- Limitations
- Inventory-level finding only: SL44 documents that deck logs exist for this hull and their date span; it does not state their content, and the logs themselves are not digitized. Log coverage is not a commissioning/decommissioning certificate - the 11 Sep 1943 commissioning and 16 Aug 1945 out-of-commission dates are carried from NavSource and the hull's own war diary respectively. No asbestos content.

- War-diary-documented service aboard this hull: December 1943 - minesweeping practice in the San Pedro-Santa Barbara area with AM-154, YMS-302, and YMS-387; serving as training platform for YMS-396 officers and a YMS-296 precommissioning crew at the Small Craft Training Center, San Pedro, and Section Base, Santa Barbara. By June 1944 operating from Majuro Atoll under CTU 57.7.3 - entrance-patrol duty alternating with YMS-263 (relieving USS Captivate AM-156 and USS Capable AM-155), channel sweeping for moored mines with YMS-263, and Majuro-Kwajalein convoy-escort runs (USS Cheleb AK-138, USAT Yarmouth, ATR-44 with YOG-183 in tow, YW-88). September 1944: Majuro duties of CTU 57.6.3 - minesweeping drills in Majuro Lagoon with YMS-299 and YMS-263, streaming 'O' type and magnetic gear; harbor entrance patrol. November 1944: departed Seeadler Harbor, Manus Island, Admiralty Islands 1 Nov for Majuro, arrived 7 Nov; 24-30 Nov alongside USS Howard W. Gilmore (AS-16) for emergency repairs. December 1944-January 1945: convoy-escort duty eastward in company with YMS-195, -263, -262, -242, guarding SS La Placentia; La Placentia detached for San Francisco 7 Jan 1945; YMS-301 entered San Pedro harbor 9 Jan 1945 and de-ammunitioned 'preparatory to entering Harbor Boat Building Co.'

- War-diary-documented 1945 repair, overhaul, and transfer events aboard this hull: 'the entire month of February this vessel was undergoing an extensive overhaul at the Harbor Boat Building Company, San Pedro, California' (Feb diary; overhaul began ~10 Jan 1945 per Jan diary). April-May: assigned to ComPhibsTraPac San Diego under Commander Shakedown Group - target towing for shakedown gunnery (DD-857 USS Bristol, USS Rowan, USS Strong, USS Huntington, USS Floyd Bay, USS Vella Gulf among ships firing) and ASW exercises (SS-184, AM-316, PCE-882, ATF-117, West Coast Sound School). June: 'assigned to special board Com Thirteen' - moored Pier 90, U.S. Naval Station Seattle 1-29 June 'necessary repairs being accomplished'. July: 'ship under special program assigned to ComThirteen' - Puget Sound mine-sweep trials 1 July; collision entering slip with Coast Guard Cutter 45 and YMS-100; alongside Bellingham Iron Works, Bellingham, Washington for repairs 2-14 July; depermed at Bremerton degaussing station 15 July; departed Seattle 23 July for Alaska via the Inside Passage (Ketchikan 26 July); arrived Kodiak 30 July. August: Kodiak to Cold Bay 2-4 Aug; daily underway training exercises 7-13 Aug 'with own nucleus crew and thirty-odd trainees'; 'at 1700 [16 Aug] vessel placed out of commission' at Cold Bay.

- Limitations
- Documents named repair and overhaul events aboard this hull - the maintenance-disturbance pathway for era materials - but no diary states the materials handled; nothing here establishes asbestos content, quantity, or fiber release. 'Special program assigned to ComThirteen' is the ship's own contemporaneous framing for its Project Hula assignment (Hula was secret; the program name does not appear in the diaries). Harbor Boat Building Co. (San Pedro), Bellingham Iron Works (Bellingham WA), and Naval Station Seattle repair activity are documented events; the specific work performed is not detailed in the diaries.

