- Robert Jacob construction workers; U.S. Navy crew and maintenance personnel, 1942-1948
- Limitations
- NavSource is a curated photographic-history archive rather than the Navy registry itself; the page is ship-specific and live-verified, but it does not state a commissioning or decommissioning date, does not provide asbestos information, and reports final fate as unknown.

- Program-level evidence, not evidence about YMS-360. It does not identify material installed aboard this hull, quantify asbestos, establish remaining material, or establish any person's exposure.

- Finding type
- asbestos_application
- Finding
- YMS-360 was a wooden YMS-1-class diesel minesweeper completed in 1943, inside the Navy's documented asbestos-use era. Era-standard applications may have included exhaust-system lagging, gaskets, valve packing, electrical insulation, or brake linings, but no such application is documented for this hull.

- Limitations

- CourtListener opinions and dockets indexed under the exact ship name or hull number
- Limitations
- A negative search result is not proof that no litigation exists. The four authenticated base queries were run once through the required helper on 2026-10-04; no asbestos-qualified variants were run because no base query overflowed its 20-result page. Name collisions and unrelated litigation were not treated as exposure evidence.
