T70 T70

As part of the program, 109 T70 Utility Helicopters will be developed in Türkiye based on Sikorsky Aircraft's S70i Helicopter through licensed production by Turkish Aerospace, the prime contractor, and Sikorsky, Aselsan, TEI, and Alp Aviation, the subcontractors. These helicopters will be delivered to six different users: Land Forces Command, Air Forces Command, Special Forces Command, Gendarmerie General Command, General Directorate of Security, and General Directorate of Forestry.


Under the program, the prime contractor Turkish Aerospace carries out the production, final assembly, testing, and integrated logistics support of all main components, including the cabin, cockpit, tail cone, horizontal and vertical tails, main and tail rotor blades of the T70 helicopters. Aselsan oversees the development and integration of the main avionics and the development of the helicopter cockpit (IMAS) in collaboration with Sikorsky, while TEI takes charge of the production of the T700 engine. Alp Aviation is responsible for the production and assembly of the landing gear, gearbox detail parts, and dynamic parts.


The Turkish Utility Helicopter Program aims to fulfill Türkiye's demand for utility helicopters, with the Turkish industry playing a crucial role in meeting both military and civilian needs domestically. As of January 2024, 14 helicopters have been delivered under the project, while production is underway for nine helicopters, and assembly activities continue for 19 helicopters.

Licensed Domestic Production

190 T70 general purpose helicopters are domestically manufactured and nationalized with original designs under license. The helicopter body, blades, landing gear, gearboxes and flight control parts, cockpit avionics and T700-TEI-701D engine are manufactured domestically.

National Modular Avionics Architecture

With the national modular avionics architecture and software capability, a flexible system solution is available meeting different needs. The architecture features provisions, expansion options and an adequate processor-memory potential. With the domestic flight software, foreign dependency has been reduced for avionics integrations. Domestic advanced Electronic Countermeasure systems include an enhanced self-protection feature against Radar, Laser and Heat-guided, and high operation capability.

Integrated Logistics Support

With the domestic manufacture and maintenance-repair capability, logistics support needed throughout the lifecycle of the helicopters will be provided fast and cost-effectively.
