- Documented for this hull: 'LST-268 was laid down on 26 November 1942 at Ambridge, Pa., by the American Bridge Co.; launched on 18 June 1943; sponsored by Mrs. W. Ward Powell; and commissioned on 19 August 1943.' Asiatic-Pacific operations listed: occupation of Kwajalein and Majuro Atolls (February 1944); Tinian capture and occupation (July 1944); capture and occupation of southern Palau Islands (September and October 1944); Lingayen Gulf landing (January 1945); assault and occupation of Okinawa Gunto (March through June 1945). 'LST-268 was redesignated LSTH-268 on 15 September 1945'; occupation duty Far East until early February 1946; decommissioned 16 February 1946; struck 31 October 1947; sold 24 March 1948 to Consolidated Shipbuilding Corp., Morris Heights, N.Y., for scrapping. 'LSTH-268 earned five battle stars for World War II service as LST-268.'

Its scanned vessel status card records 'Name LST 268 ...

- asbestos_application
- Finding
- A diesel-powered LST-1-class ship built 1942-43 sits inside the Navy's documented asbestos-use era, but her plant carried NO boilers - the boiler/turbine steam-lagging pathway does not apply. Era-standard asbestos-relevant applications aboard a vessel of this type and period were diesel exhaust lagging and gaskets, machinery-space thermal and acoustic insulation, deck coverings, accommodation/bulkhead insulation, and winch/windlass brake linings. Her 1945 LST(H) hospital conversion would have added interior rework scope, but no work package, yard, or material record for that conversion was located.
