Class Notes:
FY 1944. On 26 Feb 44 CNO directed the acquisition and conversion of these ships in response to a requisition (BAD 2671) for Heavy Duty Fleet Repair Ships submitted by the British on 31 Jan 44. The hull alterations and armament were to be based on the ARG type, and BuShips was then to install such repair ship facilities as could be accommodated. Liberty hulls already under construction for allocation to the U.K. were selected for the conversions. In a preliminary planning meeting on 3 February 1944, an effort was made to use the plans of TUTUILA (ARG-4), but it soon became apparent that the characteristics desired by the British differed in so many details that entirely new internal arrangement plans would be needed. Arguments over the alterations continued into June 1944, with the U.S. reportedly insisting on retaining some items that would make the ships suitable for U.S. use if they did not go to the U.K. Initially all five were to have been transferred to Britain under Lend Lease, and the British assigned names to all five, but the last three were reallocated to the USN on 23 Nov 44 before completion. AR-19, the only unit not converted at Baltimore, was modified at East Boston, Mass. where she was towed in late August 1944; her commissioning was delayed by the late delivery of a diesel generator auxiliary power switchboard.
