. “But ‘Krasukha-2’ is not altogether such universal equipment capable of jamming numerous radars as it is fashionable to believe. It cannot simultaneously jam both E-8 ‘AWACS’ and E-2 ‘Hawkeye,’ since a jamming station suppressing only the required band of very distinct frequencies for DRLO aircraft radars will be needed for each type of DRLO aircraft.”

“It’s notable that work on ‘Krasukha-2’ began back in 1996 and was completed only in 2011.”

“The ‘+30 dB’ idea is used in yet one more of the newest developments of VNII ‘Gradient’ — 1RL257 ‘Krasukha-4,’ which is at present being actively placed in EW brigades and independent battalions and is designated for suppression of air-based radars, including not only those on fighters and fighter-bombers, but also on E-8 and U-2 reconnaissance aircraft. True, there are doubts about the effectiveness of ‘Krasukha’ against the ASARS-2 radar at a U-2 altitude, since, judging by the available data, its signal is not only sufficiently complex, but still also noise-like.”

“In the opinion of developers and the military, under certain conditions, the 1RL257 can even jam warhead seekers of AIM-120 AMRAAM ‘air-to-air’ missiles, and also the command and control radars of the ‘Patriot’ surface-to-air missile system.”
