The TAI/AgustaWestland T129 ATAK is a twin-engine, tandem seat, multi-role, all-weather attack helicopter based on the Agusta A129 Mangusta platform. It was developed by Turkish Aerospace Industries (TAI) in partnership with Leonardo S.p.A. The helicopter is designed for armed reconnaissance and attack missions in hot and high environments and rough geography in both day and night conditions.

The Agusta A129 Mangusta is an attack helicopter originally designed and produced by Italian company Agusta. It is the first attack helicopter to be designed and produced wholly in Europe. It has continued to be developed by AgustaWestland, the successor company to Agusta. It has been exclusively operated by the Italian Army, which introduced the type to service during 1990.
