Al-Samoud 2
Al-Samoud (الصمود, alternately ''Al-Samed'', which means steadfastness in Arabic)Miller, David: ''Conflict Iraq: Weapons and tactics of US and Iraqi Forces.'' Zenith imprint, 2003, page 22. was a liquid-propellant rocket tactical ballistic missile developed by Iraq in the years between the Gulf War and the 2003 Invasion of Iraq. The Iraqi army also developed a solid-fuel rocket version known as Ababil-100. Development The missile was essentially a scaled-down Scud, though parts were mostly derived from the Soviet S-75 Dvina surface-to-air missile. The first test-firing was carried out as early as 1997 and was supervised by UNSCOM. The production started in 2001, and the goal was the assembly of ten missiles each month. The Al Samoud 2 was not fully operational by 2003, but some of them had been already delivered to the Iraqi army. Engine The rocket engine evolved from the S-75 Dvina design and the thrust vector controls from the Scud. The system also included an Iraq ...

Ballistic Missile
A ballistic missile is a type of missile that uses projectile motion to deliver warheads on a target. These weapons are guided only during relatively brief periods—most of the flight is unpowered. Short-range ballistic missiles stay within the Earth's atmosphere, while intercontinental ballistic missiles (ICBMs) are launched on a sub-orbital flight. These weapons are in a distinct category from cruise missiles, which are aerodynamically guided in powered flight. Unlike cruise missiles, which are restricted to the atmosphere, it is advantageous for ballistic missiles to avoid the denser parts of the atmosphere and they may travel above the atmosphere into outer space. History The earliest form of ballistic missile dates from the 13th century with its use derived from the history of rockets. In the 14th century, the Ming Chinese navy used an early form of a ballistic missile weapon called the Huolongchushui in naval battles against enemy ships.Needham, Volume 5, Part 7, ...

Trinitrotoluene
Trinitrotoluene (), more commonly known as TNT, more specifically 2,4,6-trinitrotoluene, and by its preferred IUPAC name 2-methyl-1,3,5-trinitrobenzene, is a chemical compound with the formula C6H2(NO2)3CH3. TNT is occasionally used as a reagent in chemical synthesis, but it is best known as an explosive material with convenient handling properties. The explosive yield of TNT is considered to be the standard comparative convention of bombs and asteroid impacts. In chemistry, TNT is used to generate charge transfer salts. History TNT was first prepared in 1863 by German chemist Julius Wilbrand and originally used as a yellow dye. Its potential as an explosive was not recognized for three decades, mainly because it was too difficult to detonate because it was less sensitive than alternatives. Its explosive properties were first discovered in 1891 by another German chemist, Carl Häussermann. TNT can be safely poured when liquid into shell cases, and is so insensitive that i ...

Baiji, Iraq
Baiji ( ar, بَيْجِي, Bayjī; also spelled Bayji) is a city of about 173,677 inhabitants in northern Iraq. It is located some 130 miles (209 km) north of Baghdad, on the main road to Mosul. It is a major industrial centre best known for its Baiji oil refinery, oil refinery, the biggest in Iraq, and has a large power plant. With regards to transport in the area, Baiji is a junction of the national railway network. History After the invasion of Kuwait in 1990, dozens of British civilians taken captive in Kuwait were held at the Baiji oil refinery, apparently as human shields. The city was bombed during the 1991 Gulf War and about 80% of the oil refinery was destroyed. It was quickly rebuilt and was back in action only a couple of months after the war's end. However, a lack of maintenance and spare parts resulting from the United Nations trade embargo against Iraq caused the deterioration of the city's oil refinery, which by the late 1990s was in a very poor condition and was ...

