Blast doors in a missile control bunker at Minot Air Force Base, North Dakota. The 25-ton blast door in the Cheyenne Mountain nuclear bunker is the main entrance to another blast door (background) beyond which the side tunnel branches into access tunnels to the main chambers.
The first nuclear explosive devices provided the basic building blocks of future weapons. Pictured is the Gadget device being prepared for the Trinity nuclear test.. Nuclear Weapons Design are physical, chemical, and engineering arrangements that cause the physics package [1] of a nuclear weapon to detonate.
For two thermonuclear bombs for which the general size and primary characteristics are well understood, the Ivy Mike test bomb and the modern W-80 cruise missile warhead variant of the W-61 design, the radiation pressure was calculated to be 73 × 10 ^ 6 bar (7.3 TPa) for the Ivy Mike design and 1,400 × 10 ^ 6 bar (140 TPa) for the W-80.
The bomb shelter was built in 1967 in response to the Cuban Missile Crisis that unfolded five years prior, widely considered by historians to be the closest humanity has come to full-scale nuclear ...
North Korea's first three nuclear tests (2006, 2009 and 2013) had a relatively low yield and do not appear to have been of a thermonuclear weapon design. In 2013, the South Korean Defense Ministry had speculated that North Korea might be trying to develop a "hydrogen bomb" and such a device might be North Korea's next weapons test.
The Mark 39 design was a thermonuclear bomb and had a yield of 3.8 megatons. [1] It weighed 6,500–6,750 pounds (2,950–3,060 kilograms), [2] and was about 11 feet, 8 inches long (3.556 meters) [2] with a diameter of 35 inches (89 cm). [2] The design is an improved Mark 15 nuclear bomb design (the TX-15-X3 design and Mark 39 Mod 0 were the ...
The first thing you'd see if a nuclear bomb exploded nearby is a flood of light so bright, you may think the sun blew up -- but don't try to drive away. If a nuclear bomb explodes nearby, here's ...
The George explosion conducted on May 8, 1951, was the world's first thermonuclear burn, though it was just a test design, unsuitable for weaponization. Shaped like a torus , the George device had a small amount of heavy isotopes of liquid hydrogen ( deuterium and tritium ) placed at its center.
