- NavSource timeline for this hull: YMS-1 class auxiliary motor minesweeper; laid down 10 May 1942 by Mojean and Erickson, Tacoma, Washington; launched 11 November 1942; completed 24 April 1943 and commissioned USS YMS-222 the same day, assigned to the Pacific Fleet; decommissioned 4 April 1946; struck from the Naval Register 1 May 1946; transferred to the War Shipping Administration May 1947; registered 1948 to Bruce K. Swansey of Houston TX as tug Jeanie S. out of Wilmington DE (1949 call sign K-R-H-G); registered 1950 to William S. Wells of Southport NC as fishing boat Jeanie S.; fate unknown. Spec block: displacement 270 t (253 t in 1949 registration), length 136' (126.3' 1949), beam 24'6" (25' 1949), draft 8' (11.3' 1949), speed 15 kts, complement 32 (4 in 1949, 7 in 1950); armament one 3"/50 DP mount, two 20mm, two depth-charge projectors; propulsion two 880-bhp General Motors 8-268A diesels, Snow and Knobstedt single-reduction gear, two shafts. Commanding officers: LT Vernon A. Brown USNR (24 Apr 1943); LTJG R. S. Moorefield USNR (1945). Page states no DANFS history exists for YMS-222.

- Finding
- Builder corroboration: William Mojean and Olaf Ericson started the yard in 1925 and closed it at the end of the war; located at the extreme inland end of the Thea Foss Waterway on East D Street between Dock Street and South 21st, Tacoma. Build table entry: 'YMS 222, US Navy, Minesweeper, 278d tons, 136 ft, delivery 20-Apr-43, struck 1946.' Sister hulls at the yard: YMS 223 (to Britain as BYMS 2223), YMS 224 (struck 1946), YMS 225 (to Britain as BYMS 2225), PCS 1455, PCS 1456 (completed as YMS 479, later Waxbill AMS 39), YMS 426-429 (428 to USSR as T-525; 429 sold 1947 as Princess Laverne).

- Secondary shipbuilding-history compilation, not an official registry; documents the builder and a delivery date (20 Apr 1943) four days earlier than NavSource's completion/commissioning date - plausible as delivery-before-commissioning but unresolved (see gaps). Tonnage figure 278d differs from NavSource's 270 t. Contains no asbestos content; no yard asbestos or materials record exists for this small wartime yard.

- Finding type
- vessel_history
- Finding
- Class context: the first YMS (YMS-1) was laid down 4 March 1941 at Henry B. Nevins Inc., City Island NY; 561 hulls of the type were built at 35 yacht yards (12 East Coast, 19 West Coast, 4 Great Lakes) and 481 for the U.S. Navy, all to the same general characteristics; the only significant variation was stacks (two stacks YMS-1 through -134; one stack YMS-135 through -445, 480, 481 - the series containing YMS-222; none YMS-446 through -479). Wood-hulled, used for inshore sweeping ahead of amphibious assaults; survivors reclassified AMS and named in 1947, redesignated MSC(O) in 1955 (MSCO 1967); Ruff (MSCO-54), ex-YMS-327, last of type, struck November 1969.

- Limitations
- Class-level narrative only; does not name this hull's individual service. YMS-222 missed the 1947 AMS reclassification because she was already decommissioned and transferred to the War Shipping Administration (May 1947) - so no AMS name or number was ever assigned to this hull. No asbestos content.

- NARA Special List 44 (by ship number) inventories U.S. Navy deck logs held for YMS-222 covering 24 April 1943 - 30 June 1945 (p. 116 of the ship-number list). The coverage start date matches her commissioning date exactly. YMS-222 does not appear in NARA's digitized deck-log catalog (archives.gov 'Navy Deck Logs Available Online, 1941 and later' list, checked 2026-10-04), so the logs exist as physical RG 24 holdings (Bureau of Naval Personnel records, Entry 118).

Log coverage ends 30 June 1945 while the ship served to April 1946: whether later logs (Jul 1945-Apr 1946, covering the occupation-service window) are in this series or elsewhere in RG 24 is undetermined. No asbestos content in a log-inventory listing.

- Official Navy credit for this hull: the Asiatic-Pacific Area 'ship or unit, date, and star code' list carries 'YMS 222: 15 Feb 44 - 19 Feb 44, P22-8'. The manual's authorized operations index maps code P22-8 to the Green Islands landing (15-19 February 1944) under the Bismarck Archipelago operation (P22, 25 Jun 43 - 1 May 44). One engagement code credited = one campaign engagement star for this hull.

- Finding
- Official Navy credit for this hull: the Navy Occupation Service Medal units-eligible table ('Name of ship | Occupation service | Clasp | China Service | Dual eligibility') carries 'YMS 222 | 14 Sep - 3 Nov 45 | A' - Asiatic-area occupation service from 14 September to 3 November 1945 (clasp 'A' = Asia). This documents post-surrender duty in the Asiatic-Pacific area in the two months after V-J Day, consistent with forward-area minesweeping.

- Finding
- As of 1 May 1945 YMS-222 appears in the official Pacific Fleet organization under MINECRAFT, PACIFIC FLEET (Commander Minecraft, Pacific Fleet R. Adm. A. Sharp), in the pooled motor-minesweeper listing: 'YMS 222 | Lt. (jg) R. S. Moorefield (USNR)'. The row's task-organization column carries code '11', which in the same document's tactical-organization table maps to Task Force 11, South Pacific Force (V. Adm. W. L. Calhoun) - placing the hull in South Pacific service in the war's final months.

[10]Era inference built on: NavSource specifications (two GM 8-268A diesels, no steam plant); NavSource class index (wood-hulled type, same general characteristics across 481 USN hulls); GAO HRD-80-2 Navy asbestos-era documentation (see ev-10) [other_primary]

- Finding type
- asbestos_application
- Finding
- A wood-hulled, diesel-powered motor minesweeper built 1942-43 sits inside the Navy's documented asbestos-use era. As a diesel craft she carried no steam plant - the boiler/turbine lagging pathway of steam vessels does not apply. Era-standard small-craft applications relevant to this type: diesel exhaust and engine-room lagging, machinery gaskets and valve packing, and electrical insulation in the confined machinery space; the wood hull and small plant imply a substantially smaller asbestos footprint than a steam vessel.
