Text from item: FB-16. The gigantic fireball from "Mike" - the largest ever produced - measured 3-1/4 miles in diameter. Operation IVY was conducted by Joint Task Force 132, for the Atomic Energy Commission and the Department of Defense, at the AEC's Pacific Proving Grounds in the Marshall Islands in the fall of 1952. Operation IVY involved an experimental thermonuclear or "hydrogen" detonation. The thermonuclear device, code-named MIKE, caused the greatest destructive effects ever noted from a single explosive device. The particular test island (ELUGELAB) of the atoll completely disappeared. The resulting nuclear "fireball" was the largest ever produced. Joint Task Force 132 was commanded by Major General Percy W. Clarkson, USA. Dr. Alvin Graves, of AEC's Los Alamos Scientific Laboratory, was Scientific Deputy to the Task Force Commander. Scientific and military tests were conducted by a Scientific Task Group, supported by Army, Navy and Air Force Task Groups. Photos #1 through #18 in this series were prepared by the Atomic Energy Commission and the Department of Defense. They are issued by the Federal Civil Defense Administration because as President Eisenhower has said, "If the peoples of the world are to conduct an intelligent search for peace, they must be armed with the significant facts of today's existence."
