The Krivak class is a series of guided missile corvettes originally designed and built by the Soviet Union. These ships are primarily used for anti-submarine warfare and coastal defense. They are characterized by their stealthy design, which reduces radar visibility, and their ability to operate in various maritime environments. The Krivak class has been exported to several countries and has undergone various upgrades over the years. They typically feature a combination of missile systems, torpedoes, and anti-aircraft weapons, making them versatile vessels in naval operations. Notable variants include the Krivak I, Krivak II, and Krivak III.
