- NavSource timeline for this hull: YMS-1 Class Auxiliary Motor Minesweeper laid down 8 May 1941 by the C. Hiltebrant Dry Dock Co., Kingston, NY; launched 8 October 1941; completed 10 June 1942; transferred to the Soviet Union 17 August 1945 and reclassified T-603; assigned to the (Soviet) Pacific Fleet 31 August 1945; placed out of service 1 September 1955 and laid up in reserve; reclassified BRN-14 27 February 1956; struck from the Navy list 25 June 1956; sunk in the Sea of Japan 28 June 1956 'in agreement with the United States.' Spec block: displacement 270 t.; length 136'; beam 24'6"; draft 8'; speed 15 kts.; complement 32; armament one single 3"/50 dual-purpose mount, two 20mm mounts, two depth-charge projectors; propulsion two 880bhp General Motors 8-268A diesels, Snow and Knobstedt reduction gear, two shafts. Commanding officers listed: LT J. W. Dowling, USNR (1945) and LT L. M. Shine, Jr., USNR (1945). Page states 'There is no DANFS history available for YMS-33.' uboat.net adds 'ordered 1 April 1941' and gives 10 June 1942 as the commissioning date; ShipbuildingHistory records the hull as a Mk. I YMS delivered 10-Jun-42 by Hiltebrant Dry Dock, Kingston NY, 'to the USSR (T603) 1945.'

- Limitations
- NavSource, uboat.net, and ShipbuildingHistory are reputable secondary compilations, not primary registries - milestone dates here are mutually consistent and the transfer milestone is confirmed by the official NHC Project HULA appendix (ev-02). Soviet-era milestones (out of service 1955, BRN-14, struck, sunk 28 June 1956) rest on NavSource alone among the sources cited, corroborated in outline by a Russian-language compilation (sewar.ru) in the search ledger. Spec conflicts across sources (displacement 270 vs 278/320 t.; engine rating 440 vs 880 bhp; speed 13 vs 15 kts.) are carried in gaps. No asbestos content in any of these sources.

- Finding
- Official U.S. Navy history documentation of this hull's transfer: the Project HULA appendix pairs 'YMS33' to Soviet designation 'T-603' with transfer date '17 Aug.' and disposition '1956-destroyed.' The book documents that the transfer program operated at Cold Bay, Territory of Alaska, that the planned roster included 36 wooden-hulled motor minesweepers (YMS) among 180 vessels, and that Navy Detachment 3294 transferred 149 ships to the Soviet navy in 142 days.

- Ship-specific on the transfer pairing, date, and disposal category (YMS-33 -> T-603, 17 Aug. 1945, '1956-destroyed'); 'destroyed' is the disposal class, not a cause or location - NavSource supplies 'sunk in the Sea of Japan 28 June 1956 in agreement with the United States.' The appendix does not state that YMS-33 was physically at Cold Bay, though all HULA transfers occurred there. No asbestos, materials, or condition content in the publication.

- Finding
- DANFS documents YMS-33's Pacific-war presence: on 19 November 1944 at Kossol Roads in the Palau group, the net-laying ship Winterberry (AN-56) reported sighting a submarine at 0858 while laying torpedo nets at the west entrance to the roadstead; the submarine 'submerged and surfaced three times in the space of two minutes and then moved off before YMS-33 belatedly got underway to investigate. That submarine probably was RO-37, which Conklin (DE-439) and McCoy Reynolds (DE-440) sank later that day about 20 miles north of the west entrance.'

- A mention of YMS-33 inside another vessel's DANFS entry - it places this hull at Kossol Roads, Palau, on a single date (19 Nov 1944) responding to a submarine contact; it does not identify the submarine with certainty ('probably was RO-37') and says nothing about YMS-33's other operations, condition, or materials.

- historical_record
- Finding
- NARA finding aid documents that logbooks for YMS-33 covering September 1, 1942 - August 16, 1945 exist in the custody inventoried by Special List 44: the entry reads 'YMS-33 Sept. 1, 1942-Aug. 16, 1945' followed by the list's logbook-count figure '10' (each SL44 entry 'includes the name of a vessel or shore establishment, the date span covered by the logbooks for that vessel or station, and the number of logbooks' per the list's Introduction). The coverage spans essentially her entire U.S. Navy career - from ~three months after her June 1942 completion to the day before her 17 August 1945 Soviet transfer. These logbooks are the primary-document lead for her 1942-44 Atlantic/Pacific movements (only the November 1944 Kossol Roads data point is otherwise documented) and for any materials/condition entries.

[6]Era inference built on: NavSource YMS-33 specifications (wooden-hulled YMS-1 class, twin GM 8-268A diesels, 2 shafts); Corn & Starr (1987) WWII shipbuilding asbestos documentation (ev-06); GAO HRD-80-2 Navy asbestos-era documentation (ev-07) [other_primary]

- Finding type
- asbestos_application
- Finding
- A wooden-hulled diesel-powered motor minesweeper completed in mid-1942 sits inside the Navy's documented asbestos-use era; era-standard applications aboard a small diesel craft of this type and period were thermal insulation around machinery and diesel-exhaust lagging, gaskets, valve packing, and electrical insulation. As a diesel vessel she carried no boilers or steam lines - the boiler/steam-line lagging pathway of steam vessels does not apply, and the era-typical asbestos load aboard a 136-foot wooden diesel craft was materially smaller than aboard steam-driven hulls.

Product names are normalized era terms; no manufacturer attribution for this hull. The wooden hull and diesel plant bound the inference - no steam-system products are inferred.

- Finding
- Peer-reviewed historical study documents that asbestos was used extensively as a fireproofing and insulating material in U.S. shipbuilding during World War II - the era and program under which this wooden-hulled motor minesweeper was built at a small civilian boatyard under Navy contract - and that wartime demand drove unprecedented asbestos utilization in vessel construction.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, insulation-material list, abatement contract, hazmat disclosure, or docketed case naming YMS-33 was found in the public sources searched (see search_ledger). No DANFS entry exists for this hull (NavSource states it; NHHC candidate URLs 404). The ship generated essentially no 'asbestos' footprint on the public web at all - the marketing-site sweep returned only the historical sources cited here, no law-firm listicles or untraceable figures requiring exclusion.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - a 1942 naval auxiliary is era-consistent with asbestos-containing materials regardless of hull material. The hull is sunk in the Sea of Japan since 1956, so no surviving-material survey is possible. Does not establish or defeat any claim of exposure or legal eligibility.
