The driveline CODAG ship type and consists of two gas turbines "Proteus" power 3310 kW and by two diesel engines MTU 20V 538 TB92 after power 2648 kW. It has four drive axles. Diesel engines are the main drive and are used for navigation in normal conditions (regime cruises), while the gas turbine designed to achieve higher speeds required in the fight. With run only on diesel engines ship achieves a top speed of 25 knots, just with gas turbines 28 knots, while the maximum speed (CODAG) 40 knots.



According to the original project, the ship was supposed to carry the four French missile MM-38 Exocet, but the decision was changed, and then was elected as a new variant of the Russian missiles Stix SS-N-2B / C.
