   Finding

   NavSource's live YMS-308 hull page identifies this vessel as a YMS-1-class auxiliary motor minesweeper: laid down 25 February 1943 by Henry B. Nevins, Inc., City Island, NY; launched 21 July 1943; completed 27 August 1943; grounded during Typhoon Louise October 1945; refloated 6 November 1945; struck from the Naval Register 8 January 1946 and destroyed. The page gives call sign Nan-Peter-Oboe-Fox, lists Lt. D. D. Dupuy, USNR as commanding officer in 1945, carries a launch-day photograph dated 21 July 1943 at City Island credited to the Navy League of the United States, and states that no DANFS history is currently available for YMS-308.

It contains no asbestos or material-content statement.

Per NARA's asbestos research guide, muster rolls provide no direct evidence of asbestos - they can only show whether a particular sailor was assigned during periods when material-disturbing work occurred (see ev-09).

Dupuy as 1945 commanding officer.

   Finding

   The Department of the Navy's Navy and Marine Corps Awards Manual (NAVPERS 15,790, Rev. 1953), Part IV 'List of Ships and Units Eligible for Engagement Stars,' contains no YMS-308 entry: the YMS sequence runs YMS 305, YMS 307, YMS 309, YMS 311 with no 308 row (adjacent hulls YMS 307 and YMS 309 each carry a P207-10 entry dated 4-20 February 1946). This official absence is consistent with the veteran memoir's statement that YMS-308 'received no battle stars in WWII.'

   Finding

   A veteran memoir compiled from National Archives ship's-log research and crew recollections - 'USS YMS 339 ... an original history completed in 2009,' hosted by the Navy League's Westport, Connecticut council - records YMS-308 as author Maurice E. Fitzgerald's earlier minesweeper: she 'received no battle stars in WWII,' 'first served, with Maurice onboard, on the east coast and in the Caribbean, searching for German mines that weren't there and escorting convoys, while training new officers and crewmen,' and was 'later transferred to the Pacific.' The memoir states she was blown onto a reef by a typhoon at Okinawa, towed off by a sea-going tug, not fully repaired, decommissioned and struck from the naval registry in January 1946 at Okinawa, and that 'its ultimate fate is listed as "unknown"' - possibly sold for scavenging or scrapping.

   NavSource's YMS class index documents the type context: the first U.S. 'Yard class Minesweeper' (YMS-1) was designed by and built at Henry B. Nevins, Inc., City Island, NY - YMS-308's own builder - with keel laid 4 March 1941; the class was wood-hulled, built at 35 yacht yards (12 East Coast, 19 West Coast, four Great Lakes), with 561 built at various U.S. yards and 481 of the type sharing the same general characteristics; surviving YMS boats were reclassified AMS, named, and rerated in 1947. The index records that 'one of their greatest losses' came on 9 October 1945 'when seven U.S. YMS' were sunk in a typhoon off Okinawa' - the Typhoon Louise event in which this hull grounded.

The guide states that Navy deck logs and muster rolls (RG 24) 'do not provide any information on the use of or presence of asbestos in Navy ships or ship components and therefore provide no direct evidence of asbestos.' These records are the appropriate next archival lead for YMS-308; no such hull-level file was retrieved for this record.
