T129 ATAK Turned an Italian Design Into a Turkish Export Success

The T129 ATAK helicopter began life as somebody else’s design. When Türkiye picked the AgustaWestland A129 Mangusta as the basis for its attack helicopter programme in 2007, the Italian airframe was already a quarter-century old and had never been exported. Eighteen years later the Turkish derivative has been built in far greater numbers than its parent, fought through years of counter-terrorism operations in mountainous terrain, and found buyers in Southeast Asia and West Africa. It has also run headlong into the limits of what a licence-built platform with an American engine can achieve on the export market.

This guide covers the programme’s history, the verified specifications, the weapons fit, the variants, every current operator, and the engine problem that killed the largest export order the T129 ever attracted.

Where Does the T129 ATAK Helicopter Come From?

Türkiye spent the 1990s and early 2000s trying and failing to buy attack helicopters. A long-running competition that at various points involved the AH-1Z King Cobra, the Ka-50-2 Erdogan and the A129 finally produced a decision on 30 March 2007, when AgustaWestland was announced as the winner of the ATAK programme. A contract worth roughly 1.2 billion dollars followed on 7 September 2007, covering 50 firm helicopters for the Turkish Land Forces Command with options for 41 more.

The structure of the deal mattered more than the airframe. Turkish Aerospace (TUSAŞ) took the role of prime contractor, with AgustaWestland and ASELSAN working as subcontractors. Production helicopters would be assembled in Türkiye, and the mission computer, targeting system, cockpit displays and much of the avionics would be Turkish. TUSAŞ also secured marketing rights for the type outside Italy and the United Kingdom, which is why the T129 rather than the A129 went on to compete for orders in Pakistan, the Philippines and Nigeria.

Compared with the original Mangusta, the T129 received uprated engines, a new five-bladed main rotor system inherited from the A129 International configuration, a strengthened transmission and an entirely different mission equipment package built around ASELSAN systems. The first TUSAŞ-assembled aircraft flew in 2011, and on 22 April 2014 the company formally handed over the first serial-production T129 to the Turkish Land Forces. Deliveries to the Turkish Armed Forces and security services have continued for over a decade since, with the fleet passing well beyond the original 50-aircraft commitment once Gendarmerie, Police and export orders were added.

What Are the Verified Specifications?

TUSAŞ publishes a technical data sheet for the T129, which makes the core figures unusually easy to verify for an attack helicopter. The aircraft sits in the 5-tonne class, well below the 10-tonne AH-64E Apache but with a power-to-weight ratio that the manufacturer has long promoted as the key to its hot-and-high performance. The type was designed with the eastern Anatolian mountains in mind, where thin air punishes heavier gunships.

The CTS800-4A engine is produced by LHTEC, a joint venture between Honeywell of the United States and Rolls-Royce. Each engine is rated at around 1,360 shaft horsepower according to published figures, giving the lightweight airframe generous margins at altitude. That American parentage, as later sections show, is also the single biggest constraint on where the T129 can be sold.

Which Weapons Does the T129 Carry?

The T129’s armament package is where the Turkish content is most visible, because nearly all of it comes from Roketsan and ASELSAN rather than from the original Italian design.

Fixed armament is a 20 mm three-barrel rotary cannon in a nose turret, fed by 500 rounds and slaved to the crew’s helmet-mounted sights. Four stub-wing stations carry the disposable stores, and TUSAŞ quotes a typical maximum mix along the following lines:

• UMTAS / L-UMTAS — up to eight of Roketsan’s long-range anti-tank missiles. UMTAS is the imaging-infrared, fire-and-forget version; L-UMTAS is laser guided. Both give the T129 a stand-off anti-armour reach of roughly 8 km according to Roketsan.
• CİRİT — up to sixteen 70 mm laser-guided rockets, a Roketsan product that converts cheap unguided rocket geometry into a precision weapon for soft and lightly armoured targets. CİRİT became one of the T129’s signature weapons and has been marketed alongside it in every export campaign.
• Unguided 70 mm rockets — up to 76 in pod configuration for area suppression.
• Stinger ATAM — up to eight air-to-air Stinger missiles in twin launchers for self-defence against helicopters and slow air targets.

The sensor that ties this together is ASELSAN’s AselFLIR-300T electro-optical targeting system, mounted above the gun turret, which handles day and night target acquisition and laser designation for the guided weapons. ASELSAN also supplies the avionics backbone and, on later aircraft, the self-protection suite. The integration of national missiles onto a national sensor chain is the practical difference between the T129 and a straightforward licence build, and it is the part of the programme Turkish industry points to most often.

How Do the T129A and T129B Variants Differ?

Turkish Land Forces aircraft were delivered in stepped configurations rather than a single standard.

The T129A, sometimes called the EDH (Early Delivery Helicopter), was an interim batch of nine aircraft agreed in 2010 to get gunships to the army faster than the baseline schedule allowed. These carried the gun and unguided rockets but lacked the full guided-missile capability, and they were later cycled back for upgrades.

