Which countries in the world have drone technology?

United States: \x0d\ The United States has always been at the advanced level in the world in the research and development of unmanned aerial vehicles. Models and types are the most countries in the world. At present, the world is mainly concerned about Lockheed? Martin's "Skunk Factory" has developed a new drone "Cormorant", which can be launched from a submarine. The plane has a total length of 5.8 meters, a wingspan of 4.86 meters and a take-off weight of slightly over 4 tons, including a payload of 453 kilograms. The air inlet of the machine is located in the nose and is triangular. At the same time, because the fuselage is made of titanium alloy, it has extremely high strength and can withstand the pressure equivalent to 50 meters of water depth. In order to increase the concealment of flight, the shape of the "Cormorant" UAV also adopts stealth design. Cormorant's maximum flying speed is expected to reach 880 km/h, cruising speed is 550 km/h, maximum flying altitude is 10.7km, operational radius is 926 km, and it can last for 3 hours. It can be equipped with short-range weapons and reconnaissance equipment, which is used by the US Navy's "Ohio" class nuclear submarines. \x0d "Cormorant" is an exploration direction of UAV tactical development in the United States. If the development of the cormorant goes smoothly, the US Navy can equip the cormorant drone around 20 10 at the earliest. \x0d\ At the same time, the US military is developing a new generation of high-altitude high-speed reconnaissance plane SR-72 "Black Swift". This new reconnaissance plane is the successor of the famous Sr-7 1 "Blackbird" high-altitude reconnaissance plane, but its flight speed is faster, and its maximum speed exceeds 5 times the speed of sound. In addition, Sr-72 also has stealth capability and long endurance, which can meet the needs of global reconnaissance. It will monitor the world together with U-2 high-altitude reconnaissance plane, Global Hawk strategic unmanned reconnaissance plane and reconnaissance satellite system, and it is also an important part of the US global rapid strike plan. With its perfect camera equipment, the high-altitude reconnaissance plane flies over the reconnaissance target and takes high-resolution ground pictures, which is of great military significance. Because the flying height of high-altitude reconnaissance plane exceeds the shooting height of most fighters and air defense missiles, and the flying speed exceeds the flying speed of missiles, it is rarely attacked. At present, only the United States has a dedicated high-altitude strategic reconnaissance plane in the world. \x0d\ Israel: \x0d\ The Israeli Air Force has been the first to use drones. For the first time, unmanned aerial vehicles (UAVs) played a decisive role in the war, which was the battle of Bekaa Valley in 1982. During the war, Israel used its own reconnaissance plane as bait to enter the Bekaa Valley to lure Syria's Sam -6 air defense missile to fire. At the same time, many parameters of Sam-6 missile radar are measured. According to these parameters, Syrian air defense positions were suppressed by radio, and the result was one-sided. The battle of Bekaa Valley can be said to be the first time to show the role played by drones in modern warfare. \x0d\ At present, the Israeli Air Force pays more attention to Heron)TP UAV (called "Etan" by the Air Force) developed by Israel Airlines. It is the largest unmanned aerial vehicle in the world. Its wingspan is the same as Boeing 737 produced by Boeing Company of the United States. Its fuselage length is 14m, its wingspan reaches 26m, it can fly continuously for more than 20 hours, and its battery life can exceed 30 hours. Equipped with satellite communication equipment, the operational radius exceeds 1000 km, and it can conduct aerial reconnaissance on Iran, the old enemy. Equipped with 1200 HP turboprop engine, the flying speed exceeds 370 km/h, and the turboprop engine has good high-altitude performance, which makes the flying height of Etan reach 13700 m. In 2008, "Aitan" has set a flying altitude record of 12 190 meters, and the final goal will reach 15240 meters. Its main purpose is surveillance and reconnaissance, and its payload is 1 ton. It can also carry other devices to perform different tasks. Therefore, the UAV has full potential to perform new tasks, which can effectively attack Iran's nuclear facilities, complete reconnaissance, destroy enemy communications, connect ground command and manned fighters, and at the same time, the UAV can carry missiles to accurately strike enemy targets. \x0d\ Russia: \x0d\ The development of Russian unmanned aerial vehicles began at 1930, and experienced three development stages, from strategic unmanned aerial vehicles to tactical unmanned aerial vehicles to campaign and tactical unmanned aerial vehicles, which accumulated experience and laid a foundation for the development of unmanned aerial vehicles. In the early 1990s, due to the lack of funds and other issues, the development of Russian UAVs began to enter a trough. At the same