A dry dock is a narrow basin or vessel that can be flooded to allow a load to be floated in, then drained to allow that load to come to rest on a dry platform. Dry docks are used for the construction, maintenance, and repair of ships, boats, and other watercraft.
USS Alexander Hamilton (SSBN-617) was a United States Lafayette-class ballistic missile submarine. It was the third ship of the United States Navy to be named for Alexander Hamilton, the first US Secretary of the Treasury, who was instrumental in the formation of both the United States Coast Guard and the United States Navy.
USS Whale (SSN-638) was a Sturgeon-class submarine nuclear-powered attack submarine of the United States Navy. She was the second ship of that name, after the whale family of aquatic mammals.
USS Pargo (SSN-650), a Sturgeon-class attack submarine, was the second ship of the United States Navy to be named for the pargo, also known as the red snapper, a fish of the genus Lutjanus found in the West Indies.
USS Springfield (SSN-761), a Los Angeles-class submarine, is the fourth ship of the United States Navy to bear the name. The boat was named in honor of both the cities of Springfield, Illinois and Springfield, Massachusetts.
USS Oak Ridge (ARD-19/ARDM-1) was originally a United States Navy Auxiliary floating drydock suitable for dry docking destroyers, submarines and landing craft, built by the Pacific Bridge Company. In the early 1960s she was upgraded to support Los Angeles-class submarines, and re-classified as ARDM-1-class. A stern door and enclosed bow design allows for open ocean transits. The dock is non-propelled and therefore must be taken under tow to operational areas of the fleet. A steering mechanism with twin rudders is installed to facilitate this operation. Sufficient electrical power was provided by four diesel-driven generator sets to maintain all normal and operational requirements. Living, berthing, and mess facilities are provided for the dock's complement of 5 officers, 10 CPO's and a crew of 186.
USS Artisan (ABSD-1), later redesignated as (AFDB-1), was a ten-section, non-self-propelled, large auxiliary floating drydock of the United States Navy. The only U.S. warship with this name, Artisan was constructed in sections during 1942 and 1943 by the Everett-Pacific Shipbuilding & Dry Dock Company, in Everett, Washington; the Chicago Bridge & Iron Company, in Eureka, California; the Pollock-Stockton Shipbuilding Company, in Stockton, California; and the Chicago Bridge & Iron Company, in Morgan City, Louisiana. This ship was commissioned at Everett, Washington, on 10 May 1943, Captain Andrew R. Mack in command. With all ten sections joined, she was 927 feet long, 28 feet tall, and with an inside clear width of 133 feet 7 inches.
An Auxiliary repair dock (ARD) is a type of floating drydock employed by the U.S. Navy, especially during World War II. The Navy commissioned 33 ARD vessels: ARD-1 through ARD-33. ARDs were self-sustaining in World War II. ARDs have a rudder to help in tow moving, making ARDs very mobile, and have a bow to cut through waves. ARDs have a stern that can be opened or closed. The stern can be closed with bottom-hinged flap gate, operated by hydraulic rams. This stern gate can be lowered for ship entrance into the submerged dock, and then closed to keep out waves. ARDs were built by the Pacific Bridge Company, in Alameda, California.
USS Richland (YFD-64/AFDM-8) was an AFDM-3-class medium auxiliary floating drydock built in California for the U.S. Navy. Originally named USS YFD-64, she was towed to the Philippines and Guam where she served until war's end.
Arco (ARDM-5) is an ARDM-5-class Medium Auxiliary floating drydock for repair and serviced the United States Navy.
Alamogordo (ARDM-2) — a non-self-propelled United States Navy Auxiliary floating drydock completed in 1944 at Oakland, California, by the Pacific Bridge Company as ARD-26 — was commissioned on 15 June 1944, Lieutenant Commander Irving B. Smith, USN (Ret.), in command. The floating dry dock completed outfitting at Oakland and training at Tiburon, CA, between mid-June and late August. On 3 September, she was taken in tow for the voyage west. En route to the Marianas, the dry dock made layovers of ten and seven days respectively at Pearl Harbor and Eniwetok. She arrived at Guam on 24 October and reported for duty with Service Squadron 11 (ServRon 11). Not long thereafter, however, she was assigned temporarily to ServRon 10.
USS Endurance (ARDM-3) was originally laid down as ARD-18, a non self-propelled United States Navy Auxiliary floating drydock in 1944. Built by the Pacific Bridge Company in Alameda, California. During World War II USS ARD-18 was assigned to the Asiatic-Pacific Theater and serviced ships at Guadalcanal and Ulithi. After the war, floating dry dock ARD-18 was sent to Norfolk Shipbuilding and Drydock Corp.'s yard, circa 1967-68 and was lengthened by adding a 100 ft (30 m) midsection as well as an additional deck above the uppermost crane deck. Redesignated Medium Auxiliary Repair Dry Dock Endurance (ARDM-3), she served until retirement in 1995.
USS Waterford (ARD-5) was an Auxiliary floating drydock that served in the United States Navy during World War II, the Korean War, the Vietnam War, and the Persian Gulf War. She later served the Chilean Navy as Talcahuano (133).
An auxiliary floating drydock is a type of US Navy 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.
USS AFDM-2 (YFD-4) is an AFDM-3-class medium auxiliary floating drydock built in Mobile, Alabama by the Alabama Drydock and Shipbuilding Company for the U.S. Navy. Originally named USS YFD-4, Yard Floating Dock-4, she operated by Todd Shipyards at New Orleans, Louisiana for the repair of US ships during World War II. YFD-4 was renamed an Auxiliary Floating Dock Medium AFDM-2 in 1945 after the war. USS AFDM-2 was 37 feet (11.3 m) tall, 116 feet (35.4 m) wide, length of 614 feet (187.1 m), and has a displacement of 6,360 tons. AFDM-2 could lift capacity 9,000 tons and had two service cranes to lift material and parts for removing damage parts and the installation of new parts. The floating drydock can repair ships up to a beam of 90 feet (27.4 m), as she is 90 feet wide between the wing walls. Ballast pontoons tanks are flooded with water to submerge or pumped dry to raise the ship. Submerged she can load a ship with a draft up to 20 feet (6.1 m).
USS ABSD-2, later redesignated as AFDB-2, was a ten-section, non-self-propelled, large auxiliary floating drydock of the US Navy. Advance Base Sectional Dock-2 was constructed in sections during 1942 and 1943 by the Mare Island Naval Shipyard in Vallejo, California for World War II.
