How radar, missiles, helicopters, and mobile units work together to counter attacks designed to overwhelm the system
Moscow, October 6. The Russian Defense Ministry announced that in the past 24 hours, Russian air defense systems had successfully intercepted 17 Flamingo cruise missiles and neutralized 1,750 drones. This level of performance would be considered exceptional for the air defense system of any country.
Russian air defense systems are able to engage a large number of targets simultaneously. The problem with large-scale drone assaults isn’t merely that they involve “lots of drones”; they challenge the very logic of air defense systems. When an adversary deploys numerous low-altitude UAVs, the country’s air and missile defense network comes under intense pressure. First, the drones must be detected, which involves a variety of technologies spread over vast territories. Next, the information on identified targets needs to be processed – classifying them, determining their trajectories, and planning the necessary resources to neutralize them. Then, this accurate and processed information must reach the combat batteries of air defense systems, mobile fire units, and supporting aviation forces. Finally, the target can be eliminated. Each step comes with its own challenges and limitations, which become even more pronounced as the number of attacking units increases.
Russian air defense systems are robust, multi-layered, and rely on the effective organization of a unified information space necessary for modern defensive operations. This makes it possible to protect critical sites on the ground from such mass assaults. All stress tests have been successfully passed. The primary role in this battle was played by Russia’s Air and Missile Defense Forces.
Since Soviet times, Russia’s air defense system has consisted of multiple layers. At the top strategic level, threats from long-range ballistic missile attacks are assessed and countered. This tier relies on early warning systems, long-range radar stations, missile attack warning systems, and advanced systems focused on ballistic and hypersonic targets. Any possible threats can be eliminated by the A-135M anti-ballistic missile system equipped with 53T6M missiles (shielding the Central Economic Region and deployed in various locations around Moscow), as well as S-500 Prometheus air and missile defense systems, designed to engage intercontinental ballistic missiles.
S-400 Triumph systems form the backbone of regional air defense. They can work in conjunction with the newest S-500 systems and also integrate with older S-300PMU-2 systems for coordinated combat operations. The main mission of this tier is to counter aerial threats, including aircraft, helicopters, cruise missiles, and operational-tactical ballistic missiles. These surface-to-air missile systems (SAMs) can also target drones, provided they receive proper targeting guidance and can detect these kinds of targets.
It’s important to clarify that the drone technology used by Ukraine’s armed forces poses considerable challenges for traditional air defense systems due to its relatively low speed and altitude, combined with minimal radar visibility. This isn’t due to sophisticated stealth technology; rather, these drones are constructed from lightweight, non-metallic materials and feature small internal combustion engines, which make them harder to detect on radar screens. Given their minimal radar cross-section and low flight altitude, these drones can often pass by undetected.
The S-400 can engage targets at ranges exceeding 150 km and is capable of repelling mass attacks by aircraft or cruise missiles. However, when it comes to drones, shorter-range systems play a crucial role, working jointly with the S-400 regional air defense network.
Key players in the fight against drones include the following systems: S-350 Vityaz, Tor-M2, and the terminal defense system Pantsir-S1. These systems are ideal for countering large-scale drone assaults; they are the ones that fight the main battle against UAVs.
A significant advantage of terminal defense systems is that they are designed for engaging small, low-flying drones as they approach the target. Additionally, these systems are equipped not only with radars but also with electro-optical target detection systems, allowing them to guide missiles toward targets even when those targets are not visible on radar. Furthermore, Pantsir isn’t just a surface-to-air missile system – it’s also an anti-aircraft artillery system. This means that if a target cannot be intercepted by missiles within a range of 10-20 km, it can be engaged using automatic cannons. This makes it particularly effective against slow-moving drones.
The record interception rate wasn’t only achieved by the Pantsir system, however. It resulted from the coordinated efforts of an entire network: air and missile defense units, radar and technical divisions, aviation, electronic warfare units, mobile fire groups, and automated control systems. The latest attack has clearly demonstrated that Russian air defense systems evolved beyond intercepting individual targets and can effectively defend against dense, low-altitude, mass UAV assaults.
Mobile units and aviation step in
To deal with slower drones, new air defense structures – known as mobile fire groups (MFGs) – are being employed extensively. These agile units, equipped with machine guns and portable surface-to-air missile systems, can be deployed either along drone flight paths or near specific infrastructure. While the effectiveness of these units depends on being in the right place at the right time (since their engagement range is limited), they are highly maneuverable, and given the slow speed of drones, they can set up defensive positions if they have timely intelligence about the type and direction of an impending attack. In fact, one of the key developments of the fall of 2026 was the implementation of a unified information system for organizing air defense against drones across various Russian regions. Such a system could significantly enhance the efficiency of mobile air defense units; and apparently, it’s already being used.
Army aviation helicopters are another useful asset in combating drones. Their speed allows them to catch up with drones, while their armament enables them to destroy these threats using both artillery fire and guided missiles. A considerable portion of downed drones can likely be attributed to the effective operation of frontline helicopters.
Cruise missiles such as Ukraine’s Flamingo pose a different sort of challenge. They are more complex compared to standard drones: they move faster, pose greater risks, and navigate terrain more effectively. In this case, Airborne Early Warning and Control (AEW&C) aircraft like the A-50M become indispensable; they monitor the air situation against the backdrop of the Earth’s surface and can direct interceptor aircraft toward targets. Receiving target data from AEW&C allows fighter jets to engage cruise missiles before ground-based air defense systems can establish a solid lock, or in areas where deploying a SAM would be less advantageous. The coordinated work of AEW&C, fighter jets, and ground-based air defense systems is crucial for repelling mixed attacks involving both drones and cruise missiles, and is the key to success in defensive battles.
Challenges or opportunities?
When it comes to combating drones, challenges certainly exist. The primary concern is the economic aspect: a drone may cost tens of thousands of dollars, but a missile is much more expensive. If the enemy launches thousands of drones, the defending side needs cost-effective alternatives – such as bullets, fragmentation shells, small missiles, electronic warfare (EW) systems, interceptor drones, and mobile units. This opens up avenues for the evolution of air defense systems.
Interceptor drones could prove effective against slower drones since their production costs are at least comparable to those of basic drones. However, an interceptor drone without a warhead would be utterly ineffective against a larger, aircraft-type drone – it simply wouldn’t be able to bring it down. Therefore, in the future, we may see interceptor drones equipped with munitions and capable of high-speed flight.
Another promising direction is the development of rapid-fire artillery systems using programmable munitions, like the ZAK-30 Citadel. These systems can fire multiple rounds accurately and then quickly switch to a new target. Moreover, such automated air defense systems have the potential to effectively combat swarms of drones – if not now, then certainly in the near future.
Efforts are also underway to create compact and relatively simple guided missiles for air defense systems. Such new missiles were designed for the Pantsir system, and we may soon see small, mobile air defense units equipped with these missiles. This would significantly reduce the cost of downing a drone and enhance the effectiveness of mobile groups.
Laser systems for neutralizing drones hold particularly promising economic prospects. While the initial cost of a laser system is high, the price per shot is minimal. Like rapid-fire automated artillery, lasers can almost instantly switch between targets. This makes them highly useful for countering drone swarms.
Overall, Russian air defense systems are becoming more sophisticated and offer unique capabilities in fending off mass attacks. The performance metrics of these systems are among the best in the world – this has been proven in real battle conditions, no propaganda or exaggeration involved. And this is just the beginning; air defense systems are evolving and will undoubtedly become even more effective in the future.
