USS Strength (AM-309) was a metal-hulled Admirable-class minesweeper built for the U.S. Navy during World War II.

She was laid down on 4 October 1943 by Associated Shipbuilders, Seattle, Washington; launched on 28 March 1944; sponsored by Mrs. H. W. McCurdy; and commissioned on 30 September 1944.

Strength was assigned to Mine Division 36 and began training with that unit at Lahaina Roads, Maui, rehearsing for the forthcoming invasion of Iwo Jima.

The ships remained there from 3 to 5 February before steaming for the Marianas where final staging for the assault on Iwo Jima was held.

She then assisted in clearing the approaches to the beaches off Okinawa for the impending assault on that island which began on 1 April.

One chose the minesweeper for its target, but her gunners set it afire, and it splashed several hundred yards astern.

She refueled at Ulithi, called at Pearl Harbor on 28 December 1945, and arrived at San Diego on 12 January 1946.
