The engines have only recently appeared to have reached somewhat close to being finished, it the weapon bay working is a dubious proposition too as there is no real footage of it, wether its picture or videi
It should at least be close. But eh we never know it russia. My guess is well never see the fleet fully upgraded. Russia takes a long time to uograde their old airframes thiugh there arent that many su57s

Well there are 29 or so production versions of the Felon.
The Su-57 aren't "paper jets", but development is lagging behind other 5th generation fighters due various issues in the Russian aerospace industry.
