- Finding type
- vessel_history
- Finding
- NavSource's PC-475 hull page identifies this vessel as a PC-461-class submarine chaser. It states that Defoe Shipbuilding Co., Bay City, Michigan laid her down on 11 September 1941; launched her on 16 December 1941; commissioned USS PC-475 on 27 December 1941; assigned her to the European theater during World War II; and decommissioned and transferred her to France at Casablanca on 23 June 1944 as Le Resolu (W 33). The page states that the French vessel was decommissioned on 6 January 1951 and that the ultimate fate is unknown.

- Limitations
- NavSource is a naval-history compilation rather than a Navy engineering or asbestos record. It does not establish asbestos presence, product identity, exposure, causation, legal eligibility, or the vessel's final disposition beyond 'fate unknown.' No DANFS history is available on the page.

[3]National Archives and Records Administration, Special List 44, by Ship Numbers, PC-475 entry [other_primary]

- Finding type
- historical_record
- Finding
- NARA's Special List 44 identifies PC-475 in the Navy deck-log finding aid with coverage from 7 February 1942 through 22 June 1944. This is a ship-specific archival lead covering the vessel's U.S. Navy service period.

- Limitations
- The finding aid establishes record coverage, not the contents of any deck log. The underlying logs were not retrieved and the entry does not establish asbestos, a repair event, an individual exposure, or legal eligibility.

[4]NAVSEA Standard Item 009-10, Shipboard Asbestos-Containing Material (ACM); control, FY-16 package [other_primary]
- Locator
- Item 009-10, sections 1.1 and 3.1
- Finding type
- asbestos_application
- Finding
- Navy asbestos-control guidance identifies shipboard insulation, lagging, deck tile, underlayment, gaskets, cabling, and mastic as materials that may require asbestos controls unless reliable documentation or laboratory analysis establishes otherwise. This is general Navy policy context relevant to research on a World War II-era ship, not a finding that any listed product was installed aboard PC-475.

- Limitations
- The 2014 Navy standard is not a PC-475 construction specification, survey, or abatement record and post-dates the vessel. It cannot prove that PC-475 contained asbestos, identify quantities or locations, or establish any person's exposure.

[5]National Archives and Records Administration, Researching Asbestos aboard US Naval Vessel up through 1961 [other_primary]
- Locator
- Beginning Research; Cartographic Branch; RG 19 ship engineering drawings and General Information Books sections
- Finding type
- historical_record
- Finding
- NARA's research guide for asbestos aboard U.S. naval vessels through 1961 directs researchers to ship engineering drawings, including S39 insulation and lagging and S48 piping, while expressly warning that the identified record series do not by themselves provide direct evidence of asbestos. The guide identifies ship-specific drawings and General Information Books as archival leads for a vessel such as PC-475.

- Researchers and Navy-vessel personnel records
- Limitations
- This is research guidance, not a PC-475 record. The referenced drawings and books were not retrieved in this batch, so this row establishes only an archival path and does not establish asbestos presence or exposure aboard the hull.

[6]CourtListener authenticated helper, required four-query sweep (exact-name opinion attempted; exact-name docket and hull-number opinion/docket blocked by fleet pacing budget) [court_record]
- Locator
- Authenticated helper invocation on 2026-10-03; no result body was returned before stand-down
- Finding type
- litigation_documented
- Finding
- No qualifying ship-specific asbestos litigation finding was established in this batch. The required authenticated CourtListener sweep was stopped after the first base-query attempt because the fleet pacing limiter reported that the shared request budget was spent; the remaining base queries were not treated as no-result findings.

- Limitations
- This is an incomplete search-status finding, not a negative litigation result. No asbestos-qualified variants were run. The record does not establish whether any complaint, docket, opinion, or adjudicated exposure evidence exists for PC-475.
