- 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 - diesel maker Fairbanks-Morse or General Motors varying by hull block, electric motors Elliott or General Electric, ~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.

- 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 entire active service period (1944-1969).

- search_ledger rows sl-uss-charr-ss328-01 through -05
- Finding type
- historical_record
- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or adjudicated case naming USS Charr (SS-328) was found. CourtListener sweeps pending (rate-limited in this window - see search_ledger). Sold for scrap August 1972 - the pre-NESHAP timing means no federal asbestos-handling record would be expected for the disposal itself.
