According to the announcer the first Tu-160 was Tu-160M, but i don’t think it *really* was a modernized one. There were no Su-27SM iirc and there isn’t such a thing as Su-30M in RuAF 😛 Don’t think Su-30M2’s too part either. There were however MiG-31BM’s, Su-35S, Su-34, Su-30SM. Maybe some Su-25SM too, not that they are particularly new.
I reported on a good while back that T-50’s wouldn’t take part in parade.
You have better eyes than mine (or better place to see parade). 😉
