- NavSource is a volunteer secondary compilation, not a primary registry - milestone dates generally track DANFS/NVR but its 7 July 1944 commissioning conflicts with DANFS's 4 July (see gaps). Contains no asbestos content; specifications are class-standard figures. Ribbon display omits the Navy Occupation Service Medal w/Asia clasp that secondary sources show - minor discrepancy unresolved.

- Finding
- Government-held imagery documents this hull at four points: fitting out at the builder's yard (1 July 1944), underway in the New York Channel (1 August 1944), on the Parang, Mindanao beachhead during the Southern Philippines consolidation (18 April 1945), and at anchor in San Francisco Bay postwar (c. 1945-46). These are physical-presence records - construction yard, deployment, combat area, and postwar return - and are the archival leads into NARA RG 19/80-G stills and Army film records for this hull.

- Finding type
- asbestos_application
- Finding
- A diesel-driven LST-542-class tank landing ship built in mid-1944 sits inside the Navy's documented asbestos-use era; era-standard applications aboard an amphibian of this type and period were thermal insulation and machinery/exhaust lagging in the engine room, gaskets and valve packing on machinery and piping, asbestos-containing deck coverings and tile, and accommodation insulation. As a diesel ship she carried no boilers or steam plant - the boiler/turbine lagging pathway of steam vessels does not apply, but the confined-space engine-room and interior-materials pathways do.

Names era-standard applications, not confirmed installed materials; no quantity; no manufacturer attribution for this hull. The Bethlehem yard product list is enterprise-level for Bethlehem Shipbuilding (Fore River/Sparrows Point/Union Iron Works aliases) and does not isolate the Hingham yard's materials.

[7]GAO, Navy Efforts To Protect Workers From Asbestos Exposure, HRD-80-2 (Oct 18, 1979) [gao]

- GAO product page HRD-80-2, Highlights section (live-verified 2026-10-03)
- Finding type
- gov_survey
- Finding
- GAO reviewed the Navy's efforts to protect workers from asbestos exposure at the Long Beach and Norfolk Naval Shipyards - specifically 'the use of asbestos in Navy ships, the cost of removing asbestos from Navy ships, and compensation programs for asbestos-related disabilities' - and documented that the Navy's 1975 policy removed/replaced asbestos insulation only where damaged or required for repairs, modified in 1979 to selective replacement in high-maintenance areas. This spans this hull's entire construction and service era (1944-46); the hull was scrapped before the substitution program existed.

- Finding
- Yard-level context for the builder: Bethlehem-Hingham Shipyard operated December 1941 through 1945 on 150 cleared acres at Hingham; more than 23,500 workers at peak (including 2,700+ women after the first year); produced roughly 227 ships - Evarts, Edsall, Cannon, and Buckley-class destroyer escorts plus LCI(L)s, LSTs, and APDs; set records of a destroyer escort in 23 days and five LSTs in 50 hours; received Army-Navy 'E' awards in consecutive years. A purpose-built mass-production yard of exactly the type this hull came off.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or verified litigation naming USS LST-927 was found in the public sources searched. CAVEAT: CourtListener could not be queried this session - the authenticated API returned daily-quota exhaustion (server-requested wait ~27,973 s / ~7.8 h); logged as blocked in search_ledger, not as a negative result. The secondary litigation sweep surfaced only law-firm marketing content (class-level 'LST 542' listicle pages and similar) asserting asbestos without primary sourcing - excluded by source policy. PubMed returned no Bethlehem-Hingham yard-specific asbestos cohort study.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - and the litigation repository search is a genuine open gap (throttled, not run). Hull scrapped 1947-48, so no museum-condition or modern-abatement evidentiary track exists; NARA deck logs, builder work packages, and any scrapping-contract records are undigitized leads. Does not establish or defeat any claim of exposure or legal eligibility.
