- Finding type
- historical_record
- Finding
- This hull (AMc-60/YF-381, in Navy service 1941-1943, scrapped 1943) is distinct from USS Chanticleer (ASR-7), the lead ship of the Chanticleer-class submarine rescue ships, commissioned 20 November 1942 and struck 1 June 1973. The two vessels share only a name; no source links them, and no service, litigation, or exposure record for one should be attributed to the other.

- Finding
- No qualifying ship-specific asbestos record was located for this hull: no survey, abatement record, hazmat disclosure, or docketed case naming USS Chanticleer (AMc-60), YF-381, or hull AMc-60 was found in the public sources searched. CourtListener searches by exact ship name ("USS Chanticleer") and by hull designations ("AMc-60", "YF-381") returned zero opinions and zero dockets.

- Absence of a located public record does not prove absence of asbestos - it is uninformative either way for a hull that was never converted or outfitted to any specification. Does not establish presence, absence, or any exposure claim; does not establish legal eligibility.

- Finding
- Peer-reviewed historical study documents that asbestos was used extensively as a fireproofing and insulating material across U.S. Navy and merchant shipbuilding during the World War II era in which this hull was carried in Navy in-service status (1941-1943).

- Population
- WWII Navy and merchant shipyard workers and ship crews (class/era context, not this hull)
- Limitations
- Program/era-level scholarly documentation of asbestos use in WWII shipbuilding generally; does not name this vessel. Unlike a fully built-out combatant or auxiliary of this era, this hull is not documented to have ever received an engine, boiler, steam plant, or any outfit that would carry such materials - both of its planned conversions (AMc, then YF) were cancelled before completion. This row is background only and supports no class/era finding for this specific hull.

Witherbee / R. Lenahan; NARA RG 19 (Bureau of Ships) correspondence files may hold the record of the decision to cancel both the AMc-60 minesweeper conversion and the subsequent YF-381 covered-lighter conversion.
