- Ship-specific history only; no asbestos or material content. The live NHHC DANFS page returned HTTP 404 in this environment - the citation is a verbatim transcription mirror (losthistory.net/hazegray); defect disclosed. The DANFS narrative is thin for this hull - post-1965 detail rests on secondary compilations (navysite).

- Asbestos complaint exhibit (plaintiff Alvin Cooks's work-history/exposure roster; Mare Island marine machinist 1974-1995 alleged) lists 'JOHN C. CALHOUN' and 'SSBN-630' among the vessels on which the plaintiff alleged asbestos exposure.

- Complaint-exhibit vessel list; unadjudicated pleading-stage allegation. The listed hulls are places the plaintiff claimed exposure occurred, not findings that asbestos was aboard any listed hull. Establishes nothing about materials aboard this hull. Verified by direct text extraction of the stamped Exhibit A PDF.

[9]Era inference anchored to DANFS-documented construction and yard periods for this hull [other_primary]
- Locator
- construction-era inference from DANFS dates and documented yard periods
- Finding type
- asbestos_application
- Finding
- Era inference: a nuclear submarine built 1962-64 at Newport News in the peak asbestos era would era-typically have carried asbestos-containing insulation, gaskets, and packing around its secondary steam and auxiliary machinery; the documented Mare Island Poseidon-conversion overhaul (1969-71) is a yard-disturbance window of the kind in which era insulation was installed and removed. Nuclear propulsion itself establishes nothing about asbestos; the inference attaches to the conventional steam-side systems.

- Limitations
- CLASS/ERA INFERENCE ONLY - no ship-specific material schedule, survey, or insulation record was located for this hull. Does not establish asbestos aboard USS John C. Calhoun, 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 era (1962-64) and the 1969-71 Mare Island Poseidon conversion; the 1984-86 Charleston refueling overhaul postdates the documented substitution window.

[11]Negative finding: no qualifying non-litigation ship-specific asbestos record located across DANFS/NHHC, NVR, museum, and ACM-survey/abatement/disposal sweeps [other_primary]
- Locator
- see search_ledger sl-uss-john-c-calhoun-ssbn630-01..08
- Finding type
- historical_record
- Finding
- No hull ACM survey, abatement contract, scrapping/recycling hazmat disclosure, or merits-level adjudicated exposure finding naming USS John C. Calhoun (SSBN-630) was located. Litigation sweeps produced one pleading-stage complaint-roster allegation naming the hull (Cooks - unadjudicated); no merits-level record or opinion names this hull. Name searches also surfaced unrelated Confederate/political-history material - collisions screened out.

- Absence of a located record is not proof no record exists - the 1994 recycling-disposal path left no retrievable hazmat-disclosure trail in located sources. The roster allegation remains pleading-stage only.
