The Russian Army has been using the 1RL257 Krasukha-4 ground-based electronic warfare system at the Hmeymim airbase already for one year.
About a year ago, media reported that the Russian Armed Forces deployed the 1RL257 Krasukha-4 ground-based electronic warfare system at the Hmeymim airbase. During 12 months of the Russian operation in the Middle East, there were many different events, but all this time, the electronic warfare system served as a shield for Russian troops.
Reportedly, the Krasukha-4 is currently protecting the Hmeymim airbase from various spy planes, including US aircrafts, flying over the Mediterranean Sea. The Russian system is also preventing the work of reconnaissance satellites. If it is needed, it is also capable to suppress radars of sighting system of fighter jets.
The Krasukha-4 is mounted on a chassis of the KAMAZ-6350 four-axle heavy truck. The limit of the work in azimuth is 360 degrees; the limit of the work in angle of site is from -1 to +85 degrees.
The electronic warfare system has the following traffic handling capacity: one radar system of a satellite vehicle and one Northrop Grumman E-8 Joint Surveillance Target Attack Radar System (E-8 JSTARS) or eleven radar systems of tactical reconnaissance aircraft.
The radius of the zone of coverage during suppression of radar systems of tactical reconnaissance aircraft is 11-19 km, of target-acquisition and fire-control systems – 16-41 km, of satellite vehicles – 15-25 km. The deployment time is up to 20 minutes.
