W33 (nuclear Weapon)
The W33 (also known as the Mark 33, T317 and M422) was an American nuclear artillery shell designed for use in the M110 howitzer and M115 howitzer. A total of 2,000 W33 projectiles were produced, with the first production warheads entering the stockpile in 1957. The W33 remained in service until 1992. The warhead used enriched uranium (code named ''oralloy'') as its nuclear fissile material and could be used in two different yield configurations. This required the assembly and insertion of different pits, with the amount of fissile materials used controlling whether the destructive yield was low or high. The highest-yield version of the W33 may have been a boosted fission weapon. History Development of the W33 was authorized by the Army Ordnance Corps in June 1953. It was believed that a shell capable of being fired by a standard mobile field howitzer would be more effective while also providing a psychological effect in ground warfare. The design would also include considera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Artillery
Nuclear artillery is a subset of limited- yield tactical nuclear weapons, in particular those weapons that are launched from the ground at battlefield targets. Nuclear artillery is commonly associated with shells delivered by a cannon, but in a technical sense short-range artillery rockets or tactical ballistic missiles are also included. The development of nuclear artillery was part of a broad push by nuclear weapons countries to develop nuclear weapons which could be used tactically against enemy armies in the field (as opposed to strategic uses against cities, military bases, and heavy industry). Nuclear artillery was both developed and deployed by a small group of states, including the United States, the Soviet Union, and France. The United Kingdom planned and partially developed such weapon systems (the Blue Water missile and the Yellow Anvil artillery shell) but did not put them into production. A second group of states has derivative association with nuclear artille ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

W79 Artillery-Fired Atomic Projectile
The W79 Artillery-Fired Atomic Projectile (AFAP), also known as the XM753 (Atomic RA) was an American nuclear artillery shell, capable of being fired from any NATO howitzer e.g. the M115 and M110 howitzer. Produced in two models, the enhanced radiation W79 Mod 0 and fission-only W79 Mod 1. Both were plutonium-based linear- implosion nuclear weapons. * The Mod 0 was a variable yield device with three yields, ranging from up to and an enhanced-radiation mode which could be turned on or off * The Mod 1 was fission-only with a fixed yield, corresponding with the maximum fission only yield of the ''Mod 0'' Both models were in diameter, long and weighed . The W79 was developed by Lawrence Livermore National Laboratory, starting in 1975. Production of the different mods took place from July 1981 through August 1986. A total of 550 warheads (325 Mod 0s, 225 Mod 1s) were produced. All units were retired from active service by the end of 1992 with the last shell dismantled at the P ...

List Of Nuclear Weapons
This is a list of nuclear weapons listed according to country of origin, and then by type within the states. United States US nuclear weapons of all types – bombs, warheads, shells, and others – are numbered in the same sequence starting with the Mark 1 and () ending with the W-91 (which was canceled prior to introduction into service). All designs which were formally intended to be weapons at some point received a number designation. Pure test units which were experiments (and not intended to be weapons) are not numbered in this sequence. Early weapons were very large and could only be used as free fall bombs. These were known by "Mark" designators, like the Mark 4 which was a development of the Fat Man weapon. As weapons became more sophisticated they also became much smaller and lighter, allowing them to be used in many roles. At this time the weapons began to receive designations based on their role; bombs were given the prefix "B", while the same warhead used in other r ...

