Rebecca Lukens was laid down on 7 January 1944, under a Maritime Commission (MARCOM) contract, MC hull 1551, by J.A. Jones Construction, Panama City, Florida; she was launched on 4 March 1944.^[9][1]

She was allocated to the Army Transport Service on 10 April 1944. She was converted at Point Clear, Alabama into an Aircraft Repair Unit (Floating) (ARU(F)) and designated USAAFS Rebecca Lukens (ARU(F)-2). The conversion added the shops to the Liberty ship, including machine, sheet metal, radiator, tank, wood, pattern, blue print, electrical, fabric and dope, paint, air-conditioned instrument and camera, radio, battery, propeller, tires and fuel cells, armament and turrets, plating, oxygen plant, radar, carburetor, and turbo-super-charger. Two LCVPs and two DUKWs were added for ship to shore transportation along with three or four Sikorsky R-4s helicopters.^[8]

The crew was given two weeks training in seamanship at the Grand Hotel in Point Clear, Alabama, on Mobile Bay. Classes included; swimming, elementary seamanship, life saving equipment, and advanced seamanship.^[8]

On 1 October 1944, Rebecca Lukens sailed from Brookley Field for the Pacific, commanded by Lieutenant Colonel William McCraw, USAAF. She first visited Guantanamo Bay, Cuba, to meet up with a convoy for Eniwetok.^[8]

On 19 November 1944, Rebecca Lukens arrived off Saipan, and began her mission of repairing the B-29s that were beginning their bombing missions of mainland Japan. Because the roads had not been finished yet her helicopters carried the parts to and from the ship to the air base. Rebecca Lukens was the sole supplier of breathing oxygen for the high altitude B-29s, she was averaging 100 cylinders of compressed breathable oxygen a day. On 6 December, her gunners shot down a Japanese Mitsubishi G4M "Betty" bomber. ^[8]

Rebecca Lukens set sail for Iwo Jima, on 16 April 1945. At the end of April Rebecca Lukens was renamed Major General Herbert A. Dargue. On 22 May 1945, she shot down another "Betty" with assistance from on shore anti-aircraft batteries.^[8]

Between November 1944 and 1 September 1945, Major General Herbert A. Dargue supplied B-29s and P-51s with over 38,000 parts and units, ranging from spark plugs to the central fire controls for the B-29.^[8]

On 2 March 1946, she was laid up in the National Defense Reserve Fleet, in the James River Group, in Lee Hall, Virginia. On 3 September 1970, she was sold for $41,330 to Horton Industry, Inc., for scrapping. She was removed from the fleet on 21 September 1970.^[10][11]
