How do you know they are worn out and old?
The Tup plant was cranking them out well into the ‘90s.
Our youngest BUFF is 40-something.
This is a snip from FAS.org

Russian Tu-95 and TU-95MS aircraft are now deployed at two air bases A total of nineteen TU-95MS16 and two TU-MS6, operating in the 121st heavy bomber air regiment, which forms part of the 22nd Air Division that is headquarteed in Engels Air Base in the Moscow region. At the Ukrainka airbase (73th Heavy Bomber Air Division) at Svobodny, there are 16 TU-95MS16 and 26 TU-95MS6 bombers that were redeployed from the Dolon airbase at Semipalatinsk in Kazakhstan. The TU-95K-22 bombers are subject to decommisioning. In early 1997 five TU-95K-22 were decommissioned and re-equipped in Zngyelse, and five at the Ryazan training center. Eight TU-95 are located at the flight-test institute in at Zhukovskiy [Ramenskoye], and one TU-95K aircraft serves as a static display in Ryazan.
The parts plants may still be cranking.