Upshot-Knothole Grable
Upshot–Knothole ''Grable'' was a nuclear weapons test conducted by the United States as part of Operation Upshot–Knothole. Detonation of the associated nuclear weapon occurred 19 seconds after its deployment at 8:30am PDT (1530 UTC) on May 25, 1953, in Area 5 of the Nevada Test Site. Nuclear weapons test The codename ''Grable'' was chosen because the letter ''Grable'' is phonetic for G, as in "gun", since the warhead was a gun-type fission weapon. As a shell, or artillery-fired atomic projectile (AFAP), the device was the first of its kind. The test remains the only nuclear artillery shell ever actually fired in the U.S. nuclear weapons test program. ''Grable'' was the second of only four gun-type warheads ever detonated (the first was Little Boy, the weapon used against Hiroshima, the last two were test firings of the W33; all other atomic weapons were implosion-type weapons). The shell, designated a Mark 9 nuclear weapon, had a diameter of 280 mm (11.02 in), was 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
W9 (nuclear Warhead)
The W9 was an American nuclear artillery shell fired from a special howitzer. It was produced starting in 1952 and all were retired by 1957, being superseded by the W19. Description The W9 was in diameter, long, and weighed . It had an explosive yield of . The W9 was a gun-type nuclear weapon, using around of highly enriched uranium in one large rings assembly and one smaller ''bullet'', which was fired down a tube by conventional explosives into the rings assembly to achieve critical mass and detonate the weapon. The W9 units which were retired in 1957 were recycled into lower yield T-4 Atomic Demolition Munitions. These were the first (semi) man-portable nuclear weapons. Tests The W9 is only the second gun-type nuclear weapon known to have been detonated; the first was the Little Boy nuclear weapon used in World War II. The W9 artillery shell was test fired once, fired from the "Atomic Annie" M65 Atomic Cannon, in ''Upshot-Knothole Grable'' on May 25, 1953 at the ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atomic Bombings Of Hiroshima And Nagasaki
The United States detonated two atomic bombs over the Japanese cities of Hiroshima and Nagasaki on 6 and 9 August 1945, respectively. The two bombings killed between 129,000 and 226,000 people, most of whom were civilians, and remain the only use of nuclear weapons in armed conflict so far. In the final year of World War II, the Allies prepared for a costly invasion of the Japanese mainland. This undertaking was preceded by a conventional and firebombing campaign that devastated 64 Japanese cities. The war in the European theatre concluded when Germany surrendered on 8 May 1945, and the Allies turned their full attention to the Pacific War. By July 1945, the Allies' Manhattan Project had produced two types of atomic bombs: "Fat Man", a plutonium implosion-type nuclear weapon; and "Little Boy", an enriched uranium gun-type fission weapon. The 509th Composite Group of the United States Army Air Forces was trained and equipped with the specialized Silverplate version of the ...

Little Boy
"Little Boy" was the type of atomic bomb dropped on the Japanese city of Hiroshima on 6 August 1945 during World War II, making it the first nuclear weapon used in warfare. The bomb was dropped by the Boeing B-29 Superfortress ''Enola Gay'' piloted by Colonel Paul W. Tibbets, Jr., commander of the 509th Composite Group of the United States Army Air Forces and Captain Robert A. Lewis. It exploded with an energy of approximately and caused widespread death and destruction throughout the city. The Hiroshima bombing was the second man-made nuclear explosion in history, after the Trinity nuclear test. Little Boy was developed by Lieutenant Commander Francis Birch (geophysicist), Francis Birch's group at the Manhattan Project's Los Alamos Laboratory during World War II, a reworking of their unsuccessful Thin Man (nuclear bomb), Thin Man nuclear bomb. Like Thin Man, it was a gun-type fission weapon, but it derived its explosive power from the nuclear fission of uranium-235, where ...

Operation Plumbbob
Operation Plumbbob was a series of nuclear tests that were conducted between May 28 and October 7, 1957, at the Nevada Test Site, following ''Project 57'', and preceding '' Project 58/58A''. Background 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. They included forty-three military effects tests on civil and military structures, radiation and bio-medical studies, and aircraft structural tests. ''Operation Plumbbob'' had the tallest tower tests to date in the U.S. nuclear testing program as well as high-altitude balloon tests. One nuclear test involved the largest troop maneuver ever associated with U.S. nuclear testing. Approximately 18,000 members of t ...

Operation Nougat
Operation Nougat was a series of 44 nuclear tests conducted (with one exception) at the Nevada Test Site in 1961 and 1962, immediately after the Soviet Union abrogated a testing moratorium, with the US' ''Mink'' test shot taking place the day before the Soviets test-detonated the Tsar Bomba. Most tests were limited-yield underground test shots. New designs would be further developed in atmospheric testing during ''Operation Dominic I and II''. ''Operation Dominic I and II'' would follow ''Operation Nougat'', with some testing overlap. ''Operation Hardtack II'' preceded Nougat and the testing moratorium. Tests Antler Antler was the first shot fired as part of the resumption of nuclear testing by the United States. Fired 15 September 1958, containment was immediately lost when the shot vented via the tunnel portal, destroying much of the test data. This was a recurring problem for tunnel tests of the era. The problem was thought to be caused by water above the blast zone drainin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
