    Finding
    DANFS documents the hull's full Navy arc: laid down 2 January 1945 at Charleston, S.C., by the Charleston Navy Yard; launched 22 January 1945; sponsored by Mrs. Percy H. Wood; commissioned 7 April 1945. Shakedown in Chesapeake Bay, then training out of San Diego; departed for the Pacific war in mid-August 1945 and received word of Japan's capitulation en route to Hawaii; entered Pearl Harbor 21 August 1945; returned to San Diego 9 October 1945 and trained on the Pacific coast for five years. Korean War: departed San Diego 10 July 1950, reached Yokosuka 6 August; as TF 90 element in Operation Chromite, at 0615 on 15 September 1950 LSMR-401 with sisters LSMR-403 and LSMR-404 (each carrying a 1,000-round allowance of 5-inch spin-stabilized rockets) delivered the pre-assault rocket bombardment of Wolmi Do, then shelled the Inchon tidal basin, Blue Beach, and the right flank before the main landing. Returned to Japan 20 September; covered the Hungnam evacuation (first rocket barrage 21 December 1950, withdrawal covered through 24 December); supported the January 1951 Inchon evacuation stage via Taechon; and across the 1951-52 static-war phase conducted roughly eight months of harbor-siege fire support at Wonsan and Songjin on the east coast and Chinnampo, Inchon, and Taeju on the west coast. Third Far East deployment arrived Yokosuka 29 July 1953, two days after the armistice; armistice-enforcement patrols and port calls followed. Final departure Yokosuka 10 March 1954, San Diego arrival 6 April 1954, Puget Sound June 1954, placed in commission in reserve at Astoria, Oregon, 6 July 1954 for inactivation overhaul, out of commission later in 1954, berthed Columbia River Group Pacific Reserve Fleet; named Big Black River 1 October 1955; redesignated inshore fire support ship LFR-401 on 1 January 1969; stricken 1 May 1973. Earned seven battle stars for the Korean conflict as LSMR-401.

    Finding
    Government of Canada records this hull's end-of-life environmental action: on 6 January 2020 the Minister of Fisheries, Oceans and the Canadian Coast Guard announced removal of the derelict MV Spudnik (the ex-LSM(R)-401 hull) from the Fraser River near Surrey, B.C.; the 2019 vessel assessment found 'imminent risks of pollution threat, hull corrosion, possible sinking and fire'; bulk pollutants had been removed in 2014 after the vessel broke its moorings in Howe Sound and was towed to New Westminster by a Coast Guard tug carrying roughly 5,000 litres of diesel and 1,500 litres of lubricating oil; the Canadian Coast Guard retained contractor Marine Recycling Corporation to dismantle and remove the vessel, with removal completed in 2020 (diamond-wire saw-cutting into sections by subcontractor West Coast Cutting & Coring, sections lifted by the 600-ton barge crane Arctic Tuk; estimated cost ~$3.3M CAD per CBC/CP).

    Documents an end-of-life pollution/corrosion hazard and funded dismantling of this specific hull - NOT an asbestos record: the release's 'pollution' refers to petroleum products and hull integrity; no asbestos survey or abatement statement appears in the release or cited coverage. Dismantling trades encountered whatever era materials remained aboard; that material content is undocumented here.

    DANFS final-paragraph inactivation chronology; NavSource timeline bullet 'Decommissioned, 15 February 1954'

    historical_record
    Finding
    Source discrepancy resolved: NavSource's timeline states 'Decommissioned, 15 February 1954' and 'Laid up in the Pacific Reserve Fleet in February 1954,' but DANFS documents the ship still on active Far East duty through that date - final departure from Yokosuka 10 March 1954, San Diego arrival 6 April 1954, move north to Puget Sound June 1954, placement in commission in reserve at Astoria 6 July 1954, and out of commission 'later that same year.' A 15 February 1954 decommissioning is incompatible with the documented March-April 1954 trans-Pacific transit; DANFS is controlling and the inactivation sequence (July 1954 in-reserve, later-1954 out-of-commission, Astoria Columbia River Group) is adopted.

    asbestos_application
    Finding
    Era inference for this hull: a 1945-built naval amphibious vessel constructed at Charleston Navy Yard during the wartime peak of asbestos use in U.S. shipbuilding - the period when the federal government had reserved asbestos supply for the shipbuilding program. Propulsion was diesel (two GM 16-278A engines; no boilers or steam plant), so the boiler-lagging pathway of steam vessels does not apply; the era-standard applications aboard a vessel of this type and period were thermal insulation, machinery and diesel-exhaust lagging, gaskets, valve packing, electrical insulation, and interior fireproofing/deck material.

    No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or docketed case naming USS LSM(R)-401 / LSMR-401 / LFR-401 / Big Black River / Arctic Transport / Spudnik was found in the public sources searched. CourtListener: the opinion search for "LSMR-401" returned zero hits; further CourtListener queries this session were rate-limited by the shared fleet pace (logged as blocked, not a negative result). Secondary web sweeps surfaced no qualifying case; the DFO/Canadian-Coast-Guard derelict record (ev-03) documents a petroleum/corrosion hazard, not asbestos. The only 'asbestos aboard' content anywhere is law-firm marketing material asserting asbestos on WWII-era hulls generally without primary sourcing - excluded by source policy.

    Absence of a located public record does not prove absence of asbestos aboard - a 1945 naval hull's era materials are consistent with retained ACM, and the 2020 dismantling documentation is silent on fiber. Litigation coverage is incomplete (CourtListener mostly pace-limited). Does not establish or defeat any claim of exposure or legal eligibility.
