An auxiliary floating drydock is a type of US Navy auxiliary floating dry dock. Floating dry docks are able to submerge underwater and to be placed under a ship in need of repair below the water line. Water is then pumped out of the floating dry dock, raising the ship out of the water. The ship becomes blocked on the deck of the floating dry dock for repair. Most floating dry docks have no engine and are towed by tugboats to their destinations. Floating dry docks come in different sizes to accommodate varying ship sizes, while large floating dry docks come in sections and can be combined to increase their size and lift power. Ballast pontoon tanks are flooded with water to submerge or pumped dry to raise the ship.[1][2]

## World War II

At the start of World War II, the US Navy had only three steel auxiliary floating dry docks:

1. Auxiliary floating drydock YFD-2, built in 1901, was at Pearl Harbor. YFD-2 was repairing the US destroyer USS Shaw on 7 December 1941 during the attack on the harbor. Both YFD-2 and USS Shaw were repaired, after being hit and damaged in the attack.[3]
2. The auxiliary floating drydock USS Dewey, built in 1905, was scuttled at Mariveles to prevent its capture by the Japan ese. In 1942 Japan raised the Dewey, but it was resunk by US forces.
3. Auxiliary floating dry dock USS ARD-1, built in 1933, was also at Pearl Harbor. USS ARD-1 was a self-sustaining mobile dry dock.

To reduce travel time for repair work, over 150 auxiliary floating dry docks of different sizes were built during World War II between 1942 and 1945. These newly built floating dry docks had a lift capacity of 400 to 100,000 tons. Without these forward repair bases, ships would have had to return to the US for repairs. Between 1 October 1944 and 17 October 1945, 7,000 ships were repaired in auxiliary floating dry docks. After World War II some auxiliary floating dry docks were sold for private use and others were scrapped. In addition to auxiliary floating dry docks, timber floating dry docks were built for use in World War II. Timber floating dry docks had a lift capacity of 400 to 20,000 tons. They were not towed across the open ocean and were not given a US Navy class.[4][2]

## Role

During wartime, ships in continuous use need repair both from wear and from war damage such as from naval mines, kamikaze attacks, dive bombs and torpedoes. Rudders and propellers are best serviced on dry docks. Without remote on-location dry docks, months could be lost if a ship returned to a home port for repair. Most auxiliary floating drydocks had provisions for the repair crew, including bunk beds, meals, and laundry. Most had power stations, ballast pumps, repair shops, machine shops, and mess halls to be self-sustaining. Some auxiliary floating drydocks also had provisions for the ship under repair, but when possible, the crew of the damaged ship remained on ship while repairs were done. Many had cranes able to lift tons of material and parts to remove damaged parts and to install new parts.[5][2]

## Armament

Most auxiliary floating drydocks had only anti-aircraft guns for defense, as space would not allow for large guns. Typical armaments included 40 mm and 20 mm machine guns. Japanese pilots sometimes mistook empty auxiliary floating drydocks for aircraft carriers.[6][2]

## Large Auxiliary Floating Dry Docks (AFDB)

USS AFDB-3 with rail traveling 15-ton crane

Auxiliary Floating Docks, Big (AFDB), also known as Advance Base Sectional Docks (ABSD), came in sections, 93 ft long and 3,850 tons each. Each section had a 165-ft beam, a 75-ft molded depth, and 10,000 tons of lifting capacity. Sections could be put together to lift larger ships. AFDB were needed to repair battleships, aircraft carriers, cruisers, and large auxiliary ships. The AFDB-1 Artisan had 10 sections (A to J) for a total lift of 100,000 tons, and was 1,000 ft long with all 10 sections installed. AFDB-1 to 7 were built between 1943 and 1945 and towed to remote navy bases. An AFDB would have a crew of 600 to 1,000 men, a fresh-water distilling plant and was otherwise self-sustaining. They had a rail traveling 15-ton capacity crane with an 85-foot radius and two or more support barges. To pump water from the tanks, there were two 24-in discharge pumps on each section, each pump rated 15,000 gpm. For electricity, there were two 350-kw diesel AC generators on each section, producing 440 volts 3-phase 60-cycle power. AFDBs had steam plants to run the pumps. Each section could store 65,000 gallons of fuel oil to supply the ships under repair. Crew lived in barracks ships, called APL, that docked next to the AFDB.[4][7][2][8]

AFDM are from 6,800 to 8,000 tons and are from 528 to 622 feet long. An AFDM has a crew of 140 to 200 men. An AFDM had a lift capacity 18,000 tons and was armed with two 40 mm and four 20 mm guns. It also had two ​7 1⁄2-ton cranes with 16 ballast tank compartments. AFDMs were built in three pieces, a long center section and two shorter sections, one at each end.[4][17][2][18] All AFDM also had Yard Floating Docks (YFD) class numbers.

## Yard Floating Dock (YFD)

YFD-2 The first Yard Floating Dock built in 1901, arriving Pearl Harbor 23 Oct. 1940 from New Orleans Naval Yard

Yard Floating Dock (YFD) was used for many types of floating docks, mostly used for harbor or shipyard use. YFDs normally had little-to-no crew space and were serviced from shore. Some auxiliary Repair Docks were converted to YFDs. Types of YFDs were: 400-ton concrete docks, 1,000-ton, 3,000-ton and 5,000-ton wood docks; sectional wood docks from 7,000 to 20,000 tons lifting capacity and a three-piece self docking steel sectional docks with 14,000 to 18,000 tons lifting capacity. All Medium Auxiliary Floating Dry Docks were converted to YFDs after World War II.[102][103][2]
