    During World War II, USS LSM-60 was assigned to the Asiatic-Pacific Theater with LSM Flotilla Five, LSM Group Fourteen, and LSM Division Twenty-Seven, participated in the assault and occupation of Iwo Jima from 19 February to 16 March 1945, and earned one battle star for World War II service.

    Finding
    The Defense Nuclear Agency's official Operation CROSSROADS-1946 report (DNA 6032F, 1984) records that the BAKER weapon was prepared on Kwajalein and on LSM-60 in Bikini Lagoon, encased in a watertight steel caisson, and suspended 90 feet (27 meters) below the ship, which had been extensively modified with rigging facilities, a laboratory, and special radio receivers and transmitters; that TG 1.1 laboratory personnel were evacuated from LSM-60 at 0545 on 25 July 1946; that BAKER detonated on schedule at 0835 on 25 July 1946; and that when the air cleared, Arkansas, LSM-60, and four LCTs were not in sight. Table 11 lists LSM-60 among ships sunk at BAKER, footnoted as the surface zero ship.

    Establishes the surface-zero role, bomb suspension geometry, unmanned status at detonation (the target fleet was unmanned for both tests), timing, and destruction. It does not document asbestos content, exposure, or causation, and records only a 1947 resurvey objective to attempt to locate a photographed hull section — not a confirmed wreck recovery.

    No ship-specific asbestos survey, product inventory, abatement record, or condition report was located. Because LSM-60 was a World War II U.S. Navy diesel landing ship, machinery or diesel-exhaust insulation, gaskets, packing, electrical insulation, and deck covering are possible class/era application categories, but none is documented aboard this hull.
