- NavSource is a volunteer secondary compilation, not a primary registry - its milestone dates track DANFS here and the unit assignment is independently confirmed by the NHHC fleet-organization document (ev-03). Contains no asbestos content. CO roster is credited to private researchers (Hechler/Reeves), not an official roster. 'Fate unknown' is NavSource's standing for the post-State-Department record - a secondary roster elsewhere carries 'scrapped 1947' (see gaps).

- US National Archives photo NWDNS-26-G-4098 shows 'Marines unload supplies from USS LSM-201 and USS LST-807, and other amphibious warships beached at Iwo Jima on D-Day' (caption dated 15 February 1945 in the NavSource transcription - see limitations). A second photograph, credited to William E. Jayne of USS LST-399, shows LST-807 on the beach at Iwo Jima on 23 February 1945 with Red Beach under Japanese mortar attack. A third photo (private, Followell) shows the ship underway on the Mississippi after leaving the Evansville builder's yard, September-October 1944 - the river-transit delivery route of the 'cornfield yards.'

- LST-807 crew and embarked/unloading Marines at Iwo Jima (Feb 1945)
- Limitations
- Archival lead only: photographs establish physical presence at the Iwo Jima beachhead, not work performed or materials aboard. NARA catalog is JS-rendered and could not be independently fetched; the NWDNS identifier and caption text are transcribed via NavSource. The '15 February 1945' caption date precedes the actual Iwo Jima D-Day landings of 19 February 1945 and the ship's documented participation window of 20-26 February - a caption-level inconsistency flagged in gaps, not corrected here.

- Finding
- The official BuShips design table for the LST542-931 group (which contains hull 807): 328 ft overall (316 ft pp), 50 ft beam, 2,366 t light / 4,080 t trial displacement, 11.6 kt trial speed, two GM 12-567A diesel engines rated 1,700 shp on two propellers, total accommodations 13 officers / 106 enlisted. The table confirms this is a diesel plant with no boilers or steam conditions listed (steam columns populated only for the turbine-driven LST1153+ series, a different later class).

- Finding type
- asbestos_application
- Finding
- A diesel-powered tank landing ship built July-October 1944 sits inside the Navy's documented asbestos-use era. Era-standard applications aboard an LST of this type and period were GM diesel-exhaust lagging, exhaust and machinery gaskets, engine-room thermal and acoustic insulation, deck coverings/tile, bulkhead and accommodation insulation, winch and windlass brake linings, and valve packing. Because the plant is diesel with no boilers or steam system, the boiler/turbine steam-lagging pathway of steam vessels does not apply.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, material schedule, abatement contract, hazmat disclosure, or verified litigation naming USS LST-807 was found in the public sources searched. CAVEAT: CourtListener could not be queried this session - the authenticated helper reported the fleet daily quota exhausted (server-requested wait 37,266 s, ~10.4 h) and was not retried, per batch rules; logged as blocked in search_ledger, not as a negative result. Secondary web sweeps surfaced no qualifying case naming this hull; the only 'asbestos aboard' material is law-firm marketing content (ship-list listicles, incl. a class-level 'LST 542' marketing page) asserting asbestos without primary sourcing - excluded by source policy.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - and the litigation repository search is a genuine open gap (throttled at daily quota, not run). Deck logs (RG 24), BuShips construction work packages, and any State Department/Foreign Liquidation Commission disposal file are undigitized leads. Does not establish or defeat any claim of exposure or legal eligibility.
