- Finding
- Cross-check record: authorized as V-7 (SF-10), re-designated (SC-3); laid down as V-7 (SC-3) 14 June 1930 at Portsmouth Navy Yard, Kittery ME (USN photo caption: first rivet driven that date, Milne Collection/UNH); launched 6 Mar 1932; commissioned 1 July 1932 (conflicts with DANFS 1 June - variant in gaps); decommissioned 12 Oct 1945 at Portsmouth; struck from Naval Register 24 Oct 1945; sold for scrapping 26 Aug 1946; 2 battle stars. Spec block: displacement 1,560 surfaced / 2,215 submerged; length 319'1"; complement 5 officers 52 enlisted; diesel-electric propulsion - MAN diesels (hp 3500), Electro Dynamic motors (hp 1750), 240 battery cells, twin propellers. Photo caption (ca. 1943): little modified from peacetime appearance; after an inspection revealed considerable corrosion in her tanks she was sent back to New London for less demanding work.

[4]Era inference built on: DANFS/NavSource spec blocks (diesel-electric plant, no steam); shipyard-exposure-map documented asbestos product lists for Portsmouth Naval Shipyard (thermal insulation; asbestos cement; pipe covering; millboard; gaskets; seals; packing; block insulation; asbestos cloth; friction materials; Kaylo insulation) and Pearl Harbor Naval Shipyard (pipe covering; insulation blankets; cement compounds; gaskets; amosite blankets; asbestos mud; asbestos protective clothing; asbestos-containing wire insulation; asbestos cloth) [other_primary]

- Finding type
- asbestos_application
- Finding
- A diesel-electric submarine built 1930-32 at Portsmouth Navy Yard and refit/repaired at Pearl Harbor Navy Yard through WWII sits inside the Navy's asbestos era; era-standard asbestos applications for a boat WITHOUT a steam plant center on diesel exhaust/muffler lagging, gaskets, packing, and electrical/wire insulation rather than boiler-room insulation. Both yards' asbestos product use in the relevant period is independently documented at the yard level.

- Limitations
- Class/era inference only - no hull-specific insulation survey, material list, or work-package record located for SS-169. Names era-standard applications for a diesel submarine, not confirmed installed materials; no steam plant means no boiler-room framing applies. No quantity; nothing survives to sample (hull scrapped 1946).

- Finding type

- Finding
- GAO documented that the Navy used asbestos insulation extensively aboard ships and did not begin substituting alternative insulation materials until the early 1970s - encompassing Dolphin's entire existence (1930-32 construction, 1932-45 service, 1946 scrapping).

[6]Batch-99 search ledger (this record): DANFS transcription; CO Pearl Harbor action report transcription; NavSource cross-check; NVR check; LOC/HAER check; CourtListener API + web UI attempts; indirect web search for litigation naming the hull [other_primary]
- Locator
- search_ledger rows sl-uss-dolphin-ss169-01 through -09
- Finding type
- historical_record
- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or qualifying asbestos case naming USS Dolphin (SS-169) was found in accessible sources. CourtListener's v4 API returned HTTP 429 (125/day exhausted, ~34,211s backoff) and the public web UI returned an HTTP 202/403 challenge on 2026-09-18, so the vessel-name and hull-number litigation scan is INCOMPLETE - logged as blocked, not as zero hits. Indirect web search surfaced only law-firm marketing list pages naming the hull (mesotheliomasymptoms.com, mesolawcenter.com, mesothelioma.com, mesotheliomabook.com) - excluded per source rules; no qualifying result. HAER/LOC returned only name-collision records. NVR has no entry (ship disposed 1946, pre-dating register coverage).

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard, and the CourtListener throttle means litigation naming this hull cannot be ruled out - the scan is a blocked lead, not a completed negative. The hull was scrapped in 1946; no material condition can ever be documented from the extant record alone. Does not establish or defeat any claim of exposure or legal eligibility.
