- Navy shipyard workers and Navy ships in the reviewed programs
- Limitations
- This is Navy-wide and shipyard-program context, not a finding about LST-827, its builder, its repair history, or its material inventory. It does not show which materials were installed aboard this ship or what remained at any point. Direct automated access to the cited GAO page returned 403; the indexed GAO product-page text was available through search.

- See search_ledger entries and batch report

- Population
- USS Hillsborough County (LST-827)
- Limitations
- A failed or incomplete search is not proof that no record exists. Firecrawl's MCP quota was exhausted with an approximately 14-hour reset; CourtListener's authenticated helper returned a 9.9-hour quota wait after the first exact-name opinion query, so no additional CourtListener queries were made. The litigation sweep is incomplete and this row is not a no-hit determination.
