Advena
Advena is a South African nuclear weapons production facility, having been transferred in 1979 from the Pelindaba nuclear research center to the state-owned Armaments Corporation of South Africa ( Armscor), was later developed as the Kentron Circle facility. This facility, built in 1980, and located west of Pretoria, was subsequently renamed Advena. Nuclear family At Pelindaba, Nuclear weapons of the gun-type design were developed. Armscor established a production line there in 1981 and produced at least one nuclear device of a 10-18 kilotons yield each year. Extended family Advena Central Laboratories were constructed in the mid-1980s to extend South Africa's nuclear capabilities from gun-type weapons to inter-continental ballistic missile (ICBM) delivery platforms. Work to produce advanced warhead designs was also developed. Working with Israel at Advena, a 2000 km-range missile – based on the Jericho II ICBM – was designed and tested. The construction o ...

Nuclear Weapon
A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or a combination of fission and fusion reactions ( thermonuclear bomb), producing a nuclear explosion. 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 . The first thermonuclear ("hydrogen") bomb test released energy approximately equal to . Nuclear bombs have had yields between 10 tons TNT (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). A thermonuclear weapon weighing as little as can release energy equal to more than . A nuclear device no larger than a conventional bomb 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. Nuclear weapons have been dep ...

Armaments
A weapon, arm or armament is any implement or device that can be used to deter, threaten, inflict physical damage, harm, or kill. Weapons are used to increase the efficacy and efficiency of activities such as hunting, crime, law enforcement, self-defense, warfare, or suicide. In broader context, weapons may be construed to include anything used to gain a tactical, strategic, material or mental advantage over an adversary or enemy target. While ordinary objects – sticks, rocks, bottles, chairs, vehicles – can be used as weapons, many objects are expressly designed for the purpose; these range from simple implements such as clubs, axes and swords, to complicated modern firearms, tanks, intercontinental ballistic missiles, biological weapons, and cyberweapons. Something that has been re-purposed, converted, or enhanced to become a weapon of war is termed weaponized, such as a weaponized virus or weaponized laser. History The use of weapons is a major driver of cul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vela Incident
The Vela incident was an unidentified double flash of light detected by an American Vela Hotel satellite on 22 September 1979 near the South African territory of Prince Edward Islands in the Indian Ocean, roughly midway between Africa and Antarctica. Today, most independent researchers believe that the flash was caused by a nuclear explosion—an undeclared joint nuclear test carried out by South Africa and Israel. The cause of the flash remains officially unknown, and some information about the event remains classified by the U.S. government. While it has been suggested that the signal could have been caused by a meteoroid hitting the satellite, the previous 41 double flashes detected by the Vela satellites were caused by nuclear weapons tests. Detection The " double flash", then dubbed the South Atlantic flash, was detected on 22 September 1979, at 00:53 UTC, by the American Vela satellite OPS 6911 (also known as Vela 10 and Vela 5B), which carried various sensors desig ...

South Africa And Weapons Of Mass Destruction
From the 1960s to the 1990s, South Africa pursued research into weapons of mass destruction, including nuclear, biological, and chemical weapons under the apartheid government. Six nuclear weapons were assembled. South African strategy was, if political and military instability in Southern Africa became unmanageable, to conduct a nuclear weapon test in a location such as the Kalahari desert, where an underground testing site had been prepared, to demonstrate its capability and resolve—and thereby highlight the peril of intensified conflict in the region—and then invite a larger power such as the United States to intervene. Before the anticipated changeover to a majority-elected African National Congress–led government in the 1990s, the South African government dismantled all of its nuclear weapons, the first state in the world which voluntarily gave up all nuclear arms it had developed itself. The country has been a signatory of the Biological Weapons Convention since 19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South African General Election, 1994
General elections were held in South Africa between 26 and 29 April 1994. The elections were the first in which citizens of all races were allowed to take part, and were therefore also the first held with universal suffrage. The election was conducted under the direction of the Independent Electoral Commission (IEC), and marked the culmination of the four-year process that ended apartheid. Millions queued in lines over a four-day voting period. Altogether, 19,726,579 votes were counted, and 193,081 were rejected as invalid. As widely expected, the African National Congress (ANC), whose slate incorporated the labour confederation COSATU and the South African Communist Party, won a sweeping victory, taking 62 percent of the vote, just short of the two-thirds majority required to unilaterally amend the Interim Constitution. As required by that document, the ANC formed a Government of National Unity with the National Party and the Inkatha Freedom Party, the two other parties th ...

