- Finding
- Primary government award file for this hull: the Navy Unit Commendation was awarded 'for extremely meritorious service in support of military operations as First-Aid Ship during the Campaign to recapture the Philippines from October 24 to December 30, 1944' - she received and cared for casualties under 'enemy Japanese gunfire and repeated dive-bombing and suicide-plane attacks,' proceeded 'boldly to beach or ship to take aboard men stricken in battle, often far in excess of her designed capacity,' and 'was recognized by the enemy as a potential factor toward the success of our forces and was singled out as a major target for Japanese airmen.' Enclosures document: Humboldt Bay-area operations through 6 July 1944; a restricted message citing 'excellent surgical care' given 'over fifteen hundred wounded of both Army Navy in the past month under hazardous conditions'; continuous Leyte Gulf presence 'since A day' with casualties taken from stricken ships and from shore; and Army commendation for operations 'from A-day to 5 January 1945' in the landing beaches' vicinity.

- Finding
- Official flotilla unit history naming this hull: LST-464 was among the ships originally assigned to LST Flotilla Seven (organized Panama City, Florida, February 1943); she departed San Francisco 24 April 1943 with Commander LST Flotilla Seven in LST-470 and LSTs 462, 464-469, 471, called at Tutuila, Samoa (14 May) and Wellington, New Zealand (29 May), and arrived Sydney, Australia 8 June 1943, reporting to Commander Seventh Amphibious Force. The history records that 'LST 464 was supplied with medical equipment and used as a first-aid ship. This ship was later equipped with extensive hospital facilities and used exclusively as a first-aid and casualty evacuation ship, with the designation of LST (H) 464' - and that such converted ships were removed from flotilla operations. The flotilla's manning table places LST-464 in a Navy-manned group.

Yard header: Kaiser's Vancouver operation was an emergency yard built with 10 ways in the fourth wave of shipbuilding expansion with $26 million in U.S. Maritime Commission funding; ways increased to 12 in the fifth wave; the yard was closed at the end of the war and held in reserve until the 1950s, when it was sold to Gilmore Steel.

- Finding type
- asbestos_application
- Finding
- Era/design inference for a diesel-powered amphibious ship built in 1942 at a Maritime Commission-funded emergency yard: NO boilers or steam plant - the steam-lagging pathway does not apply; plausible asbestos applications on this type concentrate in diesel-engine and exhaust-system insulation, gaskets and packing throughout the engineering spaces, electrical insulation/cable, deck coverings (including tank-deck surfaces), accommodation-space insulation, and brake/friction linings on winches and the stern-anchor windlass. Peer-reviewed scholarship (Corn & Starr 1987) documents that asbestos was used extensively as fireproofing and insulating material in WWII U.S. shipbuilding and that the federal government reserved asbestos supply for shipbuilding; GAO HRD-80-2 documents that the Navy did not begin systematic asbestos substitution until the early 1970s - roughly 25 years after this hull left Navy custody (1948). The 1943 Sydney first-aid-ship conversion added interior compartmental rework of undocumented material scope.

CourtListener authenticated sweeps - opinions for 'LST-464', 'LST 464', 'USS LST-464', 'LST(H)-464' and RECAP dockets for 'LST-464', 'LST 464' - returned zero hits of any kind. The Kaiser Asbestos Personal Injury Trust's published Approved Jobsite List was checked and does NOT include the Kaiser Vancouver yard (only Richmond Shipyards 1 & 2 appear among Kaiser facilities) - the trust is not evidence for this builder yard. The Naval Vessel Register does not cover vessels disposed of before 1987 - LST-464 has no NVR record.

- Absence of a located public record does not prove absence of asbestos aboard - a 1942 diesel-powered hull is consistent with retained era materials through its 1946 decommissioning, and both the 1943 conversion and 1948 disposal are undocumented material events. Does not establish that asbestos was or was not present; does not establish or defeat any claim of exposure or legal eligibility.
