Please! Those old TU-95 Bears are nearly 60 years old, prop driven, and cruise at less than 400 mph. They have the radar signature as big as a battleship and were likely tracked by an F22 sitting on the ground at Elmendorf (Anchorage).
Tu-95 production resumed in the 80s and 90s. Cruise speed is roughly the same as that of a B-52H and RCS isn't a big factor when you're launching standoff weapons from long range.
