- DANFS (NHHC, verified live): LST-724 was laid down 20 July 1944 at Jeffersonville, Ind., by the Jeffersonville Boat & Machine Co.; launched 29 August 1944, sponsored by Mrs. Frances M. Lively; commissioned 22 September 1944; assigned to the Asiatic-Pacific theater and participated in the assault and occupation of Okinawa Gunto April-June 1945; postwar occupation duty in the Far East and China service until late March 1946; decommissioned 26 June 1946; struck from the Navy list 31 July 1946; sold 23 September 1947 to William E. Skinner, New York, N.Y. DANFS text prints 'one battle star for World War II service' - in conflict with the NavSource campaign table (see ev-02 and gaps).

The DANFS text does not mention the Iwo Jima operation or the 31 March 1945 kamikaze damage - those rest on the NHHC image caption, NavSource, and Cressman (other rows). DANFS 'one battle star' conflicts with NavSource 'two' - conflict carried in gaps. Contains no asbestos information.

Trucks at the right are towing 105mm howitzers inland from LST-724.' The NavSource photographic record corroborates and extends this: LST-724 moored at Naval Station Pearl Harbor between 8 December 1944 and 22 January 1945 undergoing training during the build-up for Operation Detachment (W. Eugene Smith photo); beached at the foot of Mount Suribachi 24-25 February 1945 (US Navy photos S-193-1, S-193-A2); unloading across the beach with LST-84 on D+11, 2 March 1945 (US Navy photo COMBPHIBGTP2); on the beach at Okinawa and at Buckner Bay into early 1946; and moored pierside at San Francisco Naval Shipyard, Hunters Point, 24 June 1946 while being prepared for storage as part of the reserve fleet.

- NARA NAID 74252365 resolves live to 'World War II - Okinawa' in Records of the U.S. Marine Corps (local ID 127-GR-107-126987). Per the NavSource caption transcription of this NARA photo: 'Iheya Landing - Landing craft loaded with the Eighth Marine Regimental Combat Team, stand offshore as an aerial bombardment paves the way for a landing on Iheya, a small island 25 miles northwest of the northern tip of Okinawa. The unopposed thrust was effected 3 June 1945. The Marines were transported to Iheya by Navy LSTs including LST-747, LST-724 and LST-930.'

- Finding type
- asbestos_application
- Finding
- Era/design inference for a diesel-powered LST-542-class hull: no boilers, so no boiler or steam-line lagging pathway; asbestos-relevant applications aboard the type were diesel exhaust lagging and gaskets, engine-room thermal/acoustic insulation, deck coverings and tile, bulkhead and accommodation insulation, and winch/crane brake linings. The LST program was the Navy's largest WWII ship class, mass-produced 1942-1945 at 17 yards including the inland 'cornfield' yards such as this hull's builder; LSTs of the era were unnamed and county names were assigned 1 July 1955 only to hulls still in service - this hull was sold in 1947 and never named.

- Finding
- Peer-reviewed historical study documents that asbestos was used extensively as a fireproofing and insulating material in U.S. shipbuilding during WWII - the era and emergency mass-production program under which this LST-542-class hull was built - and that wartime demand drove unprecedented asbestos utilization in ship construction.

- GAO HRD-80-2 product page
- Finding type
- gov_survey
- Finding
- GAO documented the Navy's asbestos-protection program: asbestos insulation was installed in Navy ships from the WWII era onward, and standing policy (1975) removed it only when damaged or required for repairs, modified 1979 to selective replacement in high-maintenance areas - meaning original-era insulation typically remained aboard in-service hulls for decades.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or docketed litigation naming LST-724 was found in the public sources searched (see search_ledger). The hull left government custody 23 September 1947, decades before the Navy's documented asbestos-abatement era, so no in-service abatement record exists to find; post-sale disposition is unknown.
