- Finding
- On 5 April 1945 (Thursday), off Okinawa, LST-810 was damaged in a collision with tank landing ship LST-273 at 26 deg 25 min N, 127 deg 42 min E - one of several same-day collision casualties in the Okinawa area recorded by the official chronology during the assault-and-occupation period in which DANFS places this hull.

- Limitations
- Damage event only: the chronology records the collision and position but not extent of damage, casualties, or repair history. Transcription of the official Navy chronology (HyperWar), not the printed volume; the entry names both hulls. No asbestos content - included because battle/collision damage and subsequent repair are the kind of material-disturbance events a hull record should note, not as an exposure finding.

- Finding
- An NHHC photograph (NH 79563, via the Vallejo Naval and Historical Museum) shows LST-810 with LCT(6)-803 loaded as deck cargo, underway in San Francisco Bay circa 1946 - physical-presence documentation of the hull's postwar return configuration. A privately contributed voyage-record image covers 6 October 1944 to 29 November 1945 (commissioning-through-occupation window). Deck logs for this hull (October 1944-July 1946) should exist in NARA RG 24 but are not publicly digitized - open archival lead for any future work-disturbance or repair inquiry (including the aftermath of the 5 April 1945 collision).

[6]Era inference built on: NavSource LST-542-class specification block (2 x GM 12-567A 900 hp diesels, Falk reduction gears, 1,700 shp - diesel plant, no boilers); GAO HRD-80-2 (see ev-06); Corn & Starr 1987 (see ev-07); DANFS construction record (1944 build at an inland emergency yard) [other_primary]

- Finding type
- asbestos_application
- Finding
- A tank landing ship mass-built in 1944 sits squarely inside the documented WWII-era Navy asbestos-use window. The LST-542 design is diesel-powered with no boilers or steam distribution system - the boiler/turbine steam-lagging pathway of steam vessels does not apply. Era-standard asbestos applications aboard a 1944 amphibious hull of this type were instead: engine-room and diesel-exhaust lagging, gaskets and valve packing on machinery and piping, deck coverings, accommodation-space insulation, and electrical insulation - all in the cramped, poorly ventilated interior volumes typical of the type.

Names era-standard applications, not confirmed installed materials; no quantity; no manufacturer attribution for this hull. Does not establish that asbestos is or was present aboard this specific vessel.

- Finding
- GAO documented that the Navy used asbestos insulation extensively aboard ships and did not begin substituting alternative insulation materials until the early 1970s - spanning this hull's entire construction (1944) and service era (1944-46).

- Finding
- Peer-reviewed historical study documenting that asbestos was used extensively as a fireproofing and insulating material in U.S. shipbuilding during WWII - the era and program under which this 1944 LST-542-class hull was mass-produced - and that wartime demand drove unprecedented asbestos utilization in ship construction.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or verified litigation naming USS LST-810 was found in the public sources searched (see search_ledger). CAVEAT: CourtListener could not be queried this session - the authenticated API returned HTTP 429 (shared fleet daily quota exhausted, ~7 h to reset at attempt time); logged as blocked in search_ledger, not as a negative result. Secondary web sweeps surfaced no qualifying case; the only 'asbestos aboard' material is law-firm marketing content asserting asbestos on Navy ships generally 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, not run). Deck logs, builder work packages, and any scrapping-contract records are undigitized leads. Does not establish or defeat any claim of exposure or legal eligibility.
