Specification block: displacement 270 t.; length 136 ft; beam 24 ft 6 in; draft 8 ft; speed 15 kts; complement 32; armament one 3"/50 dual purpose mount, two 20mm mounts, two depth charge projectors; propulsion two 880 bhp General Motors 8-268A diesel engines, Snow and Knobstedt single reduction gear, two shafts. Call sign Nan-Queen-Item-Charlie. Photo captions document: the 20 March 1943 launching (tallow congealed by cold slightly delayed the launch; yard officers Fred Bianco, Robert Scobie, R. B. Bivins, and William Larsen attended); the ship 'Sweeping Manila Harbor, Philippines'; and 28 December 1945 at Shanghai, China, where YMS-338, YMS-6, YMS-8, YMS-53, and YMS-51 were part of the minesweeping force on the Huangpu River (photo from the collection of LTJG Jack W. Norris, XO, YMS-56). The page states: 'There is no DANFS history available for YMS-338.'

- NavSource is a live secondary photo-archive compilation, not an official registry. It supports the stated timeline, specification block, call sign, photo captions, and absence of a DANFS entry only; it styles 12 August 1943 'Completed' rather than 'Commissioned'. The Manila Harbor photo caption carries no date. Establishes no asbestos information.

- Finding
- NARA's Special List #44, by Ship Numbers, indexes deck-log coverage for YMS-338 in a single interval: 12 August 1943 through 30 September 1945 - matching the batch-supplied fact exactly and corroborating the in-service start date (completion/commissioning day). Notably, the indexed coverage ends 30 September 1945 while her documented service continued into 1946 (post-war minesweeping off China through March 1946 per the NHHC awards table and the Bunch DANFS entry); logbooks for October 1945 onward are not indexed under this list for this hull.

- Finding
- The official NHHC DANFS entry for USS Bunch (DE-694, later APD-79) names this hull: 'In January 1946, Bunch moved to Taichow, China, where she carried out minesweeping duties in cooperation with YMS-338, YMS-329, and YMS-366 before shifting to Wenchow Bay to do a minesweep radar plot.' This is an official-source ship-specific service fact placing YMS-338 on post-surrender minesweeping operations off the China coast in January 1946.

- Finding
- The Navy and Marine Corps Awards Manual (1953 revision), Part IV 'List of Ships and Units Eligible for Engagement Stars' (Asiatic-Pacific area), lists YMS-338 with four date/code entries: 27 June - 15 July 1945, code P37-3 (the Balikpapan operation of the Borneo operations, overall window 15 June - 20 July 1945); 9 December - 16 December 1945, code P207 (Minesweeping Operations Pacific, overall window 23 June 1945 - 2 March 1946); 15 February - 2 March 1946, code P207-26 (Yulinkan Bay area); and 1 March - 2 March 1946, code P207-27 (East Hainan area). This documents engagement-star eligibility for the Balikpapan minesweeping operation in mid-1945 and post-surrender minesweeping operations off China in December 1945 - March 1946.

It documents where the Navy credited the ship as operating; it is not a day-level operational log, contains no asbestos information, and does not by itself prove combat contact at Balikpapan beyond the manual's own star-eligibility rules ('honorable service in a ship at the time it participated' in the operation).

- The same awards manual's Part IV, sec. 18 'Units Eligible' table (Navy Occupation Service Medal and China Service Medal (Extended)) lists 'YMS 338' with a single entry in the Dual eligibility column: 2 September 1945 - 12 March 1946 - i.e., service in that window was creditable toward both the Navy Occupation Service Medal and the extended China Service Medal. This independently corroborates the hull's post-surrender presence in Asiatic-Pacific/China waters through 12 March 1946.

- Shipbuilding History's yard table for Seattle Shipbuilding & Drydocking Company (Seattle, WA) lists the row 'YMS 338 | US Navy | Minesweeper | 278d [tons] | [built] 12-Aug-43 | Struck 1946', among a consecutive run of sisters (YMS-334 through YMS-341) built at the same yard in 1943. The page's yard history states the company 'was started by Fred Bianco in the 1930s and closed in the 1950s' at 2629 NW 54th Street in Ballard - 'not to be confused with the big yard of a similar name which subsequently became Todd Seattle' (i.e., Seattle-Tacoma Shipbuilding). The Fred Bianco identification matches the NavSource launching caption naming 'Fred Bianco, president of the shipbuilding corporation' as an attendee of this hull's 20 March 1943 launch.

'Built' and 'Struck' are summary labels. Establishes no asbestos information.

- Finding type
- vessel_history
- Finding
- NavSource's Auxiliary Motor Minesweeper index establishes the class context: the YMS type was a wood-hulled motor minesweeper; 561 hulls were built 1942-45 at 35 yacht yards (12 East Coast, 19 West Coast, four Great Lakes); they were numbered rather than named, originally rated as service craft, and used for WWII inshore sweeping ahead of amphibious assaults; YMS-135 through 445 (the appearance group containing this hull) carried a single stack; surviving YMS hulls were reclassified AMS in 1947 and given names - explaining why this hull, stricken 19 June 1946, was never named. The HyperWar mirror of Ships of the U.S. Navy, 1940-1945 (Minecraft section) lists this hull in the fleet table as 'YMS-338' with no name and service notation '1942-5'.

The HyperWar '1942-5' table entry is an ambiguous service notation, not an individual history. Neither source contains asbestos information.

- historical_record
- Finding
- NARA's deck-log research guidance explains the record path for this hull's logs: deck logs of commissioned Navy ships are permanent records held in Record Group 24, with 1941-and-later logs generally at College Park, Maryland, and finding aids (including Special List #44) indexing coverage by ship number. NARA also notes that only some Navy records have been digitized. This frames the indexed YMS-338 coverage (ev-03) - the logbooks for 12 August 1943 - 30 September 1945 exist under RG 24 as the primary operational record for this hull, and were not reviewed.

The exact-name opinion query ('USS YMS-338', type=o, limit 20) completed with count 0. The remaining three base queries (exact-name docket; 'YMS-338' opinion; 'YMS-338' docket) were repeatedly declined by the authenticated helper's fleet-wide pacing gate across spaced attempts during this session; those are access gaps, not zero-result findings. No asbestos-qualified variants were run because no completed base query overflowed its 20-result page.
