An early stage in the "Trinity" fireball, the first man-made nuclear explosion, 1945. The United States developed the first nuclear weapons during World War II in cooperation with the United Kingdom and Canada as part of the Manhattan Project, out of the apprehension that Nazi Germany would develop them first.
Intense thermal radiation at the hypocenter forms a nuclear fireball which, if the explosion is low enough in altitude, is often associated with a mushroom cloud. In a high-altitude burst where the density of the atmosphere is low, more energy is released as ionizing gamma radiation and X-rays than as an atmosphere-displacing shockwave.
It was the first project assigned to the United States Army Weapon Command in Rock Island, Illinois. [3] It remains one of the smallest nuclear weapon systems ever built, incorporating a warhead with yields of 10 to 20 tons of TNT (42 to 84 GJ). It is named after American folk hero, soldier, and congressman Davy Crockett.
The Tsar Bomba (Russian: Царь-бомба, romanized: Tsar'-bomba, IPA: [t͡sarʲ ˈbombə], lit. ' Tsar bomb '; code name: Ivan [5] or Vanya), also known by the alphanumerical designation "AN602", was a thermonuclear aerial bomb, and the most powerful nuclear weapon ever created and tested.
The fireball created by the explosion had a maximum radius of 2.9 to 3.3 km (1.8 to 2.1 mi). [20] [21] [22] The maximum radius was reached several seconds after the detonation, during which the hot fireball lifted up due to buoyancy. While still relatively close to the ground, the fireball had yet to reach its maximum dimensions and was thus ...
The Ryan FR Fireball is an American mixed-power (piston and jet-powered) fighter aircraft designed by Ryan Aeronautical for the United States Navy during World War II. It was the Navy's first aircraft with a jet engine . [ 1 ]
The exercise was conducted on September 14, 1954, under command of Marshal Georgy Zhukov to the north of Totskoye village in Orenburg Oblast, Russia. A revolution in nuclear strategic thought occurred with the introduction of the intercontinental ballistic missile (ICBM), which the Soviet Union first successfully tested in August 1957.
United States Department of Defense directive 5230.16, Nuclear Accident and Incident Public Affairs (PA) Guidance, [1] Chairman Joint Chiefs of Staff Manual 3150.03B Joint Reporting Structure Event and Incident Reporting, and the United States Air Force Operation Reporting System, as set out in Air Force Instruction 10-206 [2] detail a number of terms for reporting nuclear incidents internally ...
