    The USS SC-688, Coast Guard-manned, was accepted for the Navy from the Annapolis Yacht Yard, Annapolis, Md., on November 28, 1942. On December 4, 1942, she departed for Norfolk Navy Yard where she was outfitted for combat duty. She departed for New York on the 23rd and for Casco Bay, Maine, on the 26th.

On the 26th as the BIBB made a depth charge attack on a sound contact the sound apparatus of SC-688 gave no indication. On the 27th the radar was not working properly and on arrival at Argentia on the 29th repairs to radar and sound apparatus were undertaken. She relieved SC-706 on patrol of outer anchorage, Ship Harbor, Argentia from the 6th to the 8th of February, 1943, and then returned to port for further repairs to main generators. On the 22nd she departed for Burin Harbor, Newfoundland, towing the CG-147, accompanied by the CGC FAUNCE [WSC-138].
