The POWER of Russia's Murmansk-BN electronic warfare complex
Murmansk-BN can have an impact on military objects within a radius of up to 5,000 km. With good radio transmission, the range of the system can be increased to 8,000 km.
Murmansk-BN automatically scans over a large area. If sources of radio emissions are detected, the system's transmitters start jamming in narrow bands, so that the enemy can't exchange information.
