- Finding
- NavSource identifies this hull as YMS-332, a YMS-1-class auxiliary motor minesweeper that 'served the Navies of the United States, the Soviet Union and the People's Republic of China.' Timeline: laid down 3 March 1943 by the Ballard Marine Railway Co., Inc., Seattle, WA; launched 5 June 1943, sponsored by 15-year-old Miss Jo Ann Eaton; completed 12 October 1943; transferred to the Soviet Union 6 September 1945 and reclassified T-607; assigned to the Pacific Fleet 5 September 1945; transferred to the People's Republic of China 11 February 1955; '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 880bhp General Motors 8-268A diesel engines, Snow and Knobstedt single reduction gear, two shafts.

- Limitations
- NavSource is a volunteer secondary compilation, not a primary registry, and does not document asbestos content. The '6 September 1945' transfer date conflicts with the official NHC Hula appendix (27 Aug., ditto) and the Soviet-side acceptance date (26 Aug.) - the conflict is carried in ev-11 rather than resolved here. 'Assigned to the Pacific Fleet 5 September 1945' matches sewar.ru's 5.09.1945 arrival at Petropavlovsk-Kamchatsky (Soviet Pacific Fleet), which makes a 6 Sep U.S. transfer date internally inconsistent - a physical handover must precede arrival. Spec figures conflict with the class index (270t/32/15kts here vs 320t/33/12kts designed - see gaps).

- NARA Special List 44 inventories deck logs held for YMS-332 covering 10/12/1943 - 6/30/1945 (RG 24, National Archives at College Park). The coverage window opens on her completion/commissioning date (12 October 1943) and closes 30 June 1945 - about two months before her Project Hula transfer; these are log-coverage dates, not asserted commissioning or transfer dates. YMS-332 does not appear on NARA's list of digitized deck logs available in the National Archives Catalog (the digitized YMS entries are the hulls later named under the AMS program); the logs are an undigitized primary record spanning most of her U.S. commission.

- Finding type
- vessel_history
- Finding
- Official Navy-published transfer record names this hull: the HULA appendix lists 'YMS 332 - T-607' as the last row of the motor-minesweeper transfer list, with ditto marks in the Transfer Date and Disposition columns carrying forward '27 Aug.' and '1955-stricken*' - the footnote reading '* subsequently transferred to the Peoples Republic of China' (row verified on printed page 40 / PDF page 45, rendered page image). The monograph establishes that Cold Bay, Alaska (Fort Randall) was the single transfer point, that 149 U.S. Navy vessels were transferred there April-September 1945 with Soviet crews trained by Navy Detachment 3294, that 36 wooden-hulled motor minesweepers were programmed for the program, 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).

- The operations-history compilation places this hull's transfer in a dated group: 'On 26 August the transfers comprised the frigates Bisbee, Gallup, Bickford, Muskogee, Carson City and Burlington, and on the next day [27 August] the motor minesweepers YMS-88, YMS-180, YMS-135, YMS-332 and YMS-285.' This names YMS-332 in the 27 August 1945 transfer group at Cold Bay - convergent with the official appendix's ditto-marked 27 Aug. date and with sewar.ru's 26 August Soviet-crew acceptance, and conflicting with the NavSource/uboat.net 6 September date.

- Soviet-side record for this hull (translated): 'Laid down 3.03.1943 (Seattle, USA), launched 5.06.1943, commissioned 12.10.1943. 26.08.1945 accepted by the Soviet crew under lend-lease deliveries. 5.09.1945 arrived Petropavlovsk-Kamchatsky and entered the TOF [Pacific Fleet]. 11.02.1955 struck from the Soviet Navy list in connection with transfer to the People's Republic of China Navy.' The page title 'T-607 (until 28.05.1945 "YMS-332")' carries the standard 28 May 1945 designation date used across the transferred-YMS records. The 26 August acceptance and 5 September arrival are mutually consistent with the official 27 August transfer date and inconsistent with a 6 September handover - the hull arrived in Soviet waters under Soviet flag the day before the NavSource/uboat.net transfer date.

