Shahab-4
The Shahab-4 (, meaning "Meteor-4") (a.k.a. IRIS) was an unbuilt Iranian rocket, derived from the Shahab-3 medium-range ballistic missile. According to Iran it was intended to be a space launch vehicle, after a slip by the Defense Minister in which he acknowledged it as a "more capable ballistic missile than the Shahab-3". According to Western observers, it was intended to be part of a nuclear-capable ballistic missile. History The IRIS/''Shahab-4'' project was initiated in 1988, but according to some sources, it never went beyond the drawing board. The design heritage of the IRIS was later incorporated into the Safir. b14643.de In 1997, an American satellite captured evidence of a Shahab-4 test facility in Parchin. In 1999, it w ...

Shahab-3
The Shahab-3 (; meaning "Meteor-3") is a family of liquid propellant rocket, liquid-fueled ballistic missiles developed by Iran, under the Islamic Revolutionary Guard Corps, IRGC, and based upon the North Korean Nodong-1, Nodong-1/A and Nodong-2, Nodong-B missiles. The Shahab-3 family has a range of 1,000-. It was tested from 1998 to 2003 and added to the military arsenal on 7 July 2003, with an official unveiling by Ayatollah Ali Khamenei, Khamenei on July 20. It has an estimated accuracy of about 2,500m Circular error probable, CEP. According to the IAEA, Iran in the early 2000s may have explored various fuzing, arming and firing systems to make the Shahab-3 more capable of reliably delivering a nuclear warhead. The forerunners to this missile include the Shahab-1 and Shahab-2. Iranian Defense Ministry, Iran's Defense Ministry has alternately denied plans to develop a Shahab-4 and admitted that a Shahab-4 program is in development, having claimed it both to be a Medium-range ba ...

R-12 Dvina
The R-12 Dvina was a theatre ballistic missile developed and deployed by the Soviet Union during the Cold War. Its GRAU designation was 8K63 (8K63U or 8K63У in Cyrillic for silo-launched version), and it was given the NATO reporting name of SS-4 Sandal. The R-12 rocket provided the Soviet Union with the capability to attack targets at medium ranges with a megaton-class thermonuclear warhead and constituted the bulk of the Soviet offensive missile threat to Western Europe. Deployments of the R-12 missile in Cuba caused the Cuban Missile Crisis in 1962. A total of 2335 missiles were produced; all were destroyed in 1993 under the START II treaty. As well as the single-stage ballistic technology, the R-12 Dvina had a two-stage capability that allowed payloads to be placed into low Earth orbit. The Iranian Shahab-4 missile is likely an offshoot of the R-12 Dvina. History Beginning OKB-586 formed from a spin-off of portions of Sergei Korolev's OKB-1 production infrastructure u ...

Ballistic Missile
A ballistic missile is a type of missile that uses projectile motion to deliver warheads on a target. These weapons are powered only during relatively brief periods—most of the flight is unpowered. Short-range ballistic missiles (SRBM) typically stay within the Earth's atmosphere, while most larger missiles travel outside the atmosphere. The type of ballistic missile with the greatest range is an intercontinental ballistic missile (ICBM). The largest ICBMs are capable of full orbital flight. These missiles are in a distinct category from cruise missiles, which are aerodynamically guided in powered flight and thus restricted to the atmosphere. History One modern pioneer ballistic missile was the A-4, commonly known as the V-2, developed by Nazi Germany in the 1930s and 1940s under the direction of Wernher von Braun. The first successful launch of a V-2 was on October 3, 1942, and it began operation on September 6, 1944, against Paris, followed by an attack on London two ...

Space Launch Vehicle
A launch vehicle is typically a rocket-powered vehicle designed to carry a payload (a crewed spacecraft or satellites) from Earth's surface or lower atmosphere to outer space. The most common form is the ballistic missile-shaped multistage rocket, but the term is more general and also encompasses vehicles like the Space Shuttle. Most launch vehicles operate from a launch pad, supported by a launch control center and systems such as vehicle assembly and fueling. Launch vehicles are engineered with advanced aerodynamics and technologies, which contribute to high operating costs. An orbital launch vehicle must lift its payload at least to the boundary of space, approximately and accelerate it to a horizontal velocity of at least . Suborbital vehicles launch their payloads to lower velocity or are launched at elevation angles greater than horizontal. Practical orbital launch vehicles use chemical propellants such as solid fuel, liquid hydrogen, kerosene, liquid oxy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Space
Space is a three-dimensional continuum containing positions and directions. In classical physics, physical space is often conceived in three linear dimensions. Modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as '' spacetime''. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework. In the 19th and 20th centuries mathematicians began to examine geometries that are non-Euclidean, in which space is conceived as '' curved'', rather than '' flat'', as in the Euclidean space. According to Albert Einstein's theory of general relativity, space around gravitational fields deviates from Euclidean space. Experimental tests of general relativity have confirmed that non-Euclidean geometries provide a bet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Safir (rocket)
The Safir (, meaning "ambassador") was the first Iranian expendable launch vehicle able to place a satellite in orbit. The first successful orbital launch using the Safir launch system took place on 2 February 2009 when a Safir carrier rocket placed the Omid satellite into an orbit with a apogee. This made Iran the ninth nation capable of producing and launching a satellite. The Simorgh is a larger orbital launcher based on Safir technology which has since replaced the Safir, and is sometimes called the Safir-2. Design and specifications The Safir measures 1.25 meters in diameter, 22 meters in height and has a launching mass of 26 tons. The rocket consists of two stages; The first stage utilizes an upgraded Nodong/ Shahab-3 type engine which burns a hypergolic combination of UDMH as fuel and nitrogen tetroxide as oxidant, producing 37 tons (363 kN; 82,500 lbf) of thrust. The second stage utilizes a pair of smaller gimballed engines called LRE-4, fed by a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Circle Of Equal Probability
Circular error probable (CEP),Circular Error Probable (CEP), Air Force Operational Test and Evaluation Center Technical Paper 6, Ver 2, July 1987, p. 1 also circular error probability or circle of equal probability, is a measure of a weapon system's precision in the military science of ballistics. It is defined as the radius of a circle, centered on the aimpoint, that is expected to enclose the landing points of 50% of the rounds; said otherwise, it is the median error radius, which is a 50% confidence interval. That is, if a given munitions design has a CEP of 100 m, when 100 munitions are targeted at the same point, an average of 50 will fall within a circle with a radius of 100 m about that point. There are associated concepts, such as the DRMS (distance root mean square), which is the square root of the average squared distance error, a form of the standard deviation. Another is the R95, which is the radius of the circle where 95% of the values would fall, a 9 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
