Turkey Advances T-70 Helicopter Deliveries: Overcoming Program Challenges

September 18, 2025

Turkey moves ahead with T-70 deliveries despite program challenges

ISTANBUL — Turkey Welcomes New T-70 Helicopter to Its Air Force

In a significant development, Turkey has officially welcomed the latest T-70 utility helicopter into its Air Force, marking the event with a ceremony at the 3rd Main Jet Base. This helicopter, tailored for Combat Search and Rescue (CSAR) operations, represents the continued expansion of the Turkish Utility Helicopter Program (TUHP), which has now seen 31 of these aircraft delivered to various military and security branches.

Uncertain Future for the TUHP

Despite the recent induction, the future of the TUHP is filled with uncertainty. Initiated in 2007 with the aim to build on the success of the T129 ATAK project, the TUHP intended to produce up to 600 helicopters. This ambition was set through collaborations among Turkish Aerospace (TUSAŞ), Sikorsky, and several local subcontractors. Nevertheless, after significant delays and nearly two decades into the project, there is talk of possibly ending the program prematurely.

Originally, the plan involved acquiring 109 helicopters to fulfill roles in general utility, combat search and rescue, and firefighting for six different end-users: the Land Forces, Air Force, Gendarmerie, Special Forces, Police, and the Directorate of Forestry. However, it seems the production might be halted after only 39 helicopters have been completed.

Features of the T-70 Helicopter

The T-70 model is a domestically adapted version of the Sikorsky S-70i Black Hawk helicopter. It features T700-TEI-701D engines produced by TEI, and includes advanced avionics developed by ASELSAN, such as mission computers, multifunction displays, and a locally developed IFF Mod 5/C responder. Essential components like rotor heads and transmissions are manufactured by Alp Aviation.

Reasons Behind the Production Delays

The delays in production have been linked to several factors, including a shift in operational needs—particularly the increased use of armed UAVs which has reduced the demand for helicopter transport of troops—as well as repercussions from U.S. sanctions on Türkiye following its acquisition of the S-400 system.

Lockheed Martin, the parent company of Sikorsky, noted in its 2024 annual report that these sanctions adversely affected its capacity to fulfill TUHP contracts. This led to a partial suspension of work in October 2024 and incurred a financial loss of $95 million.

Further discussions in a Summer 2025 Earnings Call revealed a tentative agreement to restructure the TUHP, yet the exact path forward still remains unclear.

Advancements with the T925 Heavy Utility Helicopter

Amidst these challenges, Turkish Aerospace is pushing forward with the development of the T925 Heavy Utility Helicopter, a domestic alternative designed to transport up to 19 passengers or four tons of cargo, suitable for firefighting missions. The T925 is anticipated to take its first flight in 2026, with plans for it to enter service by 2028.
