Project advances with parallel testing and future integration of domestic engine; country aims for self-sufficiency and strategic exports
Turkey has taken another decisive step in its ambitious combat aviation program by ordering the sixth prototype of the fifth-generation KAAN fighter jet, as announced by the Presidency of Defense Industries (SSB).

According to the defense portal Ulusavunma.com, the new order will allow Turkish Aerospace Industries (TAI) to carry out a series of critical test phases simultaneously, including wind tunnel experiments, environmental stress tests, avionics validation, high-speed taxi tests, and runway runs.

These activities are considered essential to prepare the aircraft for serial production and eventual integration into the Turkish Air Force.
The SSB emphasized that deliveries to the armed forces will occur in phases, with successive production blocks incorporating progressively advanced capabilities.
Domestic Engine and Self-Sufficiency
One of the most significant milestones of the program is the integration of an engine developed entirely in Turkey. According to defense officials, the process remains on schedule. Future versions of the aircraft — such as Block 30 and Block 40 — are expected to phase out the U.S.-made General Electric F110 engine and adopt a domestic powerplant, with testing to follow as the technology matures.
Launched in 2010, the KAAN project has become a symbol of Turkey’s push for defense self-sufficiency and reducing reliance on foreign systems. The fighter is a twin-engine stealth aircraft with supersonic capability and advanced maneuverability, designed for both air superiority and strike missions.
Progress Following F-35 Program Removal
KAAN development accelerated after Turkey was removed from the U.S. F-35 program in 2019 due to its acquisition of the Russian S-400 air defense system. Originally intended as a complementary platform to the F-35, KAAN has since become the cornerstone of Turkey’s air power strategy.
In 2024, the first KAAN prototype successfully completed its maiden flight over Ankara, flying for 13 minutes — two years ahead of schedule. Turkish officials hailed the milestone as a breakthrough in the country’s aerospace ambitions.
