The atomic bomb ended the war against Japan in 1945 and became the centerpiece of U.S. and Soviet military strategy for the next 45 years. In the late 1940s the debate over whether the atomic bomb was the ultimate arbitrator of international differences led to the infamous carrier versus B 36 controversy in American defense policy; American school children in the 1950s practiced air raid drills as many feared an atomic attack against American cities; and billions were spent to develop and procure vast fleets of B 36, B 47, and B 52 nuclear bombers, that led to a still alive legacy that is seen in the current B 1 and the B 2 stealth bomber controversies. In this comprehensive work, two leading weapons experts present a complete and fully up to date history of the development of U.S. nuclear weapons and detailed descriptions of the entire American nuclear arsenal, including the variety of systems capable of delivering them. Illustrated with more than 100 b/w photographs and 20 charts, the authors describe all of the nuclear weapons used in formulating American defense policies, including the U.S. Army's development of the 280 mm atomic cannon, atomic demolitions, and the atomic grenade launcher, along with the U.S. Navy's development of a carrier based nuclear strike capability. Details are provided about the Navy's ASTOR nuclear torpedo, the 16 inch nuclear projectiles for the Iowa class battleships, and even the Navy s drone helicopter designed to carry a nuclear depth charge. In addition, they discuss the nuclear missiles and rockets carried by the air defense fighters within the United States and the nuclear armed surface to air missiles ringing major U.S. cities and military bases. This new work is certain to be considered the definitive study of the subject.
