BGM-109
The Tomahawk () Land Attack Missile (TLAM) is a long-range, all-weather, jet-powered, subsonic cruise missile that is primarily used by the United States Navy and Royal Navy in ship and submarine-based land-attack operations. Under contract from the U.S. Navy, the Tomahawk was designed at the APL/JHU in a project led by James Walker near Laurel, Maryland, and was first manufactured by General Dynamics in the 1970s. It was intended to fill the role of a medium- to long-range, low-altitude missile that could be launched from a naval surface warfare platform, and featured a modular design accommodating a wide variety of warhead, guidance, and range capabilities. At least six variants and multiple upgraded versions of the TLAM have been added since the original design was introduced, including air-, sub-, and ground-launched variants with conventional and nuclear armaments. In 1992–1994, McDonnell Douglas Corporation was the sole supplier of Tomahawk Missiles and produced Block II ... [...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] |
W80 (nuclear Warhead)
The W80 is a low to intermediate yield two-stage thermonuclear warhead deployed by the U.S. Enduring Stockpile, enduring stockpile with a variable yield ("dial-a-yield") of . It was designed for deployment on cruise missiles and is the warhead used in all nuclear-armed AGM-86, ALCM and AGM-129 ACM, ACM missiles deployed by the US Air Force, and in the US Navy's BGM-109 Tomahawk. It is essentially a modification of the widely deployed B61 nuclear bomb, B61 weapon, which forms the basis of most of the current US stockpile (military), stockpile of nuclear gravity bombs. The very similar W84 warhead was deployed on the retired BGM-109G Ground Launched Cruise Missile. Dimensions The W80 is physically quite small: the physics package itself is about the size of a conventional Mark 81 bomb, Mk.81 bomb, in diameter and long, and only slightly heavier at about . History Early development The Los Alamos National Laboratory began development on the W80 in June 1976, with the brief of ...

Land-attack Missile
A land-attack missile (LAM) is a naval surface-to-surface missile that is capable of effectively attacking targets ashore, unlike specialized anti-ship missiles, which are optimized for striking other ships. Some dual-role missiles are suitable for both missions. Like long-range anti-ship missiles, land-attack missiles are usually turbojet or turbofan powered cruise missiles. To prevent early detection and counter-measures, they usually fly near the ground at very low altitude, employing terrain-following techniques, either with terrain-following radar or with precise navigation system, like Global Positioning System, GPS, combined with a stored map of obstacles and ground elevation data (TERCOM). Land-attack missiles are usually programmed before launch to follow a set of waypoints up to the target. Terminal guidance can be done with active radar homing, passive radar or Electronic warfare support measures, infrared homing or optical guidance, or the (fixed) target was predesign ...

DSMAC
Terrain contour matching, or TERCOM, is a navigation system used primarily by cruise missiles. It uses a pre-recorded contour map of the terrain that is compared with measurements made during flight by an on-board radar altimeter. A TERCOM system considerably increases the accuracy of a missile compared with inertial navigation systems (INS). The increased accuracy allows a TERCOM-equipped missile to fly closer to obstacles and generally lower altitudes, making it harder to detect by ground radar. Description Optical contour matching The Goodyear Aircraft Corporation ATRAN (''Automatic Terrain Recognition And Navigation'') system for the MGM-13 Mace was the earliest known TERCOM system. In August 1952, Air Materiel Command initiated the mating of the Goodyear ATRAN with the MGM-1 Matador. This mating resulted in a production contract in June 1954. ATRAN was difficult to jam and was not range-limited by line-of sight, but its range was restricted by the availability of radar ma ...

BLU-97/B Combined Effects Bomb
The BLU-97/B Combined Effects Bomb is the submunition used in several cluster bomb type weapon systems, mainly the CBU-87 and its precision-guided version CBU-103. When the bomblets fall, they separate from the main bomb and independently free fall to the ground. They contain an inflatable bag (ballute) on the top of them, which slows them down and spreads them out. Once the bomblets reach a force of 6 Gs they arm themselves. As the bomblets fall, they are also spinning. Arming takes about 2.6 seconds. They have a combined shaped charge, fragmentation and incendiary effect on the target. It is very effective against and mainly used for anti-personnel, anti-materiel, and anti-armor. Over two million of these sub-munitions were dropped over Kuwait and Iraq during the Gulf War. A 5% dud rate was expected, so around 100,000 unexploded bomblets remained after the war. Each was fitted with an extremely sensitive fuze and the US Army recommended that they not be moved.

Turbofan
The turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft engine, aircraft propulsion. The word "turbofan" is a portmanteau of "turbine" and "fan": the ''turbo'' portion refers to a gas turbine engine which achieves mechanical energy from combustion, and the ''fan'', a ducted fan that uses the mechanical energy from the gas turbine to force air rearwards. Thus, whereas all the air taken in by a turbojet passes through the combustion chamber and turbines, in a turbofan some of that air bypasses these components. A turbofan thus can be thought of as a turbojet being used to drive a ducted fan, with both of these contributing to the thrust. The ratio of the mass-flow of air bypassing the engine core to the mass-flow of air passing through the core is referred to as the bypass ratio. The engine produces thrust through a combination of these two portions working together; engines that use more Propelling nozzle, jet thrust relative to fan thrust are ...

Williams International
Williams International is an American manufacturer of small gas turbine engines based in Pontiac, Michigan, United States. It produces jet engines for cruise missiles and small jet aircraft. History Dr. Sam B. Williams worked at Chrysler on their automotive turbine systems, but always imagined a wider set of applications for the small gas turbine engine. He left Chrysler to form Williams Research Corporation in Birmingham, Michigan in 1954. In 1981, the company became Williams International. It has been building small turbofan engines since the 1950s for use in cruise missiles as well as target and reconnaissance drones. Using the missile engines, Williams developed a series of personal VTOL flying craft, including a jet-powered belt in 1969, the Williams Aerial Systems Platform (WASP), also known as the "flying pulpit" in the 1970s, and the X-Jet, which was evaluated by the United States Army in the 1980s.Kocivar, Ben.Turbofan-powered flying carpet ''Popular Science'', Sept ...
