In recent years, with the large-scale deployment of drones on the battlefield and significant achievements, how to counter them has become a research and development focus for various countries. Many countries have chosen to use drones as a countermeasure against them. Under the combined influence of various factors, interception drones have received attention from countries and entered a period of rapid development. Recently, according to foreign media reports, Belgium is deploying two types of drones, one of which is the Blaze interception drone produced in Latvia. A Czech company also showcased its EAGLE-ONE drone, which can capture targets using a portable "flying net" drone. The London based defense research and development company has announced its development of the "Xiaoxun Raptors" interception drone, which is said to be capable of handling drones with speeds exceeding 250 kilometers per hour. So, why are interception drones attracting attention from various countries? How do they implement interception? What is the future development trend? Please refer to the interpretation in this issue. With unique advantages, from the Nagorno Karabakh conflict to the Russia-Ukraine conflict, UAVs are changing the combat style in an unprecedented way on the battlefield. Especially the cluster use of drones brings great pressure to traditional air defense systems. Faced with the increasingly severe threat of drones, countries have adopted various anti drone measures, mainly divided into hard destruction and soft killing. However, traditional countermeasures, regardless of which one is mentioned above, have certain limitations. One is a serious imbalance between cost and benefit. Traditional hard destruction methods such as anti-aircraft guns and short-range air defense missiles are still cost-effective for dealing with high-performance drones. However, when dealing with low speed and small drones, there are not only difficulties in detection and tracking, but also low cost-effectiveness. Secondly, the technical performance cannot keep up with the constantly changing battlefield. An obvious example is electronic interference. With the deployment of fiber optic drones in combat, traditional radio interference methods are almost ineffective because they do not radiate signals externally. Thirdly, there is insufficient flexibility. One major challenge in intercepting drones is their unpredictable movements, making it difficult to determine their direction and path of attack. Traditional interception methods are often based on larger platforms, which determines that they lack sufficient flexibility in deployment. Traditional countermeasures are either "unaffordable," "slow to respond," or "ineffective," so countries are beginning to seek low-cost interception methods that are viable. Intercepting unmanned aerial vehicles have emerged in this context. The concept of interception type unmanned aerial vehicles can be traced back to the Cold War era. In the 1960s, the US Navy developed and deployed the QH-50 unmanned helicopter. Although its main mission was to launch torpedoes against submarines, its appearance proved the feasibility of remote air systems carrying and using weapons, which inspired the idea of using unmanned platforms to carry out interception missions. However, limited by the technological level at that time, the development of air-to-air interception drones was still in the conceptual and conceptual stage. In the 21st century, Israeli companies were the first to put the concept of "intercepting drones with drones" into practice and launched the "drone dome" system. On the Syrian battlefield, the Russian military has also begun using "outpost" drones equipped with specialized equipment to interfere with enemy drones. Compared with traditional countermeasures, interception drones have multiple advantages. One is the concealment of actions. Intercepting drones are usually small in size, while some larger drones of this type use wing layouts to reduce the radar reflection cross-sectional area, so the signal characteristics are not obvious and difficult to detect, which can improve the success rate when countering target drones. Secondly, the cost is relatively low. The interception type unmanned aerial vehicle adopts various methods to reduce costs while ensuring performance, such as using composite materials to manufacture the fuselage and using shelving products for internal components. Some drones equipped with sensing devices are also striving to reduce manufacturing and usage costs to ensure large-scale use. The third is flexible deployment. Most interception drones have the characteristics of portability and ease of use, especially some newly developed interception drones designed to be carried by teams or even individuals, allowing users to quickly respond to current threats. The fourth is low collateral damage. Intercepting drones can generally achieve a certain level of attack accuracy by carrying perception devices and integrating artificial intelligence, resulting in lower collateral damage. There are various interception methods, and to some extent, drones have become a true "airborne spear" on the battlefield of armed conflicts in some hotspot areas. Correspondingly, interception type drones are referred to as the "Sky New Shield" against drones. It should be pointed out that interception drones are a general term, and in some countries, they are also referred to as drone interceptors. Regardless of its