The Falcon Turret was indigenously developed by King Abdullah II design and development bureau, KADDB, in close partnership with the Mechanology Design Bureau and IST Dynamics of South Africa. It also uses some British and Swiss subsystems. The Falcon Turret was first revealed in 2003. The intended platform for this turret is the Jordanian Al Hussein, Challenger 1, Main Battle Tank. Jordanian Army also operates TARIC, Centurions, M60A3 in Colled, Sheftan, Main Battle Tanks. These tanks can be also fitted with the Falcon Turret. This turret is also proposed for export customers. The Falcon is a low volume and reduced silhouette turret. It incorporates a Swiss RUAG Defense Systems 120 mm Slash L50 Smooth Board gun fitted with an auto loader. This gun is capable of firing all types of NATO 120 mm tank ammunition. It is superior to the British L11 120 mm rifled gun of the Al Hussein. The same Swiss RUAG CTG tank gun is used on Jordanian M60 Phoenix Main Battle Tank, which is upgraded version of the USM60A3. Maximum rate of fire is up to 8 rounds per minute. Up to 17 rounds can be stowed in the bustle auto loader. Loading mechanism and ready to use ammunition are separated from the crew. Turret bustle is fitted with blowout panels. Additional rounds are carried inside the hull. Secondary armament consists of coaxial 7.62 mm machine gun. This turret is fitted with the latest generation thermal imaging, surveillance, navigation and fire control systems. Remote operation of the turret enables full under armor protection for the crew members. Overall protection level is improved by reduced vehicle profile. Front of the turret is reinforced with composite armor. The Falcon turret has a built-in modular armor. Modules can be replaced when damaged or when more advanced armor is available. Turret is fitted with automatic fire suppression and NBC protection systems. The Falcon turret is fitted with auxiliary power unit based on a small diesel engine. Initial variant is known as the Falcon 1 AB9C4, while the improved variant is known as the Falcon 2 AB9C5. The Falcon 3 was under development. It was planned to be fitted with a new auto loader, which can accommodate more ready-to-use ammunition.
