Only two minutes after the detonation, the cloud reached a height of 12.2 kilometers, or 40,000 feet. In its first fraction of a second, the blast created a fireball one-quarter the size of Manhattan. They demonstrate the immense power of this blast, equal to 10.4 million tons of TNT. This series of photographs was made at an altitude of 3,600 meters, or approximately 12,000 feet, at a distance of 80 kilometers, or 50 miles, from the detonation site. The thermonuclear device tested in Operation Mike weighed some 82 tons and took up the space of a small building to hold the cryogenic equipment that kept its deuterium hydrogen fuel in liquid form. ![]() The fusion releases even more energy, creating a blast many times more powerful than a basic fission weapon would. Thermonuclear weapons, or hydrogen bombs, use the energy of a primary fission explosion to ignite a hydrogen fusion reaction. NARRATOR: The world’s first thermonuclear weapon test, code-named Mike, was carried out by the United States at Enewetak atoll in the Marshall Islands, November 1, 1952.
