- Finding
- Documented for this hull: laid down 29 September 1938 at Vallejo, Calif., by the Mare Island Navy Yard; launched at midnight on 3 May 1939 'via an aerial route' - large cranes hoisted her from her building ways, swung her over the water, and lowered her into the channel; completed 23 June 1939 and subsequently commissioned. Performed towing and fire-fighting duties in the Twelfth Naval District throughout World War II; redesignated medium harbor tug YTM-134 on 15 May 1944; declared surplus and stricken from the Navy List 30 December 1946; transferred to the Maritime Commission 2 June 1947 for disposal. Commercial chain (DANFS, updated 2022): acquired 1947 by Curtis Bay Towing, Baltimore, renamed C. Stewart Lee; purchased by Bay Towing Co., Norfolk, renamed Bay Prince in 1971; renamed Marie Swann in 1998 under Indian River Towing Co., Wilmington, Delaware. Spec block: dp. 250; l. 100'0"; b. 25'0"; dr. 10'0". Second USN ship named for Waneta, Yanktonai Sioux (1795-1848).

Dimension figures conflict with NavSource on length and draft (see gaps). DANFS records stricken 30 December 1946; the decommission date comes from NavSource.

- Finding
- Photographic and operational records held at NARA place this hull's existence and activity: the DANFS caption credits Bureau of Ships photo 19-LCM-20754 (Wahneta underway near Mare Island, 21 June 1939); NavSource captions credit Mare Island Navy Yard photos 952-39 (21 June 1939, pre-commissioning) and 7015-45 (9 November 1945, broadside with USS Missoula APA-211 in dry dock #3). The COM 12 (Commandant, Twelfth Naval District) war diary for Dec 1941-Mar 1942 covers the command the tug served under during the Pearl Harbor-era opening of her WWII service. These are leads for construction and wartime-presence documentation, not work or material records.

- Finding type
- asbestos_application
- Finding
- A diesel-electric yard tug built 1938-39 at a U.S. Navy yard sits inside the documented Navy-wide asbestos-use era: GAO recorded thermal insulation as the Navy's major asbestos use aboard ships, with substitution of nonasbestos materials not beginning until the early 1970s - spanning this hull's entire construction and service period. Era-standard applications aboard a small diesel-electric craft of this period were engine and generator exhaust lagging, gaskets, valve packing, and electrical/cable insulation. As a diesel-electric vessel she carried no steam plant - the boiler/turbine lagging pathway of steam vessels does not apply.

[6]Department of the Navy / City of Vallejo, Final Environmental Impact Statement/Environmental Impact Report for the Disposal and Reuse of Mare Island Naval Shipyard (April 1998; DTIC accessions ADA344388/ADA344389, SCH# 94093029) - asbestos section 3.13.4 and impact analysis (City of Vallejo-hosted copy verified 2026-10-05; apps.dtic.mil under maintenance) [other_primary]

- Finding type
- environmental_record
- Finding
- The Navy's own disposal-reuse EIS/EIR for this hull's builder documents asbestos-containing material at Mare Island Naval Shipyard: Section 3.13.4 (Asbestos, p. 3-190) treats ACM in shipyard buildings and structures; the impact analysis notes that 'a number of buildings and residential structures with ACM would be demolished or renovated' under reuse alternatives; and the utilities discussion expressly describes 'abating asbestos in cable insulation' as part of system upgrades. DoD policy cited in the document is that 'property with ACM will not be disposed (of) through the BRAC process unless it is determined that the ACM does not pose a threat to human health at the time of transfer.'

- Limitations
- Yard-level facility documentation, not a vessel record: the EIS covers buildings, structures, and utility systems on the island - it does not document asbestos aboard any vessel built or serviced there, and does not name YT-134. It establishes that the yard operated within an asbestos-materials environment, which contextualizes but does not prove hull content.

- GAO HRD-80-2 transmittal letter and 'Navy's Policy on Use of Asbestos' section (full text via gao.gov/assets/hrd-80-2.pdf)
- Finding type
- gov_survey
- Finding
- GAO documented that 'although all ships contain some asbestos in such components as clutches and electric cables, most ships delivered in the last several years or now under construction have little or no asbestos as thermal insulation, which was the Navy's major use of asbestos aboard ships.' The Navy's policy to eliminate asbestos use where suitable alternates existed was issued October 1975; removal was limited to damaged insulation or insulation requiring removal for repairs, expanded in 1979 to selective replacement in high-maintenance areas. Asbestos thermal insulation and component use therefore spans this hull's entire construction (1938-39) and service era (1939-46).

- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, build-specification material list, or verified litigation naming USS Wahneta (YT-134/YTM-134) was found in the public sources searched (see search_ledger). CAVEAT: CourtListener could not be queried this session - every authenticated request returned the fleet-wide pacing block; logged as blocked in search_ledger, not as a negative result. Secondary web sweeps surfaced no qualifying case and no law-firm ship-page coverage naming this hull.

NARA RG 24 deck logs, Mare Island hull/build-way work orders, and any Maritime Commission disposal file are undigitized leads. Does not establish or defeat any claim of exposure or legal eligibility.
