- Finding type
- historical_record
- Finding
- Contemporary reporting documents the Aggressive (AM-421/422)-class design: class lead USS Aggressive was 'constructed ... largely of small pieces of wood glued and pressed together,' with laminated stems, keelson and frames - the wooden-hulled, non-magnetic, diesel-powered construction that defines this class's material profile and rules out the steam-plant asbestos applications typical of WWII combatants.

- Study period
- 1952 (class design era)
- Limitations
- Describes the class lead ship at launch, 1952 - class-level construction fact, not a hull record for Gallant. Contains no asbestos information; wooden/diesel construction context means steam-plant insulation applications do not apply to this design, but it does not establish absence of other era-typical ACM.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, museum record, or docketed case naming USS Gallant (AM-489/MSO-489) was found in the public sources searched (see search_ledger). CourtListener web-index name searches returned only name collisions (United States v. Gallant Pharma International, Gallant Insurance Co., USA v. Gallant/BestBank); the authenticated CourtListener API was rate-limited at batch time (2,800/day exhausted, ~6-hour backoff), so the exhaustive docket-level pass is incomplete rather than conclusively empty. Law-firm 'asbestos ship' listicles naming USS Gallant are excluded per batch rules as banned source classes - they carry no primary support.

- Absence of a located public record does not prove absence of asbestos aboard - 1950s-era construction is consistent with era-typical ACM in gaskets, packing, exhaust lagging, deck coverings, and electrical/interior materials. Does not establish presence or absence; does not establish or defeat any exposure claim or legal eligibility.

M. Martinac yard records and the Tacoma Public Library Richards Studios photo collection hold builder-era documentation.
