Truman announces development of H-bomb

January 31, 1950, President Harry S. Truman announced his decision to support the development of the hydrogen bomb five months after the Soviet Union detonated its own atomic bomb and after British and U.S. intelligence’s conclusion that a top scientist in the U.S. nuclear program was a spy for the Soviet Union. Exacerbating the American-Soviet arms race, Truman approved massive funding to develop the first H-bomb. On November 1, 1952, the United States detonated the world’s first hydrogen bomb on the Elugelab Atoll in the Pacific Marshall Islands.
