Degelen Omega
Degelen () is a mountain massif in the Zhanasemey District, Abai Region, Kazakhstan.''Kazakhstan National Encyclopedia'' / Ch. ed. B.O. Jakyp. — Almaty: « Kazakh encyclopedia» ZhSS, 2011. ISBN 9965-893-64-0 (T.Z.), ISBN 9965-893-19-5 Semey city, former Semipalatinsk, lies about to the ENE of the Degelen mountain area. The Balapan nuclear test site lies to the northeast. History At the time of the Kazakh SSR Degelen was part of the Semipalatinsk Test Site complex. Around hundred horizontal tunnels were bored into the mountain to carry out nuclear tests operated by the USSR armed forces. The mountain massif was the location chosen for the majority of the subcritical and supercritical tests. 215 underground nuclear explosions were carried out. In 1991, following the dissolution of the Soviet Union, the site was taken over by the government of Kazakhstan. The tunnels were closed in 1993. The abandoned electrical installations and the rails that had been used to transport the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Partial Nuclear Test Ban Treaty
The Partial Test Ban Treaty (PTBT), formally known as the 1963 Treaty Banning Nuclear Weapon Tests in the Atmosphere, in Outer Space and Under Water, prohibited all nuclear weapons testing, test detonations of nuclear weapons except for those conducted underground nuclear weapons testing, underground. It is also abbreviated as the Limited Test Ban Treaty (LTBT) and Nuclear Test Ban Treaty (NTBT), though the latter may also refer to the Comprehensive Nuclear-Test-Ban Treaty (CTBT), which succeeded the PTBT for ratifying parties. Negotiations initially focused on a comprehensive ban, but that was abandoned because of technical questions surrounding the detection of underground tests and Soviet concerns over the intrusiveness of proposed verification methods. The impetus for the test ban was provided by rising public anxiety over the magnitude of nuclear tests, particularly tests of new thermonuclear weapons (hydrogen bombs), and the resulting nuclear fallout. A test ban was also se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frenchman Flat
Frenchman Flat is a hydrographic basin in the Nevada National Security Site south of Yucca Flat and north of Mercury, Nevada. The flat was used as an American nuclear test site and has a dry lake bed (Frenchman Lake) that was used as a 1950s airstrip before it was chosen after the start of the Korean War for the Nevada Proving Grounds. Nellis Air Force Base land was transferred to the Atomic Energy Commission on which Site Mercury was constructed on the flat for supporting American nuclear explosive tests. The 1951 Operation Ranger "Able" test (ground zero at UTM Coordinates 923758 on the flat) was the first continental US nuclear detonation after the 1945 Trinity test, and Frenchman Flat also had the only detonation of an American artillery-fired nuclear projectile in the 1953 Upshot-Knothole Grable test using the M65 Atomic Cannon.

Nevada Test And Training Range
The Nevada Test and Training Range (NTTR) is one of two military training areas at the Nellis Air Force Base Complex in Nevada and used by the United States Air Force Warfare Center at Nellis Air Force Base. The NTTR land area includes a "simulated Integrated Air Defense System", several individual ranges with 1200 targets, and 4 remote communication sites. The current NTTR area and the range's former areas have been used for aerial gunnery and bombing, for nuclear tests, as a proving ground and flight test area, for aircraft control and warning, and for Blue Flag, Green Flag, and Red Flag exercises. Geography The Nevada Test and Training Range land area is mostly Central Basin and Range ecoregion (cf. southernmost portion in the Mojave Desert), and smaller ecoregions (e.g., Tonopah Basin, Tonopah Playa, and Bald Mountain biomes) are within the area of numerous basin and range landforms of the NTTR.

