A new attack missile craft will start sea trials with Russia's Caspian Flotilla in early July, the Southern Military District said Monday.
The Grad Sviyazhsk Project 21631 missile corvette is due to join the flotilla after completing all trials and state tests before the end of the year, the district said in a statement.
The corvette has a displacement of 949 tons and maximum speed of 25 knots. It is armed with Kalibr (SS-N-27) anti-ship missiles, 100-mm and 30-mm guns, as well as Igla-1M air defense missiles.
In addition to the Grad Sviyazhsk, the Caspian Flotilla will also take delivery of an Uglich missile corvette, a Grachonok-class high-speed patrol boat, several Serna-class landing craft, and three tugboats in the near future, the strategic command said in March.
