ww2dbaseFloating drydock USS ABSD-2 was a non-powered naval vessel designed to be able to deployed, with relative speed, to combat zones for ship repair operations, thus saving the time necessary to transport a damaged ship back to the continental United States. She was built in ten separate sections in United States between 1943 and 1944 by various shipyards in the United States, including the Mare Island Naval Shipyard in Vallejo, California, United States. Joseph Rochefort was the chief equipping officer of ABSD-2; although originally slated to command the floating drydock after commissioning, Rochefort would later be transferred elsewhere in the US Navy. Upon commissioning, USS ABSD-2 departed for Manus, Admiralty Islands in sections, under tow, in May 1944, and by Sep 1944 they were assembled and were ready for operation. After the war, she was redesignated AFDB-2 in Aug 1946. Five of her sections, A, B, C, E, F, G, and I were disposed of in various manners in 1990. At the time of this writing, three of her sections, F, D, and H, are still in service.

I am working on a book about theABSDs. Do you have contacts for family members of the C.O., such as CDR Andrew Mack, and Captain Joe Rochefort. I live in Portland, and can see section 1-D still afloat in Swan Island lagoon. Vigor shipbuilding still uses four sections of AFDB-1.Cheers, J.
