Overhaul to 1 April 1946; joined JTF 1 for Operation Crossroads - departed SF 27 April, Bikini Atoll 22 May through the atomic tests, returned SF 8 September. Sailed 27 September 1946 for Tsingtao, China, station ship 14 October 1946 to 3 March 1947; SF 18 March 1947; out of commission in reserve 13 September 1947, San Francisco Reserve Group. On 25 August 1950, returning from sea trials prior to assignment to the Military Sea Transportation Service, collided with freighter Mary Luckenbach and sank off San Francisco. One battle star for WWII service.

- Museum account: Benevolence was one of three hospital ships in Tokyo Bay for the September 2, 1945 surrender (with USAHS Marigold and USS Rescue); she entered Tokyo Bay August 29, 1945 with Rescue and Tranquility and began processing liberated POWs within hours - among them Generals Wainwright and Percival and Medal of Honor recipients Richard O'Kane and 'Pappy' Boyington; then-Ens. Arlene Duerk (later first female admiral) served as a nurse on the first voyage. Conversion and outfitting detail: Todd Shipyard Brooklyn converted Marine Lion into 'a fully outfitted and air-conditioned floating hospital'; bed capacity 802; shipboard complement itemized as 58 officers, 30 nurses, 2 Red Cross workers, 24 chief petty officers, 230 crew, 238 hospital corpsmen; four operating rooms, dental clinic, physiotherapy and radiography rooms, neuropsychiatric unit, packed field hospital embarked.

- Design-level basis for era-consistent asbestos inference: the reproduced specifications list one GE combination HP/LP geared steam turbine; two Babcock & Wilcox header-type boilers (450 psi, 745 deg F); double Falk main reduction gear; six turbo-driven ship's service generators (three 500 kW 450 V DC, three 300 kW 120/240 V DC); single screw 9,000 shp - a fossil-fired steam plant of the type routinely insulated with asbestos-containing materials in this era. BUMED class material describes the six Haven-class hospital ships as 'completely air conditioned,' and the WWII Museum account confirms air conditioning 'throughout the hospital and crew's spaces' - a design feature whose period ductwork and insulation commonly used asbestos-containing products. Conversion-era work occurred at New York-area yards (this hull: Todd-Erie Basin, Brooklyn).

- NPS/NOAA wreck-site account for this hull: the hospital ship, converted from MC C-4 cargo vessel Marine Lion (Sun Shipbuilding, launched 10 July 1944; Todd-Erie Basin conversion; commissioned 12 May 1945), was removed from the reserve fleet in 1950 and refitted at Mare Island Naval Shipyard for Korean War service. On 25 August 1950, returning from test runs at 16-18 knots in fog, she was struck on the port side by freighter Mary Luckenbach and sank within ~40 minutes. The hull came to rest on its port side in 74 feet of water ~1 mile south of the main ship channel, 4,250 yards from Mile Rock bearing 252 deg true; 'the white hull with its red crosses was clearly visible at low water' and was deemed a hazard to navigation. 'Unable to raise the vessel, the wreck was dynamited in 1952 to clear the obstruction. More than 50 feet of water now covers the remains of Benevolence.' The report lists the site among 151 project-area shipwrecks assessed for the parks/sanctuary.

- Limitations
- NPS report states '18 people lost their lives' and '526 persons in all' aboard - both conflict with the dominant 23-dead / ~505-527-aboard figures (NavSource, contemporaneous press); the NPS figures appear erroneous and the discrepancy is carried in gaps rather than resolved. Demolition dated '1952' here vs. late-1951 explosive series in secondary accounts - conflict carried in gaps. The wreck was demolished and the site cleared to ~50 ft; the report notes significant intact structure is unlikely to survive. Contains no asbestos, materials, or condition-survey statements - documents the wreck site only.

- Finding
- Documented official proceedings from the 1950 loss - admiralty/disciplinary litigation, NOT asbestos litigation: (a) A Coast Guard marine-investigation board opened 1950-08-29; the freighter's mate testified Mary Luckenbach's radar was not working at collision; the government asked ~$14 million damages from Luckenbach Steamship Co. (b) The inquiry found both captains at fault for excessive speed in fog (SF Chronicle, 1951-03-29). (c) A Navy court of inquiry recommended a general court-martial for interim CO CAPT Barton E. Bacon Jr.; the GCM convicted him of hazarding a naval vessel with a gross-negligence specification (KWE account). (d) The USCG board moved to revoke freighter master Leonard C. Smith's licenses; Smith appealed and the revocation was reversed - USCG Appeal No. 586, Leonard C. Smith v. United States, 1952-11-28 (KWE-hosted document summary). (e) The MSTS harbor pilot who had the conn, Capt. Lyne G. Havens, died (apparent heart attack). Disposition of the government's damage claim is not located in public sources.

Law-firm vessel-list pages do enumerate AH-13 (mesobook, freeasbestostesting, simmonsfirm et al.) - boilerplate marketing, excluded as evidence.
