Equipped with the latest sonar gear, PCS-1386 was assigned to the Fleet Sound School Squadron following her shakedown period.

From her arrival at Key West, Florida, on 25 November 1944, until the end of World War II in August 1945, she trained officers and enlisted men in submarine detection, preparing the students to operate the range recorder and attack plotter during antisubmarine warfare operations by destroyers and destroyer escorts.

After World War II, PCS-1386 continued training operations based at Key West.

She also participated in naval exercises in the Atlantic Ocean, Caribbean Sea, and Gulf of Mexico between 1946 and 1956.

She operated as a training ship in a non-commissioned status until she was stricken from the Navy List on 1 July 1959 and sold.
