The detonation was successful and had the full design yield of the W47Y1 at approximately 600 kilotons. The shot was designed to improve confidence in the US ballistic missile systems, though even after the test there was considerable controversy.
The experiment, part of the Operation Grommet nuclear test series, tested the unique W71 warhead design for the LIM-49 Spartan anti-ballistic missile. [2] [3] With an explosive yield of almost 5 megatons of TNT (21 PJ), the test was the largest underground explosion ever detonated by the United States. [4]
Some sources suggest the W55 evolved from the experimental bomb tested in the Hardtack I Olive nuclear test on July 22, 1958, which had a full two-stage yield estimated at 202 kilotons. [ citation needed ] Researcher Chuck Hansen claims based on his US nuclear program research that the W55 and W58 warheads shared a common primary or fission ...
A blast wave reflecting from a surface and forming a mach stem. The air burst is usually 100 to 1,000 m (330 to 3,280 ft) above the hypocenter to allow the shockwave of the fission or fusion driven explosion to bounce off the ground and back into itself, combining two wave fronts and creating a shockwave that is more forceful than the one resulting from a detonation at ground level.
W78 warheads are contained inside the MK12-A reentry vehicles of the LGM-30G Minuteman III. Drawing of the Mark 12A re-entry vehicle that houses the W78 warhead. The W78 is an American thermonuclear warhead with an estimated yield of 335–350 kilotonnes of TNT (1,400–1,460 TJ), deployed on the LGM-30G Minuteman III intercontinental ballistic missile (ICBM) and housed in the Mark 12A reentry ...
The rocket hit speeds of nearly 8,500 miles per hour after it was launched from the 4th Missile Test Range in Russia’s Astrakhan region last month, decimating a military site in Dnipro.
When Hawaii's ballistic missile threat system blared across the state on January 13, many people didn't know where to go, what to do, or if they could even survive a nuclear attack.
Operation Prairie Flat was a test involving the detonation of a 500-short-ton (450 t) spherical surface charge of TNT to evaluate airblast, ground shock and thermal effects of nuclear weapons. [ 1 ] Since TNT charges produce roughly double the airburst effect of nuclear weapons, it allowed testing the equivalent of a 1 kiloton of TNT (4.2 TJ ...
