Of course, every fly can be detected and tracked by radar. All it requires is to reduce the RCS threshold. Nothing in the world, not even a mosquito, can evade radar. Let alone F-22. This is simple physics. Theoretically, only a black hole can evade radar by absorbing all incoming electromagnetic radiation.
Ultraviolet is also light. Can you see it?
You can’t see it with your eyes, but your skin get burned by it. You can therefore surely sense it.
Simple physics. Energy can neither be created nor destroyed, only converted from one form into another, or generated from matter according to E = mc^2. Radio wave is light. Light can be reflected or absorbed. If absorbed, light converts into heat. F-22 may have less RCS than F-15, but not by much. F-22 reflects light pretty well. You can see it with your eyes because it reflects light into your eyes. You can see it. So can radar.
As for stealth. That’s marketing gimmick. Stealth has never been proven in the real world. Not once.
Catching F-22 and its emissions?
F-22 is visible on S-400 radar. If you can see it, so can radar.

thermobaric?
bombardment of Aleppo, cluster used
Why still limit the payload of Tu-22M to 12x250kg bombs or 6x500kg bombs since they are now flying from Iran?
A dozen bombs is enough to bomb a base. Why overkill?
Alleged RT footage of first raid from Iran.
According to Reuters, not only Tupolev it seems.

Now I see Su-30 there and not any increase of payload dropped , so I have a doubt about the real relation between the video and the news.
What’s the escort fighter?
What? How can Tu-22M3’s refuel mid-air? I thought this capability only existed on some M2 variants before being removed due to SALT talks at the time. Have they modified the backfires?

seems the drone was small tactical one. but how can radar track so small drones. it supposed to be stealth size.

I didn’t even know Russia is operating in that part of Syria.
