ABSD-6 is an advanced base sectional dock which was constructed of nine advance base docks (ABD) sections for the US Navy as an auxiliary floating drydock for World War II. ABSD-6 was built by Mare Island Naval Shipyard at Vallejo, California. ABSD-6 was commissioned on 28 September 1944. Advance Base Sectional Dock-6 (Auxiliary Floating Dock Big-6) was constructed in sections during 1942 and 1943. Each section are 3,850 tons and are 93 feet long each. Each Section had a 165 feet beam, a 75 feet molded depth and had 10,000 tons lifting capacity each. There were 4 ballast compartments in each section. With all nine sections joined, she was 825 feet long, 28 feet tall (keel to welldeck), and with an inside clear width of 133 feet 7 inches. ABSD-2 had a traveling 15-ton capacity crane with an 85-foot radius and two or more support barges. The two side walls were folded down under tow to reduce wind resistance and lower the center of gravity. ABSD-6 had 6 capstans for pulling, each rated at 24,000 lbf (110,000 N) at 30 ft/min (0.15 m/s), 4 of the capstans were reversible.[1][2][3][4][5]
World War II[edit]
Commissioned as USS ABSD-6 on 28 September 1944, ABSD-6 was assigned to the Asiatic-Pacific Theater. ABSD-6 was towed in sections to the Naval Base Guam at Apra Harbor in Guam, Marianas Islands. After assembling she was placed in service to repair ships at Guam with her sister ship USS ABSD-3. On an island in the harbor at Guam the Navy built a base to support the crew of ABSD-6 and ABSD-3. At the base were supplies, movie theater, mess hall, Officers Clubs, movie theater, and Enlisted club and more. The base was built mostly with quonset huts. The largest repairs at Guam was that of the battleship USS South Dakota (BB-57) in May 1945. South Dakota was in need of drydock repairs after an accidental explosion on 6 May 1945 while South Dakota was rearming from USS Wrangell. South Dakota was at Guam with ABSD-6 from 11 to 29 May 1945. Due to South Dakota's 36.3 ft (11.1 m) draft with a full load, the battleship had to unload much of her ammunition and fuel oil before entering AFDB-6. Another large ship repaired and painted was USS Makin Island, a 7,800-ton Casablanca-class escort carrier. Able to lift 90,000 tons ABSD-6 could raise large ships like, aircraft carriers, battleships, cruisers, and large auxiliary ships, out the water for repair below the ship's waterline. She was also used to repair multiple smaller ships at the same time. Ships in continuous use during war need repair both from wear and from war damage from naval mine and torpedoes. Rudders and propellers are best serviced on dry docks. Without ABSD-6 and her sister ships, at remote locations months could be lost in a ships returning to a home port for repair. ABSD-6 had power stations, ballast pumps, repair shops, machine shops, and could be self-sustaining. ABSD-6 had two rail track moveable cranes able to lift tons of material and parts for removing damage parts and install new parts. Some of the ships repaired by ABSD-6 at Guam:

Post war[edit]
ABSD-6 was decommissioned on 29 June 1946 and laid up in the US Navy Reserve Fleet. ABSD-6 was re-designated Large Auxiliary Floating Dry Dock AFDB-6. AFDB-6 was sold for scrap on 1 January 1976 by the Defense Reutilization and Marketing Service.[9] [2][4]
