and Museum at Groton, Connecticut.

August 28, 1973 The Journey Begins 13

I joined the Navy in April of 1972 by raising my right hand for the very first time. The Navy used the Delayed Entry Program to pre-sign willing young volunteers and at the age of seventeen, I was anxious to leave home and see the world. I remember my girlfriend at the time crying a bit and shortly before I joined, President Nixon escalated the bombing of NVA troops and Hanoi. On the day I signed up, 100,000 people in various cities around the United States protested the increased bombing. Needless to say it was not a great time to be in uniform. The support for the military was further diminished by various scandals and secret bombing campaigns were being revealed by the press on a regular basis.

In December 1972, I was finishing up Machinist Mate A school in Great Lakes Illinois while President Nixon ordered the launch of the most intense air offense of the war: Operation Linebacker. The attacks, concentrated between Hanoi and Haiphong, drop roughly 20,000 tons of bombs over densely populated regions. The outcry both here and abroad was fierce but it achieved the goal of bringing the North closer to desiring an end to the war.

In January of 1973, the Selective Service announced the end to the draft and instituted an all-volunteer military. I was just beginning my submarine training at New London when the announcement was made. Since I had volunteered before I was eligible for the draft, it did not mean much to me personally. But I did notice that many who were serving around me had chosen a Navy path to avoid the Army. Some were upset that they had joined now that the draft was gone.

The rest of 1973 was spent shuttling around the country to various schools. From New London, I was sent to Charleston to learn advanced skills related to the boat I would eventually join in Guam. The USS George Washington had already left Charleston after a shipyard period so I would not see her until the fall of 1973 in Guam. The schools and a short stint TAD at the Submarine Base in Pearl seemed like an endless wait. I officially reported on board on August 28, 1973 to the Blue crew which was preparing to leave Hawaii. Then came the day I took my first crew flight from Hawaii to Guam.

Guam

Guam is a hot and humid place no matter what time of year you show up. The trip from Anderson Air Force Base was in a vintage non-air conditioned military bus. I remember pulling up to the USS Proteus and how tired we all were from the long flight and heat on the ground. We went on board the tender and were assigned to submarine crew quarters. The bunks were stacked on top of each other and the smell was horrible. The George Washington was not back from patrol yet (the Gold Crew had her) so we waited for a few days doing not much of anything.

I watched the boat as it came into the harbor. It seemed kind of small at first but by the time it was tied alongside you could see the top and sides. Men were scurrying with the lines and some hoses of one kind or another and there were thick black cable being connected between the boat and the Proteus. The Proteus was a leftover from World War 2 and the crew on board were stationed there all year round. We just came for visits twice a year and many of us were glad to leave her when the time came.

The smell

Once the boat was tied up, the turnover process began. As a young Fireman, I was not aware at the time of all the things that would need to be completed in order to successfully transition between Gold and Blue. I was just very anxious to get off the tender and into the boat. The very first time I went down the forward hatch I noticed a few things. The first is the smell. A submarine smell is something you never forget. It is a mixture of diesel, mono-ethylamine, cigarettes, cooking residue, body odors and many other things. It gets into your nose first then into your clothes. It never quite leaves you. If I close my eyes, I can still imagine what it smells like.

The good thing about being a new kid is that you don’t have much time to think. The work comes fast and furious and you do not want the Chief to catch you skylarking. There is just too much to do. The crew that is leaving is packing up their stuff as quickly as possible for the long ride home. Within a few hours, the on-loading process for the coming patrol begins. Boxes of food both frozen and canned are waiting to be loaded and the only way they get into the boat is through the long narrow hatches with men stationed on deck and all the way to the lowest levels of the boat. You load until everything is in the boat. Your arms are aching in a way that you never thought possible. Same with your back and legs.

As an Auxiliaryman, our job was to also make sure we had enough hydraulic oil and essential other fluids. These evolutions often happened at night sine they tied up the hatches. There was very little sleep. Broken equipment needed to be repaired, flex hoses needed to be changed out and a hundred little tasks that needed completed were rushed in order to make the deployment schedule. Topside, the deck gang went between chipping and p[painting and helping with weapons moves. The Russians were waiting for us just outside Apra Harbor and even though we were technically at peace, we were also technically at war. You made no assumptions.

The rain

Guam is in a tropical environment and when the rains come, they leave you soaked to the bone. No matter what is going on, the rains will not stop the progress. You simply went down into the boat soaking wet and tried your best to dry off before your next trip topside. After a while, you just gave up trying. And everybody got a cold within a week. The Doc would hand out Actifed like it was candy to keep people from getting too sick.

