- Finding
- NavSource records LST-923's Asiatic-Pacific service, including the Lingayen Gulf landing on 9 January 1945 and the assault and occupation of Okinawa Gunto from 2 April through 18 June 1945; it then records Far East occupation-service periods from 2 September to 28 October 1945 and 9 November 1945 to 10 April 1946, followed by decommissioning on 9 July 1946, striking on 15 August 1946, and sale for scrapping on 31 May 1948 to Bethlehem Steel Co.

- Population
- Navy crew, occupation-service personnel, and Bethlehem Steel scrapping workers
- Limitations
- NavSource gives 9 July 1946 for decommissioning; the NHHC DANFS search result gives 10 July 1946. The conflict is carried rather than silently resolved. No asbestos or material finding follows from this history.

[3]NavSource Online, USS LST-923 specifications [museum_official]

- Live page, Specifications section
- Finding type
- historical_record
- Finding
- NavSource's specifications identify this hull's 328-foot length, 50-foot beam, trial speed of 11.6 knots, 7-officer/104-enlisted complement, troop accommodations for 16 officers and 147 enlisted, and four LCVP boats. The same page identifies two General Motors 12-567A 900-hp diesel engines, Falk main reduction gears, three diesel-drive 100-kW 230-V DC ship-service generators, two propellers, and 1,700 shaft horsepower.

- The specifications establish the propulsion arrangement and crew figures but do not establish that any insulation, gasket, packing, cable, covering, or friction material aboard this hull contained asbestos.

[4]U.S. General Accounting Office, Navy Efforts To Protect Workers From Asbestos Exposure, HRD-80-2 [gao]
- Locator
- Report introduction and Navy policy/use sections, pp. 1-3
- Finding type
- asbestos_application
- Finding
- Era/program context: GAO reported that Navy ships contained some asbestos in components such as clutches and electric cables, and that thermal insulation was the Navy's major shipboard asbestos use. Applied cautiously to LST-923's 1944 diesel design, this supports only a class/era inference that machinery or exhaust insulation, gaskets, packing, electrical materials, deck coverings, accommodation materials, and brake/friction linings were plausible asbestos-relevant applications.

- Population
- 1944 shipyard trades, Navy engineering and deck-maintenance personnel, and 1948 shipbreakers
- Limitations
- Program-level evidence, not a record for LST-923. It does not identify materials aboard this hull, product manufacturers, quantity, condition, removal history, individual exposure, or causation. Diesel-specific application list is an inference from the documented machinery and common shipboard material pathways, not a confirmed installation list.

[6]Batch-7466 source review and search ledger: NavSource, NARA Special List No. 44, GAO HRD-80-2, and authenticated CourtListener helper attempts [other_primary]
- Locator
- search_ledger rows sl-uss-lst-923-lst923-01 through -09
- Finding type
- historical_record
- Finding
- No qualifying ship-specific asbestos record was located in the public sources searched: NavSource's hull page contains no asbestos, survey, abatement, hazmat, or insulation-material disclosure; NARA's logbook index is only a finding aid; and the authenticated CourtListener sweep was stopped by the server-requested daily quota stand-down before a result could be obtained.

- Limitations
- This is a finding about records located, not proof that asbestos was absent. CourtListener coverage is incomplete because the authenticated helper reported the daily quota exhausted; no litigation conclusion should be drawn from that gap. The 1944 construction era remains consistent with possible asbestos-containing materials, but presence aboard this hull is not ship-proven.

- NavSource's hull history identifies LST-923 as an LST-542-class tank landing ship laid down on 3 May 1944 at Bethlehem-Hingham Shipyard, Hingham, Massachusetts; launched 11 June 1944; and commissioned as USS LST-923 on 6 July 1944 under Lt. John T. Gordon, USN.
