    Finding
    MARAD ShipHistory database record for LST-463 (Detail 5999) carries a digitized Maritime Commission vessel status card (image 5999_AF.jpg), which reads: header 'LST-463' stamped 'SOLD PDX-385'; LOCATION 'U. S. Naval Station, San Diego, Calif.'; 'Declared surplus 7-18-46'; DISPOSITION 'Sold to Dulien Steel Products, Inc. Sept. 23, 1947 for scrapping of hull under PDX-385 for $7,376'; REMARKS 'Offered for scrapping of hull under PDX-385 opening 9/8/47.' The card establishes the hull's fate expressly - sold for scrapping, at San Diego, under a documented disposal sale - superseding NavSource's 'fate unknown' and refining DANFS's bare 3 November 1947 sale date. The database header fields list Year Built 1943, 'Shipyard: American Bridge Company' (a data-field error conflicting with Kaiser Vancouver - see gaps), General Type 'Naval Combatant', Specific Type 'LST Tank Landing Ship', fate 'Sold - Scrap'.

    Limitations
    Primary disposal document (the MC/MARAD custody card) read directly from the scan. The card's sale date (23 September 1947) precedes the DANFS/NavSource sale date (3 November 1947) - likely award-vs-delivery distinction; both dates are reported, unresolved (see gaps). The card records the sale and scrapping purpose, not the breakup site or date. The page's 'American Bridge Company' shipyard field conflicts with Kaiser Vancouver (DANFS, NavSource, production table, BuShips roster all agree) - treated as a database-field error on the MARAD record, not as evidence of a second hull. Contains no asbestos, materials, or condition information; supports no asbestos claim.

Documented operations: loaded at Cape Cretin for the Hollandia assault (April 1944, under Capt. R. M. Scruggs; landings 22 April); Lingayen - 'LSTs 463, 466(FF), 475, and 482 loaded at Hollandia,' departed Humboldt Bay 27 December 1944, rendezvoused at Aitape 28 December; en route 6 January 1945 two torpedoes from a midget submarine passed close with no damage; air attacks 7-10 January, 'no damage to LSTs resulted'; during the 9 January unloading at White Beaches ONE and TWO, 'LSTs 463, 469, 470, and 475 all received hits from enemy mortar fire during unloading operations, but only slight damage resulted, and casualties were light.' On 24 January 1945 LSTs 463 and 473 departed Leyte for the Subic Bay initial landings 29 January, returning 3 February. On 14 April 1945 LSTs 168(GF), 170, 245, 458, 463, 470, 473, and 474(GF) departed Mindoro for the Illana Bay, Mindanao assault landings 17 April. On the June 1945 Okinawa resupply mission 'LST 463 was subjected to enemy air attacks but suffered no damage.' Homeward bound: 'departed from the Philippines on 7 December 1945 with LSTs 463, 466, and 474(GF), proceeded to Pearl Harbor, then to San Diego, California, and arrived at San Diego on 10 January 1946.'

    asbestos_application
    Finding
    Asbestos-relevant construction context for this hull's type: the LST-1 class is a diesel-propelled design (two GM 12-567A engines, no boilers - BuShips Ships' Data 1945 v2 design group LST1-490; NavSource specifications), so the boiler/main-steam-pipe lagging pathway of steam warships does not apply. Era-standard asbestos applications aboard a 1942 diesel amphibious ship of this type concentrate in engine and diesel-exhaust lagging, flange and machinery gaskets, valve packing, deck coverings (mastic/tile compounds), and insulation in accommodation spaces. WWII naval and Maritime Commission construction was a documented federal asbestos-use sector: asbestos was an extensively used insulating and fireproofing material in U.S. shipbuilding during WWII, when asbestos supply was reserved for shipbuilding (Corn & Starr 1987). Her documented battle damage and repair cycles (Lingayen mortar hits, January 1945 - flotilla history) are the class of events that disturbed interior materials on era hulls, though no repair record or work package for this hull was located.

No authoritative source located corroborates a kamikaze strike on this hull: the LST Flotilla SEVEN unit history records only enemy MORTAR hits at Lingayen Gulf on 9 January 1945 - 'LSTs 463, 469, 470, and 475 all received hits from enemy mortar fire during unloading operations, but only slight damage resulted, and casualties were light' - and records that during the June 1945 Okinawa resupply 'LST 463 was subjected to enemy air attacks but suffered no damage'; it also records 'no ship of Flotilla SEVEN was seriously damaged' during the Lingayen operation. The photographs document genuine damage/grounding but their kamikaze attribution is contributed-caption content, undated, and unsupported by the flotilla's own operational record.

    Finding
    Archival leads (not retrieved - require research-room or reproduction order; no spend authorized): (a) WWII deck logs for LST-463 (Feb 1943-Jun 1946) are within NARA RG 24 'Logbooks of U.S. Navy Ships and Stations, 1941-1978' (NAID 594258) at College Park - the authoritative daily record for underway, availability, and damage-repair periods (would settle the Lingayen damage and any repair availabilities); (b) two NARA-held photographs are identified via NavSource captions - NARA photo 80-G-57464 (LST-463 with LST-18 beached at Cape Gloucester, Dec 1943-Jan 1944) and US Naval Historical Center photo NH 91270 (LST-463 with LSM-63 at Lingayen Gulf, D-Day 9 January 1945); (c) no 'USS LST-463 - War History' item surfaced in the NARA catalog index this session (sister hull LST-464's war history is NAID 77707313 in RG 38 - a comparable item may exist for 463 but was not located); (d) NHHC Ships' History Branch holds the DANFS source file for LST-463.

    Limitations
    Record-group and item-level mapping only - no box-level or item-level retrieval performed. Deck logs and war diaries document operations and damage, not materials; whether any asbestos-relevant document exists in these files is unknown until surveyed. Nothing in this row is an asbestos finding.

    Finding
    No qualifying ship-specific asbestos record located: no asbestos survey, abatement record, material schedule, hazmat disclosure, or verified litigation naming USS LST-463 was found in the public sources searched - DANFS, NavSource, the BuShips roster, the MARAD status card, and the Flotilla SEVEN unit history contain no asbestos or insulation-material statement; the ship was stricken in 1946 and sold for scrapping in 1947, predating the Naval Vessel Register's post-1987-disposal inclusion window (NVR contains no detail page for this hull). All four planned CourtListener queries completed with zero results: opinion searches on 'LST-463', 'USS LST-463', and 'LST 463', and the docket search on 'LST-463' (three of the four completed on the relaunch session after the prior session's fleet-pacing stand-down). Secondary web sweeps surfaced no qualifying asbestos litigation naming the hull.

    Limitations
    Absence of a located public record does not prove absence of asbestos aboard - a 1942-built amphibious warship is era-consistent with asbestos-containing materials in the applications named in ev-08, and the hull saw documented battle damage and repair cycles. CourtListener coverage is complete: all four planned queries (opinion: 'LST-463', 'USS LST-463', 'LST 463'; docket: 'LST-463') returned count=0 - a true negative for indexed litigation naming the hull, not proof no case was ever filed. Does not establish or defeat any exposure claim or legal eligibility.
