- Finding
- DANFS documents the full life cycle: laid down 16 November 1944 by Chicago Bridge & Iron Co., Seneca, IL, as LST-1126; launched 9 February 1945; departed Seneca 23 February 1945 via the Illinois and Mississippi rivers; commissioned at New Orleans 28 February 1945, Lt. F. C. Helm USNR commanding. Eight western-Pacific deployments 1945-1960 including postwar occupation service in China from late September 1945; three DEW Line resupply runs to Alaska (1949, 1950, 1953); named Snohomish County (LST-1126) 1 July 1955; 1962 MidPac cruise in support of Operation Dominic; Vietnam-era tours 1965, 1966, 1967 and an extended 1968-spring 1970 deployment including riverine operations in 1968; declared unfit after Inspection and Survey at Apra Harbor, Guam, April 1970; decommissioned and stricken 1 July 1970 at Naval Station Guam; sold January 1971 to Chin Ho Fa Steel and Iron Co., Ltd., Taiwan, for scrapping. Eight battle stars for Vietnam service. Spec block: dp. 4,080 (f.); l. 328'0"; b. 50'0"; dr. 14'1"; s. 11.6 k.; cpl. 119; a. 4 40mm; cl. LST-1081.

- Limitations
- Official Navy history; contains no asbestos, material-condition, or hazmat content. DANFS spec block's 'cl. LST-1081' is the BuShips design-group label for this hull block and coexists with the common 'LST-542 class' label carried by NavSource - a class-label granularity difference, not a contradiction. The INSURV survey itself is not published in this source.

- Finding type
- environmental_record
- Finding
- The Defense Nuclear Agency's official NTPR report names USS Snohomish County (LST-1126), 'tank landing ship with a normal complement of 119,' as an element of the Mobile Logistics Support Unit (TU 8.3.3) and Special Operations Unit (TU 8.3.9); a participation table lists her role as 'logistics' for the period January-August 1962. The per-ship narrative tabulates her position/status for ten shots (ADOBE, AZTEC, ARKANSAS, TANANA, TRUCKEE, OTOWI, BIGHORN - carrying 11 passengers toward Fanning Island - BLUESTONE, SUNSET, PAMLICO), including BLUESTONE (30 June 1962) anchored at Christmas Island about 36 nmi north of surface zero; she departed Christmas Island 24 July 1962. Ship-position figures also plot her among the anchored units off Christmas Island.

- Population
- Crew (normal complement 119 per this report); 11 passengers carried on the BIGHORN transit
- Limitations
- Documents ship participation, stationing, and duties in a nuclear test series - a radiological-environment record, not an asbestos record. The report gives ship positions and dose-reconstruction context but no individual crew doses for this hull and no statement about asbestos. OCR of the DTIC scan is imperfect (the ship-name string is occasionally garbled); the djvu text layer was the extraction source.

It establishes that deck logs exist for scanning, not any exposure finding - no asbestos or herbicide content.

[8]Consolidated era/design inference - NavSource-documented GM 12-567A diesel plant (no boilers) aboard this hull plus BuShips-era amphibious-ship construction practice for the LST-542 design family [other_primary]

- Consolidated inference row; mechanical specs corroborated by ev-02 (NavSource)
- Finding type
- asbestos_application
- Finding
- Era/design inference for a diesel-powered WWII LST: with no boiler plant, the steam-lagging pathway does not apply; era-typical asbestos applications aboard this design family were engine exhaust lagging and gaskets on the diesel exhaust runs, engine-room thermal and acoustic insulation, piping-system gaskets and valve packing, deck coverings/tile, bulkhead and accommodation insulation, and winch/crane brake linings. Interior rework across 25 years of service (including Vietnam-era maintenance) would have disturbed or renewed such materials at yard availabilities.

- Locator
- GAO HRD-80-2 product page, Highlights section
- Finding type
- gov_survey
- Finding
- GAO documented the Navy's asbestos-protection program: the 1975 policy removed and replaced asbestos insulation only when damaged or when removal was required for repairs, modified in 1979 to selective replacement in high-maintenance areas - meaning original-era insulation typically remained in place for decades across the fleet. Fieldwork for the report was conducted at Long Beach and Norfolk Naval Shipyards.

Product-page highlights were the access path this session (direct fetches to gao.gov have intermittently returned 403 to automated requests).

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or court record naming LST-1126 was found in the sources searched (see search_ledger). CourtListener searches returned zero hits for 'LST-1126' at both opinion and docket level; 'Snohomish County' asbestos queries returned only name-collision litigation (county government, MDL-875 master docket, unrelated civil matters) - no case naming the ship.
