The Syrain's are starting to ask serious questions about how the IAF is bombing them at will and their vaunted Russian S-300 and 400 systems have ended up being pretty useless. https://breakingdefense.com/2020/06...-strikes-against-syria-raise-s-400-questions/ They are even criticizing them officially, unheard of in the past. https://syriadirect.org/news/how-does-israel-keep-getting-past-syria’s-air-defenses/ Meanwhile the Turks have placed future orders of S-400's on hold and havn't yet deployed the one they have because suddenly trading F-35s for S-400s doesn't sound like a very good deal. Especially since the F-35s are being retro'ed with the newer AGM-88E missiles that have advanced seekers including a MM wave one which means even if you turn the radar off the missile will seek on its own the radar return of the AAA unit, and in all kinds of weather. In other words it doesnt matter if you turn the radar off. Currently they have a range of 90 miles and the ER version will be at least 150 miles and the missile itself can be reprogrammed in flight to act as a standard strike missile should you change your mind about radars as a target. The F-35 can be detected, in the best conditions, about 20 to 30 miles from the S-400. Maybe closer if flying NOE. So the lightening can get within glide bomb range without being detected, a SDB-ll has a range of 40 miles depending. And a system detecting of a stealth aircraft is not the same thing as a missile lock, not that it matters cause the ground radar unit will probably have a short unhappy life. Anyhoo the IAF isn't even finding it necessary to take out the radars to complete their missions. And the Turks are starting to wonder why they made this lousy deal in the first place.
