TRUMAN ORDERS DEVELOPMENT OF THE HYDROGEN BOMB

Truman orders development of the hydrogen bomb

On January 31st, 1950, President Harry Truman announced that the United States would move ahead with development of a thermonuclear or hydrogen bomb. The decision followed the Soviet Union’s first atomic test and intense debate among scientists, soldiers, and policymakers about the future of nuclear weapons. A hydrogen bomb promised yields far beyond earlier fission devices, raising questions about strategy, morality, and the very possibility of controlled war. For the American military, Truman’s directive meant planning for a world in which strategic air forces and, later, missile forces would wield weapons of almost unimaginable destructive power. It accelerated the growth of Strategic Air Command and drove investments in warning systems, hardened bases, and eventually ballistic missile submarines. The order did not end arguments inside the services or the public square, but it set the course for an arms race that defined Cold War deterrence and the planning assumptions of generations of officers.