Nevada Test Site
The Nevada National Security Sites (N2S2 or NNSS), popularized as the Nevada Test Site (NTS) until 2010, is a reservation of the United States Department of Energy located in the southeastern portion of Nye County, Nevada, about northwest of the city of Las Vegas. Formerly known as the Nevada Proving Grounds of the United States Army, the site was acquired in 1951 to be the testing venue for the American nuclear devices. The first atmospheric test was conducted at the site's Frenchman Flat area by the United States Atomic Energy Commission (USAEC) on January 27, 1951. About 928 nuclear tests were conducted here through 1994, when the United States stopped its underground nuclear testing. The site consists of about of desert and mountainous terrain. Some 1,100 buildings in 28 areas are connected by of paved roads, of unpaved roads, ten heliports, and two airstrips. The site is privately managed and operated by Mission Support and Test Services LLC, a joint venture of H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operation Grapple
Operation Grapple was a set of four series of British nuclear weapons tests of early atomic bombs and hydrogen bombs carried out in 1957 and 1958 at Malden Island and Kiritimati (Christmas Island) in the Gilbert and Ellice Islands in the Pacific Ocean (modern Kiribati) as part of the British hydrogen bomb programme. Nine nuclear explosions were initiated, culminating in the United Kingdom becoming the third recognised possessor of thermonuclear weapons, and the restoration of the nuclear Special Relationship with the United States in the form of the 1958 US–UK Mutual Defence Agreement. During the Second World War, Britain had a nuclear weapons project, codenamed Tube Alloys, which was merged with the American Manhattan Project in August 1943. Many of Britain's top scientists participated in the Manhattan Project. After the war, fearing that Britain would lose its great power status, the British government resumed the atomic bomb development effort, now codenamed High E ...

Kiritimati
Kiritimati (), also known as Christmas Island, is a Pacific Ocean atoll in the northern Line Islands. It is part of the Republic of Kiribati. The name is derived from the English word "Christmas" written in Gilbertese according to its phonology, in which the combination is pronounced /s/. Kiritimati is one of the world's largest atolls in terms of land area, consisting of about land area and a network of lagoons;. The atoll is about in perimeter, while the lagoon shoreline extends for over . Kiritimati comprises over 70% of the total land area of Kiribati, a country encompassing 33 Pacific atolls and islands. It lies north of the equator, south of Honolulu, and from San Francisco. Kiritimati is in the world's furthest forward time zone, UTC+14, and is therefore one of the first inhabited places on Earth to experience New Year's Day (see also Caroline Atoll, Kiribati). Although it lies east of the 180th meridian, the Republic of Kiribati realigned the International ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operation Fishbowl
Operation Fishbowl was a series of high-altitude nuclear explosion, high-altitude nuclear tests in 1962 that were carried out by the United States as a part of the larger Operation Dominic I and II, Operation Dominic nuclear test program. Introduction The Operation Fishbowl nuclear tests were originally to be completed during the first half of 1962 with three tests named ''Bluegill, Starfish'' and ''Urraca''. The first test attempt was delayed until June. Planning for Operation Fishbowl, as well as many other nuclear tests in the region, began rapidly in response to the sudden Soviet Union, Soviet announcement on August 30, 1961, that they were ending a three-year moratorium on nuclear testing. The rapid planning of very complex operations necessitated many changes as the project progressed. All of the tests were to be launched on missiles from Johnston Island in the Pacific Ocean north of the equator. Johnston Island had already been established as a launch site for United ...

Operation Hardtack II
Operation Hardtack II was a series of 37 nuclear tests conducted by the United States in 1958 at the Nevada Test Site. These tests followed the ''Operation Argus'' series and preceded the ''Operation Nougat'' series. With test moratoriums on the horizon, American weapons labs rushed out many new designs. A hard deadline for testing was set at midnight (0000 hrs), 31 October 1958, as negotiations were set to start that day, and the schedule shows it, with 29 tests executed in October, four of them on the last day. One other test was cancelled because weather delays postponed it across the midnight deadline. After the conclusion of Hardtack II, the United States announced a unilateral testing moratorium, which the Soviet Union joined after two last tests on 1 and 3 November. In September 1961, the Soviet Union resumed nuclear testing — including the test of the most powerful nuclear device ever designed, the ''Tsar Bomba'', in October — and the United States followed suit ...

Operation Dominic
Operation Dominic was a series of 31 nuclear test explosions ("shots") with a total yield conducted in 1962 by the United States in the Pacific. This test series was scheduled quickly, in order to respond in kind to the Soviet resumption of testing after the tacit 1958–1961 test moratorium. Most of these shots were conducted with free fall bombs dropped from B-52 bomber aircraft. Twenty of these shots were to test new weapons designs; six to test weapons effects; and several shots to confirm the reliability of existing weapons. The Thor missile was also used to lift warheads into near-space to conduct high-altitude nuclear explosion tests; these shots were collectively called Operation Fishbowl. Operation Dominic occurred during a period of high Cold War tension between the United States and the Soviet Union, since the Cuban Bay of Pigs Invasion had occurred not long before. Nikita Khrushchev announced the end of a three-year moratorium on nuclear testing on 30 Augus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
