USSInterdictor (AGR/YAGR-13) was aGuardian-classradar picket ship, converted from aLiberty ship, acquired by theUS Navy in 1954. She was reconfigured as a radar picket ship and assigned to radar picket duty in the NorthPacific Ocean as part of theDistant Early Warning Line.
Interdictor (YAGR-13) was laid down on 18 May 1945, under aMaritime Commission (MARCOM) contract, MC hull 3142, as theLiberty shipEdwin H. Duff, byJ.A. Jones Construction,Panama City, Florida. She was launched 29 June 1945; sponsored by Mrs. Edwin S. Duff; and delivered 27 July 1945, to theMcCormack Steamship Co.[3][5]
She carried aircraft until entering theJames River Reserve Fleet,Lee Hall, Virginia, 17 October 1945. Except for brief cargo service, she remained there until being acquired by the US Navy, 10 May 1957.[5]
She was converted to aradar picket ship at theCharleston Navy Yard,Charleston, South Carolina, and commissionedInterdictor (YAGR-13), 7 April 1958.[3][5]
Fitted with the latest and best electronic search and tracking equipment,Interdictor sailed 2 May 1958, forshakedown training in theCaribbean. She departed Charleston, 18 July 1958, and sailed to her new home port,San Francisco, California.[5]
Arriving 13 August, the ship assumed her role as an ocean radar station ship, part of America's vast early warning defense system. Operating with search aircraft,Interdictor could detect, track, and report enemy aircraft at great distances, supplementing land-based radar stations, and controlling high-speed interceptor aircraft in case of attack. She also carried out weather reporting duties during her three to four week cruises in thePacific Ocean.[5]
Interdictor's hull classification was changed 28 September 1958, toAGR-13. She continued on radar picket patrols for theContinental Air Defense Command (CONAD) out of San Francisco, until decommissioned 5 August 1965.[5]
Her name was struck from theNavy Directory 1 September 1965, when she transferred to theUS Maritime Administration (MARAD) for lay-up in theSuisun Bay Reserve Fleet,Suisun Bay, California, where she remained until she was sold 13 June 1974. Her subsequent fate is not known.[3][5]
