T-625 GÖKBEY is a general-purpose helicopter designed, developed, and produced by Turkish engineers at TUSAŞ facilities, tailored to the geographic and climatic conditions of Turkey for use by the Turkish Armed Forces and Civil Aviation sectors.
The Indigenous Helicopter Program, aimed at meeting the general-purpose helicopter needs of the Turkish Armed Forces and other institutions with a unique platform, was launched with the decision of the Defense Industry Executive Committee (SSİK) on June 15, 2010. The program's budget and timeline were set by the SSİK decision on January 3, 2013, and the contract between SSM and TUSAŞ was signed on June 26, 2013.
The T625 GÖKBEY General Purpose Helicopter is being designed and produced using local resources, building on the knowledge, experience, and capabilities gained during the ATAK Program. The design and production of critical systems such as structural and avionics systems, transmission, rotor, and landing gear are being carried out using national resources. With its wide mission scope, the T625 GÖKBEY will be able to perform various tasks, including transport, VIP, cargo, air ambulance, search and rescue, and over-water transport.
As the first general-purpose helicopter developed and produced with domestic capabilities, T625 GÖKBEY successfully made its first flight on September 6, 2018. On April 19, 2023, the P1 prototype, powered by the TS1400 turboshaft engines developed and produced by TEI with national resources, successfully performed its first test flight.
Work continues for the certification of the helicopter by the European Aviation Safety Authority (EASA) and the Directorate General of Civil Aviation (SHGM). The T625 GÖKBEY, designed and produced by TUSAŞ, is progressing successfully through its testing and certification processes. The serial production of three T625 GÖKBEY helicopters is ongoing, and they will be delivered to the Gendarmerie General Command. With the national TS1400 Turboshaft Engines, the helicopter will be able to operate effectively in the most challenging climates and geographical conditions, at high altitudes and temperatures, during both day and night.
The preliminary design studies for the indigenous general-purpose helicopter began in 2010. The contract for the 6-ton class general-purpose helicopter project was signed on June 26, 2013, and the program schedule began on September 6, 2013. As part of the project, Alp Havacılık is responsible for producing and assembling landing gear, gearboxes, and dynamic components, while the Spanish company CESA (Empresa Española de Sistemas Aeronáuticos) was selected to supply hydraulic systems.
Initially, the T-625 was expected to weigh 5 tons and use two LHTEC CTS800 engines, as the same engine was used in the TUSAŞ T-129 ATAK helicopter. However, Turkish engine manufacturer TEI began developing the new generation TS1400 engine.
The first introduction of the helicopter was made on September 5, 2014, during the "Industrialization of Indigenous Helicopters" meeting in Ankara. The T-625 prototype made its first flight on September 6, 2018. On June 29, 2019, the T-625 prototype made its first fully equipped flight and was certified by the Directorate General of Civil Aviation. On April 22, 2023, the first test flight with the TS1400 engine took place.
The first delivery of the T625 GÖKBEY to the Gendarmerie General Command will take place on October 29, 2024, during the 101st anniversary of the Republic. It is reported that the GÖKBEY helicopters will be assigned to personnel transport, cargo, air ambulance, search and rescue, and training activities for the Gendarmerie General Command. Additionally, the delivery of 20 GÖKBEY helicopters, including 7 to the Land Forces Command, 4 to the Air Forces Command, 3 to the Gendarmerie General Command, 3 to the General Directorate of Security, and 3 to the Coast Guard Command, will be completed by 2026.
