   Finding

   Destroyer History Foundation ship profile for USS Morrison (DD-560): Morrison 'was the builder's seventh of 21 2100-ton Fletcher-class destroyers' built by Seattle-Tacoma Shipbuilding Corp.; commissioned 'the 137th of 175 2,100-tonners to join the fleet'; described as 'the lone US Navy destroyer awarded two Navy Unit Commendations for action in World War II.' Under repair at Hunters Point 17 November 1944 - 9 February 1945; training off Hawaii 15 February - 3 March. Radar-picket sequence: stations #10 west, #7 south, #2 northeast relieving Daly on the 28th, then adjacent #1 on 30 April. Loss account: on station with Ingraham (DD-694) and four landing craft; four suiciders struck Morrison in quick succession, three more grazed, two narrowly missed; 'sank in fifteen minutes'; 'pall bearer' LCS-21 'picked up 179 officers and men, 108 of whom were injured'; 152 lost - 'all the more regretted in view of the gallant fight to the finish' (Capt. Frederick Moosbrugger, commanding the Okinawa destroyers). 31 March submarine identified as I-8. In July 1957 remains donated to the government of the Ryukyu Islands for salvage.

   Source discrepancies resolved or logged: (a) Sinking date - DANFS (1963 text), the current NHHC entry, the second NUC citation ('May 4, 1945'), NavSource, and the U.S. Navy Memorial all read 4 May 1945; navypedia's class table reads 'sunk 3.5.1945' (a one-day-early date, plausibly a UTC conversion of the 0840 local sinking) - 4 May 1945 controls. (b) The 1963-edition DANFS transcription carries century typos in the namesake biography ('1955', '15 February 1962', '15 July 1962', '31 March 1963'); the current NHHC entry has the correct 1855/1862/1863 dates - logged as transcription errors. (c) Task group designation - 1963 DANFS reads 'TG 83.3' for the October 1944 picket assignment; the current NHHC entry reads 'TG 38.3' - TG 38.3 is consistent with the Third Fleet fast-carrier organization and controls. (d) Departure from the west coast after the Hunters Point repair - 1963 DANFS reads 'On 9 February the destroyer steamed back'; the current NHHC entry and Tin Can Sailors read 10 February 1945 - logged unresolved (both are consistent with repair end 9 February / cast off 10 February). (e) NHHC photo caption reads 'christens the destroyer... on Independence Day 1944' while the launch was 4 July 1943 - caption-year error, logged. (f) Survivor/casualty figures - 152 lost is consistent across DANFS, NHHC, NavSource, and the Navy Memorial; destroyerhistory gives LCS-21's pickup as 179 (108 injured); kamikazeimages.net's reunion account gives 187 survivors/155 lost; hmscavalier.org.uk book excerpt gives 155 killed/172 survivors - the official 152 is carried; survivor-count variance logged. (g) Torpedo-tube count - the 1963 DANFS spec block reads '8 21" tt.'; the SDB 1945 per-hull row reads 2 x 21" quintuple mounts (i.e., ten tubes), NavSource reads 10 x 21" tt (2x5), and Fletcher-class data uniformly carry two quintuple mounts - the contemporaneous official source controls and '8' is treated as a DANFS text error. (h) Speed figures - DANFS 35 kt, SDB 1945 trial 35.2 kt, NavSource 38 kt - logged.

The sunken hull was donated with ~26 other Ryukyus-area hulls to the Government of the Ryukyu Islands for salvage in July 1957 - a disposal transaction predating every modern regime governing hazardous materials in end-of-life vessels (Basel Convention in force 1992; EU Ship Recycling Regulation 2013; IMO Hong Kong Convention in force 2025).

    Finding

    No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, court finding, or docketed asbestos case naming USS Morrison, DD-560, or the hull's 1957 salvage transfer was found in the public sources searched (see search_ledger and the litigation_sweep row ev-uss-morrison-dd560-12 for the CourtListener detail). 'Morrison' is a high-collision surname (plaintiffs, Morrison-Knudsen corporate litigation, non-vessel references); any hit would require explicit vessel/hull-number linkage to qualify.

    Limitations

    Absence of a located public record does not prove absence of asbestos aboard - a 1940-contract Fletcher-class destroyer built 1942-43 with a documented four-boiler high-pressure steam plant is era-consistent with asbestos-containing materials; the hull's sinking on 4 May 1945 ended its material lifecycle a decade before Navy substitution policy changed, and any postwar salvage under the 1957 Ryukyu donation is undocumented. Does not establish presence or absence; does not establish or defeat any exposure claim or legal eligibility.

    Finding

    CourtListener authenticated API v4 sweep, 2026-09-27 (all calls via the fleet-paced helper cl-auth-search.py): (a) exact-name opinion search 'USS Morrison'/'U.S.S. Morrison' - count 0; (b) exact-name docket search - count 0, document_count 0; (c) hull-number opinion search '"DD-560"' - count 0; (d) hull-number docket search '"DD-560"' - count 7, all screened: Parklyn Bay Co. v. Liberty Ins. Corp. (N.D. Cal. 2013, insurance contract), JORDAN v. CIA (M.D. Ga. 2018, employment), Sluyter v. Wal-Mart (E.D. Mich. 2016), Schluter v. Encore Rehabilitation (E.D. Mich. 2019), James v. State of Florida (M.D. Fla. 2022, habeas), Finley v. Graham (S.D.N.Y. 2012, habeas), Schoolcraft v. City of New York (S.D.N.Y. 2010, civil rights) - every hit is a numeric token collision (form/exhibit/Bates-style numbering); none references a vessel, the Navy, asbestos, or a maritime party - all classified 'other litigation / name collision', none qualifying; (e) '"USS Morrison" asbestos' opinion search - count 0. No qualifying asbestos litigation names this hull. Supplementary phrasing queries ('aboard the Morrison', DD-560 + asbestos variants) were paced out by the shared fleet limiter at session close - recorded in sl-uss-morrison-dd560-09.

    Limitations

    Sweep covers CourtListener's corpus only (RECAP dockets + opinion clusters) - PACER-only dockets and state-court filings not in RECAP are outside its coverage, and the supplementary phrasing queries remained unserved at session close due to fleet pacing. 'Morrison' is a high-collision surname; zero qualifying hits means no *located* docketed asbestos case names the vessel - it does not prove no claim was ever filed, does not establish or defeat any exposure claim, and makes no merits statement about any litigation.
