[2]LST-12 DANFS transcription; current NHHC page checked but returned 404, so the live transcription is cited as the accessible copy and the gap is recorded. [nhhc_danfs]

- LST-12 entry in the LST-7 through LST-12 section
- Finding type
- vessel_history
- Finding
- DANFS transcription records that LST-12 was laid down on 16 August 1942 at Pittsburgh, Pennsylvania, by Dravo Corporation; launched on 7 December 1942; sponsored by Mrs. Joseph Fay; transferred to the United Kingdom on 25 March 1943; returned to U.S. Navy custody on 5 January 1946; struck from the Navy list on 20 March 1946; and sold for scrapping on 11 September 1947 to Washburn Wire Co., Phillipsdale, Rhode Island.

- The source is a live transcription of the DANFS entry, not the current NHHC-hosted page; NHHC's current LST-12 URL returned 404. It supports the listed identity and disposition facts, not asbestos content, individual exposure, or causation.

- Finding type
- vessel_history
- Finding
- The Royal Navy record identifies HM LST-12 as an LST(2)-type tank landing ship built by Dravo Corporation at Pittsburgh, laid down 16 August 1942, launched 7 December 1942, commissioned 26 March 1943, and paid off on 5 January 1946 before return to U.S. custody. The accessible record also identifies the former U.S. name as LST-12.

- This is an authoritative-history lead rather than a current Navy registry page; it corroborates Royal Navy service dates and former name. It contains no asbestos information and does not establish a U.S. Navy commission for this hull.

[4]Bureau of Ships, Ships' Data, U.S. Naval Vessels, Vol. 2 (January 1945), LST design table [other_primary]
- Locator
- LST design table and LST roster
- Finding type
- historical_record
- Finding
- Official Bureau of Ships design data for the LST group specifies two General Motors 12-567A diesels, approximately 1,700 shaft horsepower, about 11.6 knots, and accommodations of 13 officers and 106 enlisted. This supports the design description used for LST-12; it does not verify the hull's actual crew complement or any hull-specific material installation.

[5]Conservative synthesis from BuShips LST design data and the 1942-1945 Navy asbestos-use-era context; no hull-specific asbestos document located [other_primary]
- Locator
- LST design table; class-profile era analysis
- Finding type
- asbestos_application
- Finding
- Era/design inference: a 1942 diesel-powered LST could have asbestos-relevant materials in diesel or exhaust insulation, gaskets and packing, deck coverings, accommodation or bulkhead insulation, and winch or windlass brake linings. The diesel configuration means boiler and steam-lagging pathways are not supported by the class design record.

- search_ledger rows sl-uss-lst-12-lst12-01 through sl-uss-lst-12-lst12-09
- Finding type
- historical_record
- Finding
- No qualifying ship-specific asbestos record was located in the public sources searched: no asbestos survey, material schedule, abatement contract, hazmat disclosure, or qualifying litigation record naming LST-12 or HM LST-12 was found. The accessible DANFS transcription and Royal Navy history contain no asbestos statement.

- Limitations
- A negative public-source search does not prove that asbestos was absent aboard a 1942 hull. CourtListener exact-name docket coverage was interrupted by the fleet pacing limiter, so the litigation negative is not exhaustive; no result located is not a merits finding and does not establish or defeat exposure or legal eligibility.
