The TAI/Leonardo T129 ATAK is a twin-engine, tandem-seat multi-role attack helicopter developed by Turkish Aerospace Industries (TAI) in partnership with AgustaWestland (now Leonardo Helicopters). Based on the Italian A129 Mangusta platform, the T129 represents a major industrial achievement for Turkey, integrating indigenous avionics, weapon systems, and airframe modifications to meet the specific requirements of the Turkish Armed Forces. The program began with negotiations on March 30, 2007, leading to the aircraft's first flight on September 28, 2009. Production began that same year at TAI's facilities in Ankara, Turkey.
Technically, the T129 is optimized for "hot-and-high" environments and rough geography. It is powered by two LHTEC CTS800-4N (T800-4A family) turboshaft engines, each producing approximately 1,014 to 1,024 kW (roughly 1,373 shp). These engines, combined with an upgraded transmission and rotor blades, allow the helicopter to reach a maximum speed of 281 km/h and a range of 537 km. The aircraft has a maximum takeoff weight of 5,655 kg and an empty weight of 2,900 kg. Its operational ceiling reaches 4,572 meters out of ground effect, with a maximum climb capability of nearly 6,096 meters.
In terms of armament, the ATAK is equipped with a nose-mounted 20 mm three-barrel rotary cannon with 500 rounds. Its external stores include indigenous weapons such as CİRİT 70 mm laser-guided rockets and UMTAS/L-UMTAS long-range anti-tank missiles. It can also carry up to 76 unguided 70 mm rockets and eight air-launched Stinger missiles.
Following its entry into service in 2014, the T129 has been utilized by the Turkish Army, the Gendarmerie General Command, and the General Directorate of Security. It saw its first combat deployment on April 25, 2015, and has played a critical role in operations across Iraq and Syria. One T129 was lost to YPG anti-aircraft fire on February 10, 2018. Beyond Turkey, the Philippines acquired six T129s for its 15th Strike Wing via a $269 million contract, with deliveries occurring between 2021 and 2023. While a contract for 30 aircraft was announced for Pakistan in 2018, deliveries have been hindered by U.S. engine export licensing issues. As of 2023, TAI has produced over 100 airframes, including seven prototypes, with 96 units delivered.
