The USS Benevolence (AH-13) was a United States Navy hospital ship constructed as SS Marine Lion in 1944 by Sun Shipbuilding & Drydock Co., located in Chester, Pennsylvania. As a C4-class vessel, she was among the largest cargo ships built under the Maritime Commission during World War II, displacing approximately 11,141 tons fully loaded. Her dimensions included a length of 520 feet, a beam of 71.6 feet, and a draft of 24 feet. Capable of reaching a maximum speed of 17.5 knots, the ship was designed for substantial operational capacity. Converted into a hospital ship by Todd-Erie Basin Shipyard, Inc., in Brooklyn, she was commissioned on 12 May 1945. The vessel had a bed capacity of 802 and a crew of 564. Shortly after commissioning, she departed for the Pacific theater on 27 July 1945, shortly before the end of World War II, to provide medical services, consultation, preventive medicine, and casualty evacuation. Her early service involved receiving battle casualties from the U.S. Third Fleet during campaigns against Japan. Notably, USS Benevolence was present in Tokyo Harbor at the time of Japan’s surrender and anchored off Yokosuka on 29 August 1945 to process liberated Allied prisoners of war, screening 1,520 POWs. She remained in Japanese waters until late November 1945, after which she returned wounded personnel to San Francisco on 12 December 1945. From December 1945 to February 1946, she served as a casualty evacuation ship between Pearl Harbor and San Francisco, followed by an overhaul. In June 1946, she participated in Operation Crossroads at Bikini Atoll, and from October 1946 to March 1947, served as a station hospital ship at Tsingtao, China. She returned to San Francisco in March 1947 and was placed out of commission in reserve on 13 September 1947. Her post-war career was cut short when, on 25 August 1950, she collided with the SS Mary Luckenbach in heavy fog while returning from sea trials off San Francisco, sinking within 15 minutes. Despite rescuing 505 crew members, 23 lives were lost. The vessel was declared unsalvageable and was subsequently destroyed as a navigation hazard.
