The South Korean K30 Biho (Flying Tiger) twin 30 mm self-propelled anti-aircraft weapon was developed to meet the operational requirements of the Republic of Korea Armed Forces for a highly mobile short range air defense system suited to the operational and terrain conditions of the Korean peninsula. It combines an electro-optically guided 30 mm gun system with a surveillance radar system on a K200 chassis. It supplements the K263A1 Chungung, a self-propelled 20 mm Vulcan system. The K30 is primarily built by Hanwha Defense Systems.
