    vessel_history
    Finding
    NavSource's ship-specific history identifies LSM-250 as an LSM-1-class landing ship medium laid down 23 August 1944 at Western Pipe and Steel Company, San Pedro, California; launched 15 October 1944; commissioned USS LSM-250 on 7 December 1944; assigned to LSM Flotilla Nine, LSM Group Twenty-Six, and LSM Division Fifty-Two; decommissioned 1 June 1949 at San Diego; laid up in the Pacific Reserve Fleet; sold in July 1958 to Pacific Towboat & Salvage Co. in Long Beach and converted to a barge, with fate unknown. The page also lists a 1944-1949 commanding-officer roster.

    Limitations
    The page contains an apparent copy error identifying another LSM hull before its occupation/China dates; those dates are not attributed to LSM-250 here. The page does not document asbestos, materials, exposure, or causation. Final post-conversion fate is unknown.

    Finding
    The NavSource ship page records ship-specific specifications: 520 tons light, 743 tons landing, 1,095 tons fully loaded; 203 feet 6 inches overall; 34 feet 6 inches beam; 13.2-knot maximum speed; 5 officers and 54 enlisted; capacity for five medium or three heavy tanks, six LVTs, or nine DUKWs; and two General Motors GM 16-278A diesel engines with twin propellers and 2,800 shp total. The page links a USS LSM-250 deck log covering 7 December 1944 through 13 January 1945 and an air/sea rescue report dated 14 August 1945.

    Specifications: Propulsion and Ship's Service Generators
    Finding type
    asbestos_application
    Finding
    The ship-specific specification block documents diesel propulsion rather than steam boilers or steam turbines. Accordingly, no boiler or turbine lagging claim is made for this vessel. The available source does not identify any asbestos-containing component, product, location, quantity, or condition aboard LSM-250.

    Limitations
    Diesel propulsion is a ship-specific technical fact, but the asbestos conclusion is negative: the source does not document asbestos. This row must not be read as proof that asbestos was absent or present, and it does not establish exposure, causation, or legal eligibility.

    historical_record
    Finding
    No qualifying ship-specific asbestos record was located in the public sources searched: no asbestos survey, abatement contract, hazmat disclosure, asbestos product identification, or qualifying litigation record naming USS LSM-250 was found. The NavSource ship history and linked-resource descriptions contain no asbestos statement.

    Limitations
    This is a negative public-record finding, not proof that asbestos was absent. The CourtListener sweep was interrupted by the fleet pacing limiter after the exact-name opinion request; the exact-name docket and hull-number requests remain a gap. The finding does not establish or defeat exposure, causation, or legal eligibility.

    Repositories and Research sections: 1941-1983 unclassified deck logs at NARA
    Finding type
    historical_record
    Finding
    NHHC states that unclassified Navy deck logs from 1941-1983 are held by the National Archives and Records Administration, and explains that deck logs are permanent records transferred to NARA. This provides an archival path for the linked LSM-250 deck log and other ship records, but no NARA accession or asbestos-specific document for LSM-250 was located in this batch.

    This is repository guidance, not a located LSM-250 record and not an asbestos finding. A targeted NARA retrieval was not completed; whether the linked deck log contains any material or repair detail is unknown.
