What Is TUSAŞ KAAN? Turkey’s Homegrown Fifth-Generation Fighter Takes Flight
On February 21, 2024, a jet streaked across the skies above Ankara that no Turkish Air Force pilot had ever flown before — the KAAN, a domestically developed fifth-generation fighter built entirely by Turkish Aerospace Industries (TUSAŞ). In doing so, Turkey joined an elite club of nations capable of designing, building and flying their own stealth combat aircraft, a milestone that carries implications well beyond the country’s borders.

How KAAN Came to Be
The road to KAAN began in earnest in August 2016, when the Turkish Defence Industries Presidency (SSB) signed a development contract with TUSAŞ. The mandate was clear: design a true fifth-generation platform from scratch, not a derivative or a licensed product. TUSAŞ had to stand up entire engineering disciplines — stealth shaping, sensor fusion software, integrated modular avionics — that Turkey had never developed before.
Seven years of intense development followed. By late 2023, the aircraft completed its first engine runs on the tarmac. Then came February 21, 2024: a 13-minute maiden flight reaching 8,000 feet and 230 knots, followed three months later by a second flight pushing to 10,000 feet. A second prototype flew in November 2024, confirming the program’s momentum.
What Makes It a Fifth-Generation Fighter
The defining features of a fifth-generation platform are stealth, sensor fusion and supercruise capability. KAAN addresses all three. Its blended-body airframe and composite skin panels are shaped to minimize radar cross-section across a wide range of frequencies. Internal weapons bays — a hallmark of stealth fighters — keep missiles tucked away during ingress, removing the radar-reflective pylons that betray conventional jets. On the avionics side, a sensor fusion suite pulls data from radar, electro-optical systems and electronic warfare receivers into a single integrated picture for the pilot, reducing cognitive load in high-threat environments.
Two turbofan engines, each producing 13,150 kgf of thrust, push the aircraft past Mach 1.8 at altitude, with a +9G structural limit that matches the most demanding air-combat manoeuvring requirements.
The Strategic Stakes
Turkey’s F-16 fleet, while capable, is ageing. The Turkish Air Force needs a credible successor by the early 2030s, and KAAN is designed to fill that role. But the strategic value extends beyond domestic service. A fifth-generation fighter with competitive performance and no politically attached export restrictions is a compelling proposition for the growing list of countries that want modern air power but cannot — or will not — accept the strings that come with US or European suppliers. If BAYRAKTAR rewrote the drone market, KAAN aims to do the same in the fighter segment.
What Comes Next
The test campaign running through 2028 will cover internal weapons carriage, air-to-air refuelling qualification and full-envelope stealth validation. In parallel, TEI (TUSAŞ Engine Industries) is developing a domestic turbofan to replace the current foreign-sourced engines — the final piece in the self-sufficiency puzzle. When that engine matures, Turkey will have a fully sovereign fighter from airframe to powerplant, a capability fewer than a handful of nations can claim.
