No , sanctions are in effect , more in the way as usual. If not anything else they are a major hick up.

 I think it is fair to say the performance of Russian Military Systems is as expected.

With a few exceptions the entirety of them is still counting on Soviet Thinking , Some of the systems seem promising but they have a logistics problem which can only be filled with Chinese support or India Co Op whatever which allows India to play the southern partner in this ac ward alliance.

I am not sure about Su 57 it can fulfill any role when it comes to Russian National Interests long term they will probably turn it to some export model more like an F 35 hussler.
