Service history

ARD-29 was placed in service at San Diego, California on 1 July 1944 and was employed by the Navy at the Naval Repair Base at San Diego during the latter part of 1944 and the beginning of 1945. Early in 1945, the drydock began to receive modifications at the Kaiser Cargo yard at Richmond, California, in preparation for assignment to advanced bases in the Pacific. She was placed in commission on 23 June 1945.

ARD-29 visited Everett, Washington, for about a month before getting underway for the Central Pacific on 22 July. She stopped en route at Kwajalein in the Marshall Islands to change tugs and then continued on to the Marianas on 24 August under tow by USS Wateree. The floating drydock arrived at Guam on 2 September and operated there and later at Okinawa until late in 1946 when she was transferred to Pearl Harbor. ARD-29 provided repair services to Pacific Fleet ships at Pearl Harbor until the beginning of 1959. At that time, she was towed back to Guam where she served out the last 12 years of her Navy career. During this assignment, she was named Arco on 28 March 1967. On 1 November 1971, Arco was loaned to the Imperial Iranian Navy. On 15 September 1976, her name was struck from the Navy list and she was sold to Iran on 1 March 1977. [1]

As of the end of 2007, she was still on the active list of the Iranian Navy as Drydock No. 400. [2]

USS <i>Artisan</i>

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.

<span class="mw-page-title-main">Service Squadron</span> Unit of the US Navy

A Service Squadron (ServRon) was a United States Navy squadron that supported fleet combat ships and US Navy Auxiliary ships. Service Squadrons were used by the US Navy from their inception in 1943 to as late as the early 1980s. At the time of their inception during the Second World War they allowed the US Navy to operate across the vast reaches of the Pacific Ocean for extended periods of time. Service Squadrons created temporary forward bases to allow the naval squadrons to spend less time in transit and more time in the area of combat. Ulithi, a small volcanic atoll in the central Pacific, is an example of a site converted for use as a forward base of supply. Service Squadrons essentially created a major naval base near the area of operation. With naval bases like, Naval Base Ulithi, to refit, repair and resupply, many ships were able to deploy and operate in the western Pacific for a year or more without returning to a major port facility. Among the vessels operating in service squadrons were tankers, Fleet oilers, refrigerator ships, ammunition ships, supply ships, floating docks and repair ships. They provided diesel, ordnance, aviation fuel, food stuffs and all other supplies. Equally important at places like Ulithi were the portable piers and floating dry docks which allowed many ships damaged by enemy action or Pacific storms to undergo repair without having to travel the thousands of miles back to a major US naval base. Ulithi was as far forward from the US naval base at San Francisco as the San Francisco base was from London, England. To have a fully functional major port in the middle of the Pacific was a significant aid to U.S. Navy operations.

<span class="mw-page-title-main">Auxiliary repair dock</span> Floating drydock

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.

<span class="mw-page-title-main">Auxiliary floating drydock</span> Type of United States Navy drydocks

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.
