How did it get the name "Checkmate" for such a new fighter? This doesn't sound like a NATO assigned code name which should have its name starting with "F". Did Sukhoi come up with that on its own?
One senior Sukhoi exec explained it (apparently!) as given the name Checkmate because the Su-57 is akin to a queen on a chessboard, the most capable and "valuable" piece (only in terms of strategic hardware lol) but not to be used so lightly and isn't as numerous as another like the knight. That's also why they used the knight in the promo.
Checkmate I'm guessing is in reference to capturing a market and providing a sound counter to fighter development in the US, China, Korea, and Europe. As in it is capable of ending this game because it is capable of doing xyz for under a certain cost.
2023 first flight and 2025 finishing up testing? I imagine around 2030 intro into airforce/s.
You know well that NATO codename will begin with "F". Checkmate is marketing name for now and probably not even program name given by Sukhoi or Russians.
Looks to be heavily export oriented. VKS going in would be a coin flip for now.
