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 Mark 4 nuclear bomb was an American implosion-type nuclear bomb based on the earlier Mark 3 Fat Man design, used in the Trinity test and the bombing of Nagasaki.With the Mark 3 needing each individual component to be hand-assembled by only highly trained technicians under closely controlled conditions, the purpose of the Mark 4 was to produce an atomic weapon as a practical piece of ordnance.
The operation consisted of 29 explosions, of which only two did not produce any nuclear yield.Twenty-one laboratories and government agencies were involved. While most Operation Plumbbob tests contributed to the development of warheads for intercontinental and intermediate range missiles, they also tested air defense and anti-submarine warheads with smaller yields.
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 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. There are three existing basic design ...
Nuclear bomb damaged in crash [34] During a simulated takeoff, a wheel casting failure caused the tail of a USAF B-47 carrying a Mark 36 Mod 1 nuclear bomb to hit the runway, rupturing a fuel tank and sparking a fire which burned for some 7 hours. [35] The weapon used in-flight insertion and the weapon was in its retracted, unarmed state. [36]
A side-effect of the Pascal-B nuclear test during Operation Plumbbob may have resulted in the first man-made object launched into space. The so-called "thunder well" effect from the underground explosion may have launched a metal cover plate into space at six times Earth's escape velocity, although the evidence remains subject to debate.
MC3810 Mk5 Arming, Fuzing and Firing system used on the W88. The W88 is an American thermonuclear warhead, with an estimated yield of 475 kilotons of TNT (1,990 TJ), [2] and is small enough to fit on MIRVed missiles. The W88 was designed at the Los Alamos National Laboratory in the 1970s.
