- Finding
- NavSource's live hull page identifies USS Mahoning County as ex-USS LST-914, an LST-542-class tank landing ship laid down at Bethlehem Hingham Shipyard on 16 February 1944, launched 18 April 1944, and commissioned 18 May 1944. It records World War II southern-France and Okinawa campaign participation; decommissioning and striking on 26 June 1946; recommissioning at Yokosuka on 26 August 1950; the name Mahoning County effective 1 July 1955; final decommissioning at Long Beach on 5 September 1959; and sale for scrapping to Zidell Explorations Corp. on 22 June 1960.

- Bethlehem Hingham construction workers; U.S. Navy crew and maintenance personnel
- Limitations
- This is a hull history compilation, not a material survey or legal record. It does not document asbestos content, quantities, condition, removal history, individual exposure, causation, or legal eligibility. The page's 1946 line combines decommissioning and striking, whereas it gives no later strike date after the 1959 decommissioning; the latter is retained as unresolved.

- Locator
- Catalog search result titles include NAIDs 101766940 (War Diary, 7/1-31/45), 140033515 (War Diary, 5/1-31/45), 139965814 (War Diary, 3/1-31/45), 146207595 (LST-914 - January 1952), and 217184294 (Mahoning County - September 1959)
- Finding type
- historical_record
- Finding
- NARA's catalog returns ship-titled digitized record units for USS LST-914: war diaries for March, May, and July 1945 and monthly logbook units from January 1952 through April 1954; it also returns Mahoning County (LST-914) monthly units from March 1956 through September 1959. These are archival leads for ship operations and maintenance-era documentation.

- Limitations
- Catalog titles and dates establish digitized file-unit availability, not their contents. No underlying diary or logbook was reviewed for asbestos information, so this row makes no material, exposure, or causation finding.

- Locator
- Live page, LST-542 class and propulsion/specifications block
- Finding type
- asbestos_application
- Finding
- Class/era documentation only: LST-914's documented diesel LST-542 design provides context for prioritizing engine-room, exhaust, machinery, electrical, and deck-material records in future archival review. No source reviewed identifies an asbestos-containing application aboard this hull.

- Population
- Construction, engineering, deck-machinery, and maintenance populations; no exposure population established
- Limitations
- The design is a research-prioritization context only. It cannot establish that asbestos, or any particular insulation, gasket, packing, cable, covering, or friction material, was installed, retained, removed, or disturbed aboard LST-914/Mahoning County.

- search_ledger rows sl-uss-mahoning-county-lst914-01 through -06; CourtListener helper stderr: DAILY QUOTA EXHAUSTED, wait 28523 seconds
- Finding type
- historical_record
- Finding
- No qualifying ship-specific asbestos record was located in the public sources reviewed. The live hull page contains no asbestos, survey, abatement, hazmat, or material disclosure; NARA catalog metadata identifies logs and war diaries but does not state their contents. CourtListener litigation status is undetermined because the authenticated exact-name opinion request was stopped by a multi-hour daily-quota wait before a response; hull-number and docket requests were not made after that stop instruction.

- Limitations
- This is a negative finding about records located, not evidence that asbestos was absent. It makes no litigation-negative conclusion: CourtListener did not return an opinion result, and required hull-number and docket searches remain incomplete. It establishes neither exposure nor the absence of exposure, causation, or legal eligibility.
