- SC-685 paragraph
- Finding type
- vessel_history
- Finding
- DANFS records SC-685 as built at American Cruiser Co., Trenton, Michigan; keel laid 9 July 1942; launched 25 March 1943; commissioned 24 May 1943; and transferred to Russia on 19 July 1945.

- Study period

- Population
- American Cruiser Co. construction workers; U.S. Navy crew (1942-1945)
- Limitations
- Ship-specific milestone record. DANFS does not provide a complement, machinery specification, asbestos characterization, or litigation finding. It establishes U.S. Navy service before the Soviet transfer but does not by itself establish exposure or material content.

- Finding type
- vessel_history
- Finding
- NavSource identifies SC-685 as ex-PC-685, a SC-497-class submarine chaser laid down 9 July 1942, launched 25 March 1943, reclassified from PC-685 in April 1943, commissioned as USS SC-685, transferred to the Soviet Union 19 July 1945, and later designated BO-302. It lists a 148-ton displacement, 110-foot-10-inch length, 28-person complement, and two diesel engines on two shafts.

- Population
- U.S. and Soviet crews; construction and maintenance workers
- Limitations
- NavSource is a volunteer historical compilation, not an official Navy registry. It gives 25 May 1943 for commissioning, one day later than DANFS; the record uses DANFS's 24 May date and preserves the discrepancy in gaps. Its Soviet-service and specification details are not independently corroborated here. No asbestos content.

- SC-685 crew and shipboard workers during the listed logbook period
- Limitations
- This is a finding aid showing the date span of logbook holdings, not the contents of the logs. It corroborates the hull's documented U.S. Navy service period and identifies a primary archival lead; it does not identify asbestos, work performed, exposure, or causation.

- Population
- Navy shipyard and shipboard workers; program-level population
- Limitations
- Program-level Navy documentation from 1979; it does not name SC-685, PC-685, the American Cruiser yard, or any specific boat. It supports historical era context only and cannot establish that asbestos was installed on this hull, the quantity or condition of any material, or anyone's exposure.

- Finding type
- historical_record
- Finding
- NARA identifies ship engineering drawings, including S39 insulation and lagging and S48 piping records, as research leads for vessel-specific asbestos investigation, while cautioning that deck logs and muster rolls do not directly identify asbestos materials.

- Limitations
- Research guidance, not evidence that SC-685 contained asbestos. The specific SC-685 engineering drawings, inspection reports, and work packages were not retrieved in this review. The cited guidance supports an archival gap and next-step lead only.

[7]Batch 8059 research sweep: four authenticated CourtListener base searches plus official-source searches [other_primary]
- Locator
- search_ledger rows sl-uss-pc-685-pc685-01 through -08
- Finding type
- historical_record
- Finding
- No qualifying ship-specific asbestos litigation or public asbestos record was located for USS PC-685, PC-685, or SC-685 in the reviewed sources. The four required CourtListener base searches returned no hits: exact-name opinion, exact-name docket, hull-number opinion, and hull-number docket. No asbestos-qualified variants were run because no base query overflowed its 20-result page.

- Study period
- 2026-10-03
- Limitations
- A negative search result does not prove absence of asbestos aboard or defeat any exposure claim. The CourtListener result is limited to the four required base queries and public authenticated search results; it is not a finding that no unindexed or inaccessible docket exists. Firecrawl source access was unavailable because its keyless service reported a multi-hour quota wait; live official pages were checked through the available web fallback. No individual exposure, causation, legal eligibility, or material condition is established.
