- The main propeller in tandem (1), consisting of two four screw-blade propellers
- vortex attenuation (2) to reduce turbulence of water flow after passing through the propeller.
- low speed auxiliary propellers (3). These two small electric propellers were also installed in the Alpha-class SSNs and served to move quietly at low speed (3/4 knots). The small diameter of these propellers would require a relatively high torque speed and they may not sound so silent.
- fine control surfaces on the main (4) rims
- the pod of the towed passive antenna "Ruza-P" (5)
