- Finding type
- asbestos_application
- Finding
- Balao-class diesel-electric boats carried NO boilers or steam plant (BuShips 1945: DERD drive, four main diesel-generator engines, 5,400 hp, two shafts). Era-typical asbestos-relevant applications on the type: diesel exhaust lagging, engine gaskets and packing, acoustic and thermal hull insulation, insulation around galley and refrigeration equipment, and battery/electrical materials. The Electric Boat/Groton yard's asbestos product use in submarine construction of this era is independently documented at the yard level.

- CourtListener API v4 and HTML search returned HTTP 429/403 to automated fetches during this window; the sweep was completed via a search-engine index of the courtlistener.com domain, which has weaker recall than the native index - a residual unverifiable margin exists. Absence of a located public docket does not prove absence of exposure or of filings; state-court and non-digitized records are not covered.
