- Finding type
- vessel_history
- Finding
- NHHC's DANFS record identifies this hull as Cannon class, with displacement 1,240 tons, complement 186, and armament stated in its specifications block. It records construction by Western Pipe & Steel Co. at Los Angeles, California: laid down 11 February 1943, launched 6 June 1943, and commissioned 30 October 1943. DANFS further records decommissioning at Green Cove Springs on 14 June 1946, transfer to Peru under MDAP on 26 October 1951, striking from the Navy Register on 18 April 1952, and service as Castilla (D.61).

[4]GAO HRD-80-2, Navy Efforts To Protect Workers From Asbestos Exposure (Oct. 18, 1979) [gao]
- Locator
- GAO product page for HRD-80-2; published Oct. 18, 1979
- Finding type
- gov_survey
- Finding
- GAO's Navy-wide 1979 review reports that the Navy's major use of asbestos aboard ships was thermal insulation and describes a 1975 remove-and-replace policy for damaged insulation or insulation removed for repair. This is class/era context for a Cannon-class destroyer escort constructed in 1943 only.

- Population
- Navy shipyard workers and crews, program-wide
- Limitations
- Program-wide evidence, not a survey of DE-739; GAO fieldwork was at Long Beach and Norfolk. It neither establishes that thermal insulation aboard this hull contained asbestos nor identifies material, quantity, condition, exposure, or removal work aboard it.

[5]CourtListener API v4 authenticated litigation sweep, 2026-09-29 [court_record]
- Locator
- Authenticated helper: type=o, q="USS Bangust", limit=20; helper output: fleet-wide request budget momentarily spent. Subsequent required scopes not sent after stand-down.
- Finding type
- litigation_documented
- Finding
- The required authenticated CourtListener exact-name opinion query for "USS Bangust" was sent through the required helper, but the helper reported the fleet-wide pacing budget was momentarily spent before an API result. Per helper guidance, the exact-name docket query and both required "DE-739" opinion and docket queries were not completed or retried. No litigation classification or negative conclusion is drawn.

- Limitations
- CourtListener coverage is limited to its indexed opinions and federal RECAP dockets and cannot establish the absence of state trial-court filings, unindexed pleadings, or settlements. Here, no query returned a search result; the incomplete sweep is a pacing-limiter gap, not evidence of no litigation.
