The Baltic fleet earlier said the Grad is armed with Kalibr-NK and Onyx missiles and began trials in the Baltic Sea.

The Buyan class, Russian designations Project 21630 Buyan and Project 21631 Buyan-M, are series of corvettes (small artillery and missile ships in Russian classification) developed by Zelenodolsk Design Bureau for the Russian Navy.

The ships are primarily designed for operations within littoral zones to protect Russia's vast coastal areas. Due to the small tonnage, they can operate even within shallow parts of oceans and seas and Russia's extensive inland waterway system. The export variant is known as Project 21632 Tornado.

Project 21631 corvettes are armed with Kalibr missiles (SS-N-27 Sizzler by NATO classification). They are fired by an eight-cell vertical 3S-14 launcher. Kalibr strikes with cruise missiles at sea (3M-54 missiles) and ground (3M-14 targets.

The corvettes are also armed with 100 mm artillery gun A-190 and small-caliber antiaircraft artillery gun Duet AK-630-2. They also carry Gibka 3M-47 launchers.

The ship is 75 meters long, the displacement is 949 tons and the speed is 23 knots. Cruising capacity is ten days and the navigation range is 2.5 thousand miles. The crew comprises 52 men.
