Description: The Project 21630 Buyan, Project 21632 Tornado export version, is a new generation of river-sea type gunboat designed to protect Russia's 200-mile maritime economic zone and provide naval gunfire support for counterterrorist operations. The ship features stealth technology and is equipped with large- and medium-caliber dual purpose guns. Due to its shallow draft (up to 2 meters), the ship can perform missions in shallow waters, in river mouths, particularly delivering troops directly to the beach. At the same time, its design features enabled safe navigation in stormy conditions (at sea state up to 6) and use of weapons at sea state up to 4. Its water jets ensure speeds of up to 25 knots under any conditions, provide high maneuverability and controllability, reduce noise and running vibration, and are not prone to damage in shallow waters.

The Project 21630 vessels are equipped with radar and hull-mounted sonar. Their weapon system consists of a single A-190 100mm cannon and two AK-306 30mm anti-aircraft guns. The A-215 Grad-M artillery system with 40 122mm rockets is intended to provide fire support against positions onshore. Besides, these vessels are equipped with a variety of 14.5mm (2) and 7.62mm (3) machine guns. So far, the Russian Navy has commissioned three Project 21630 gunboats. The lead vessel Astrakhan entered active duty in 2008. The Buyan-class vessels were commissioned by the Russian Navy in the Caspian Sea to protect Russian borders.
