The TAI/AgustaWestland T-129 (AgustaWestland designation AW729) is an attack helicopter currently under development for the Turkish Army. An enhanced version of the Agusta A129 Mangusta, the T-129's development is now the responsibility of Turkish Aerospace Industries (TAI), with AgustaWestland as the primary partner.

The ATAK Program was initiated with the aim to meet the Attack/Tactical Reconnaissance Helicopter requirements of the Turkish Land Forces Command (TLF) by the integration of high-tech avionic equipment, hardware and software which will be developed in Turkey.

The first flight of the P6 prototype marks an important milestone in the ATAK Program such that; being the first of a total of three T129 prototypes to be assembled in Turkey, it shows the level of technology achieved by Turkish Aerospace Industries, Inc.
