Recently, NATO has received the fourth “Global Hawk” (RQ-4) UAV ordered from Norge company and stationed at siganella Air Force Base in Italy. In half a month, two “Global Hawk” UAVs have been stationed at siganella air force base, and NATO plans to put all five existing UAVs into operation in 2022. What kind of signal is behind these events? What is the impact on future intelligent warfare?
RQ-4 UAV has highly intelligent autonomous system and super long endurance, and excellent flight performance. RQ-4 fuselage length is 13.4 meters, height is 4.62 meters, wing span is 35.4 meters, maximum flight speed is 644 km / h, maximum flight height is 19810 meters, and maximum take-off weight is 11610 kg. RQ-4 airborne fuel more than 7000 kg, range up to 25000 km, autonomous flight time as long as 36 hours, can complete the transcontinental flight, can stay at 18300 meters above the target area for 24 hours of reconnaissance, so it can take off from the United States to any place in the world for reconnaissance. Traditional UAV system is guided by “human command”, while RQ-4 has highly intelligent autonomous system. Guided by “event response” and guided by inertial guidance and global positioning system (GPS), it can automatically complete the whole flight process from takeoff to landing, and automatically send the flight status data of UAV to the ground through satellite link Surface task control unit. The powerful endurance and highly intelligent autonomous system make RQ-4 have excellent flight performance.
RQ-4 UAV has advanced airborne reconnaissance equipment and data transmission system, and has strong intelligence, surveillance and reconnaissance capabilities. It is equipped with an integrated sensing module built by Raytheon company, including an integrated module with the functions of synthetic aperture radar, photoelectric and infrared sensors. Both photoelectric sensors and infrared sensors can be used with SAR at the same time. They have wide area and high resolution mode switching. They have ground moving target tracking mode. They can obtain banner reconnaissance photos with an accuracy of one meter, and fixed-point reconnaissance photos can even be accurate to 0.3 meters. Through its advanced data transmission system, it can carry out both satellite communication and line of sight data transmission communication, with a maximum bandwidth of 50 Mbit / s. And it can be connected with the existing “joint deployable intelligent support system” and “global command and control system”. The images can be directly and real-time transmitted to commanders for use, which can be used to indicate targets, early warning, rapid attack, combat evaluation and re attack.
RQ-4 UAV has excellent comprehensive performance and has a broad application prospect in unmanned combat of intelligent war. In the future intelligent war, unmanned warfare will become a new style of war, and unmanned combat platform is the development direction of weapons and equipment in the future. RQ-4 UAV has a highly intelligent autonomous system, and integrates intelligence, surveillance and reconnaissance. After combining with the intelligence processing, utilization and distribution system of the U.S. Army, RQ-4 can provide near real-time intelligence data for each theater and service of the United States, and master the battlefield initiative, so as to improve the overall effectiveness of the operation.
RQ-4A is the UAV with the longest flight time, the longest distance and the highest altitude in the world, and has maintained many of the highest records in the field of UAV in the world. However, “rq4” has low payload capacity and limited self-protection capability. Once locked by enemy fighters in the air, it is difficult to escape the fate of being shot down.
the “rq4” jet engine will produce certain infrared radiation signals when it works, so it is difficult to escape the pursuit of high-speed fighters. This puts forward new requirements for its sensor and stealth. Since the “rq4” was shot down, the US side has been striving to enhance its advanced sensor payload technology. After long-term development, “rq4” can be controlled by a laptop computer, and the ideal state is that each ground station can control four “Global Hawks” flying. “Rq4” also has an open architecture, which means that the software of the UAV is easy to upgrade, laying the foundation for dealing with the changes of the battlefield in the future.
at present, the U.S. military has upgraded the drone swarm operation to the strategic level, and “rq4” has once again become the focus of its cluster operation concept. The United States plans to realize UAV bee colony operation in 2030, and take the bee colony unmanned combat as an important mode to seize the air control and information control power in the future. The core of realizing “bee colony technology” is to achieve accurate and rapid information transmission and intelligent and independent decision-making of the system. The US military side said that relying on its advanced intelligent integrated chip technology and the decentralized use of a large number of low-cost unmanned platforms, it can achieve the occupation and control of the vast battle area.
in recent years, the U.S. side has been actively engaged in diversified modification and upgrading of “rq4”; the model 396 of the US Air Force’s special beheading operation is the small rq4; the US Air Force intends to use tens of thousands of small UAVs to break through the integrated air defense systems of other countries. In addition, rq-4b maintains the requirements of endurance and range, and greatly improves its payload capacity by extending the fuselage wing. In terms of attack and damage, the new-type “rq4” UAV carries a “suicide” system, which can automatically identify the approaching target and achieve the strike effect by self exploding. The reaction time of the enemy is short and the protection is difficult.
in terms of intelligent attack and defense, unmanned operations and anti unmanned operations will become the focus of war. While using “rq4” for unmanned combat, the United States is vigorously developing anti unmanned combat system. After the realization of unmanned combat platform, the “three non” operational guidance proposed by the US Army will inevitably lead to the aggravation of war asymmetry, and the requirement of anti unmanned combat is unprecedented urgent. With the rapid development of new technologies such as artificial intelligence and big data, unmanned combat style is born, which indicates the arrival of intelligent war. According to the U.S. military, the United States has established a special leading organization for unmanned combat and anti unmanned combat to guide the research and development and operational application of U.S. military equipment.
with the rapid development of computer operation and storage, the great progress of pattern recognition and adaptive reasoning, “rq4” is becoming more and more intelligent, and the human-computer interaction control mode will further develop to full autonomous control. With the maturity of fully autonomous control technology, “unmanned platform, manned system” will be more perfect. Through the intelligent integration of man and machine, UAV will have a strong “learning” ability. Under the command of the command, it can better adapt to the complex battlefield environment and complete the combat tasks independently, which undoubtedly poses a great challenge to the existing joint operation concept and integrated operation style.
