This site provides more than 50 images of Soviet/Russian submarine propellers from
the WHISKEY through the YASEN including:

The VICTOR III that tore the towed array from the USS McCloy in drydock in Cuba with
the array still enmeshed in the tandem prop.

The LOSHARIK with a 4-bladed (not 3) propeller that can be thrust vectored.

The LADA with a skewed 7 and retractable thrusters.

The SIERRA with a 6B prop.

Take your time and be sure to read the captions, especially for the images of the
tandem propellers which include the wreck of the MIKE at a depth of 5528-feet.

Incredible says it all! Thanks for sharing. Jack
