Among her ports of call were Guantanamo Bay and Havana, Cuba, San Juan, Puerto Rico, Bridgetown, Barbados, Trinidad, Aruba, and Curaçao.

In April 1943, PC-568 reported to Commander, Eastern Sea Frontier, and began a series of convoy and antisubmarine patrols from New York City to Guantanamo Bay.

Upon her arrival the ship reported to Commander, United States Naval Forces Europe, and became a member of the 12th Fleet.

She visited Plymouth, England, Ponta del Gada, Azores, and Bermuda before arriving at Norfolk, Virginia, on 22 October.

Her name was struck from the Navy list on 15 March 1963, and the ship was transferred permanently to the custody of the United States Air Force.
