The visual effects of a high-altitude or space-based explosion may last longer than atmospheric tests, sometimes in excess of 30 minutes. Heat from the Bluegill Triple Prime shot, at an altitude of 50 kilometers (31 miles), was felt by personnel on the ground at Johnston Atoll , and this test caused retina burns to two personnel at ground zero ...
Overpressure in an enclosed space is determined using "Weibull's formula": [5] [6] = where: 22.5 is a constant based on experimentation = (kilograms) net explosive mass calculated using all explosive materials and their relative effectiveness
It was launched from Johnston Atoll on July 9, 1962, and was the largest nuclear test conducted in outer space, and one of five conducted by the US in space. A Thor rocket carrying a W49 thermonuclear warhead (designed at Los Alamos Scientific Laboratory ) and a Mk. 2 reentry vehicle was launched from Johnston Atoll in the Pacific Ocean, about ...

The single-most important thing to remember if a nuclear bomb is supposed to explode, he says, is to shelter in place. "There were survivors in Hiroshima within 300 meters of the epicenter ...
By the end of World War II in Europe in May 1945, more than 3,000 V-2s had been launched. [2] In addition to its use as a weapon, a vertically launched V-2 became the first human-made object to reach outer space on June 20, 1944. [3] The R-7 Semyorka was the first intercontinental ballistic missile. [4]
This is a compilation of published detonation velocities for various high explosive compounds. Detonation velocity is the speed with which the detonation shock wave travels through the explosive.
Developed between 1956 and 1961 as the Soviet Union engaged in a nuclear arms race with the United States, the Tsar Bomba - the King of Bombs - was the largest hydrogen bomb ever and was claimed ...
