- Population
- EB construction trades (1943); crew (1944-1945, all hands lost)
- Limitations
- Structured volunteer-compiled historical data, not a federal primary source. No verbatim DANFS entry was located for Barbel - the loss narrative rests on NavSource plus standard secondary accounts and should be treated as archival-lead strength. No asbestos or material content. Direct navsource.net fetch is Mod_Security-blocked; content captured via search-result text.

[2]Balao-class profile (ships-worktrees class-f/balao-class.class.json) - class-level propulsion and asbestos-relevant pathway context [other_primary]
- Locator
- class-f/balao-class.class.json (house class profile)
- Finding type
- asbestos_application
- Finding
- Balao-class context: diesel-electric fleet submarines with no boilers or steam plant; era-consistent asbestos pathways for the class include diesel-exhaust lagging, engine gaskets and packing, acoustic/thermal hull insulation, galley and refrigeration materials, and battery/electrical materials. Construction (1943, Electric Boat) falls inside the Navy's peak asbestos-use era.

- Limitations
- Class/era inference only - does not name this hull and does not establish that any particular asbestos-containing material was installed aboard SS-316. Hull lost February 1945; no survey possible.

[4]CourtListener API v4 (2026-09-18): sweeps for "USS Barbel" / "Barbel" and "SS-316" could not be executed - anonymous quota exhausted (HTTP 429) [court_record]
- Locator
- search_ledger rows sl-uss-barbel-ss316-04 through sl-uss-barbel-ss316-05
- Finding type
- historical_record
- Finding
- CourtListener litigation sweep NOT COMPLETED for this hull: the shared anonymous API quota (125 requests/day) was exhausted before this vessel's queries ran; every request returned HTTP 429 ('Expected available in ~69,771 seconds' at last check). No qualifying asbestos litigation was located in the other sources searched, but CourtListener coverage is absent rather than negative for this hull. Collision risk noted: namesake USS Barbel (SS-580, 1959-1989).

- Limitations
- CourtListener gap is an absence of coverage, not a negative finding - no docket data of any kind was retrieved for this hull. State-court and non-digitized records are also uncovered. Sweep should be re-run under an authenticated API token in a future pass.

- Finding type
- historical_record
- Finding
- No qualifying ship-specific asbestos record (survey, abatement contract, industrial-hygiene report, or docketed case) naming this hull was found in the public sources searched; CourtListener coverage was unavailable due to quota exhaustion (see search_ledger).

- Limitations
- Does not establish absence of asbestos aboard - only absence of located public documentation. Hull lost 1945 with all hands; next-of-kin and workers' claims may exist in non-digitized records. Does not establish or defeat any claim of exposure or legal eligibility.
