Dongfeng 3
The DF-3A (NATO: CSS-2) is a Chinese liquid-fueled, single-stage, nuclear medium-range ballistic missile that entered service in 1971.Chinese nuclear forces, 2010. Bulletin of the Atomic Scientists. In 1988 China sold several dozen (reportedly between 36 and 60) DF-3A missiles to Saudi Arabia. Saudi Arabia publicly displayed them for the first time in 2014. History Deployment of the missile began in 1971, reaching a peak of 110 by 1984, then shrinking to 50 in 1993. It was estimated by the U.S. DoD that there were 17 missiles and 10 launchers in operation as of 2010 under a single brigade. By May 2014, it appeared that the last unit operating the DF-3A completed conversion to the DF-21 missile from satellite photos of changes to the launch unit site. - Fas.org, 21 May 2 ...

IRBM
An intermediate-range ballistic missile (IRBM) is a ballistic missile with a range of 3,000–5,500 km (1,864–3,418 miles), between a medium-range ballistic missile (MRBM) and an intercontinental ballistic missile (ICBM). Classifying ballistic missiles by range is done mostly for convenience; in principle there is very little difference between a low-performance ICBM and a high-performance IRBM, because decreasing payload mass can increase range over ICBM threshold. The range definition used here is used within the U.S. Missile Defense Agency. Some other sources include an additional category, the long-range ballistic missile (LRBM), to describe missiles with a range between IRBMs and true ICBMs. The more modern term theatre ballistic missile encompasses MRBMs and SRBMs, including any ballistic missile with a range under . The progenitor for the IRBM was the A4b winged rocket, based on the V-2 (officially called A4) rocket used by Nazi Germany at the end of World War I ...

Astro-inertial Guidance
Missile guidance refers to a variety of methods of guiding a missile or a guided bomb to its intended target. The missile's target accuracy is a critical factor for its effectiveness. Guidance systems improve missile accuracy by improving its Probability of Guidance (Pg). These guidance technologies can generally be divided up into a number of categories, with the broadest categories being "active", "passive", and "preset" guidance. Missiles and guided bombs generally use similar types of guidance system, the difference between the two being that missiles are powered by an onboard engine, whereas guided bombs rely on the speed and height of the launch aircraft for propulsion. History The concept of unmanned guidance originated at least as early as World War I, with the idea of remotely guiding an airplane bomb onto a target, such as the systems developed for the first powered drones by Archibald Low (The Father of Radio Guidance). In World War II, guided missiles were first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Circular Error Probable
In the military science of ballistics, circular error probable (CEP) (also circular error probability or circle of equal probability) is a measure of a weapon system's precision. It is defined as the radius of a circle, centered on the mean, whose perimeter is expected to include the landing points of 50% of the rounds; said otherwise, it is the median error radius. That is, if a given munitions design has a CEP of 100 m, when 100 munitions are targeted at the same point, 50 will fall within a circle with a radius of 100 m around their average impact point. (The distance between the target point and the average impact point is referred to as bias.) There are associated concepts, such as the DRMS (distance root mean square), which is the square root of the average squared distance error, and R95, which is the radius of the circle where 95% of the values would fall in. The concept of CEP also plays a role when measuring the accuracy of a position obtained by a navigati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Liquid-propellant Rocket
A liquid-propellant rocket or liquid rocket utilizes a rocket engine that uses liquid rocket propellant, liquid propellants. Liquids are desirable because they have a reasonably high density and high Specific impulse, specific impulse (''I''sp). This allows the volume of the propellant tanks to be relatively low. It is also possible to use lightweight centrifugal turbopumps to pump the rocket propellant from the tanks into the combustion chamber, which means that the propellants can be kept under low pressure. This permits the use of low-mass propellant tanks that do not need to resist the high pressures needed to store significant amounts of gasses, resulting in a low mass ratio for the rocket. An inert gas stored in a tank at a high pressure is sometimes used instead of pumps in simpler small engines to force the propellants into the combustion chamber. These engines may have a higher mass ratio, but are usually more reliable, and are therefore used widely in satellites for orbit ...

DF-21
The Dong-Feng 21 (DF-21; NATO reporting name CSS-5 - Dong-Feng () is a two-stage, solid-fuel rocket, single-warhead medium-range ballistic missile (MRBM) in the Dong Feng series developed by China Changfeng Mechanics and Electronics Technology Academy. Development started in the late 1960s and was completed around 1985–86, but it was not deployed until 1991. It was developed from the submarine-launched JL-1 missile, and is China's first solid-fuel land-based missile. The U.S. Department of Defense in 2008 estimated that China had 60-80 missiles and 60 launchers; approximately 10-11 missiles can be built annually. Originally developed as a strategic weapon, the DF-21's later variants were designed for both nuclear and conventional missions. It is thought able to carry a high explosive, submunition, or 300 kt nuclear warhead. The latest DF-21D was said to be the world's first anti-ship ballistic missile (ASBM). The DF-21 has also been developed into a space-capable anti-sate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Royal Saudi Strategic Missile Force
The Royal Saudi Strategic Missile Force ( ar, قوة الصواريخ الإستراتيجية الملكية السعودية) or RSSMF is the fifth branch of the Saudi Arabian Armed Forces, responsible for commissioning long-range strategic missiles. The RSSMF formerly had its headquarters in an underground command facility in Riyadh– the capital of Saudi Arabia. The facility coordinated Saudi Arabia's advanced "Peace Shield" radar and air defense systems. In July 2013, the new RSSMF headquarters and academy buildings were officially opened by Prince Khalid bin Sultan bin Abdulaziz and current RSSMF commander Lieutenant general Jarallah Alaluwayt. History The RSSMF's role has grown rapidly since Saudi Arabia and other Arab States of the Persian Gulf announced in 2009 an initiative to obtain nuclear weapons as a countermeasure to the Iranian nuclear program.

DF-4
The Dong Feng 4 () or DF-4 (also known as the CSS-3) is a first-generation two-stage Chinese intercontinental ballistic missile with liquid fuel (Nitric acid/Unsymmetrical dimethylhydrazine). It was thought to be deployed in limited numbers in underground silos beginning in the late 1970s and early 1980s. The Dong Feng 4 has a takeoff thrust of 1,224.00 kN, a takeoff weight of 82000 kg, a diameter of 2.25 m, a length of 28.05 m and a fin span of 2.74 m. The range of the Dong Feng 4, which is equipped with a 2,190 kg nuclear warhead with 3.3 Megaton yield, with a nominal range of 5,500 km. This gives it sufficient range to strike targets as far away as Russia, India, and American bases in the Pacific. The missile uses an inertial guidance system, resulting in a large CEP of 1,500 meters. As of 2017, 10–15 launchers are deployed. History The decision to develop the DF-4 was made in 1965 in response to the U.S. ballistic missile submarine patrols that be ...
