The CN08 (Cannon 08) is a 120 mm 55-caliber smoothbore tank gun produced by Hyundai WIA. It is incorrectly known as the licensed production of the Rheinmetall Rh-120 L/55, but it was indigenously developed by the Agency for Defense Development and WIA (now Hyundai WIA) from 2003 to 2008 for the XK2 development project started in 1995. The development was completed after the field test ended in September 2008.[6][7]