UNMOVIC
The United Nations Monitoring, Verification and Inspection Commission (UNMOVIC) was created through the adoption of United Nations Security Council resolution 1284 of 17 December 1999 and its mission lasted until June 2007. UNMOVIC was meant to replace the former United Nations Special Commission (UNSCOM) to carry on with the mandate to disarm Iraq of its weapons of mass destruction (WMDs), and to operate a system of ongoing monitoring and verification to check Iraq's compliance with its obligations not to reacquire the same weapons banned by the Security Council. Background and UNMOVIC's predecessor UNSCOM UNSCOM was created with the adoption of United Nations Security Council Resolution 687 in April 1991. Lack of cooperation between UNSCOM and the Iraqi government, plus Saddam Hussein's failure to provide unfettered access to UN arms inspectors, led the United States and the United Kingdom to launch air strikes during Operation Desert Fox. Along with founded suspicion of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
UNSCR 1441
United Nations Security Council Resolution 1441 is a United Nations Security Council resolution adopted unanimously by the United Nations Security Council on 8 November 2002, offering Iraq under Saddam Hussein "a final opportunity to comply with its disarmament obligations" that had been set out in several previous resolutions (Resolutions 660, 661, 678, 686, 687, 688, 707, 715, 986, and 1284). It provided a justification for the subsequent US invasion of Iraq. Resolution 1441 stated that Iraq was in material breach of the ceasefire terms presented under the terms of Resolution 687. Iraq's breaches related not only to weapons of mass destruction (WMD), but also the known construction of prohibited types of missiles, the purchase and import of prohibited armaments, and the continuing refusal of Iraq to compensate Kuwait for the widespread looting conducted by its troops during the 1990–1991 invasion and occupation. It also stated that "...false statements or omiss ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cruise Missile
A cruise missile is a guided missile used against terrestrial or naval targets that remains in the atmosphere and flies the major portion of its flight path at approximately constant speed. Cruise missiles are designed to deliver a large warhead over long distances with high precision. Modern cruise missiles are capable of travelling at high subsonic, supersonic, or hypersonic speeds, are self-navigating, and are able to fly on a non-ballistic, extremely low-altitude trajectory. History The idea of an "aerial torpedo" was shown in the British 1909 film ''The Airship Destroyer'' in which flying torpedoes controlled wirelessly are used to bring down airships bombing London. In 1916, the American aviator Lawrence Sperry built and patented an "aerial torpedo", the Hewitt-Sperry Automatic Airplane, a small biplane carrying a TNT charge, a Sperry autopilot and a barometric altitude control. Inspired by the experiments, the United States Army developed a similar flying bomb cal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silkworm Missile
The SY (), and HY () series were early anti-ship cruise missiles (ASCM) developed by the People's Republic of China from the Soviet P-15 Termit missile. They entered service in the late 1960s and remained the main ASCMs deployed by the People's Liberation Army Navy through the 1980s. The missiles were used by the PRC and export customers to develop land-attack missiles. The name Silkworm is popularly used for the entire SY and HY family. As a NATO reporting name it applies only to the land-based variant of the HY-1. Development Chinese preparations were underway before receiving the first P-15s and related technical data from the Soviets in 1959. On 8 October 1956, the Fifth Academy was founded - with Qian Xuesen as director - to pursue missile development, and in March 1958 a cruise missile test site was selected at Liaoxi in Liaoning. The first successful missile test was conducted in November 1960 after the withdrawal of Soviet advisors in September due to the Sino-Soviet s ...

Gyroscopes
A gyroscope (from Ancient Greek γῦρος ''gŷros'', "round" and σκοπέω ''skopéō'', "to look") is a device used for measuring or maintaining orientation and angular velocity. It is a spinning wheel or disc in which the axis of rotation (spin axis) is free to assume any orientation by itself. When rotating, the orientation of this axis is unaffected by tilting or rotation of the mounting, according to the conservation of angular momentum In physics, angular momentum (rarely, moment of momentum or rotational momentum) is the rotational analog of linear momentum. It is an important physical quantity because it is a conserved quantity—the total angular momentum of a closed system .... Gyroscopes based on other operating principles also exist, such as the microchip-packaged Vibrating structure gyroscope#MEMS gyroscopes, MEMS gyroscopes found in electronic devices (sometimes called gyrometers), solid-state ring laser gyroscope, ring lasers, fibre optic gyroscopes, an ...
