USS Interdictor (AGR-13)

USS **Interdictor** (AGR-13) was a Guardian-class radar picket ship of the United States Navy, originally built as the Liberty ship *Charles A. Draper* in 1944. Converted and commissioned in 1958, she served as part of the Continental Air Defense Command's seaward radar barrier during the Cold War, extending America's early warning network against potential Soviet air attacks. Operating primarily in the North Atlantic, Interdictor provided radar surveillance and communication relay services for approaching aircraft. She was decommissioned in 1965 as advances in radar technology and airborne early warning systems rendered her role obsolete.
