- Finding type
- asbestos_application
- Finding
- Peer-reviewed historical study documents that asbestos was used extensively as a fireproofing and insulating material in U.S. shipbuilding during WWII - the era and Navy-contract construction program under which this hull was built at Charleston in 1943-44. Wartime demand drove unprecedented asbestos utilization in ship construction.

- Limitations
- Program/era-level scholarship; does not name this vessel or class and does not establish that asbestos was or remains aboard this hull, nor quantity, location, condition, exposure, or causation. As a diesel-electric hull (no boilers or steam mains), steam-plant-specific inferences do not transfer to this ship.

- Finding
- No qualifying asbestos litigation naming this hull located. Results classified: 'Hidatsa' (type=o) - 41 opinions, ALL name collisions with Mandan, Hidatsa and Arikara Nation / Three Affiliated Tribes / Fort Berthold tribal-law matters; none ship- or asbestos-related. 'Hidatsa' asbestos - 0. 'USS Hidatsa' - 0. 'ATF-102' - 0. 'ATF-102' Hidatsa - 0. 'AT-102' Hidatsa - 0. 'Hidatsa' (type=r dockets) - 203 dockets; page-1 review (top-ranked) all tribal/geographic collisions (Indian law, North Dakota criminal/civil, bankruptcy), zero asbestos. Bare 'AT-102' - 24,369 non-discriminating pattern hits (addresses, citations, numbers), unusable as a ship discriminator.

- Limitations
- Sweep coverage is CourtListener opinion + RECAP docket text; PACER-only filings, state-court systems, and settled/undocketed matters are outside coverage. WWII Navy-hull asbestos claims typically ran against the U.S. government or product manufacturers rather than naming hulls - a negative hull-name result does not prove no claimant served aboard. All ship-discriminating conjunctions returned zero.

- search_ledger rows sl-uss-hidatsa-at102-01 through sl-uss-hidatsa-at102-10
- Finding type
- historical_record
- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat or disposal disclosure, or docketed asbestos case naming the Hidatsa hull was found in the public sources searched (see search_ledger). The MARAD custody cards carry no materials data, and the hull left U.S. custody in 1979 - predating the NDRF disposal-era hazmat documentation generated for scrapped Suisun Bay vessels. Web sweep surfaced only law-firm marketing listicles naming the hull on tug/asbestos lists - excluded per batch source rules.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - a 1943-44 wartime-built Navy auxiliary is era-consistent with asbestos-containing materials, and any post-1979 surveys would sit in Colombian records outside U.S. public sources. Does not establish presence or absence; does not establish or defeat any claim of exposure or legal eligibility.

[9]Source-discrepancy resolution across DANFS (NHHC/Wayback), MARAD status cards, NavSource, and secondary references (Wikipedia, Navypedia, uboat.net) [other_primary]

- Finding type
- historical_record
- Finding
- Discrepancies resolved or logged: (a) Class name - DANFS header reads 'cl. Cherokee' while NavSource and modern references use 'Abnaki class'; the Cherokee/Abnaki designations overlap in the wartime AT/ATF 66-172 group; record carries Abnaki per modern convention, DANFS header noted. (b) Propulsion - Wikipedia infobox '4 x GM 12-278A' is contradicted by this hull's MARAD status card ('B.S. Diesel Elec.') and NavSource spec (four Busch-Sulzer BS-539); Navypedia's per-hull split likewise assigns Busch-Sulzer to RM-74 vs GM on sisters RM-72/73. Busch-Sulzer adopted as this hull's fit. (c) Colombia dates - NavSource 'cash sale 1 March 1979' vs MARAD card 'withdrawn by Navy / permanent transfer 3-15-79': treated as sale-agreement vs custody-withdrawal events, both documented. (d) Keel-laid - NavalCoverMuseum '8 August 1943' is uncorroborated by DANFS/NavSource; carried in gaps, not asserted. (e) Colombian disposal - 1998 (Wikipedia) vs stricken 1999 (Navypedia) vs in-service 2003 (uboat.net); unverified, carried in gaps.
