The Gremyashchy class (Russian: гремящий – "thunderous") is an advanced development of the Steregushchy-class corvette of the Russian Navy.[2] This follow-on project was designed by the Almaz Central Marine Design bureau in Saint Petersburg. The first ship was laid down on 26 March 2011[3] and the official ceremony took place on 2 February 2012.[4]

Programme

The ships of the Gremyashchy class are very large multipurpose corvettes, designed to complement the Steregushchy-class ships already commissioned or being built for the Russian Navy. They have been designed to have an improved habitability for higher endurance missions, and are able to launch cruise missiles.

The Gremyashchy-class corvettes were designed with German MTU diesels for propulsion.[5] Because of sanctions arising from the Ukrainian conflict, deliveries of MTU diesels beyond the first two units were stopped, resulting in the cancellation of further units. Instead, new units of the preceding Steregushchy-class corvette are being ordered.

Project 20385 are now being replaced with two new Russian-made 1DDA-12000 diesel turbines from Kolomna Plant at Severnaya Verf in St Petersburg, on 19 May, 2016. [6] Thus German MTU diesels are no longer required.

Design

The Gremyashchy-class corvettes differ from their predecessors of the Steregushchy class by greater dimensions and displacement. They have a steel hull and composite superstructure, with a bulbous bow and nine watertight subdivisions. Compared with the Soobrazitelny, Boiky, Sovershenny and Stoiky ships, which are fitted with Redut air defense VLS system of 12 launchers on the bow, these new ships are equipped with a UKSK VLS system comprising 8 launchers for SS-N-27 or SS-N-26 cruise missiles instead. The Redut VLS system with 16 launchers has been replaced on the stern. Another difference is the lack of the aft mast above the helicopter hangar, and single integrated mainmast that no longer includes separate open shelves for artillery and navigation radars.
