- Finding
- NavSource identifies USS LST-615 as an LST-542-class tank landing ship laid down 4 February 1944 at Chicago Bridge and Iron Co., Seneca, Illinois; launched 9 May 1944; and commissioned 26 May 1944 with Lieutenant Loren L. Butler, USNR, in command. It records Asiatic-Pacific Theater assignment, the Leyte landings on 20 October 1944, the assault and occupation of Okinawa Gunto from 1-10 April 1945, Far East occupation service from 29 September-18 November 1945, decommissioning on 14 March 1946, striking from the Naval Register on 12 April 1946, and sale for scrapping on 7 April 1948 to Kaiser Co., Inc., Vancouver, Washington. It records two World War II battle stars.

- Finding
- NavSource reports LST-615 specifications of 328 feet overall length, 50-foot beam, 1,625 tons light displacement, 4,080 tons full-load displacement, 11.6 knots trial speed, 13 officers and 104 enlisted, and troop accommodations for 16 officers and 147 enlisted. It identifies two General Motors 12-567A 900-hp diesel engines, Falk main reduction gears, three diesel-drive 100-kW 230-volt DC ship's-service generators, two propellers producing 1,700 shp, and twin rudders.

- World War II discussion under 100 Years of Respiratory Protection History
- Finding type
- asbestos_application
- Finding
- NIOSH/CDC states that U.S. Navy asbestos use increased for pipe insulation as World War II began and continued after 1946. This provides era context for a 1944-built Navy vessel, but it does not identify material installed aboard LST-615.

- Finding type
- gov_survey
- Finding
- GAO's Navy asbestos review states that thermal insulation for machinery, equipment, and piping was a major Navy asbestos application and discusses gaskets, packing, and other shipboard uses. The review is program-level context and does not identify material aboard LST-615.

[7]National Archives, Researching Asbestos aboard US Naval Vessel up through 1961 [other_primary]
- Locator
- Beginning Research; Cartographic Branch; Other Records and their usefulness sections
- Finding type
- historical_record
- Finding
- The National Archives asbestos-research guide identifies Navy engineering drawings and related records as the principal route for determining whether a particular pre-1961 naval ship had asbestos material aboard, including hull-series material groups S39 (insulation and lagging) and S48 (piping). It also explains that deck logs and muster rolls do not directly establish asbestos presence.

- Limitations
- This is a research pathway, not a finding about LST-615. The cited guide does not say that this hull's S39, S48, or other engineering records contain asbestos information; no such records were retrieved for this batch.

[8]Batch-7134 source sweep: NavSource, NARA, GAO, NIOSH/CDC, NHHC/DANFS access attempt, and CourtListener helper attempts [other_primary]
- Locator
- Search-ledger rows sl-uss-lst-615-lst615-01 through -10
- Finding type
- historical_record
- Finding
- No ship-specific asbestos record was located in the accessible authoritative research: no asbestos survey, abatement contract, hazardous-material disclosure, insulation drawing, material schedule, or product identification naming LST-615 was found. This negative finding is limited by the unavailable DANFS text, unretrieved NARA records, and blocked CourtListener sweep.

- Limitations
- Failure to locate a public record does not prove absence of asbestos aboard. This is an access- and coverage-limited negative finding, not evidence that the hull was asbestos-free and not evidence that an exposure claim is defeated.
