- Finding
- Special List 44 (by ship number) lists deck-log coverage for YMS-265 spanning 3/6/1943 - 6/30/1945 (PDF page 117, row 'YMS-265 3/6/1943 6/30/1945'). These logbooks are RG 24 (Bureau of Naval Personnel) material at the National Archives. The begin date coincides with the hull's documented in-service/completion date (6 March 1943 per NavSource).

- Logbook custody coverage, not service dates: the begin/end columns are the extents of logbooks held, NOT commissioning or decommissioning dates. Coverage ends 6/30/1945 in this list - the hull's post-surrender service (documented into Feb 1946) is not represented in SL44's listing; later logs may exist in post-1941 RG 24 accessions at NARA College Park (open lead). No asbestos content.

'Completed' vs 'Commissioned' wording differs from uboat.net (see gaps). Contains no asbestos content. No hazmat or material record for the post-1968 career or disposal was located.

- Finding
- YMS-265 is credited with two post-surrender operations under the Asiatic-Pacific Campaign's P207 'Minesweeping Operations Pacific' series: Nagoya (Honshu Area), 28 Sep 1945 - 25 Oct 1945, operation code P207-3 (operation window 28 Sep - 26 Oct 45); and Kure-Hiroshima (Honshu Area), 8 Jan 1946 - 23 Feb 1946, operation code P207-10 (operation window 27 Oct 45 - 26 Feb 46). These are the occupation-era sweeps of Japanese minefields credited to surviving YMS hulls after the surrender.

P207-series credits are post-surrender occupation minesweeping, not combat action. No asbestos content.

- Finding type

- Finding
- CORRECTION: NavSource prints the builder as 'Krause and Banks Shipbuilding Co.'; the correct name is Kruse & Banks Shipbuilding (Co. Inc.), confirmed by this yard history, uboat.net, and jounin.jp. Yard history: founded by Knut V. Kruse 1902, joined by Robert Banks 1905, moved from Marshfield to North Bend OR about 1909, closed 1946 (site sold to Weyerhaeuser). The build list places YMS-265 (US Navy minesweeper, 278 t., 136', completed 6-Mar-43, struck 1947) among the yard's North Bend hulls alongside sisters YMS-266/267/268 and YMS-121 through -124.

- Finding type
- asbestos_application
- Finding
- A diesel-powered wooden-hulled minesweeper built 1942-43 sits inside the Navy's documented asbestos-use era; era-standard applications aboard a vessel of this type and period were engine exhaust and machinery insulation, gaskets, valve packing, electrical insulation, and winch/windlass brake linings. As a diesel craft she carried no steam plant - the boiler/turbine lagging pathway of steam vessels does not apply - and her wooden hull reduced structural insulation scope relative to steel combatants.

- GAO documented that the Navy used asbestos insulation extensively aboard ships and did not begin substituting alternative insulation materials until the early 1970s - spanning this hull's entire construction (1942-43) and naval-service era (1943-47).

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or docketed case naming USS YMS-265 (YMS-265) was found in the public sources searched (see search_ledger). CAVEAT on litigation completeness: of the four required CourtListener base queries, only "YMS-265" opinion completed (0 results); the remaining three (YMS-265 docket; USS YMS-265 opinion and docket) were refused all session by the fleet-wide pace budget (HTTP pacing stand-down, ~40 min of spaced retries) - logged as blocked, not as negative results. Secondary web sweeps surfaced neither qualifying litigation nor even law-firm marketing claims for this hull - the asbestos-claim listicles that blanket better-documented hulls do not list YMS-265.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - era-consistent material inference stands independently, and the litigation repository search is a genuine open gap (3 of 4 base queries throttled, not run). Deck logs (SL44 coverage 1943-45, later RG 24 accessions thereafter), WSA transfer file, and any Canadian-registry survey documents are undigitized leads. Does not establish or defeat any claim of exposure or legal eligibility.
