    NavSource timeline for this hull: LSM-1 class Landing Ship Medium; laid down 29 September 1944 at Pullman Standard Car Manufacturing Company, Chicago, IL; launched 19 January 1945; commissioned USS LSM-343, 17 February 1945, LT Edward K. Schade USNR in command. During World War II assigned to the Asiatic-Pacific Theater: LSM Flotilla Fourteen, LSM Group Forty, LSM Division Seventy-Nine.

    Limitations
    NavSource is a volunteer secondary compilation, not a primary registry - its milestones generally track NVR/DANFS, but no DANFS entry exists for this unnamed hull and the stricken date is unknown. The history extract is a transcribed secondary account (Turner Publishing via the USS LSM/LSMR Association). Contains no asbestos or material content. Complement figure is from the class specifications block, unverified against DANFS/NHHC. The propulsion fit (Fairbanks Morse) is page-stated for this hull; class-level blocks on other LSM pages carry GM diesels - see gaps.

    Limitations
    Secondary enthusiast reference work, not a primary registry. The 'stricken 1974' fate reads as the Spanish Navy striking; NavSource's 9 April 1976 date is the scrapping sale - carried as a consistent sequence, not a conflict. Contains no asbestos or material content. Its technical-data block carries '4 General Motors diesels' for the class, which conflicts with the NavSource ship-page Fairbanks Morse fit - see gaps.

    Finding type
    asbestos_application
    Finding
    A diesel Landing Ship Medium built in 1944-45 sits squarely inside the Navy's documented asbestos-use era; era-standard applications aboard a 1944 diesel amphibious hull of this size were thermal insulation, machinery and diesel-exhaust lagging, gaskets, valve packing, and electrical insulation in machinery spaces. As a diesel hull she carried no boilers or steam plant - the boiler/turbine lagging pathway of steam vessels does not apply. Her builder (Pullman Standard) has no Atlas shipyard-dataset record, so no yard-level product list attaches - the inference rests on era alone, which is thinner than a yard-anchored record.

    Class/era inference only - no hull-specific insulation survey, material list, work package, or photograph of insulation was located for LSM-343. Names era-standard applications, not confirmed installed materials. No quantity. Product names are normalized era terms; no manufacturer attribution for this hull. Weaker than a yard-anchored inference: the builder has no Atlas yard record.

    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 entire U.S. Navy era (construction 1944-45, service 1945-46, reserve 1946-60).

    historical_record
    Finding
    Deck logs for USS LSM-343 (1945-46 commissioned service) are held by the National Archives (per NHHC, deck logs after 1940 are at NARA) but are NOT among the digitized deck logs in the National Archives Catalog: the full index page (8.5 MB fetched 2026-10-01) contains zero mentions of LSM-343. The digitized index skews to the Vietnam era (e.g., LSMR-409, 1965-70). The logs are the open archival lead for her 1945-46 movements and any recorded yard availabilities.

    Limitations
    Archival lead only: the digitized index was checked 2026-10-01 and LSM-343 is absent; the physical logs' existence at NARA follows from NHHC's general deck-log custody statement, not from a catalog entry verified for this hull. Deck logs in any case record movements and events, not materials - they are a lead for service history, not an asbestos source.

    Finding
    No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or litigation naming USS LSM-343 / LSM-343 was found in the public sources searched. CourtListener was searched this session via the authenticated fleet helper: 'USS LSM-343', 'LSM-343', and 'LSM 343' against opinions (type=o) - all three queries returned count 0 on 2026-10-01 (genuine negatives, HTTP 200). The matching docket queries (type=r) were not completed: the fleet-wide pacing limiter stood all three down (momentarily spent, ~114/hr shared budget), logged as pending rather than as negatives. Secondary web sweeps surfaced no qualifying case; the only 'asbestos aboard Navy ships' material is law-firm marketing content asserting asbestos across pre-1983 Navy ships without hull-specific primary sourcing - excluded by source policy.

    Limitations
    Absence of a located public record does not prove absence of asbestos aboard - it establishes only that no ship-specific public documentation was found. Deck logs, Pullman Standard work packages, and any Spanish disposal records are undigitized or unfetched leads. The docket side of CourtListener was not completed this session (fleet pacing stand-down, not a negative). Does not establish or defeat any claim of exposure or legal eligibility.
