Any truth to this, fellas?
By the time it is ready the USN is not going to be the problem it is now or has been in the past.
Having said that an aircraft carrier means mobile fire power that can move anywhere around the world in a relatively short time and can make sure Russian interests are not walked all over with no regard.
If Russia really intend on building that carrier we might seen rebuild of Baltic Shipyard or expansion of other shipyard. As well as a proper naval Su-57 prototype being tested at naval aviation base.
Actually the huge shipyards in the Far East are intended for making the big ships and Sukhoi has talked about a carrier based Su-57... and will probably start working on that now.
I would add it is amusing seeing a brand new carrier design with Yak-44 AWACS and Ka-27 helicopters. Minoga is more likely and possibly something developed from the Il-212 could be used as an AWACS platform.
but should the Checkmate see rapid success in its development as a land-based platform, then it might make better sense to develop that aircraft into a naval platform also, but fuel is always the deal-breaker when it comes to having a carrier-based fighter and we still need to see what kind of internal fuel capacity the Checkmate will have.
I don't think they would go for a single engined light fighter for carrier use. You are not going to have a lot of them so why not make them the best (Su-57).
They are building a new shipyard complex near St. Petersburg?
They have a lot of new ships they need to build before they start to build fixed wing carriers.
Remember in 2028 they will be launching two 40K ton helicopter carrier landing craft...
They are going to need escort ships, which means destroyers and probably cruiser sized ships for serious anti air capacity.
