Following Test Baker at Bikini Atoll, a program of target vessel decontamination was begun August 1, 1946. Here, a Navy fireboat washes down battleship New York to reduce radioactive contamination after the blast passed over it.
Operation Crossroads consisted of two 23 kiloton nuclear detonations. Test Able detonated at an altitude of 520 feet on July 1, 1946, and Test Baker was detonated 90 feet underwater on July 25, 1946.
A third planned detonation, Test Charlie, was canceled after the United States Navy was unable to decontaminate ships used in the Test Baker experiments.
