Bulwark (AMc-66) was laid down on 8 May 1941 at South Bristol, Maine, by the Bristol Yacht Building Co., renamed Avenge on 17 May 1941, launched on 14 February 1942 sponsored by Mrs. William A. Parker, and placed in service at Boston on 2 April 1942.
Following fitting out at Boston, Avenge sailed for Hampton Roads and arrived at Yorktown, Va., on 23 April for training at the Mine Warfare School. Upon completion of the training Avenge reported to the 6th Naval District, Charleston, S.C., for duty.
Avenge served at Charleston for the duration of her career. On 14 December 1945, the ship was placed out of service and laid up in the Wando River. Her name was struck from the Navy list on 8 January 1946, and the ship was turned over to the Maritime Commission for disposal on 8 August. She was subsequently sold to the United Fisheries Co., Gloucester, Mass.
