The TAI/AgustaWestland T129 ATAK is a twin-engine, tandem seat, multi-role, all-weather attack helicopter based on the Agusta A129 Mangusta platform. The T129 was developed by Turkish Aerospace Industries (TAI) with partner AgustaWestland. The helicopter is designed for advanced attack and reconnaissance missions in hot and high environments and rough geography in both day and night conditions. The ATAK programme was begun to meet the Turkish Armed Forces' requirements for an attack and tactical reconnaissance helicopter. The T129 is the result of the integration of Turkish-developed avionics, airframe modifications, and weapon systems onto the AgustaWestland A129 airframe, with upgraded engines, transmission and rotor blades. It is in use by the Turkish Army and other services including the Turkish Gendarmerie. The helicopter has a unit cost of roughly US$50 million. The T129 ATAK is optimized for "hot and high conditions", performance requirements against challenging geographical and environmental conditions in night and day operations. It has several key improvements over the original A129 inline with the requirements of the Turkish Army. The helicopter is equipped with the Hunter Kaska integrated control system specially designed for the helicopter. The system enables the automatic orientation of target detection and weapon systems to the pilot's line of sight with high tracking accuracy. The helicopter is also equipped with a dedicated electro-optical FLIR system ASELFLIR-300T for multi-purpose missions manufactured by the Turkish company Aselsan. The helicopter also equipped with advanced electronic warfare and countermeasure systems which increase survival capabilities in combat situations. These systems include a Radar Warning Receiver (RIAS), Radar Frequency Mixer (RFKS) and a Laser Receiver (LIAS) in addition to an automatic Countermeasure Firing System (KTAS). The ATAK can be used in the anti-armour, armed reconnaissance, ground attack, escort, asymmetrical, fire support and short range anti-aircraft roles. The T129 ATAK is equipped with a 20 mm three-barrel rotary cannon in a nose turret with 500 rounds of ammunition. It can also be equipped with up to 8 UMTAS 160 mm long range anti-tank missiles, 76 unguided 70mm rockets for close air support, 16 CIRIT 70 mm missiles and 8 air launched Stinger short range air-to-air missiles. The helicopter features also include high maneuverability, low visibility, sound and radar silhouette, high impact resistance and ballistic tolerance.
