- Notes: Participated in the assault landings at Iwo Jima and received one battle star for her WW2 service. Postwar, she was specially modified to be the float from which an A-bomb was suspended during test BAKER of Operation Crossroads at Bikini Atoll. Modifications included a well through the cargo deck, a derrick to lower the Mk.3A "Fat Man" type atomic bomb (encased in a watertight housing) 90 feet below the surface (halfway to the bottom at 180 feet), and a special antenna to receive the detonation signal. She was anchored at the center of a fleet of 95 assorted target vessels. At 0835 local time, 25 July 1946, the bomb was detonated, obliterating LSM-60 and sinking eight target ships including USS Arkansas, USS Saratoga,
and Prinz Eugen.
