- NavSource archive record for this hull: originally planned as coastal minesweeper Clamour (AMc-137); reclassified AM-160 on 21 February 1942; laid down 26 May 1942 by Willamette Iron and Steel Corp., Portland, OR; launched 15 December 1942 [conflicts with both official sources - see gaps]; commissioned USS Clamour (AM 160) on 14 March 1944; decommissioned 12 June 1946 at San Diego, CA; the Naval Vessel Register of 1 January 1949 lists her out of commission, in reserve; reclassified fleet minesweeper (steel hull) MSF-160 on 7 February 1955; scrapped in 1959. Commanding-officer roster printed (LCDR Davis M. Lott, USNR, 14 March 1944 - 18 August 1944, and successors). Spec block (650 t.; 184'6" x 33' x 9'9"; 14.8 kts; complement 104; 1 x 3"/50 DP, two twin 40mm, hedgehog, two depth-charge tracks; two ALCO 539 diesels, Farrel-Birmingham single reduction gear, two shafts) is consistent with the official NAVSHIPS table where they overlap.

The launch date conflicts with DANFS and NAVSHIPS (both print 24 December 1942) and matches sister Change AM-159's official launch date - treated as a compilation error; official sources carried. No Navy List striking date printed. No materials or asbestos content.

- Opinion text, 627 F.3d 1293 at 1296-1297 (Background; employment dates; stipulation)
- Finding type
- litigation_documented
- Finding
- Published appellate opinion records an LHWCA death-benefits claim by the widow of James McAllister, a shipyard carpenter who died of mesothelioma from asbestos exposure across three shipyard employers: Willamette Iron & Steel Co. ('WISCO'), Albina Engine & Machine, and Lockheed Shipbuilding. All parties stipulated the death was caused by asbestos exposure at a maritime situs; the opinion notes 'WISCO admitted that Decedent was exposed to asbestos in its employ.' WISCO is the builder of this hull (the Atlas yard dataset lists 'WISCO' as an alias of Willamette Iron & Steel Corp., Portland, OR). The Ninth Circuit resolved only which employer was liable for benefits under the last-employer framework, holding Lockheed liable.

- Limitations
- Yard-level context, not a hull finding: McAllister's WISCO employment was in 1956 - more than a decade after this hull's 1942-44 construction - so the documented exposure window does not overlap the build period. The opinion names the employer, not AM-160, and adjudicates an LHWCA liability-allocation question only; exposure at WISCO was stipulated/admitted, not tried. Does not establish conditions aboard any vessel or during the wartime window. CourtListener API was unavailable on 2026-09-22 (shared daily quota exhausted); opinion read via vLex.
