[2]NavSource Online, Submarine Chaser Photo Index, PC-461-class listing [other_primary]

- PC-461 Class Continued listing, entry 'PC-1085'
- Finding type
- vessel_history
- Finding
- The live NavSource PC/SC index lists PC-1085 in the PC-461 class of 173-foot steel submarine chasers. The index identifies the hull number and class, but does not provide a PC-1085-specific construction, service, crew, or disposition narrative.

- Study period
- 1943-1947 (hull period suggested by secondary leads; not established by this source)
- Limitations
- Index-level identity and class evidence only. It does not establish dates, builder, propulsion, crew, asbestos content, exposure, or final disposition. The exact PC-1085 detail page was not retrievable through the available direct fetch path and is not treated as verified here.

[3]National Archives, Special List 44, by Ship Numbers [other_primary]
- Locator
- Special List 44, by-ship-number finding aid; PC-series entries
- Finding type
- historical_record
- Finding
- NARA's Special List 44 is an official finding aid for Navy deck-log holdings by ship number and includes the PC series, including PC-461-class records. It provides an archival route for locating deck logs and related ship records, but the searched public finding-aid result did not yield a PC-1085-specific digitized log or history.

- Limitations
- Finding-aid evidence is not a ship-specific asbestos or exposure record. The absence of a located digitized PC-1085 file does not prove that no paper or microfilm record exists at NARA or NHHC.

[4]GAO, Navy Efforts To Protect Workers From Asbestos Exposure, HRD-80-2 (published 1979) [gao]
- Locator
- GAO HRD-80-2 product page, Highlights and Full Report description
- Finding type
- gov_survey
- Finding
- GAO reviewed Navy use of asbestos in ships and shipyard removal efforts. The report page states that the Navy used asbestos insulation aboard ships and that the 1975 policy removed or replaced insulation when damaged or when necessary for repairs, with a 1979 policy modification for high-maintenance areas.

- Population
- Navy shipyard workers and Navy vessels generally
- Limitations
- Program-level evidence only. GAO does not name PC-1085, identify its materials, quantify asbestos aboard this hull, establish an exposure event, or establish present-day material condition. Full report access was not used to infer hull-specific facts.

[5]Class/era inference based on the PC-461-class index and GAO Navy shipboard-insulation program record [other_primary]
- Locator
- NavSource PC-461-class index; GAO HRD-80-2
- Finding type
- asbestos_application
- Finding
- A steel PC-461-class submarine chaser built during World War II falls within the Navy's documented historical asbestos-insulation era. Possible era-standard applications include thermal insulation, pipe or machinery insulation, gaskets, packing, and electrical insulation; these are not confirmed aboard PC-1085.

- Study period
- World War II construction and service era
- Population
- World War II construction trades and Navy crew, not individually documented for this hull
- Limitations
- Inference only, never a ship-specific finding. No product, manufacturer, location, quantity, survey, or abatement action is attributed to this hull. The record therefore remains evidence tier 2 and does not claim that asbestos was documented aboard PC-1085.

[6]Authenticated CourtListener helper searches: exact 'USS PC-1085' and exact 'PC-1085' [other_primary]

- Finding type
- historical_record
- Finding
- No CourtListener search result was returned for the exact-name query 'USS PC-1085' or the exact hull-number query 'PC-1085'. No qualifying asbestos litigation, other litigation, or name-collision hit was identified in these authenticated searches.

- Limitations
- A no-result repository search is not proof that no litigation exists. The search covered the exact name and hull number required by the batch protocol; variants, unindexed documents, sealed records, and non-CourtListener material remain possible. No litigation-stage claim is made.

[7]Naval History and Heritage Command, Online DANFS index [nhhc_danfs]
- Locator
- NHHC Online DANFS index; PC-1085-specific entry not retrieved
- Finding type
- historical_record
- Finding
- The NHHC Online DANFS index was checked as the authoritative history route, but a retrievable PC-1085-specific DANFS entry was not located during this session. No ship-specific DANFS facts are asserted from the index page.
- Verification

- Limitations
- This is an access and retrieval gap, not evidence that DANFS contains no PC-1085 material. Candidate hull-history URLs were not treated as live evidence without a verified page. A future pass should search NHHC and its archival mirrors for the hull history.

- Finding type

- No ship-specific asbestos survey, abatement contract, hazmat disclosure, product inventory, environmental record, or authoritative litigation document naming PC-1085 was located in the sources searched. Asbestos documentation for this hull is unknown.

- Limitations
- This negative finding records the research boundary, not absence of asbestos. Firecrawl research was stopped after its keyless service reported a multi-hour quota wait; direct official-source checks continued. NARA/NHHC paper records, undigitized work packages, and unindexed court material remain open leads.
