The ship was ordered on 25 January 1942 and laid down as the destroyer escort USS Lovering (DE-272), the first ship of the name, by the Boston Navy Yard in Boston, Massachusetts, on 20 May 1943. She was launched on 8 July 1943, sponsored by Mrs. Joseph S. Lovering, sister-in-law of the ship's namesake, the late Ensign William B. Lovering. The United States transferred the ship upon completion to the United Kingdom under Lend-Lease on 18 September 1943.
