'Struck 1956' gives no month/day; 'decommissioned, date unknown' is undated; 'fate unknown' leaves disposal undocumented. Contains no asbestos or material-content information.

- Finding
- NARA holds deck logs for this hull indexed as LCI(L)(FF)-504, coverage 11/23/1943 - 6/30/1945. The coverage window begins on the documented commissioning date (23 November 1943), independently corroborating that milestone. The indexed coverage ends 30 June 1945, well before the ship's documented end of active service (occupation duty into January 1946; lay-up March 1946) - the later logs are not in this index entry (see gaps).

- Finding
- This hull is named three times in the official Fifth Amphibious Force occupation report. (1) Task organization: under Task Group 54.2, '54.2.2 LST Flotilla 37 (Temp) - Captain Riley' carries 'Flotilla Flagship LC(FF) 504' - the ship served as flagship of a temporary LST flotilla for the occupation movement. (2) The daily summary for 0000-2400, 22 September 1945 - the day TG 54.1 arrived Sasebo at 0600 and the 5th Marine Division commenced landing at 0900 - lists 'LCIs 504 and 606' among the day's arrivals. (3) A communications assignment table lists 'LC(FF) 504 (ComLSTFlot 37)' among the flotilla flagships. This is primary documentation of the hull's occupation-duty role at Sasebo, Kyushu, in September-October 1945.

- Limitations
- Primary source for operational assignment and presence only - contains no asbestos or material-content information. The scan is hosted on Wikimedia Commons (a tertiary host); the document itself is the official report with serial and endorsement block intact. The 22 September arrivals list places the hull with the day's arrivals in the Sasebo operation; it does not detail her individual movements. OCR of the scanned table is imperfect ('CamLSTFlot' = ComLSTFlot, 'LCIts' = LCIs) - readings were verified against the layout text layer.

- The Navy Occupation Service Medal eligibility table lists 'LC (FF) 504' with two qualifying windows in occupation area 'A': 22-25 September 1945 and 19 October 1945 - 18 January 1946. The September window corroborates the Fifth Amphibious Force report's placement of the hull at the Sasebo landings (arrival logged 22 September 1945); the later window extends documented occupation service into January 1946, immediately before the documented March 1946 lay-up at Green Cove Springs.

[6]Era inference built on: NavSource LCI-351 class spec block (diesel propulsion, 1943 steel-hulled construction at New Jersey Shipbuilding Corp.); GAO HRD-80-2 Navy asbestos-era documentation (see ev-06) [other_primary]

- Finding type
- asbestos_application
- Finding
- A steel-hulled diesel-powered landing craft built in late 1943 at New Jersey Shipbuilding Corp., Barber, NJ sits inside the Navy's documented asbestos-use era; era-standard applications aboard a small combatant of this type and period were engine-exhaust and muffler lagging, machinery thermal insulation, gaskets, valve packing, and electrical insulation in the confined hull volume. As a diesel-powered craft she carried no steam plant - the boiler/turbine lagging pathway of steam vessels does not apply, and her '2-inch plastic splinter protection' armor is not an asbestos product. The LC(FF) conversion added command and communications spaces for embarked flotilla staff - more insulated and wired volume, same era materials environment.

No quantity. The builder yard (New Jersey Shipbuilding, Barber NJ) has no located asbestos-specific documentation of its own - inference rests on era and Navy practice, not yard records.

- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or qualifying litigation naming USS LCI(L)-504 / LC(FF)-504 was found in the public sources searched (see search_ledger). CourtListener exact-phrase searches at opinion level returned zero for all designation variants ('LC(FF)-504', 'LCI-504', 'LCI(L)-504'); at docket level 'LCI(L)-504' returned zero and 'LCI-504' returned only fuzzy collisions (e.g., an 'LCI' investigator credential adjacent to a '(504)' New Orleans area-code phone number in an E.D. La. tort docket - not ship-related). Secondary web sweep surfaced no asbestos claim of any kind for this hull - not even law-firm marketing listicles.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - the hull was built inside the Navy's asbestos era and its final disposition after the 1956 striking is unknown, leaving no post-service material record and no surviving hull to survey. CourtListener coverage is limited by designation-string searching: it cannot reach PACER filings or state-court complaints that never name the hull verbatim, and two docket-level queries could not be completed before session end due to shared fleet pacing (see search_ledger). Deck logs (NARA College Park, coverage 1943-45 only) and any BuShips construction/work-package records are undigitized leads. Does not establish or defeat any claim of exposure or legal eligibility.
