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

Turkey was removed from the F35 fighter jet program after purchasing the Russian S-400 missile defense system, prompting Ankara to develop its own stealth fighter, the KAAN. This project is a strategic, industrial, and political effort by President Recep Tayyip Erdogan to modernize the Turkish Air Force and close the technological gap with regional rivals like Israel and Greece, which operate advanced aircraft including the F35 and Rafale.

The KAAN, also known as MMU, is Turkey’s first national stealth fighter prototype, featuring fifth-generation capabilities such as low radar signature, advanced sensors, and supersonic speed up to Mach 1.8. However, the program faces significant challenges, including reliance on American-made General Electric F110 engines and high development costs. Ankara has requested additional engine deliveries from the U.S. to accelerate prototype testing and expand the fleet.

Turkey’s air force remains largely dependent on aging F16s and F4s, highlighting the urgent need for modernization amid increasing regional tensions and military advancements by neighboring countries. Experts note that KAAN is still far from operational status and that Turkey continues to seek reentry into the F35 program, viewing KAAN as a long-term solution rather than an immediate replacement.

The project also serves Erdogan’s domestic narrative of Turkish technological sovereignty and military independence. Ankara has secured export deals for KAAN, including a contract with Indonesia for 48 jets over the next decade. Meanwhile, Israel views any Turkish airpower enhancement with concern, especially the potential return of Turkey to the F35 program, which Israeli Prime Minister Benjamin Netanyahu has publicly opposed due to Turkey’s ties with Hamas and the Muslim Brotherhood.

The U.S. administration under Donald Trump has indicated a willingness to reconsider Turkey’s F35 participation if Ankara abandons the S-400 system. This possibility raises regional security alarms, as it would restore Turkey’s access to a proven stealth fighter. Regardless of the outcome, Turkey is determined to advance KAAN as a symbol of its regional ambitions and military autonomy, even as it remains dependent on Western technology and approvals.
