The main aim of the Hürjet project is to replace the Turkish Air Force's T-38 trainer aircraft fleet -- consisting of 70 aircraft -- and to meet the needs of potential international customers, as noted on the Turkish Aerospace Industries' website.
In the project, Hürjet's maximum altitude is set at 45,000 feet (14 kilometers), along with its 3,000-kilogram (6,600-pound) payload and a maximum speed of Mach 1.2.
