Gremyashchy-class corvette

The Gremyashchy class (гремящий – "thunderous") is an advanced development of the Steregushchy class corvette of the Russian Navy. 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 and the official ceremony took place on 2 February 2012.

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.

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 chopper hangar, and single integrated mainmast that no more includes separate open shelves for artillery and navigation radars.
