    A U.S. Senate tribute states that Andy Simkovitch of Erie, PA, 'was a U.S. Navy sailor that served aboard the tank landing ship USS L.S.T. 501 during World War II,' was 'involved in Operation Overlord at Utah and Omaha Beaches, where he transported troops during the D-Day landings on June 6, 1944,' and that 'during the operation and while under heavy German fire, he went to the beach nine times.' The tribute carries the ship's subsequent Pacific combat 'including the Battle of Okinawa' and Simkovitch's honorable discharge in March 1946. France awarded him the Chevalier Legion of Honor.

    asbestos_application
    Finding
    A diesel-powered tank landing ship built 1943 sits inside the Navy's documented asbestos-use era; era-standard applications aboard a ship of this type and period were GM diesel exhaust lagging and gaskets, engine-room thermal/acoustic insulation, deck coverings, bulkhead and accommodation insulation, and winch/crane brake linings. Her diesel plant means no boiler or steam-turbine lagging pathway - exposure relevance concentrates in machinery spaces, accommodation/deck materials, and ordnance/mooring equipment.

    No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or litigation naming USS LST-501 was found in the public sources searched (see search_ledger). CourtListener opinion index returned 0 results for all three name/hull variants; RECAP docket sweeps returned four name-collision dockets (Beck v. Warden; Curley v. Kerestes; Sofinet v. Truist Bank; Sills v. Garcia - habeas and civil matters where 'LST 501' appears as a form/document code), none vessel-related. One exact-phrase docket sweep ('USS LST-501', type=r) could not be completed - fleet pacing budget spent - logged as not completed, not a negative result. Secondary web sweeps surfaced no qualifying record; only marketing listicles assert asbestos aboard, excluded by source policy.

    Limitations
    Absence of a located public record does not prove absence of asbestos aboard - LST construction predates any documentation regime that would have disclosed materials publicly, and her 1948 scrapping predates ACM-handling regulation. The unrun exact-phrase docket sweep is an open procedural gap (pacing, not exhaustion). USNA action report and RG 24 deck logs are undigitized leads. Does not establish or defeat any claim of exposure or legal eligibility.

    historical_record
    Finding
    CORRECTION / unresolved-source-conflict flag: NavSource carries two 7 May 1948 disposition lines for this hull - a Maritime Commission transfer to COMNAVFE SCAJAP (redesignated Q097) and a sale for scrapping to Consolidated Builders, Seattle. DANFS and uboat.net support only the sale. The identical double-entry on sister LST-502's page (Q041, 20 May 1948) shows the pattern is systematic on NavSource - SCAJAP Q-numbers were assigned in the custody-transfer register even where the ship went straight to the scrapper. Separately, NavSource's Pacific organizational line (Flotilla 36 / Group 106 / Division 212) conflicts with the official 1 May 1945 fleet organization document (Flotilla 35 / Group 105 / Division 209) - the official document is carried; the NavSource line is flagged, not adopted.
