What Is TUSAŞ T70? How Turkey Turned a Licensed Helicopter into a Domestic Industrial Platform
109 helicopters. Six agencies. One programme. The T70 represents Turkey’s largest single rotary-wing acquisition, a co-development and licensed production arrangement with Sikorsky that goes well beyond assembling an S-70i under a Turkish flag. TUSAŞ serves as prime contractor, bringing in ASELSAN for avionics, TEI for the powerplant and a network of domestic suppliers for airframe components — building genuine industrial capability at each step rather than simply transferring the finished product.

What Turkey Actually Built
Licence production in defence procurement ranges from pure assembly of imported kits to genuine co-development with meaningful knowledge transfer. The T70 sits at the more substantive end of that spectrum. Turkish inputs include airframe structural components designed and manufactured domestically, ASELSAN-developed avionics systems, the T700-TEI-701D turboshaft engine produced by TEI under a General Electric licence with increasing Turkish content, a domestically produced transmission system and landing gear. The result is a helicopter where the transfer of manufacturing know-how has created industrial skills that extend to the next programme — GÖKBEY, ATAK-2 and beyond.
Six Agencies, One Standardised Platform
Distributing 109 helicopters across six distinct government and military end-users — the Turkish Land Forces, Gendarmerie, Coast Guard, Police, Presidential communications unit and civilian agencies — creates significant economies of scale in training, maintenance and spares. A pilot certified on T70 in one service can transition to a T70 in another. A spare transmission component sourced for the Land Forces batch can supply a Coast Guard aircraft grounded at a remote port. Fleet standardisation at scale is one of the underappreciated levers of military readiness, and the T70 programme was structured to exploit it deliberately.
Mission Spectrum
T70’s mission list reflects the breadth of its customer base: troop transport and assault support for the Land Forces, external cargo lift and medevac across services, search and rescue operations in both land and maritime environments, maritime patrol for the Coast Guard, and general utility transport for civilian agencies. This versatility — managed through modular role equipment packages rather than dedicated variants — makes each aircraft in the 109-strong fleet more productive over its operational life.
