    The hull page lists 5 officers and 54 enlisted, troop accommodations for 2 officers and 46 enlisted, and two General Motors model 16-278A reversible diesel engines with hydraulic clutches, direct drive, 1,440 BHP each at 720 rpm, twin propellers, and 2,800 shp. It also lists two diesel-drive 100-kW AC generators and one diesel-drive 20-kW DC generator.

    Limitations
    Supports complement and diesel propulsion only. It does not identify asbestos-containing components or establish that any listed machinery insulation, gasket, packing, electrical insulation, or deck covering contained asbestos.

    Finding type
    asbestos_application
    Finding
    No ship-specific asbestos survey, product inventory, abatement record, or condition report was located. Because LSM-271 was a World War II U.S. Navy diesel landing ship, machinery or diesel-exhaust insulation, gaskets, packing, electrical insulation, and deck covering are possible class/era application categories, but none is documented aboard this hull.

    Possible categories only, not a finding that asbestos was installed aboard LSM-271. The cited hull page does not identify asbestos or insulation composition; no quantity, location, condition, exposure, or causation is established.

    Finding
    No ship-specific asbestos documentation was located in the public sources reviewed: the verified hull page and NVR resource contain no asbestos survey, insulation-material statement, abatement record, hazmat disclosure, or condition report for LSM-271.

    Limitations
    A negative public-source finding is not proof that asbestos was absent. Firecrawl was blocked and non-digitized Navy, shipyard, and wreck records may contain additional evidence; asbestos documentation therefore remains class_or_era.

    Finding
    The required authenticated CourtListener exact-name and hull-number searches were initiated through cl-auth-search.py, but the helper stopped when the fleet-wide pacing budget was spent. No litigation hit was returned or classified, and the sweep remains incomplete.

    This is an access-gap record, not a finding that litigation is absent. Because no results were returned, no hit can be classified as qualifying asbestos litigation, other litigation, or name collision; unsearched/unreturned records remain possible.
