- Finding
- Documented for this hull (NHHC DANFS stub + NVR): contract awarded 15 July 1966 to General Dynamics Corp., Electric Boat Division, Groton; keel laid 20 September 1968; launched 1 May 1970 (sponsor Mrs. Earle G. Wheeler per secondary compilation); delivered 1 March 1971; commissioned 12 March 1971. DANFS records decommissioned and stricken 1 July 1999; recycling completed 21 April 2000. Secondary compilation (navysite) records assignment to Submarine Development Group Two, a Portsmouth Naval Shipyard overhaul January-December 1975, and participation in the 18 May 1987 three-submarine North Pole rendezvous - not independently verified.

[3]Era inference built on: NHHC DANFS/NVR record (S5W2 plant, single shaft); shipyard-exposure-map documented asbestos product lists for the associated yards; no hull-specific material record located [other_primary]

- Finding type
- asbestos_application
- Finding
- Era inference: a Sturgeon-class nuclear attack submarine built 1968-71 at Electric Boat, Groton, and maintained through Navy-yard availabilities including a documented Portsmouth overhaul sits inside the Navy's peak asbestos-use era. Era-standard applications on the secondary steam plant (steam generators feeding geared turbines) and auxiliary systems included thermal/pipe insulation, gaskets, packing, and machinery insulation. Documented asbestos product lines at the associated yards (Electric Boat/Groton, Portsmouth NSY) are recorded in the shipyard-exposure-map dataset.

- Population
- Shipyard construction trades (1968-71); yard availability trades; crew (1971-1999)
- Limitations
- CLASS/ERA INFERENCE ONLY - no ship-specific material schedule, insulation survey, or abatement record was located for this hull. Names era-standard applications on non-nuclear auxiliary systems; the S5W2 reactor plant itself establishes nothing. Does not establish asbestos aboard this hull, any exposure, or any quantity. Never infer ship-specific findings from this row.

- Finding type
- gov_survey
- Finding
- GAO documented that the Navy used asbestos insulation extensively aboard ships and did not begin substituting alternative insulation materials until the early 1970s - covering this hull's construction and the bulk of her service-era insulation events.

- synthesis of the ship's search-ledger rows
- Finding type
- historical_record
- Finding
- No qualifying ship-specific asbestos record located for USS Billfish (SSN-676): no asbestos survey, abatement contract, hazmat disclosure, or adjudicated exposure finding naming this hull was found. No qualifying litigation naming this hull was located in the retrieved RECAP corpus (Cooks, Halseth, Cronin, Siegfried, Gay, McIntyre, Speck, Harris checked by exact name and hull number).

- Population
- Shipyard construction trades; overhaul trades; crew
- Limitations
- Absence of a located public record does not prove absence of asbestos aboard or absence of exposure. Recycling-era hazmat/abatement records for the Ship-Submarine Recycling Program are not public. CourtListener live search was rate-limited/auth-walled during this batch (logged in the search ledger); coverage rests on the retrieved RECAP document corpus and prior-batch sweeps, which is not exhaustive. Does not establish or defeat any claim of exposure or legal eligibility.
