One of the most significant milestones in Turkish aviation history, the HÜRJET jet trainer aircraft, has once again demonstrated its resilience and advanced engineering capabilities. Developed under the coordination of the Presidency of Defence Industries by Turkish Aerospace Industries (TAI), two HÜRJET prototypes were deployed to Erzurum to undergo comprehensive cold weather testing under extreme winter conditions. Ground tests were successfully conducted at temperatures dropping as low as -21 degrees Celsius.

The test campaign was not limited to low-temperature exposure alone. Thanks to Erzurum’s high-altitude geography, HÜRJET’s performance in demanding altitude conditions was also thoroughly validated. Following the completion of ground tests, flight tests were carried out, confirming that the aircraft’s engine, avionics, and flight control systems operated efficiently and reliably despite harsh environmental challenges. These results clearly demonstrated HÜRJET’s capability to perform missions across diverse climates and terrains.

Successfully completing cold weather and high-altitude tests proved that HÜRJET is not limited to ideal operational environments. The absence of system freezing, performance degradation, or operational issues confirmed the aircraft’s maturity level and compliance with international aviation standards. The fact that two prototypes passed these rigorous tests further highlighted TAI’s strong engineering expertise and robust development process.

To date, HÜRJET has completed approximately 400 sorties as part of its test and development program. Following initial domestic orders, the export agreement signed with Spain and expected additional international demand have accelerated preparations for serial production. TAI aims to produce up to three aircraft per month through a dedicated supplier network. Featuring a single-engine and tandem cockpit configuration, HÜRJET is designed to play a critical role in modern fighter pilot training. The aircraft will also be capable of performing advanced lead-in fighter training, air patrol missions, and aerobatic display roles.
