   Finding

   NavSource's live YMS-89 hull page identifies this vessel as a YMS-1-class auxiliary motor minesweeper: laid down 11 July 1941 by Hubbard's South Coast Co., Newport Beach, CA; launched 22 November 1941; completed 11 June 1942; struck from the Naval Register 1 May 1946; transferred to the War Shipping Administration in September 1947; fate unknown. Call sign Nan-Uncle-Queen-Item. Specification block: displacement 270 t.; length 136'; beam 24' 6"; draft 8'; speed 15 kts.; complement 32; armament one 3"/50 dual-purpose gun mount, two 20mm mounts, and two depth charge projectors; propulsion 'Two 880bhp General Motors 8-268A diesel engines, Snow and Knobstedt single reduction gear, two shafts.' The page carries a complete commanding-officer roster (8 officers, LTJG Andrew Morthland USNR 11 June 1942 through ENS Maurice S. Childs USNR ending 17 April 1946) and a c. 1945 U.S. Navy photograph credited to the Naval History and Heritage Command (NH 79687). The page states that no DANFS history is available for YMS-89.

   Limitations

   NavSource is a specialist naval-history archive rather than the underlying Navy register or a DANFS entry; the page provides no operational narrative and no asbestos/material-content statement. 'Completed' vs 'commissioned' wording is carried verbatim - uboat.net renders the same date as 'Commissioned'. The September 1947 'War Shipping Administration' transfer postdates WSA's formal abolition (1 Sep 1946, NARA RG 248 finding aid) - custody terminology flagged in gaps. The NH 79687 NHHC image page could not be verified (NHHC numerical image URLs 404 - standing link-rot defect); the photo is cited from NavSource's caption only.

   Specialist secondary compilation - corroborates builder, laid-down/launch/in-service dates, and the 1 May 1946 stricken date. 'Ordered 1 April 1941' rests on uboat.net alone (not in NavSource or Colton) - secondary-only, not carried into a date field. Its Morthland tour dates (23 Jun 1942 - 29 Mar 1943) differ slightly from NavSource's roster (11 Jun 1942 - March 1943) - flagged in the correction row and gaps. Renders 'Completed' as 'Commissioned' - a status-wording distinction noted in the commissioned field. Contains no asbestos information.

This is an archival log-coverage entry, not a commissioning or decommissioning date - but its 11 June 1942 start coincides exactly with NavSource's 'Completed 11 June 1942' and uboat.net's 'Commissioned 11 Jun 1942' dates.

The coverage dates must not be substituted for service-status dates; the log run ending 30 June 1945 does not show the hull out of service - the record carries it into the July-September 1945 demobilization window undocumented.

The '500 h.p.' figure is internally implausible against the GM 8-268A pair's ~880 designed shaft horsepower - reported as printed. No asbestos content.

   Finding

   GAO's 1979 review addressed asbestos use in Navy ships, the cost of removing asbestos from Navy ships, and Navy protection of shipyard workers. Its official summary states that the Navy's 1975 policy was to remove and replace with nonasbestos materials only insulation that was damaged or had to be removed to accomplish necessary repairs, with a 1979 modification for selected high-maintenance areas.

   Limitations

   Program-level Navy evidence, not a YMS-89 record. It supports era context only and does not prove installation, location, condition, disturbance, quantity, exposure, or causation aboard this hull. YMS-89 left Navy custody in 1947 - decades before the documented 1975/1979 replacement policies - so the report's policy content does not describe any event in this hull's life; it establishes only the era's use-then-removal framing.

   Finding

   Era/class inference only: YMS-89 was a wooden-hulled YMS-1-class diesel minesweeper built 1941-42 and operated 1942-46 during the Navy's documented WWII-era asbestos-use period. Possible maintenance-related applications include diesel exhaust lagging, gaskets, valve packing, electrical insulation, and brake linings; no one of these applications is confirmed aboard YMS-89.

   Class/era inference only. It does not establish that asbestos was installed aboard YMS-89, identify a manufacturer or product, quantify material, establish remaining ACM, or prove exposure or causation. The vessel's diesel plant and wooden hull mean boiler/turbine lagging is not asserted, and plausible scope is confined to machinery fittings - materially less than steam-driven vessels.

    Failure to locate a public record does not prove absence of asbestos aboard the hull - a 1941-42-built vessel is era-consistent with asbestos-containing machinery fittings even accounting for the lighter diesel insulation load. Undigitized or uncataloged RG 19/RG 24 records (including this hull's own SL-44-indexed deck logs at Archives II) remain open leads.
