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.[6] The development was completed after the field test ended in September 2008.