time, UAV technology in the United States, Israel and other countries has begun to surpass Russia. However, in recent years, the Russian military has continuously increased its investment in the research and development of drones. Relying on its solid industrial foundation and the technical strength of some well-known aircraft design bureaus in developing UAVs, the UAV industry has made great progress. \ x0d \ 201kloc-0/10. In October, a Russian newest Stork UAV crashed in the ongoing test. The Russian military had previously planned to develop a military "Yuri -E" UAV based on this aircraft, which was used to indicate targets for tactical missiles in the "iskander" campaign. The crash has forced the Russian military to postpone the equipment plan of the new drone. \x0d\ At present, Russian military mainly uses "Tu-14 1" and "Tu-143" UAVs. \ x0d \ "Tu- 14 1 \", also known as "Swift", is a new generation of unmanned reconnaissance aircraft mass-produced by Kharkov Aircraft Factory, which is used for aerial reconnaissance of various campaigns and tactics. Its flying speed is 1 100 km/h, its range is 1000 km, and its flying altitude is 50 ~ 6000 m. Although the most effective altitude for reconnaissance is 2000 m above sea level, the height peak of 4000 m does not hinder the exquisite swift (8 m long, takeoff weight/kloc-0). The main airborne equipment includes TV cameras, thermal cameras and radiation detectors. \x0d\ "Tu-143 "tactical reconnaissance plane, also known as" flying ". It is an unmanned aerial vehicle that can fly autonomously, which was developed by tupolev Design Bureau in the early 1970s. The aircraft has a range of 500 kilometers and a flying altitude of 15, including terrain avoidance maneuver. The flying altitude can be from 100 meters to 2000 meters. According to the different reconnaissance modes (photography, television photography and radio reconnaissance), "Tu-143" can be launched in several different ways, and the flight can be controlled according to pre-programmed procedures. If the task changes, it can also be remotely controlled by ground personnel. It can fly in any weather conditions, not only reconnaissance over the plains, but also perform tasks in mountainous areas. During the recovery process, the drone decelerates through a parachute and then lands through a retractable sled. "Tu-143" participated in the Syrian-Israeli armed conflict, but Israel did not find it and failed to shoot it down. \x0d\ Later, tupolev Design Bureau improved "Tu-143" UAV, and its successor "Tu -243" tactical unmanned reconnaissance aircraft system was used for aerial reconnaissance, reconnaissance of targets in advance and observation of shooting and bombing effects within the combat depth of 150km, which can ensure that UAV is in the defense zone of enemy air defense weapons and possible nuclear, chemical and bombing. It can effectively find important enemy targets, such as nuclear artillery companies, surface-to-surface missiles and air defense missiles, such as transportation hubs, positions, troop assembly sites and command posts of divisions and armies. The obtained and recorded reconnaissance information will be received, processed and decoded in time on the reconnaissance plane and on the ground, the target will be identified and its coordinates will be determined, photographic files will be made and information will be transmitted. \x0d\ At present, SukhoiS-62 strategic UAV is the main new UAV being developed in Russia. It is equivalent to the US Global Hawk strategic reconnaissance plane. Modular reconnaissance equipment is mainly used, which can be used for image acquisition, information reconnaissance and electronic jamming. After the aircraft is equipped with troops, it will greatly improve the strategic combat capability of the Russian army. \x0d\ UK: \ x0d \x0d\2009,110 in October, BAE Systems completed the first flight of the "Mantis" UAV in the technical verification plan invested by the British Ministry of Defence. This first flight successfully carried out a series of tests, which verified the capability of the UAV system and its potential to meet the future operational needs of Britain. In addition, this work has also enhanced the confidence of the UK to independently develop the hollow long-endurance UAV system. At present, Britain's "Mantis" and France's "Neurons" are the epitome of advanced aviation technology in Europe. \x0d\20 12 London Olympic Games, the RAF will use Reaper UAV to monitor the security in London. This type of UAV is equipped with infrared sensor, radar scanning device, electronic monitoring equipment and high-definition camera equipment. This drone will be used to monitor suspicious people and vehicles moving near the stadium. The speed of Reaper UAV can be increased to 400 km/h, and it can fly continuously at an altitude of15000m 14 hours. The Reaper UAV can carry four Hellfire AGM- 1 14L or AGM- 1 14K anti-tank missiles and two 250kg laser-guided bombs when performing combat missions. At present, the Royal Air Force has three Reaper drones, which are now deployed in Afghanistan to carry out combat missions.
