History Of Unmanned Combat Air Vehicles
The history of unmanned combat aerial vehicles (UCAVs) is closely tied to the general history of unmanned aerial vehicles (UAVs). While the technology dates back at least as far as the 1940s, common usage in live operations came in the 2000s. UCAVs have now become an important part of modern warfare, including in the Syrian civil war, the 2020 Nagorno-Karabakh war and during the 2022 Russian invasion of Ukraine. Early years In July 1849, during the siege of Venice, the Austrian forces used unmanned balloons to drop bombs on the city. The Hewitt-Sperry Automatic Airplane, which first flew in 1917, was a US-developed flying bomb. The project continued through to 1925. The RAE Larynx was a similar project in the UK that ran from 1925 to 1929. One of the earliest explorations of the concept of the combat drone was by Lee de Forest, an early inventor of radio devices, and U. A. Sanabria, a TV engineer. They presented their idea in an article in a 1940 publication of ''Popular Mechan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MIT Technology Review
''MIT Technology Review'' is a bimonthly magazine wholly owned by the Massachusetts Institute of Technology, and editorially independent of the university. It was founded in 1899 as ''The Technology Review'', and was re-launched without "The" in its name on April 23, 1998 under then publisher R. Bruce Journey. In September 2005, it was changed, under its then editor-in-chief and publisher, Jason Pontin, to a form resembling the historical magazine. Before the 1998 re-launch, the editor stated that "nothing will be left of the old magazine except the name." It was therefore necessary to distinguish between the modern and the historical ''Technology Review''. The historical magazine had been published by the MIT Alumni Association, was more closely aligned with the interests of MIT alumni, and had a more intellectual tone and much smaller public circulation. The magazine, billed from 1998 to 2005 as "MIT's Magazine of Innovation," and from 2005 onwards as simply "published by MIT", ...

Glide Bomb
A glide bomb or stand-off bomb is a standoff weapon with flight control surfaces to give it a flatter, gliding flight path than that of a conventional bomb without such surfaces. This allows it to be released at a distance from the target rather than right over it, allowing a successful attack without the aircraft needing to survive until reaching the target. World War II-era glide bombs like the German Fritz X and Henschel Hs 293 pioneered the use of remote control systems, allowing the controlling aircraft to direct the bomb to a pinpoint target as a pioneering form of precision-guided munition. Modern systems are generally self-guided or semi-automated, using GPS or laser designators to hit their target. The term " glide bombing" does not refer to the use of glide bombs, but a style of shallow-angle dive bombing. Early efforts German designs World War I In October 1914 Wilhelm von Siemens suggested what became known as the Siemens torpedo glider, a wire-guided flying ...

HOBOS
A hobo is a migrant worker in the United States. Hoboes, tramps and bums are generally regarded as related, but distinct: a hobo travels and is willing to work; a tramp travels, but avoids work if possible; and a bum neither travels nor works. Etymology The origin of the term is unknown. According to etymologist Anatoly Liberman, the only certain detail about its origin is the word was first noticed in American English circa 1890. The term has also been dated to 1889 in the Western—probably Northwestern—United States, and to 1888. Liberman points out that many folk etymologies fail to answer the question: "Why did the word become widely known in California (just there) by the early Nineties (just then)?" Author Todd DePastino notes that some have said that it derives from the term "hoe-boy", coming from the hoe they are using and meaning "farmhand", or a greeting such as "Ho, boy", but that he does not find these to be convincing explanations. Bill Bryson suggests in '' Mad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AGM-65 Maverick
The AGM-65 Maverick is an air-to-ground missile (AGM) designed for close air support. It is the most widely produced precision-guided missile in the Western world, and is effective against a wide range of tactical targets, including armor, air defenses, ships, ground transportation and fuel storage facilities. Development began in 1966 at Hughes Aircraft Company as the first missile to use an electronic contrast seeker. It entered service with the United States Air Force in August 1972. Since then, it has been exported to more than 30 countries and is certified on 25 aircraft. The Maverick served during the Vietnam, Yom Kippur, Iran–Iraq, and Persian Gulf Wars, along with other smaller conflicts, destroying enemy forces and installations with varying degrees of success. Since its introduction into service, numerous Maverick versions had been designed and produced using electro-optical, laser, and imaging infrared guidance systems. The AGM-65 has two types of warhead: one has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ryan Firebee
The Ryan Firebee is a series of target drones developed by the Ryan Aeronautical Company beginning in 1951. It was one of the first jet-propelled drones, and remains one of the most widely used target drones ever built. Development Ryan Firebee I Q-2/KDA-1 Firebee The Firebee I was the result of a 1948 U.S. Air Force request and contract to Ryan for a jet-powered gunnery target. The first flight of the XQ-2 Firebee prototype took place in early 1951. The drone featured swept flight surfaces and a circular nose inlet. The initial models had distinctive "arrowhead" shaped endplates on the tailplane. The Firebee could be air-launched from a specially modified launch aircraft (Douglas A-26 Invader was first to be used for this), or ground-launched with a single RATO booster. Following successful evaluation the target was ordered into production for the USAF as the Q-2A, powered by a Continental J69-T-19B turbojet engine with of thrust. The Air Force then obtained small number ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surface-to-air Missile
A surface-to-air missile (SAM), also known as a ground-to-air missile (GTAM) or surface-to-air guided weapon (SAGW), is a missile designed to be launched from the ground to destroy aircraft or other missiles. It is one type of anti-aircraft system; in modern armed forces, missiles have replaced most other forms of dedicated anti-aircraft weapons, with anti-aircraft guns pushed into specialized roles. The first attempt at SAM development took place during World War II, but no operational systems were introduced. Further development in the 1940s and 1950s led to operational systems being introduced by most major forces during the second half of the 1950s. Smaller systems, suitable for close-range work, evolved through the 1960s and 1970s, to modern systems that are man-portable. Shipborne systems followed the evolution of land-based models, starting with long-range weapons and steadily evolving toward smaller designs to provide a layered defence. This evolution of design increasin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-aircraft
Anti-aircraft warfare, counter-air or air defence forces is the battlespace response to aerial warfare, defined by NATO as "all measures designed to nullify or reduce the effectiveness of hostile air action".AAP-6 It includes surface based, subsurface ( submarine launched), and air-based weapon systems, associated sensor systems, command and control arrangements, and passive measures (e.g. barrage balloons). It may be used to protect naval, ground, and air forces in any location. However, for most countries, the main effort has tended to be homeland defence. NATO refers to airborne air defence as counter-air and naval air defence as anti-aircraft warfare. Missile defence is an extension of air defence, as are initiatives to adapt air defence to the task of intercepting any projectile in flight. In some countries, such as Britain and Germany during the Second World War, the Soviet Union, and modern NATO and the United States, ground-based air defence and air defence aircraft ...

US Air Force
The United States Air Force (USAF) is the air service branch of the United States Armed Forces, and is one of the eight uniformed services of the United States. Originally created on 1 August 1907, as a part of the United States Army Signal Corps, the USAF was established as a separate branch of the United States Armed Forces in 1947 with the enactment of the National Security Act of 1947. It is the second youngest branch of the United States Armed Forces and the fourth in order of precedence. The United States Air Force articulates its core missions as air supremacy, global integrated intelligence, surveillance and reconnaissance, rapid global mobility, global strike, and command and control. The United States Air Force is a military service branch organized within the Department of the Air Force, one of the three military departments of the Department of Defense. The Air Force through the Department of the Air Force is headed by the civilian Secretary of the Air Force, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