The surrounding log describes Bering Sea cable-laying among the Aleutian islands (Attu, Kiska, Shemya, Adak, Dutch Harbor) in early 1944.

- Published secondary literature places T-607 in Soviet service at Port Arthur in the late 1940s: the base's water-area protection force (OVR, under Capt. 3rd Rank A. Kaduchenko) included the '18th separate minesweeper division' of six YMS-type ships - T-605, T-606, T-607, T-608, T-609 and T-611 - based in the West Basin of the harbor. T-607 is this hull; the other five are her Cold Bay transfer-group sisters (YMS-301, YMS-135, YMS-88, YMS-180, YMS-287 respectively).

- CORRECTION: the builder's production table lists YMS-332 as US Navy minesweeper, 278d tons, 136 ft., delivered 12-Oct-43, disposition 'To the USSR 1945 as T-611, scrapped 1956.' The T-611 is a documented error: the official NHC Hula appendix assigns T-611 to YMS-287 and T-607 to this hull, and the Naval Marine Archive master table, NavSource, sewar.ru, and shipindex.org all carry this hull as T-607. Record carried: Soviet designation T-607. The row's 'scrapped 1956' disposition is likewise unverified - it conflicts with the documented 11 February 1955 transfer to the People's Republic of China (appendix stricken* footnote + sewar.ru + NavSource) and NavSource's 'fate unknown'; carried in gaps, not asserted. The yard-history header records that Ballard Marine Railway was a significant small shipyard from the 19th century through WWII, taken over in 1946 by Pacific Fishermen.

Record carried: transferred to the Soviet Union 27 August 1945, with the 6 September variant preserved here as a documented conflict rather than silently resolved.

- Finding
- A wooden-hulled diesel-powered small craft of 1943 construction sits inside the Navy's documented asbestos-use era, but the exposure surface is materially smaller than a steam vessel's: no boilers, no steam drums, no steam-line lagging. Era-standard applications aboard a minesweeper of this type and period were diesel exhaust lagging and silencer insulation, engine and machinery insulation, flange gaskets, valve packing, electrical insulation, brake linings on winch/windlass gear, and incidental fireproofing - compact quantities concentrated in the small engine-room volume.

- Finding
- NARA's official research guide says documenting asbestos aboard a particular U.S. naval vessel requires layered research and identifies RG 19 Bureau of Ships correspondence (filed by hull designation and by shipyard - a private yard like Ballard Marine Railway would be filed under 'QM'), minesweeper/minelayer General Information Books, specifications, and hull engineering drawings as potential sources. It also explains that deck logs and muster rolls do not directly establish asbestos presence or material content.

- Limitations
- This is a research pathway, not a YMS-332 material record. The cited RG 19 series were not retrieved or examined; the guide neither proves nor disproves asbestos aboard this hull.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, product identification, VA/BVA decision, or docketed case naming USS YMS-332 or T-607 was found in the public sources searched (see search_ledger). This is consistent with the hull's profile - a small wooden minesweeper built at a wartime small-craft yard, transferred abroad in 1945 with no post-service physical existence under U.S. jurisdiction to survey or abate. The only 'asbestos aboard' material for YMS-class hulls is law-firm marketing listicle content asserting asbestos without primary sourcing - excluded by source policy.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - era-consistent inference still stands, and small-craft records are thinly digitized. CourtListener status is as logged in the search_ledger: the exact-name opinion query completed with zero hits, while the docket and hull-number queries were stood down by the fleet pacing limiter - a blocked or partial sweep is an access gap, not a negative result. Undigitized deck logs (RG 24), uncataloged war diaries (RG 38), muster rolls (RG 24), and RG 19 builder correspondence remain open leads. Does not establish or defeat any claim of exposure or legal eligibility.
