In the global military, information investigation determines whether the war occupies a favorable position. At the beginning of the twentieth century, the invention of the aircraft greatly improved the human detection capability. At the beginning, it was a manned aircraft. Over time, The development direction of reconnaissance planes is toward high speed, super high altitude, stealth and other directions. However, these also bring certain security risks. In the case of high-altitude and high-speed, the safety of the aircraft is decreasing. But now human rights have made great progress, leading to many dangerous investigations that cannot be carried directly by people. You need a drone to scout. Under this condition, Northrop Grumman developed a high-altitude high-speed unmanned reconnaissance aircraft to provide investigation information for the US military. This is the famous "Global Hawk" unmanned reconnaissance aircraft.
UAVs, also known as aerial robots, drove rapidly in the mid-21st century, first when the United States used drones as targets in the Vietnam War. But the real first thing to use in actual combat is Israel. In the 1982 Lebanese War, the use of military drones for fire reconnaissance opened the era of drone detection. Later in the Gulf War, the United States and its allies began to use drones for investigative operations. In the Afghan war and the Iraq war, drones were widely used for reconnaissance and attacks. At present, he mainly plays the role of reconnaissance aircraft, electronic jammers, artillery target guides and drones. The drone also made a great contribution to the victory of the war, and also allowed the investigation to enter a new era.
Compared with other drones, the "Global Hawk" can be described as a giant in the drone, 13.5 meters long, 4.6 meters high, 35.4 meters wingspan, and the maximum takeoff weight of 11.6 tons. It is also the most advanced drone in the United States and the world. As part of the “High-altitude Advanced Conceptual Technology Verification†program, the aircraft first flew in 1998. The Global Hawk has a maximum speed of 740 kilometers per hour, a cruising speed of 635 kilometers per hour, a range of 26,000 kilometers, and a 42-hour battery life. It can take off from the United States and reach any location in the world for reconnaissance. In 2001, the US military put the "Global Hawk" into the military strikes against Afghanistan for the first time. It carried out 50 combat missions, provided more than 15,000 enemy target intelligence and reconnaissance images, and also indicated targets for the "predator" flying at low altitude. In the Iraq war, the US Air Force used two "Global Hawks" and carried out 15 combat missions to help the US military destroy 13 Iraqi ground-to-air missile companies, 50 ground-to-air missile launchers, and 70 ground-to-air missile carriers. 300 ground-to-air missile boxes and 300 tanks. The US "Global Hawk" can carry 7 tons of fuel, so much fuel, so that the "Global Hawk" can stay in a target for up to 42 hours, the average aircraft can not reach this level, convenient The enemy continues to monitor. The flight control system uses the US GPS global positioning system and inertial navigation system for positioning and remote command of the aircraft. The Global Hawk has the ability to continuously provide data and responses from day to night in the enemy-occupied area, and it can be activated as long as it is needed by the military. It can take off from the United States and reach any location in the world for reconnaissance. The aircraft is equipped with three kinds of reconnaissance equipment such as synthetic aperture radar, TV camera and infrared detector, as well as defensive electronic countermeasure equipment and digital communication equipment. The detection capability of the aircraft is quite powerful.
"Global Hawk" has all-weather combat capability and can work in a complex climate. The Global Hawk can continuously monitor moving targets through obstacles such as cloud and rain at an altitude of 20,000 meters. Its synthetic aperture radar and TV cameras can accurately identify the ground. The types of aircraft, missiles and vehicles can even clearly distinguish the gears of car tires. The biggest advantage of Global Hawk is that it can be connected with the existing joint deployment intelligent support system and global command and control system. The images can be directly and real-time transmitted to the commander for use in indicating targets, warnings, fast attacks and re-attacks. Battle assessment. The Global Hawk can also be used in different communication control systems for the Army, Navy and Air Force. Both broadband satellite communication and line-of-sight data transmission communication can be performed. In addition, the machine is equipped with a backup data link. The Global Hawk Flight Control System uses GPS Global Positioning System and Inertial Navigation System to automate the entire flight control process from takeoff to landing. This is also in line with the US military's global integration strategy! And this global command and control system connection is very worthy of China's reference!
