The T129 ATAK is an attack helicopter variant of the AW129 Mangusta developed by AgustaWestland for the Turkish Land Forces. The T129 Center Body Tailpipe achieves better than a 90% reduction in IR signature from all view angles versus the signature that would be achieved with a simple tailpipe. The T129 is marketed internationally by Turkish Aerospace Industries (TAI) and AW, and the T129 CBT is supplied standard with each aircraft.
