USS Tracer (AGR-15)

USS Tracer (AGR-15) – also known as USS Interrupter (AGR-15) – was a Guardian-class radar picket ship acquired by the U.S. Navy in 1957 from the "mothballed" reserve fleet. She was reconfigured as a radar picket ship and assigned to radar picket duty in the North Pacific Ocean as part of the Distant Early Warning Line.

Because of the closeness of the sound of names issued for radar picket ships at the time, Interrupter had her name changed by the Navy to Tracer so as not to confuse her with USS Interdictor (AGR-13) and USS Interpreter (AGR-14)
