Project 21630 Buyan-class artillery corvette

Project 21630 Buyan is the original Russian Buyan-class river-sea artillery corvette, built by Almaz Shipbuilding for Caspian Flotilla service. The three ships combine a 100 mm gun, 122 mm Grad-M rocket launcher, 3M-47 Gibka launchers for Igla missiles, and AK-630 close-in defenses on a shallow-draft hull designed for coastal operations.

USNI describes the Project 21630 ships as carrying 3M-47 Gibka launchers for Igla short-range surface-to-air missiles, so the class has a point-defense air-defense layer in addition to its gun and rocket armament.
