Unmanned aerial vehicles equipped with radars based on active electronically scanned array (AFAR) technology could significantly strengthen Russia’s protection against strikes on its territory. This approach to reinforcing air defense was proposed by military analyst and air defense historian Yuri Knutov.

According to him, such UAVs could operate at high altitudes and detect incoming threats — including cruise missiles and drones launched by an adversary — from long distances.

Knutov explained that drones carrying AFAR-based radar systems could effectively function as airborne early warning and control platforms. In this role, two or three of these UAVs could patrol along a designated line for up to a full day, maintaining surveillance from high altitude. Positioned roughly 150–200 kilometers from the former border between Russia and Ukraine, they would be capable of monitoring the airspace for cruise missiles and aircraft-type drones.

The analyst also noted that UAVs equipped with radar stations could transmit detection data directly to air defense command centers. This would allow incoming targets to be identified in advance and intercepted while still approaching. Interceptors, helicopters or surface-to-air missile systems could then be deployed to destroy the detected threats.

Knutov added that the most effective option would be radar systems based on AFAR technology with an analog-to-digital converter, which are capable of detecting virtually any moving object. He suggested that cooperation with China could be considered when acquiring such systems while domestic development continues.

The expert emphasized that such a solution is becoming increasingly relevant given the expected growth in the number of aircraft-type drones and cruise missiles available to the Armed Forces of Ukraine.

Meanwhile, on March 12 the Russian Ministry of Defense reported that over the previous day Russian air defense systems had destroyed 447 drones and six HIMARS rockets launched by Ukrainian forces. In addition, three guided aerial bombs were intercepted.
