Tu-95 Bear propeller velocity
I was watching a documentary on the mighty Tu-95 and it was mentioned that the propeller speed at the tips are supersonic.

Is this correct? I have heard propeller and rotor tips go briefly supersonic; for example on T-6 Harvards. However I always believed that this was highly inefficient and one of the factors limiting the top speed of propeller aircraft.

Please enlighten me...
