- Documented for this hull: 'laid down on 10 May 1943 at Seneca, Ill., by the Chicago Bridge & Iron Co.; launched on 21 September 1943; sponsored by Mrs. C. B. Hellerson; and commissioned on 16 October 1943.' Asiatic-Pacific operations: occupation of Kwajalein and Majuro Atolls (February 1944); Hollandia operation (April 1944); capture and occupation of Guam (July 1944); capture and occupation of southern Palau Islands (September-October 1944); Lingayen Gulf landing (January 1945); assault and occupation of Okinawa Gunto (April-May 1945). 'Following the war, LST-227 performed occupation duty in the Far East until mid-January 1946. She returned to the United States and was decommissioned on 22 January 1946. She served with the Shipping Control Authority, Japan, from 23 January 1946 to 6 June 1950. On 27 March 1955, she was transferred to Korea as a loan, where she served as Duk Bong (LST-808) into the mid 1970's. LST-227 earned six battle stars for World War II service.'

- Finding
- The landing order's task organization lists this hull in 'LST Unit ONE' (32.13.2, under Commander McFall) within the LST Flotilla under Captain Sampson: 'LST's 61, 243, 553, 127, 128, 224, 607, 227 (F).' The (F) flag notation on '227' is consistent with NavSource's record of LST-227 as the LST Group Thirty-Eight flagship, in the operation order context of the southern Palau Islands assault (Peleliu, September 1944).

Yard context: the Navy requisitioned the Seneca facility in 1942 and invested ~$6M; the 200-acre 'Prairie Shipyard' produced 157 LSTs and ARLs in 1942-45 and was sold to Union Mechling in 1949.

- Finding type
- asbestos_application
- Finding
- An LST-1-class hull built May-October 1943 sits inside the Navy's documented asbestos-insulation era. Diesel propulsion (2 x GM 12-567A, 900 hp each per BuShips SDB-1945 machinery data; no boilers) narrows the steam-plant lagging pathway; era-standard asbestos applications for a diesel LST of this period were engine-room thermal insulation, diesel-exhaust lagging, machinery gaskets and valve packing, deck coverings/tile and mastic, bulkhead and accommodation insulation, and winch/crane brake linings.

Names era-standard applications, not confirmed installed materials; no quantity; no manufacturer attribution for this hull.

[7]GAO, Navy Efforts To Protect Workers From Asbestos Exposure, HRD-80-2 (Oct 18, 1979) [gao]
- Locator
- GAO product page HRD-80-2 (full text blocked, HTTP 403)
- Finding type
- gov_survey
- Finding
- GAO documented that the Navy used asbestos insulation extensively aboard ships and did not begin substituting alternative insulation materials until the early 1970s - spanning this hull's construction (1943) and USN-era service. Standing Navy policy (1975) removed asbestos insulation only when damaged or required for repairs, modified 1979 to selective replacement in high-maintenance areas, meaning original-era insulation typically remained in place for decades unless a yard period disturbed it.

- Finding type
- historical_record
- Finding
- CORRECTION: the Wikipedia article's construction sentence says the ship was 'laid down on 10 May 1943 at Chicago Bridge and Iron Co., Quincy, Massachusetts' - a location error: the hull was built at CB&I's Seneca, Illinois 'Prairie Shipyard' per DANFS, NavSource, the builder table, and the class profile (the article's own infobox says Seneca). The article also carries 'Stricken: 28 April 1949' and 'struck from the Navy Register on 28 April 1949' - uncorroborated and conflicting with NavSource's 15 November 1974 strike date; DANFS gives no strike date. Korean-service details in the same article (commissioned 13 Sep 1955; decommissioned 31 Oct 1989; reclassified LST-672) are likewise uncorroborated.