[6]Russell, Richard A., 'Project Hula: Secret Soviet-American Cooperation in the War Against Japan' (Naval Historical Center, Washington DC, 1997) - transfer appendix and Soviet-service narrative (HyperWar/ibiblio mirror of the NHHC monograph) [other_primary]

- Finding
- The NHHC monograph's transfer appendix lists this hull by name: 'YMS301 - T-605 - 17 Aug. - 1955-stricken*' with the footnote '* subsequently transferred to the Peoples Republic of China.' The monograph documents that 36 wooden-hulled motor minesweepers were programmed for the secret Cold Bay, Alaska transfer program (Navy Detachment 3294, ~12,000 Soviet personnel trained), and that 'under Soviet colors, the wooden-hulled YMSs performed a variety of combat, auxiliary, and scientific tasks... all were decommissioned by the mid-1950s.' Sources cited for the appendix: Ships Data: U.S. Naval Vessels vol. II (NAVSHIPS 250-012, 1949) and Berezhnoi, Flot SSSR (1994).

- Official U.S. Navy history publication - the authoritative US-side account of the transfer program. The appendix dates YMS-301's transfer 17 Aug 1945; the ship's own war diary places it out of commission at 1700 on 16 Aug 1945 - adjacent events, not a conflict (decommission vs. flag transfer). The appendix's '1955-stricken' refers to the Soviet Navy list; the precise US Naval Vessel Register strike action for this lend-lease hull is not stated. No asbestos content.

- NavSource timeline for this hull: laid down 14 November 1942 by William F. Stone and Son, Oakland, CA; launched 1 May 1943; completed 11 September 1943 and commissioned USS YMS-301; transferred to the Soviet Union 17 August 1945 and reclassified T-605; assigned to the (Soviet) Pacific Fleet 31 August 1945; transferred to the People's Republic of China 11 February 1955 and struck from the Soviet Union Navy list; 'fate unknown.' Specifications: displacement 270 t.; length 136'; beam 24'6"; draft 8'; speed 15 kts; complement 32; armament one 3"/50 dual-purpose mount, two 20mm mounts, two depth-charge projectors; propulsion two 800 bhp General Motors 8-268A diesel engines, Snow and Knobstedt single-reduction gear, two shafts. Call sign Nan-Peter-How-Charlie. uboat.net independently carries the same milestone dates plus an order date of 27 March 1942. NavSource explicitly notes no DANFS history exists for this hull - consistent with NHHC DANFS page returning 404.

The 27 March 1942 order date rests on uboat.net alone (secondary). Specifications are class-standard figures for YMS-1 type. Contains no asbestos content.

- Finding type
- asbestos_application
- Finding
- A wooden-hulled, diesel-powered motor minesweeper built 1942-43 sits inside the documented Navy asbestos-use era. There is no steam plant - the boiler/turbine lagging pathway of steam vessels does not apply - but era-standard asbestos applications aboard a diesel-driven small combatant of this period were: engine and exhaust-manifold/muffler insulation, machinery-space lagging, gaskets (engine, piping, flange), valve and machinery packing, electrical insulation, and winch/windlass brake linings. The type carried a dedicated diesel generator for magnetic minesweeping plus auxiliary diesels - additional machinery insulation surface in a confined 136-foot wooden hull.

Names era-standard applications, not confirmed installed materials; wooden-hulled motor minesweepers carried materially less insulation than steam vessels. No quantity; no manufacturer attribution for this hull.

CourtListener 'YMS-301' base queries completed on both indexes - opinion (84 hits) and docket (6,815 hits), every page-1 hit classified as a name collision with no vessel or asbestos context; 'USS YMS-301' base queries and the asbestos-qualified variants were paced out (fleet-wide ~58/hr budget spent) and are logged as blocked in search_ledger, not as a negative result. Secondary web sweeps surfaced no qualifying case and no law-firm marketing page even asserting asbestos aboard this specific hull.

- Absence of a located public record does not prove absence of asbestos aboard - era-consistent materials were standard for the type. The 'USS YMS-301' base queries and asbestos-qualified variant sweep are a genuine open gap (paced, not run); completed base queries show collision-only noise, not asbestos-qualified results. Deck logs (RG 24 Entry 118), Harbor Boat Building and Bellingham Iron Works work orders, and any Soviet/PRC-era records are undigitized leads. Does not establish or defeat any claim of exposure or legal eligibility.
