Nuclear Weapon
A NUCLEAR WEAPON is an explosive device that derives its destructive force from nuclear reactions , either fission (fission bomb ) or from a combination of fission and fusion reactions (thermonuclear bomb ). Both bomb types release large quantities of energy from relatively small amounts of matter. The first test of a fission ("atomic") bomb released an amount of energy approximately equal to 20,000 tons of TNT (84 TJ ). The first thermonuclear ("hydrogen") bomb test released energy approximately equal to 10 million tons of TNT (42 PJ). A thermonuclear weapon weighing little more than 2,400 pounds (1,100 kg) can release energy equal to more than 1.2 million tons of TNT (5.0 PJ). A nuclear device no larger than traditional bombs can devastate an entire city by blast, fire, and radiation . Since they are weapons of mass destruction , the proliferation of nuclear weapons is a focus of international relations policy

Fat Man
"FAT MAN" was the codename for the atomic bomb that was detonated over the Japanese city of Nagasaki

by the United States on 9 August 1945. It was the second of the only two nuclear weapons ever used in warfare , the first being Little Boy , and its detonation marked the third-ever man-made nuclear explosion in history. It was built by scientists and engineers at Los Alamos Laboratory using plutonium from the Hanford Site and dropped from the Boeing B-29 Superfortress Bockscar . For the Fat Man

Mark 4 Nuclear Bomb
The MARK 4 nuclear bomb was an American nuclear bomb design produced starting in 1949 and in use until 1953. The Mark 4 was based on the earlier Mark 3 Fat Man
Fat Man
design, used in the Trinity test and the bombing of Nagasaki . The Mark 3 was essentially handmade and constituted an emergency wartime expedient design; the Mark 4 utilized essentially the same basic principles (materials, dimensions of the nuclear core and explosive components) but reengineered the overarching system to be safer and easier to produce. The basic idea was to "GI-proof" otherwise sensitive nuclear weapons. The Mark 4 was 60 inches (1.5 m) in diameter and 128 inches (3.3 m) long, the same basic dimensions as Mark 3. It weighed slightly more at 10,800 to 10,900 pounds (4,900 to 4,940 kg), depending on the specific Mark 4 version

W56
The W56 is an American thermonuclear warhead produced starting in 1963 which saw service until 1993, on the Minuteman I and II ICBMs . The W56 was manufactured in a series of models, all of which were approximately the same size and had a 1.2 megaton yield. The Mod-1, Mod-2, and Mod-3 variants weighed 600 pounds, with the Mod-4 variant weighing 680 pounds. All versions were 17.4 inches (440 mm) diameter by 47.3 inches (1,200 mm) long

Nuclear Weapon Yield
The explosive YIELD OF A NUCLEAR WEAPON is the amount of energy released when that particular nuclear weapon is detonated , usually expressed as a TNT equivalent
TNT equivalent
(the standardized equivalent mass of trinitrotoluene which, if detonated, would produce the same energy discharge), either in kilotons (kt—thousands of tons of TNT), in megatons (Mt—millions of tons of TNT), or sometimes in terajoules (TJ). An explosive yield of one terajoule is 0.239 kt of TNT. Because the accuracy of any measurement of the energy released by TNT has always been problematic, the conventional definition is that one kiloton of TNT is held simply to be equivalent to 1012 calories . The yield-to-weight ratio is the amount of weapon yield compared to the mass of the weapon. The practical maximum yield-to-weight ratio for fusion weapons (thermonuclear weapons ) has been estimated to six megatons of TNT per metric ton of bomb mass (25 TJ/kg)

Physics Package
NUCLEAR WEAPON DESIGNS are physical, chemical, and engineering arrangements that cause the physics package of a nuclear weapon to detonate. There are three existing basic design types. In many existing designs, the explosive energy of deployed devices is derived primarily from nuclear fission , not fusion . (This includes fission of any U-238 tamper or casing due to fusion produced neutrons.) * PURE FISSION WEAPONS were the first nuclear weapons built and have so far been the only type ever used in warfare

Mark 6 Nuclear Bomb
The MARK 6 NUCLEAR BOMB was an American nuclear bomb based on the earlier Mark 4 nuclear bomb
Mark 4 nuclear bomb
and its predecessor, the Mark 3 Fat Man nuclear bomb design. The Mark 6 was in production from 1951 to 1955 and saw service until 1962. Seven variants and versions were produced, with a total production run of all models of 1100 bombs. The basic Mark 6 design was 61 inches (150 cm) in diameter and 128 inches (330 cm) long, the same basic dimensions as the Mark 4 and close to the Mark 3. Various models of the Mark 6 were roughly 25% lighter than either the Mark 4 or Fat Man, and weighed 7,600 to 8,500 pounds (3,400–3,900 kg). Early models of the Mark 6 utilized the same 32-point implosion system design concept as the earlier Mark 4 and Mark 3; the MARK 6 MOD 2 and later used a different, 60-point implosion system. Various models and pit options gave nuclear yields of 8, 26, 80, 154, and 160 kilotons for Mark 6 models

Swan (nuclear Primary)
SWAN was a U.S. test nuclear explosive, which was developed into the XW-45 warhead. It was tested standalone on June 22, 1956 in shot Redwing Inca . It was tested again as the primary of a thermonuclear device on July 2, 1956 in shot Redwing Mohawk . Both tests were successful. It subsequently served as the primary in numerous thermonuclear devices during the 1950s. Most subsequent U.S. primaries are Swan-derived, including the Robin , the Tsetse , the Python , and the much later (asymmetrical) ovoid (prolate) primaries such as the Komodo used in the W88 .
