Mission

The Project 1239 Sivuch guided missile air cushion ship is designed to destroy enemy surface ships, fast attack craft, and transports in all water areas of closed sea theatres of operation and in short-range zone of open seas, when operating autonomously or as a flagship of uniform/mixed naval groups.

Features

Thanks to its well-balanced sensor/armament mix and high navigability, Sivuch is capable of efficiently detecting and engaging surface and air targets with missiles and artillery fire at their maximum effective range without limitations in high sea (sea point up to 5 inclusive) and adverse ECM conditions.

The onboard active and passive ECM assets efficiently protect the ship from enemy missile systems targeting.

The ship can be deployed in any battle group due to a wide range of speeds provided by transformable hydrodynamic platform and main machinery.

The ship’s high reliability and maintainability, catamaran hull made of corrosionresistant aluminum-magnesium alloys, skirt, and flank-speed propulsion plants have been proven in long-term operations.

Main propulsion plant

Air cushion ship is powered by a combined CODOG-CODAG diesel/gas turbine plant comprising two M511A reduction gear diesel units, two M10D1 flank speed gas turbines, and two M527OM3 auxiliary diesel motors to drive superchargers inflating the skirt.

The onboard electric power system incorporates four 200 kW diesel generators and four 1EKPV 15/150 electric compressors.
