Turkey Advances Indigenous Stealth Fighter KAAN Amid F35 Exclusion and Regional Air Power Gap

Turkey was removed from the F35 program after purchasing the Russian S-400 missile defense system, prompting Ankara to develop its own stealth fighter jet, the KAAN. This project is a strategic effort by President Recep Tayyip Erdogan to modernize the Turkish Air Force, reduce the technological gap with regional rivals like Israel and Greece, and assert Turkey’s defense independence. Despite the ambition, KAAN remains dependent on American engines and is far from operational readiness.

The KAAN prototype first flew in 2024 and is designed as a fifth-generation, twin-engine fighter with advanced stealth, sensors, and armament capabilities, reportedly capable of speeds up to Mach 1.8. However, the program faces significant challenges, including high costs, reliance on foreign components, and the need for extensive testing and pilot training. Turkey’s current air fleet mainly consists of aging F16s and F4s, which are increasingly outdated compared to Israel’s operational F35 squadrons and Greece’s acquisition of F35s and Rafale jets.

Ankara views KAAN as a long-term solution while continuing to pressure Washington for reentry into the F35 program, which would provide immediate advanced capabilities that KAAN cannot yet match. The U.S. has indicated willingness to reconsider Turkey’s participation if it abandons the S-400 system. Israeli officials, including Prime Minister Benjamin Netanyahu, have publicly opposed Turkey’s return to the F35 program, citing security concerns over Erdogan’s ties to Hamas and the Muslim Brotherhood.

The KAAN project also serves a domestic political purpose for Erdogan, symbolizing Turkey’s technological sovereignty and military strength. Turkey has signed export agreements for KAAN with Indonesia and is exploring interest from other countries. Nonetheless, experts caution that developing a fully operational fifth-generation fighter is a complex, lengthy process, and Turkey’s defense industry still depends heavily on foreign technology.

The future of Turkey’s air power hinges on whether it can overcome these hurdles and whether the U.S. will allow its reintegration into the F35 program. Meanwhile, KAAN remains a potent symbol of Ankara’s regional ambitions and its desire to maintain an independent and assertive military posture despite ongoing technological and political challenges.
