The first Vigor (AMc-110)—a wooden-hulled, coastal minesweeper—was laid down on 6 August 1941 at Rock-land, Maine, by the Snow Shipyard, Inc.; launched on 19 January 1942; sponsored by Mrs. Lawrence Carver; and placed in service at the Boston Navy Yard on 4 May 1942.
Following fitting out, Vigor departed Boston on 6 May and headed for the Virginia capes. Proceeding via Tompkinsville, N.Y., the coastal minesweeper arrived at Yorktown, Va., on 20 May for training at the Mine Warfare School. Upon completion of her exercises in the Tidewater area, Vigor operated off the eastern seaboard between Newport, R.I., and Norfolk, Va.—with her home yard at New York—for the remainder of the Atlantic war. Sailing from Norfolk, bound for Charleston, S.C., the warship arrived at the latter port on 8 August 1945.
Subsequently placed out of service at Charleston on 31 October 1945 and laid up in reserve in the Wando River, Vigor was declared surplus and made available for disposal by the Maritime Commission's War Shipping Administration. Struck from the Navy list on 16 November 1945, the erstwhile minecraft was sold on 13 November 1946.
