Don’t know how good the Iranian’s are, but the IAF is darn good at jamming and EW. They Syrian air defense network reportedly suffered something akin to an electronic coronary when the Israeli strike went in and destroyed their nuclear reactor. I dont’ think anybody really knows how they did it.
The USAF speaks a lot about “electronic attack” when speaking of the capabilities of the F-22 radar system. What that is I can only imagine. It’s a good bet that the Israelis have developed a similar capability with their heavily modified F-15’s and F-16I’s.
The radar (AESA) on the F-22 (and F-35 for that matter) can be used as a “death ray” to disrupt and disable electronics. Dunno what the range or required dwell time is, though. That might be what the are referring to by “electronic attack.”
I don’t know that this capability exists for F-15s and F-16s. I suppose it could be retro-fitted.
