- Finding type
- historical_record
- Finding
- The official Coast Guard war history documents 'Coast Guard manned LST-207' in four combat episodes: (1) Empress Augusta Bay, Bougainville, 17 November 1943 - while in the convoy in which APD McKean was torpedoed, LST-207 opened fire at about 0337 on an enemy 'Betty' bomber at roughly 400 yards and was credited with bringing down two Bettys, firing on two additional planes with unknown results; (2) Saipan convoy, 17 June 1944 - she engaged attacking torpedo planes, one of which launched a torpedo that struck LCI-468, and debris from the explosion wounded a Marine aboard LST-207 who later died; (3) Guam assault, 15-28 July 1944 - departed Eniwetok 15 July with Tractor Group Three, discharged all 17 embarked LVTs (including four armored amphibious tanks) within six minutes of reaching the launching area off Asan Beach on 21 July, beached 24 July to unload vehicles and cargo, sustained no damage from four Japanese mortar bursts landing about 800 yards distant on the 26th, and departed for the Marshall Islands on the 28th; (4) Leyte, October 1944 - departed Manus 4 October as part of Task Group 79.1, entered Leyte Gulf 20 October, unloaded at Violet Beach #2 and Yellow Beach #2, and fought repeated air attacks on 25-26 October with hits observed on multiple aircraft (one 'Val' crashing on the beach).

- Finding type
- asbestos_application
- Finding
- The U.S. Coast Guard's own health-services documentation acknowledges asbestos aboard Coast Guard-manned vessels of this hull's construction era: the Office of Health Services (CG-112) page instructs that personnel 'assigned to Coast Guard cutters that were constructed prior to 1991 ... may have been exposed to very low levels of asbestos,' identifying 'asbestos-containing thermal insulation' and 'asbestos-containing floor tiles' as routine exposure sources aboard cutters, and ALCOAST 364/17 (December 2017, 'Medical Documentation of Asbestos and Lead Exposures on Coast Guard Cutters,' superseded/updated by ALCOAST 090/18) directs entry of exposure documentation into service treatment records to support VA disability claims. LST-207 was built 1942-43 and manned throughout by a U.S. Coast Guard crew - within both the service acknowledged and the pre-1991 construction window.

- Population
- Coast Guard members assigned to pre-1991 cutters (service-level); by inference, this hull's USCG crew (1943-46)
- Limitations
- Service-level documentation - names no individual hull. Written for 'Coast Guard cutters'; LST-207 was a Navy-owned USS hull with a Coast Guard crew, so inclusion rests on the manning service and construction era, not on the hull being cataloged - the linked cutter list (vessels in service 1990-2017) cannot include a ship decommissioned 1946. Establishes era-consistent asbestos products aboard Coast Guard-manned vessels generally; does not establish presence, quantity, condition, or any individual exposure aboard this hull.

- Finding
- Peer-reviewed historical scholarship documents that asbestos was used extensively for fireproofing and insulation in U.S. shipbuilding during World War II - the program and era under which this 1942-43 hull was mass-produced at the Seneca 'Prairie Shipyard' - and that wartime naval construction drove unprecedented asbestos utilization aboard hulls of this type.

- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, museum documentation, or litigation naming LST-207 was found in the public sources searched (see search_ledger). CourtListener API v4 returned zero results for both spellings ('LST-207' and 'LST 207') across opinion and RECAP docket indexes (four authenticated queries, all HTTP 200, count 0) - a clean negative, not a blocked search. VA Board of Veterans' Appeals opinion searches returned no decision naming this hull.

- Absence of a located public record does not prove absence of asbestos aboard - class/era documentation makes asbestos presence plausible but unproven for this hull. The hull was scrapped in 1947-48; no extant fabric exists to survey. Does not establish or defeat any claim of individual exposure or legal eligibility.

- Finding
- Flotilla-level primary records survive as image-only scans: NavSource hosts NARA-derived LST Flotilla Five war-diary PDFs for May and July 1944 (the July 1944 volume covers the Guam operation in which this hull participated per the official Coast Guard history). The files are un-OCR'd page images (~14 MB), so a ship-specific mention within them is not text-verified. NARA RG 24 deck logs for this hull and the flotilla war diaries in original form are not digitized in the public catalog.
