Project 11661K (Gepard II)

The Project 11661K Gepard-class is a series of frigates/corvettes designed for multi-role missions including anti-surface, anti-submarine, and air defense. These vessels feature a stealthy hull design and are equipped with a comprehensive suite of weaponry and sensors.

Conceived in the late 1980s as a successor to the Soviet Koni and Grisha-class frigates, the Project 11661 class was designed to secure littoral zones and protect maritime borders. The heavily modernized Project 11661K variant, Dagestan, entered service with the Russian Navy's Caspian Flotilla in 2012, distinguished as the first Russian warship equipped with the Kalibr-NK cruise missile system. In October 2015, Dagestan achieved operational prominence by launching Kalibr cruise missiles from the Caspian Sea against targets in Syria. Today, the Russian vessels remain active in the Caspian Flotilla, while the design's legacy is bolstered by several modified Gepard 3.9 export variants currently serving in the Vietnamese Navy.
