You’re in a much better position than I, hence the question.
What about their S-300s? TOMBSTONE ain’t no joke although the IAF appears to be able to defeat it...better than the that IL-20 crew.
Modern Russian stuff is good, but they've also painted our a/c with their RF. I don't see our AF sitting around and ignoring the threat and a counter. -35 pilots walk around with a "Wild Weasel/ YGBSM" patch...I can't envision them without a means to defeat modern Russian SAMs.
I bust on the AF, but I refuse to believe it's threat model stops at SA-2's and/or SA-6's with radar guided AAA as a secondary layer. Syria isn't just about keeping Assad in power, the technical battle is immense and unheralded; Russian ELINT isn't half-assed.
