- Locator
- DANFS construction sentence vs commissioning sentence; NVR builder field; COR 1976-77
- Finding type
- historical_record
- Finding
- CORRECTION / source conflict on builder: the DANFS narrative states the boat was 'laid down on 8 January 1972 at General Dynamics Electric Boat, Groton, Ct.' but the same DANFS entry records commissioning 'at Newport News Shipbuilding & Dry Dock Co., Newport News, Va.' The Naval Vessel Register records builder Newport News Shipbuilding, and the hull's own 1976-77 command history states she was launched by Newport News Shipbuilding. NVR + primary COR control: builder is Newport News Shipbuilding & Dry Dock Co.; the DANFS 'Electric Boat' line is internally inconsistent and treated as an error.

- GAO product page HRD-80-2 (full text blocked, HTTP 403)
- 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. Her 1972-76 construction and her 1977-2006 availabilities (Norfolk NSY, Newport News, Pearl Harbor NSY, Mare Island NSY, Electric Boat) span the pre- and post-substitution period; substitution timing does not resolve which materials were installed in this hull.

- litigation_documented
- Finding
- Court-documented era regime: Navy thermal-insulation procurement specifications (32-I-3/MIL-I-2819 block and 32-P-8/MIL-I-2781 pipe insulation) required asbestos-containing thermal insulation in naval construction and repair; submarine insulation specs (SUBSAFE-era MIL-I-24244) covered submarine construction and overhaul. These regimes were in force during this hull's 1970s construction and service-era availabilities.

- Finding
- A first-flight Los Angeles-class boat built 1972-74 at Newport News Shipbuilding and maintained through Navy-yard availabilities at Norfolk NSY, Pearl Harbor NSY, Mare Island NSY and Electric Boat across 1977-2006 sits at the edge of the Navy's peak asbestos-use era: substitution began in the early 1970s, but era-standard asbestos applications (thermal/pipe insulation, gaskets, packing, machinery insulation on the secondary steam plant and auxiliary systems - not reactor internals) remained common in shipyard work through the decade and in repair material thereafter.

- Builder-yard construction trades; Navy-yard availability trades; crew
- Limitations
- Class/era inference only - no hull-specific insulation survey or material list located. Names era-standard applications on secondary steam and auxiliary systems, not confirmed installed materials; the S6G reactor plant establishes nothing. This hull was built during the Navy's early-1970s asbestos-substitution transition, so original-asbestos inference is weaker than for 1950s-60s hulls and remains unverified either way. No quantity; current material condition undocumented.

- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or qualifying asbestos case naming this hull was found. CourtListener API searches could not be run (125/day rate limit exhausted; reset ~15h) - Google-indexed CourtListener documents surfaced no document naming this hull as an exposure site; all surfaced hits were name collisions or unrelated litigation.

- Absence of a located public record does not prove absence of asbestos aboard. A negative public-record search is not a materials survey; yard work-package and hazmat records, if they exist, are not public. CourtListener coverage was partial (API throttled; Google-indexed corpus only). Does not establish or defeat any claim of exposure or legal eligibility.
