Sedan was a thermonuclear device with a fission yield less than 30% and a fusion yield about 70%. [3] [4] According to Carey Sublette, the design of the Sedan device was similar to that used in the Bluestone and Swanee tests of Operation Dominic conducted days and months prior to Sedan respectively, and was therefore not unlike the W56 high yield Minuteman I missile warhead.

The 1962 "Sedan" plowshares shot displaced 12 million tons of earth and created a crater 320 feet (98 m) deep and 1,280 feet (390 m) wide.Project Plowshare was the overall United States program for the development of techniques to use nuclear explosives for peaceful construction purposes.
A Mark 6 nuclear bomb, similar to the one dropped in the incident, at the National Museum of the United States Air Force.. On March 11, 1958, a U.S. Air Force Boeing B-47E-LM Stratojet from Hunter Air Force Base operated by the 375th Bombardment Squadron of the 308th Bombardment Wing near Savannah, Georgia, took off at approximately 4:34 PM and was scheduled to fly to the United Kingdom and ...
Crater created by the Sedan shallow underground nuclear test explosion A flooded crater produced by the 2020 Beirut explosion.In a large explosion like this, the energy may not only cause destruction like that shown in the picture, but eject large amounts of material from the ground, creating a hole in the earth.
Described as a "near clone" of the Sedan shot, Chagan's yield was the equivalent of 140 kilotons of TNT and sought to produce a large conical crater suitable for a lake. The site was a dry bed of the Chagan River (tributary of Irtysh River) at the edge of the Semipalatinsk Test Site, and was chosen such that the lip of the crater would dam the ...
Operation Buster–Jangle was a series of seven (six atmospheric, one cratering) nuclear weapons tests conducted by the United States in late 1951 at the Nevada Test Site. Buster–Jangle was the first joint test program between the DOD (Operation Buster) and Los Alamos National Laboratories (Operation Jangle).
A frightening moment in the 1950s has mostly been forgotten today — the release of an unloaded nuclear bomb by the Air Force over the Palmetto State. ... The crater from the blast is still ...
A crater could develop when an underground nuclear explosion vaporized surrounding bedrock and sediment. The vapor cooled to liquid lava and pooled at the bottom of the cavity created by the explosion. Cracked rock and sediment layers above the explosion often settled into the cavity to form a crater.
