The credited eligibility window (ending Feb 1946) is a medal-award record and does not itself prove where the ship was Feb 1946-Feb 1947; NavSource and DANFS place her on occupation duty through mid-February 1947.

- Finding
- The Dravo Pittsburgh build table lists 'LST 1055, U.S. Navy, Landing Ship, Tank, 1,625, 26-Apr-45, scrapped 1947' - recording a disposition (scrapping in 1947) that NavSource leaves as 'fate unknown.' The same page documents that Dravo's Neville Island yard (started 1919) was activated by the Navy in WWII specifically to build LSTs and was converted to a ship-scrapping facility after the war.

- Limitations
- A respected private shipbuilding compilation (Tim Colton's shipbuildinghistory dataset), not an official record - the 'scrapped 1947' disposition could not be corroborated against any primary source this session and conflicts with NavSource's 'fate unknown'; carried as an unresolved secondary-source claim (see gaps). Yard-history detail is contextual, not hull documentation. No asbestos content.

- Finding type
- asbestos_application
- Finding
- Era/design inference for a diesel-powered LST built in 1945: with no boiler plant, the steam-lagging pathway does not apply; asbestos-relevant applications for the type concentrated in diesel engine exhaust lagging and exhaust-system gaskets, engine-room thermal/acoustic insulation, deck coverings, bulkhead and accommodation insulation, machinery packing, and winch/windlass brake linings - the product families documented as asbestos-bearing in WWII-era naval and amphibious construction.

- Finding
- GAO documented that the Navy used asbestos insulation aboard ships and that its 1975 policy removed asbestos insulation only when damaged or required for repairs, modified 1979 to selective replacement in high-maintenance areas - program-level evidence that asbestos materials were endemic in the WWII-era fleet from which this hull came.
