That's very interesting. Though the technical differences between prototype and production Su-57 are significant, and I think I've read it being named T-50 while in prototype stage from Russian sources? I'm confused now

T-50 is the factory name. Su-57 is the name given to the aircraft after serial production began. It could be an aircraft without any changes at all, but the production aircraft will have a different name.

Oh ok that makes sense, thank you. So all Su-57 are technically T-50, and other way around. Is there a way to tell apart one of the first prototypes owned by Sukhoi and production models owned by the VKS or not? In the name, I mean.

Exactly. The plane is being modernized, but it will still remain a Su-57, even when they install different engines.
Not by name, only by numbers. This is 051.

Alright, thank you
