The 1RL257 or Krasukha-4 is a Russian-made mobile electronic warfare system designed and manufactured by the Company Bryansk Electromechanical Plant (KRET).
The Krasukha-4 is intended to neutralize Low-Earth Orbit (LEO) spy satellites, ground-based radars and airborne radars (AWACS) at ranges between 150 to 300 kilometers. The system is also able to cause damage to the enemy's EW (Electronic Warfare) systems and communications.
The Krasukha-4 has been described as a tool against “flying radars,” such as the USAF E-8 Joint STARS aircraft, or reconnaissance satellites - like the United States’ Lacrosse satellite - and a means of protection against surveillance and combat unmanned aerial vehicles, otherwise known as drones.
Equipment:
A large turret is mounted at the top of a shelter mounted at the rear of an 8x8military truck chassis. Two circular antenna are mounted on each side of the turret. A telescopic mast with another antenna is fitted at the rear of the turret. In travel position, the turret is stored inside the shelter. In combat position, two hydraulic stabilizers are lowered on the ground mounted on each side of the shelter.
Design:
The 1RL257 Krasukha-4 vehicle is fitted with a crew cabin at the front and one shelter mounted at the rear of the truck chassis. The cab can be fitted with a class 5a armour which provides a protection against firing of small arms AKM 7.62mm.
Mobility:
The 1RL257 Krasukha-4 is based on a Kamaz 6350 8x8 military truck chassis. The truck is motorized with the KamAZ-740.50-360 diesel engine developing 360hp. The truck can run at maximum speed of 95 km/h with a maximum road range of 1,000 km. the truck design ensures the fording depth of 1.75m.
Combat use:
Mobile electronic warfare systems Krasukha-4 suppress spy satellites, ground-based radars and airborne systems AWACS (Airborne Warning and Control System). The Krasukha-4 system works by creating powerful jamming at the fundamental radar frequencies and other radio-emitting sources. Krasukha-4 is able to effectively shield objects on the ground against radio-locating surveillance satellites, ground-based radars, or aircraft-installed Airborne Warning and Control Systems (AWACS)
