   The new prototype light tank was revealed in 2013 during IDEX exhibition held in the Abu Dhabi. It was jointly developed by CMI Defence of Belgium and Doosan DST of South Korea.

   The new light tank is a combination of the K-21 infantry fighting vehicle chassis, mated with the newly-developed Cockerill XC-8 lightweight concept turret. This turret uses some technology of the Cockerill CT-CV turret. This new tank can be fitted with 105 mm or 120 mm high-pressure gun. This combination provides significant direct fire capability, based on relatively light and mobile chassis. Due to its lighter weight this tank is more strategically and tactically mobile, comparing with main battle tanks.

   The Cockerill 105 mm gun uses a wide range of ammunition, to suit tactical situation. It fires all standard NATO 105 mm rounds. Maximum indirect range of fire with HE rounds is up to 10 km. This gun is also compatible with Cockerill Falarick 105 gun-launched anti-tank guided missiles. These missiles are launched in the same manner as ordinary rounds. This missile has a semi-automatic laser guidance with tandem warhead. The Falarick 105 penetrates no less than 550 mm behind ERA. This missile is used to engage heavily-armored vehicles at long ranges.

   The Cockerill 120 mm smoothbore gun is intended to meet a more specialized anti-armor requirement. It fires all standard NATO 120 mm tank ammunition. This gun is also compatible with Falarick 120 gun-launched anti-tank missiles. These missiles have an effective range in excess of 5 km.

   Both guns are fitted with a bustle-mounted autoloader, which permits a three man crew. Both guns are fully-stabilized and use the same advanced fire control system. So this tank can fire accurately on the move.

   There is a coaxial 7.62 mm machine gun.

   Composite materials were extensively used in the hull design in order to save weight wherever possible. The front arc provides protection against 30 mm armor-piercing rounds. All-round protection is against 14.5 mm armor-piercing rounds and artillery shell splinters. Vehicle is also fitted with automatic fire suppression system.

   The crew includes commander, gunner and driver.

   Vehicle is powered by a new Doosan D2840LXE turbocharged diesel engine, developing 750 hp. This engine is more powerful than that, used on the K-21 IFV. Engine is mated to a fully automatic transmission. Vehicle has a hydropneumatic suspension and advanced running gear. The new tank retains its amphibious capability at full combat weight. Only minimum preparation is required in order to ford water obstacles. Automatic floatation bags are activated before entering the water. On water this tank is powered by its tracks. Amphibious speed on water is up to 7 km/h.

   Later a similar K21-105 light tank was introduced. It was developed by the same companies. It is a combination of the K21 IFV with an older CT-CV 105 HP turret, armed with a 105 mm gun.