The T129B is the definitive configuration, with the complete weapons fit including UMTAS, L-UMTAS, CİRİT and Stinger. Within the 50-aircraft Land Forces order the T129B was itself split into Phase-1 (29 aircraft) and Phase-2 (21 aircraft) standards. The Phase-2 aircraft add a substantially upgraded ASELSAN electronic warfare suite — a new radar warning receiver, a laser warning receiver and a radio-frequency jammer — along with the ability to employ the fire-and-forget UMTAS and reinforced main landing gear attachment points to handle higher operating weights. The first Phase-2 prototype flew in late 2019, and Phase-2 aircraft have been the production standard for recent domestic and export deliveries.

Who Flies the T129 Today?

The Turkish Land Forces Command remains by far the largest operator and has used the type intensively in operations in southeastern Türkiye and in cross-border operations in northern Iraq and Syria. The Gendarmerie General Command operates its own growing fleet for internal security missions, with Turkish reporting tracking deliveries into the high teens.

The third domestic operator is the more unusual one. The Turkish National Police ordered nine Phase-2 configuration aircraft and began operating them in 2021, which made it the first civilian law-enforcement organisation anywhere known to fly dedicated attack helicopters. The Police aircraft are a visible marker of how deeply the type has been absorbed across Türkiye’s security services.

Philippines. Manila signed for six T129Bs in July 2020, a deal reported at around 270 million dollars, and the United States granted the export licence for the engines without the drama that surrounded other campaigns. The first pair arrived in March 2022, were formally turned over that April, and the Philippine Air Force received the fifth and sixth aircraft in May 2024, completing the order. The helicopters serve with the 15th Strike Wing and have already been employed in operations against insurgent groups in the country’s south.

Nigeria. Abuja followed with its own six-aircraft order, also reported at roughly 270 million dollars. The first two T129s were delivered to the Nigerian Air Force in November 2023, with the remainder following in batches through 2024. Nigeria’s fleet is intended for counter-insurgency work against Boko Haram and armed criminal groups, an operating profile close to the mission the helicopter was refined for at home.

Why Did the Pakistan Deal Collapse?

For a period the T129’s biggest export story was Pakistan. In 2018 Islamabad signed for 30 helicopters in a deal valued at about 1.5 billion dollars, at the time the largest single export contract in Turkish defence industry history. The aircraft never arrived.

The problem was the engine. Because the CTS800-4A is subject to United States export controls, every T129 sale needs an American licence, and Washington — whose relations with both Ankara and Islamabad were deteriorating for different reasons, including Türkiye’s S-400 purchase — declined to grant one for the Pakistani order. The deadline was extended repeatedly while Ankara lobbied for approval, but in January 2022 a Pakistan Army spokesman confirmed the procurement had been dropped. Pakistan turned to China’s Z-10ME instead.

The episode became the defining case study in Turkish debates about supply-chain sovereignty, covered in more depth in our guide to how ITAR and US export controls shape Turkish defence exports. The contrast is hard to miss. The same engine, the same helicopter and the same seller produced a blocked licence for Pakistan and an approved one for the Philippines, a US treaty ally. The lesson Ankara drew was that any platform with critical American content carries a foreign-policy veto inside it, and that conclusion now drives the country’s engine-development programmes — including TEI’s TS1400 turboshaft developed for the T625 Gökbey utility helicopter, the first step toward powering Turkish rotorcraft with Turkish engines.

Combat Record and the Fleet’s Place in Turkish Aviation

The T129 has been one of the most heavily used attack helicopters of its generation. Turkish operations against the PKK in the southeast and across the Iraqi border, and later operations in northern Syria, gave the fleet a sustained operational tempo from 2015 onward. Losses have occurred, including to man-portable air defence systems in Syria, and the experience directly informed the Phase-2 electronic warfare upgrade.

Within Turkish military aviation the T129 sits alongside a rotary-wing industrial base that TUSAŞ has been building in parallel, from the licence-produced Black Hawks of the T70 programme to the clean-sheet Gökbey. The ATAK line at Kahramankazan near Ankara gave TUSAŞ its production experience in armed rotorcraft, and the design authority the company accumulated through the Phase-2 work fed straight into what came next.

What Comes After the T129?

The answer is the T929 ATAK-2, and it is not an upgrade but a different helicopter entirely. Where the T129 is a 5-tonne platform, the T929 is an 11-tonne heavy attack helicopter in the class of the AH-64 or Mi-28, developed by TUSAŞ under a 2019 contract with Türkiye’s SSB. The prototype made its maiden flight on 28 April 2023 powered by Ukrainian Motor Sich TV3-117 engines of around 2,500 shp each, an interim solution while Türkiye works toward a domestic powerplant in that class — precisely so that no future ATAK-2 customer can be lost to a third country’s licence decision.

Turkish officials have spoken of initial T929 deliveries to the Land Forces around the mid-2020s, though the programme’s timeline should be treated as fluid until series production is confirmed. The T129 will not disappear when the T929 arrives; the two types are sized for different missions, and the lighter helicopter’s operating costs and hot-and-high agility keep it relevant for the reconnaissance and escort roles it was bought for. Production for export customers remains open, and TUSAŞ continues to market the T129 in Southeast Asia, Africa and the Gulf — to countries where, as every campaign since 2018 has shown, the first question any buyer now asks is about the engine licence.
