DANFS carries no Peruvian-phase detail beyond the 1951 purchase.

- Finding type
- asbestos_application
- Finding
- Era/design inference for this diesel-powered LST-1-class hull: no boilers aboard, so the steam-plant lagging pathway is absent; asbestos-relevant applications of the type are engine and exhaust lagging, machinery gaskets and packing, thermal and acoustic insulation in accommodation spaces, deck coverings/tile, and winch/crane brake linings. Documented mid-service alterations and a wartime dry-docking at builder-yard and repair facilities (Pendleton; Bethlehem Steel Pier 27; Pearl Harbor Navy Yard) are the maintenance-disturbance pathway for era-installed materials.

- Limitations
- Class/era inference only - no source located names asbestos aboard this hull; the BuShips design table does not itself state 'asbestos' content for any application. Establishes no quantity, no present-day presence, and no individual exposure. Yard availabilities are documented events; asbestos scope of the work is unestablished.

- Finding
- Yard-level documentation for this hull's builder site: the CMU brownfields study of the Ambridge industrial area (former American Bridge Company and neighboring steel-industry parcels, 39 acres) lists site contaminants as 'Oil, Asbestos, Debris, PCBs' and describes asbestos-containing materials, tar pits, painting facilities, and miscellaneous fill across the redevelopment area. The American Bridge Marine Department built LSTs at Ambridge during WWII; the yard closed in 1983.

- Post-industrial site-remediation documentation, not a wartime record - asbestos identified among brownfield contaminants does not by itself establish the 1943 shipbuilding material scope aboard any hull built there, and no hull is named. Documents the builder-site environment only; this vessel is not in the shipyards dataset (see gaps).

- Finding
- GAO reviewed the Navy's asbestos-exposure protection efforts (fieldwork at Long Beach and Norfolk Naval Shipyards): the Navy's 1975 policy removed asbestos insulation only when damaged or required for repairs; modified in 1979 to add selective replacement of asbestos insulation in high-maintenance areas. Program-level confirmation that asbestos insulation was installed in Navy ships and managed in place for decades.

CourtListener returned zero results for "LST-283" (opinions and dockets) and "LST 283" (opinions) on 2026-10-02.
