- Limitations
- Service-history source only. DANFS documents construction, milestones, and operations; it contains no asbestos, materials, or exposure information. Live NHHC page returned HTTP 404 in this environment; Wayback capture and print scan used. Note: navysite renders the keel date as 2 October 1962 - a typo; DANFS and NVR both give 2 October 1961.

- Finding
- Asbestos complaint Exhibit A (multi-plaintiff work-histories; section for plaintiff Robert Schoelzel, a Puget Sound Naval Shipyard marine mechanic May 1983-1986) lists 'NATHAN HALE (SSBN-623)' in an alphabetical roster of vessels worked on or around at that yard. Schoelzel was diagnosed with asbestosis in or about January 2006; duty recitals describe marine machinery mechanic work on ships and submarines at the yard.

[3]Halseth v. General Electric Co., No. 3:07-cv-02543-EMC (N.D. Cal.), consolidated complaint Exhibit A work-histories, ECF No. 1-2 (filed 2007-05-14); retrieved via Internet Archive RECAP mirror (gov.uscourts.cand.192004.1.1.pdf) [court_record]

- Finding
- Asbestos complaint Exhibit A (consolidated multi-plaintiff work-histories; section for plaintiff Larry Robinson, a Puget Sound Naval Shipyard pipefitter 1975-2004) lists 'NATHAN HALE (SSBN-623)' in an alphabetical roster of vessels he worked on or around. Duty recitals describe repairing, replacing and modifying piping systems on nuclear and non-nuclear ships in engine rooms, fire rooms and reactor rooms; changing steam-trap gaskets; and working in close proximity to pipefitters, laggers, machinists, electricians and painters 'blowing around asbestos dust,' around General Electric and Westinghouse turbines and Johns-Manville insulation.

- Limitations
- Milestone/disposal register only; NVR carries no asbestos or materials data. The recycling-completion date is the disposal event, not an abatement or hazmat record. NVR resolves the secondary-source stricken-date error (navysite's '31 January 1986' precedes the documented 3 November 1986 decommissioning; NVR stricken is 31 December 1986).

[6]Era inference anchored to DANFS/NVR-documented construction and yard periods for this hull [other_primary]
- Locator
- construction-era inference from DANFS/NVR dates and yard periods
- Finding type
- asbestos_application
- Finding
- Era inference: a first-generation ballistic-missile submarine built 1961-63 at Electric Boat in the peak asbestos era would era-typically have carried asbestos-containing insulation, gaskets, and packing around its secondary steam and auxiliary machinery (S5W steam plant, turbines, pumps, valves); refit and upkeep yard periods are the kind of disturbance windows in which era insulation was installed and removed. Nuclear propulsion itself establishes nothing about asbestos; the inference attaches to conventional steam-side systems only.

- Finding
- Negative finding: no hull ACM survey, abatement contract, recycling-hazmat disclosure, materials schedule, or adjudicated exposure finding naming USS Nathan Hale (SSBN-623) was located. Ship-specific asbestos-adjacent records are two pleading-stage roster allegations (ev-02..03).
