If you take away the 35s dubious at best stealth, it has zero chance against any variant of F-15. That’s just a simple factoid.
Basically if a 35 missile truck in non-stealth “beast mode” gets caught by a Sukhoi, it’s toast. If the same happens to a 15, the Sukhoi isn’t going home that day.
The pilots disagree - but you are welcome to your opinion.