Nelson Mandela
Nelson Rolihlahla Mandela (; ; 18 July 1918 – 5 December 2013) was a South African anti-apartheid activist who served as the first president of South Africa from 1994 to 1999. He was the country's first black head of state and the first elected in a fully representative democratic election. His government focused on dismantling the legacy of apartheid by fostering racial reconciliation. Ideologically an African nationalist and socialist, he served as the president of the African National Congress (ANC) party from 1991 to 1997. A Xhosa, Mandela was born into the Thembu royal family in Mvezo, Union of South Africa. He studied law at the University of Fort Hare and the University of Witwatersrand before working as a lawyer in Johannesburg. There he became involved in anti-colonial and African nationalist politics, joining the ANC in 1943 and co-founding its Youth League in 1944. After the National Party's white-only government established apartheid, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jericho Missile
Jericho is a general designation given to a loosely-related family of deployed ballistic missiles developed by Israel starting in the 1960s. The name is taken from the first development contract for the Jericho I signed between Israel and Dassault in 1963, with the codename as a reference to the Biblical city of Jericho. As with most Israeli unconventional weapons systems, exact details are classified, though there are observed test data, public statements by government officials, and details in open literature especially about the Shavit satellite launch vehicle. The later Jericho family development is related to the Shavit and Shavit II space launch vehicles believed to be derivatives of the Jericho II IRBM and that preceded the development of the Jericho III ICBM. The Lawrence Livermore National Laboratory in the US concluded that the Shavit could be adapted as an ICBM carrying a 500 kg warhead over 7,500 km. Additional insight into the Jericho program was revealed b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guided Missile
In military terminology, a missile is a guided airborne ranged weapon capable of self-propelled flight usually by a jet engine or rocket motor. Missiles are thus also called guided missiles or guided rockets (when a previously unguided rocket is made guided). Missiles have five system components: targeting, guidance system, flight system, engine and warhead. Missiles come in types adapted for different purposes: surface-to-surface and air-to-surface missiles ( ballistic, cruise, anti-ship, anti-submarine, anti-tank, etc.), surface-to-air missiles (and anti-ballistic), air-to-air missiles, and anti-satellite weapons. Airborne explosive devices without propulsion are referred to as shells if fired by an artillery piece and bombs if dropped by an aircraft. Unguided jet- or rocket-propelled weapons are usually described as rocket artillery. Historically, the word ''missile'' referred to any projectile that is thrown, shot or propelled towards a target; this usage is still ...

Warhead
A warhead is the forward section of a device that contains the explosive agent or toxic (biological, chemical, or nuclear) material that is delivered by a missile, rocket, torpedo, or bomb. Classification Types of warheads include: *Explosive: An explosive charge is used to disintegrate the target, and damage surrounding areas with a blast wave. ** Conventional: Chemicals such as gunpowder and high explosives store significant energy within their molecular bonds. This energy can be released quickly by a trigger, such as an electric spark. Thermobaric weapons enhance the blast effect by utilizing the surrounding atmosphere in their explosive reactions. *** Blast: A strong shock wave is provided by the detonation of the explosive. ***Fragmentation: Metal fragments are projected at high velocity to cause damage or injury. ***Continuous rod: Metal bars welded on their ends form a compact cylinder of interconnected rods, which is violently expanded into a contiguous zig-zag ...

Inter-continental Ballistic Missile
An intercontinental ballistic missile (ICBM) is a ballistic missile with a range greater than , primarily designed for nuclear weapons delivery (delivering one or more thermonuclear warheads). Conventional, chemical, and biological weapons can also be delivered with varying effectiveness, but have never been deployed on ICBMs. Most modern designs support multiple independently targetable reentry vehicles (MIRVs), allowing a single missile to carry several warheads, each of which can strike a different target. Russia, the United States, China, France, India, the United Kingdom, and North Korea are the only countries known to have operational ICBMs. Early ICBMs had limited precision, which made them suitable for use only against the largest targets, such as cities. They were seen as a "safe" basing option, one that would keep the deterrent force close to home where it would be difficult to attack. Attacks against military targets (especially hardened ones) still demanded the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
