The TAI/AgustaWestland T129 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 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 high-tech avionics, air-frame modifications, and weapon systems onto the combat proven AgustaWestland A129 airframe, with upgraded engines, transmission and rotor blades. It is in use by the Turkish Army, and is being offered to other services.