The first dive

At the end of the refit, things started to settle into a routine. The tanks were topped off, stores were loaded, the equipment that had been placed topside for repairs was all gone and the boat was ready for that first dive. I was in the control room standing messenger under instruction. That is about as low a position as you can find on a submarine. It means that you are an air consuming passenger without a real purpose in life. You really just did your best to stay out of everybody’s way as the boat approached the dive point. Strange new sights and sounds and a symphony of orders and replies fill the packed little space. Reports from all over the boat come rapidly in indicating that all spaces are prepared. The Officer of the Deck is the last man down and reports to the Conn.  The board goes straight and the order is given. Diving officer, submerge the ship.

The main vents are cycled open, you hear the rushing of the water and for just a moment, you pray to yourself. The boat takes a down angle, reports come in indicating a normal dive and then she settles out. The beginning of a very long ride begins. Mine took quite a few years to finish… It would end on the USS Ohio in another very rainy place called Kitsap County Washington.

You join a very selective community on that day.

For the rest of your life you will hear people ask what it was like and say things like, “Oh, I could never do that.” You just kind of smile and say to yourself that once upon a time, you thought so too. I kind of hope I make it another five years before I take my final dive. Old submariners will understand why.

“Brandywine, Brandywine this is Singing Bush. Gertrude Check.” 3

There should be no question in anyone’s mind that submarines are one of the most challenging duties any person could ever volunteer for. The men and now women who sail on these unique ships do so with the understanding that all care has been taken to provide for their safety but in the end, safety takes a place in line behind the word “mission”. I have spoken with combat veterans who faced live fire who told me that they could not see themselves serving on board one of these underwater craft. Yet year over year since 1900, American Bluejackets and Officers have raised their hands and taken an oath to defend the country while serving within the confines of a steel tube, closed on both ends, surrounded by the darkness of the world’s largest battlegrounds: the oceans.

When things go according to plan, the crew submerges the ship, conducts their business in silence and returns to some port with stories they are not permitted to tell. Like the contents of a black hole, you are aware that something happened there, but it is only for those who participate to understand the whole story. Some spend a few years in this life and some spend a career. All have a unique story and all have seen and done things that range from the tedious to the terrifying.

Sadly, some join a special group that is known to the submarine family as “On Eternal Patrol”. The unfortunate members who gain this status gain entry in ways that are the stuff of every submariner’s nightmares. Whether it was fire, flooding, loss of propulsion, an enemy attack, or any of a hundred things that went wrong, the boat often serves as a forever resting place for their physical remains. http://www.oneternalpatrol.com/uss-scorpion-589.htm

The Navy marks this day, May 22nd as the official loss date of the USS Scorpion. This is the official US Navy History of the USS Scorpion

“USS SCORPION was laid down on 20 August 1958 by the Electric Boat Division, General Dynamics Corp., Groton, Conn.; launched on 19 December 1959; sponsored by Mrs. Elizabeth S. Morrison; and commissioned on 29 July 1960, Comdr. Norman B. Bessac in command.

Assigned to Submarine Squadron 6, Division 62, SCORPION departed New London, Conn., on 24 August for a two-month deployment in European waters. During that period, she participated in exercises with units of the 6th Fleet and of other NATO navies. After returning to New England in late October, she trained along the eastern seaboard until May 1961, then crossed the Atlantic again for operations which took her into the summer. On 9 August, she returned to New London and, a month later, shifted to Norfolk, Va.

With Norfolk her home port for the remainder of her career, SCORPION specialized in the development of nuclear submarine warfare tactics. Varying her role from hunter to hunted, she participated in exercises which ranged along the Atlantic coast and in the Bermuda and Puerto Rican operating areas; then, from June 1963 to May 1964, she interrupted her operations for an overhaul at Charleston, S.C. Resuming duty off the eastern seaboard in late spring, she again interrupted that duty from 4 August to 8 October to make a transatlantic patrol. In the spring of 1965, she conducted a similar patrol.

During the late winter and early spring of 1966, and again in the fall, she was deployed for special operations. Following the completion of those assignments, her commanding officer received the Navy Commendation Medal for outstanding leadership, foresight, and professional skill. Other SCORPION officers and men were cited for meritorious achievement.

On 1 February 1967, SCORPION entered the Norfolk Naval Shipyard for another extended overhaul. In late October, she commenced refresher training and weapons system acceptance tests. Following type training out of Norfolk, she got underway on 15 February 1968 for a Mediterranean deployment. She operated with the 6th Fleet, into May, then headed west. On 21 May, she indicated her position to be about 50 miles south of the Azores. Six days later, she was reported overdue at Norfolk.

A search was initiated, but, on 5 June, SCORPION and her crew were declared “presumed lost.” Her name was struck from the Navy list on 30 June.

