    Finding
    DANFS entry for LST-497: laid down 26 August 1943 at Evansville, Ind., by the Missouri Valley Bridge & Iron Co.; launched 27 October 1943, sponsored by Mrs. Paul H. Schmidt; commissioned 31 December 1943, Lt. C. V. Riley, USNR, in command. Assigned to the European theater and participated in the invasion of Normandy in June 1944. Returned to the United States, decommissioned 18 December 1945, struck from the Navy list 8 January 1946, and sold 30 January 1948 to the Anglo-Canadian Pulp & Paper Mills, Quebec, Canada, for operation. Earned one battle star for World War II service.

    Limitations
    Archived copy used because the live NHHC page (https://www.history.navy.mil/research/histories/ship-histories/danfs/l/lst-497.html) returned 404 on 2026-10-02 - standing NHHC LST-port gap. Establishes identity and service history only; contains no asbestos, insulation, or material information. DANFS names Riley as commissioning commanding officer while NavSource's roster places Riley September-December 1945 and Steaken at commissioning - likely a DANFS transcription artifact, logged in gaps.

    Limitations
    Volunteer-compiled archive (reputable secondary). Two documented discrepancies: (1) commission date 23 Dec 1943 conflicts with DANFS and the BuShips SDB roster (31 Dec 1943) - NavSource's date may reflect a reduced-commission river transit to the New Orleans fitting-out yard, the pattern documented for sister LST-496, but that is unverified; (2) the 'MV Guy Bartholomew' merchant identity conflicts with registries documenting that name (IMO 5138656, later Fort Kent, foundered 7 Dec 1992 off Long Harbour, Newfoundland) as ex-LST-511 - treated as unresolved and probably erroneous cross-contamination. No asbestos information.

    Finding
    Era/design inference for the diesel-powered LST491-541 group: no boilers or steam plant, so the boiler/turbine lagging pathway is absent; asbestos-relevant applications typical of the type are GM diesel exhaust lagging and gaskets, engine-room thermal/acoustic insulation, deck coverings and tile, bulkhead and accommodation insulation, and winch/crane brake linings.

    Peer-reviewed historical study documents that asbestos was used extensively as a fireproofing and insulating material in U.S. shipbuilding during World War II - the era and emergency mass-production program under which this hull was built at an inland yard in 1943 - and that wartime demand drove unprecedented asbestos utilization aboard U.S.-built hulls.

    Finding
    An Orange County, Indiana veterans' honors-plaque transcription states that a sailor was 'assigned to the USS LST-497 at Plymouth, England. On 28 April 1944 during Exercise Tiger ... a German submarine torpedoed and sank the LST-497.' The sinking claim is false: the documented Exercise Tiger LST losses were LST-507 and LST-531 (with LST-289 damaged), and DANFS records LST-497 in continuous service through the June 1944 Normandy invasion to a December 1945 decommissioning. The plaque is useful only as an indication that LST-497 was in UK waters in spring 1944.

    Limitations
    Genealogy/memorial transcription, not an official record - cited to document and correct an erroneous claim that circulates on the open web (it conflates Exercise Tiger casualties with a hull that survived the war). The plaque's assignment detail (LST-497 at Plymouth, spring 1944) is consistent with the ship's documented European-theater assignment; its sinking claim is not.

    Limitations
    Absence of a located public record does not prove absence of asbestos aboard - a 1943 emergency-built diesel LST would be expected to carry era-standard asbestos applications even without a steam plant. Does not establish or defeat any exposure or eligibility claim. Deck logs and builder records at NARA are undigitized open leads.
