Hospital ship USS Benevolence (AH-13)

USS Benevolence (AH-13) a United States Navy Hospital Ship, was built as SS Marine Lion in 1944 by Sun Shipbuilding & Drydock Co., in Chester, Pennsylvania, under a Maritime Commission contract. She was a C4-class ship, which were the largest cargo ships built by the United States Maritime Commission (MARCOM) during World War II. Among the variations of the design were the Haven-class hospital ship, including Benevolence and five others.

She displaced 11,141 tons fully loaded, was 160 m long, had a beam of 21.8 m and a draft 7.3 m. Her maximum speed was 17.5 knots. She was sponsored by Mrs. Daisy Unter, transferred to the United States Navy on 31 July 1944, converted to a hospital ship by Todd-Erie Basin Shipyard, Inc., Brooklyn and was commissioned on 12 May 1945.

On 25 August 1950 at 5:04 p.m. while returning from sea trials, prior to her assignment to the Military Sea Transportation Service in support of the Korean War effort, Benevolence collided with the freighter SS Mary Luckenbach in heavy fog and sank within 15 minutes off San Francisco. Five hundred and five crew members were rescued and 23 died.

The Defense Department announced on 31 July 1951 that the vessel was unsalvageable and would be dynamited as a menace to navigation.