The search continued, however; and, at the end of October, the Navy’s oceanographic research ship, MIZAR (T-AGOR 11) located sections of SCORPION’s hull in more than 10,000 feet of water about 400 miles southwest of the Azores. Subsequently, the Court of Inquiry was reconvened and other vessels, including the submersible TRIESTE were dispatched to the scene, but, despite the myriad of data and pictures collected and studied, the cause of the loss remains a mystery.”

For an unusually long period, beginning shortly before midnight on 20 May and ending after midnight 21 May, Scorpion attempted to send radio traffic to Naval Station Rota, but was only able to reach a Navy communications station in Nea Makri, Greece, which forwarded Scorpion’s messages to ComSubLant. Lt. John Roberts was handed Commander Slattery’s last message, that he was closing on the Soviet submarine and research group, running at a steady 15 knots at 350 feet “to begin surveillance of the Soviets”. Six days later the media reported she was overdue at Norfolk.

The message read: “Brandywine, Brandywine this is Singing Bush. Gertrude Check.”

Over the years, many stories have emerged from people who were on active duty at that time that tell of a harrowing choice of alternatives to explain the “mystery”. I will wait to go on my own personal “Eternal Patrol” and try and find the crewmembers themselves to find the real answer. Until then , I just know they are gone. They are heroes in the sense that they gave their all for their country. For that reason, I salute their memory and pray for those who still traverse the oceans in these underwater vessels. May the number of dives and surfaces always be equal in the end.

A shipmate asked the other night about handling demons.

It’s a simple question that anyone who has been in a submerged submarine can understand. Years after you have left the boat, many still have dreams about what they did. The dreams can be so real sometimes. The feel of the boat sharply turning (even when you subconsciously know you are in your bed in the middle of the country). The claustrophobic surroundings of a dimly lit passageway surrounded by stainless steel covered bulkheads. The sound of the four hundred cycle hum and fan noises that suddenly go quiet. Periscope depth on a winter’s night in some remote sea lane surrounded by passing ships. A relief valve that lifts off its seat shouting its high pressure screams for all to hear.

And test depth.

The designed depth where the hull and all of the equipment are supposed to be able to operate with impunity to the dangers of the deep. Somewhere below, the real demon lives. Crush depth. Your training is filled with stories about the few boats that found where that monster waits to hold you in its death grasp. The sounds of the hull creaking and groaning under the pressure can be felt as you get closer to the test depth. The sound as you get closer to crush depth can only be heard in nightmares.

How do you handle the demons?

The answers are many and as diverse as the men and now women who ride submarines.

Some did their tours and went home in one piece. Some did careers and never look back at all. Others have not fared so well. Broken lives, divorces, substance abuse, isolation from others… all are part of a pattern repeated too many times. Maybe someday someone will be able to explain why some carry the demons with them and some bury them at sea.

Fifty years ago, a submarine named Scorpion was lost.

The legends and stories are many but I only think of the men who went with her to her grave. They were brave men who were performing a mission in defense of this country. They were all relatively young, many had families, and all had expectations of coming home. This crew and ship joined the ill-fated Gato Class submarine named Scorpion that was lost with all hands in 1944. They all gave their lives for our country.

See the source image

 

I am sure that for the next few decades after the second Scorpion was lost, many submariners would go to sea and think about the “What if?” She was a sturdy boat with a good crew. I know I did from time to time. It is easy to do when you know that the boat you are riding was the original Scorpion, repurposed to fulfill another mission. Although she was not lost, the boat she became tested her crew more than once in typhoons and a collision.

My demons? I write about them. Sometimes I go out and do presentations to civic groups and others that have a curiosity about the life. Alcohol never seemed to help. Took me a long time to figure that one out. Prayer works too but so many people put barriers between themselves and God, it is not something that should be taken lightly.

The demons we all faced are familiar to many who have never even submerged on a boat: they are the demons that remind us of our fragile and temporary existence. Accepting that truth is a pretty big step in keeping them in their place.

We will all pass through test depth on our way down one last time… until then, try to be a good shipmate and enjoy the ride.

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
Water is pumped out of the bottom pontoons and wingwall compartments to raise the ship out of the water.

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.

 

Picture:


Raising the Wingwalls of an Advance Base Sectional Dock with Hydraulic Jacks
Crews on top of wingwalls change position of the pins in the beams alternatively.

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.

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 2

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.

Post number 597… Submarine Number 597 6

An odd kind of submarine

USS Tullibee

USS Tullibee (This photo was probably taken shortly after her commissioning in 1960. The distinctive shark-fin domes are for the PUFFS sonar system).

 

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.