name, it cannot be denied that the interception methods used by current interception drones are still increasing. From the development of interception drones in various countries, according to their destructive mechanisms, these drones can be mainly divided into categories such as physical collision, net throwing capture, electronic suppression, and carrying warheads. Physical collision type unmanned aerial vehicle. These types of drones have fast speeds and rely on their sturdy bodies and high kinetic energy to collide with targets. The Russian "Dagger" drone, with a speed of 300 kilometers per hour, is equipped with an infrared seeker that can detect the infrared thermal signals of enemy drones and destroy targets through high-speed impact. Ukraine is also equipped with such drones, such as the Stinger drone. As heavy drones are deployed on the battlefield and play an increasingly important role, some countries have begun to develop specialized physical collision drones specifically designed to deal with these heavy targets. The Gobi high-speed drone developed by a French company belongs to this type. Throw net capture drone. Many drones use propeller propulsion. Therefore, some interception type drones aim at the "seven inch" of the drone by launching capture nets or using ropes to wrap around the target rotor, causing it to lose power. If the US military's "coyote" intercepts drones, it can launch capture nets to deal with rotary wing drones. Electronic suppression drone. Some interception drones use electronic jamming devices to implement close range electronic suppression on target drones, causing them to lose control. For example, Block III of the American "Coyote" and FPV drones equipped with radio frequency interference modules in some countries use this interception method. When approaching the target, they will emit directional electromagnetic pulses or continuous interference signals to cut off the control link of the target drone. Carrying a warhead style drone. Some of these warheads are fixed on drones and used as FPV drones, such as the Blaze interception drone produced in Latvia, which is equipped with airburst warheads. Some are used as modular replaceable payloads to intercept targets by launching ammunition from drones. The US CobraJet interception drone can carry multiple Viper rockets, and with the assistance of photoelectric sensors and visual recognition artificial intelligence, it can detect, identify, and intercept target drones. In actual combat, some countries have also chosen the approach of "drones+shotguns/portable air defense missiles" to enable this combination of equipment to play the role of intercepting drones. In addition, with the continuous miniaturization and lightweighting of some directed energy weapon systems, some newly developed interception drones have begun to "test the waters" of carrying directed energy weapons, but such interception drones are currently in the experimental stage. With the application of artificial intelligence, cluster technology, and new materials, the development of interception drones is flourishing, and its future evolution will revolve around the following aspects. The reaction speed is faster. With the emergence of jet powered drones, interception drones must have a faster response speed in order to "strike fast". Faster response speed comes from the development and application of new engines such as small turbojet engines and even scramjet engines; On the other hand, it comes from the improvement of the performance of unmanned aerial vehicles' onboard weapons. Becoming smarter. With the increasing complexity and variability of drone flight paths and attack methods, future interception drones can only rely on artificial intelligence to become more "autonomous" and achieve "adaptability" to ensure interception effectiveness. A Czech company has introduced advanced AI for EAGLE-ONE drones, while Ukraine has equipped its frontline deployed Leleka-100 reconnaissance drone with an anti interception system, confirming this development trend from both positive and negative perspectives. Emphasize the ability of cluster collaboration. The rapid development of bee colony technology has made it possible for drones to launch coordinated attacks. Correspondingly, interception type drones can only effectively respond by focusing on the following two aspects. One is to continue to decentralize the use of interception drones, so that combat teams and even individual soldiers can carry corresponding interception drones. The second is to strengthen the self-organizing network capability of interception type drones, using AI to create an interception type drone network that can compete with drone swarms, in order to efficiently respond to high-value targets and cluster targets. Further integration into the combat system. In the future battlefield, the confrontation between drones and anti drone systems will become more intense. Intercepting drones, as the "new shield of the sky", will inevitably receive increasing attention from countries around the world. Especially with the accelerated improvement of capabilities, it is highly likely that it will be deeply integrated into the combat system in the future. With the assistance of radar, satellites, and other means, it will be combined with traditional air defense firepower, directed energy weapons, electronic interference, manned fighter interception, and other methods to jointly build a higher-level defense system.
