Russian weapons are capable of intercepting the full range of cruise missiles, including the American Tomahawk. Military experts have described the army's capabilities in combating such targets.
MiG-31s See Far
Military expert Dmitry Kornev noted that aviation will play an important role. The MiG-31 was created, in part, to intercept low-flying Tomahawks.
The MiG-31 has a fairly long flight range, and they see targets against the background of the earth's surface.
Satellites Enter the Game
Military expert Evgeny Damantsev explained that subsonic combat units can be detected at launch by Resurs-P optical-electronic monitoring satellites or Kanopus-V-IK satellites with IR sensors.
Then they can be tracked by 29B6 Container over-the-horizon radar stations (OTH radar) with an approximate route determination accurate to within a few kilometers.
AWACS A-50U
According to this data, an A-50U airborne early warning and control (AEW&C) aircraft will take to the air and preemptively engage the Tomahawks using the Shmel-M radar at a distance of 170 - 130 km against the ground.
Then the target designation will be sent to the automated control systems of mixed anti-aircraft missile brigades Polyana-D4M1 with target distribution between the batteries of the S-400, S-300V4, S-350A Vityaz and Buk-M3/M3A SAM systems.
Buk-M3/M3A is capable of simultaneously intercepting up to 36 targets in an above-the-horizon mode. Complexes with 9S36 radars on universal towers, equally spaced in missile-hazardous directions, will be able to work on Tomahawks even in a low-altitude mode of 50 - 30 m without "blind" zones.
In addition, a squadron of 12 Su-35S fighters is capable of intercepting 80 - 100 Tomahawks, especially since the speed of the latter does not exceed 950 km/h, and the effective reflecting surface reaches 0.1 - 0.15 sq. m.
