Turkey Finally Lands Its TAI T-129 Attack Helicopters

Turkey has been looking to modernize its attack helicopter fleet since the mid-1990s, but the process has mostly served as an object lesson in how not to buy defense equipment. This competition faced many difficulties; after numerous snafus, technology transfer and production issues, and canceled competitions, all 3 invited American manufacturers had abandoned the competition entirely.

Even the “final” round seemed imperiled, following reports of the Turkish military’s deep dissatisfaction with the choices; nevertheless, the competition survived long enough to pick a “winner”: an updated version of the A129 Mangusta. Now, signed industrial arrangements contracts with AgustaWestland allow the 12-year program to move forward at last. But Turkey didn’t just buy helicopters – they bought the model, lock, stock, and rotor…

At present, Turkey has to rely on 6 remaining AH-1W Super Cobra attack helicopters, and about 20-23 earlier model AH-1 Cobras, as its attack helicopter fleet. The earlier model Cobras lack some useful modern capabilities. Worse, low numbers and age-related availability issues are straining the fleet’s capacity, making operations in Turkey and Iraq’s Kurdish regions more difficult.

The new AH-1Z had come out on top in a previous replacement competition, but 4 years of negotiations with Bell Helicopter to jointly produce the AH-1Z Super Cobra failed in 2004, over major price differences and licensing demands.

The Turkish SSM responded by opening a fresh international competition in February 2005, but did so in a way that magnified the problems again rather than solving them. They were immediately confronted by serious objections from global manufacturers, which forced the SSM to change the RFP in May 2005. Even then, Bell Helicopter and Boeing looked at Turkish demands, and dropped out.

Defense Minister Gonul made the Turkish perspective clear long ago when he noted that “the goal is to co-produce the helicopters, not to buy them off the shelf.” The Houston Chronicle reported that bidding rules also included full access to the aircraft’s specific software codes, and a written guarantee from the provider’s government that there would be no political obstacles to Turkish exports of the licensed helicopters.

In July 2006, Turkish Defense Minister Vecdi Gonul announced that Turkey would continue talks with Denel of South Africa (AH-2A Rooivalk) and Agusta Aerospace of Italy (A129 International) for Turkey’s Land Forces Command’s Tactical Reconnaissance & Attack Helicopter (ATAK) Project. The Franco-German EADS Eurocopter (Tiger) and Kamov of Russia (Ka-50-2 Erdogan with IAI) were eliminated.

Neither of the finalists had been exported before, and at the time they were competing for co-production of 30 helicopters with options for another 20 more. That projected $1.6 billion contract was still well short of the 91 attack helicopters originally called for when the program began. Still, it was progress. In the end, a contract was signed in September 2007 for 51 “T129 ATAK” helicopters from AgustaWestland, plus another 41 on option under the same terms. Some of those options were exercised in 2010, when Turkey ordered 9 “basic model” T129s to reinforce its dwindling attack helicopter fleet.

Turkish Aerospace Industries is the prime contractor. Aselsan and AgustaWestland will be the subcontractors, under a collaboration agreement in which TAI shares ownership of intellectual property rights for the new A129 configuration with AgustaWestland. TAI will also become the sole source for the production of the whole fuselage, including final assembly and flight operations, and will be responsible for marketing the “T-129 attack helicopters” to the world.


The A129 Mangusta (trans. “Mongoose”) entered service with the Italian Army in 1989; AgustaWestland offered it as a base for the Franco-German Tiger partnership, but cooperation was declined in favor of a Franco-German R&D program. The current Italian service inventory is 60 machines, 15 of which are the more modern A129 International/AW129 standard with uprated engines (LHTEC replaced earlier Rolls Royce Gem) and rotors (5-bladed vs. 4), plus new weapons, avionics, and defensive systems. The other 45 Italian A129 CBT helicopters received rotor, transmission, weapon, defensive, and electronics upgrades under a multi-year contract signed in 2002.

This A129 family is notable for their low frontal profile, and offer a good mix of surveillance, gun and missile capabilities. A mast-mounted sight offers the potential for further improvements, but the type had not been successful in export competitions before the 2007 Turkish order. The A129 has seen service with Italian forces in Angola, Macedonia, Somalia, and Iraq.

Like the A129I, the Turkish T129 is powered by 2 Rolls Royce/ Honeywell LHTEC CTS800-4A turboshafts, each generating 1,361 shp. They can drive the helicopter to speeds of 269 kph/ 145 kts, and allow hover out of ground effect to 10,000 feet. Endurance is about 3 hours, with a maximum range of 561 km/ 303 nm.

The Turkish ASELFLIR 300T will replace the AW129’s Honeywell surveillance and targeting systems. The helicopter always has its 3-barreled 20mm chin turret, and certified weapons for its 4 side pylons include its 12.7mm machine gun pods, 70mm unguided Hydra and guided Cirit rockets, anti-tank missiles (TOW, Spike-ER, Hellfire), and Air-to-Air Missiles (Stinger, Mistral). Turkey is also working to develop and then certify its own UMTAS/LRAT anti-tank missile for the T129.
