- Limitations
- Ship-specific history only; no asbestos or material content. Critically, DANFS documents a ~2.4-year Mare Island overhaul-and-refueling period September 1987-February 1990 - yard presence is documented, material disturbance is not.

[3]Cooks v. General Electric Company, No. 3:07-cv-05451-EMC (N.D. Cal.), complaint Exhibit A work-history/exposure exhibit, ECF No. 1-2 (filed 2007-10-25) [court_record]
- Locator
- ECF 1-2, Exhibit A vessel list and job-duties block (Mare Island Naval Shipyard, Vallejo)
- Finding type
- litigation_documented
- Finding
- Asbestos complaint exhibit (plaintiff Alvin Cooks's Mare Island Naval Shipyard work-history/exposure exhibit, Marine Machinist 1974-1995) lists vessels and locations of alleged asbestos exposure, expressly including 'CAVALLA (SSN-684)'. The exhibit describes machinist duties including removing and replacing gaskets and packing, cutting gaskets, and cleaning valves, pumps, and blowers around insulators and other trades.

- Population
- Mare Island Naval Shipyard trades (plaintiff's claimed window)
- Limitations
- Complaint-exhibit vessel list; unadjudicated pleading-stage allegation - not a finding that asbestos was aboard any listed hull. The exhibit's Mare Island window IS corroborated by this hull's documented record: DANFS places Cavalla at Mare Island Naval Shipyard for her first major overhaul and refueling September 1987-February 1990 - inside BOTH of the exhibit's date-range annotations ('1974-1991' and '1984-1995'), so the claimed window holds regardless of column-block assignment. The exhibit does not fix which duties involved this hull - presence is corroborated, contact and material condition are not. Establishes nothing about materials aboard this hull, exposure of any individual, quantity, or eligibility.

[4]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]

- class/era synthesis (no ship-specific document)
- Finding type
- asbestos_application
- Finding
- Era inference: a Sturgeon-class nuclear attack submarine built 1970-73 at Electric Boat, Groton, and maintained through Puget Sound and a documented 1987-1990 Mare Island overhaul/refueling 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, Puget Sound NSY, Mare Island NSY) are recorded in the shipyard-exposure-map dataset.

- Shipyard construction trades (1970-73); yard availability trades; crew (1973-1998)
- 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.

- 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.

[6]Batch-40 search ledger (this record): NHHC DANFS, archived Naval Vessel Register detail pages, CourtListener docket records via RECAP archive, GAO program documentation [other_primary]
- Locator
- synthesis of the ship's search-ledger rows
- Finding type
- historical_record
- Finding
- No qualifying ship-specific asbestos record located for USS Cavalla (SSN-684): no asbestos survey, abatement contract, hazmat disclosure, or adjudicated exposure finding naming this hull was found. The Cooks exhibit naming this hull is a pleading-stage allegation (window corroborated by the documented 1987-1990 Mare Island overhaul). No adjudicated exposure finding, ACM survey, or abatement record naming this hull was located.

- 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.
