Truman approved the idea of the H-Bomb. This bomb was a huge impact for the US.
This one bomb was smaller in size than the Hiroshima atomic bomb but 2500 times more powerful.
Designed in 1948, first flown in 1952, and first used by US military in 1955. This bomb could travel 6,000 miles. The making of the bomb was very expensive and American was financially helped by the Government. That was something American could do, but Soviet Union could not.
America built fewer but better quality missiles than the Soviet Union. The Atlas could go 5,000 miles at a speed of 16,000 mph. By 1961, there were enough bombs to destroy the world.
