“Russia has a “heavy lift capability”. At one time, and maybe they still do, have the largest air cargo transport plane in the world.”
Actually, I think they built two of them. Not sure if they’re both flyable anymore though.
They only made one and a second was under construction but cancelled. The one they did build is not only still flyable but in regular use. They just upgraded the avionics and it’s in revenue service again.

However, the Chinese have decided to fund the completion of the second one and potentially produce more for themselves.
