During the Russian drills in late August 2017, the Krasukha-4 system “blinded” the navigation systems and made the precision weapons of the Su-34 fighter-bomber
Krasukha-4 is one of the most famous Russian electronic warfare systems. This is a mobile, ground-based, broadband multifunctional jamming station. The Krasukha’s primary targets are airborne radio-electronics (such as UAVs) and airborne systems guided by radar.
The history of the Krasukha project goes back to the 1990s. Government contracts for Krasukha-4 and Krasuhka-2 were awarded on July 25, 1994, and December 1, 1997, but they weren’t declared ready for mass manufacture until early 2011.
Krasukha-4 has been in service with the Russian Army since 2014.
Krasukha-4 is a modernized variant of the Krasuha-2 electronic warfare system, a mobile electronic warfare system to suppress spy satellites, ground-based radars and AWACS airborne systems. In case of need, it can interfere with the enemy’s combat system. The system has a range of up to 300 km.
The large range allows Krasukha-4 to suppress the activity of the low Earth orbit satellites and can cause permanent damage to targeted radio-electronic devices. Ground based radars are also a viable target for the Krasukha-4.
Krasukha jammers were reportedly deployed to support Russian forces in Syria. They have reportedly been blocking small U.S. surveillance drones from receiving GPS satellite signals.
In July 2018, an OSCE monitoring mission drone recorded a 1L269 Krasukha-2 among other electronic warfare equipment deployed near Chornukhyne, Ukraine.
Reportedly, Krasukha is operating around the Russian military base at Gyumri in Armenia to counter the use by Azerbaijan of Turkish-made Bayraktar armed drones as well as Israel-made Harop loitering munition.
According to the Armenian Defense Ministry official, the system destroyed 9 unmanned aircraft in just a week.
In the future, the Krasukha-4 system could even impact targets at extremely high altitudes, even those in outer space. This system will be able to jam the enemy spy satellite and create a dead zone around the active area, making it impossible for the enemy to track the area with satellites.
