Washington, DC, January 1 - In a significant development for U.S.-Turkey defense relations, President Donald Trump announced in late December 2025 that his administration is very seriously considering approving the sale of F-35 Lightning II stealth fighter jets to Türkiye. This potential reversal comes years after Türkiye's removal from the F-35 program in 2019 due to its acquisition of Russian S-400 air defense systems, which raised concerns over compatibility and security risks to the advanced fifth-generation aircraft. Trump's remarks, made during a meeting with Israeli Prime Minister Benjamin Netanyahu, underscore a warming bilateral tie, with ongoing discussions aimed at resolving lingering issues surrounding the S-400. A potential F-35 deal could bridge Türkiye's interim air superiority needs while reinforcing NATO alliances, as Ankara seeks to modernize its fleet amid regional challenges.
Türkiye's pursuit of the F-35 aligns with its broader strategy to maintain a robust air force capable of fifth-generation operations. The Lockheed Martin F-35, renowned for its stealth capabilities, sensor fusion, and network-centric warfare features, represents a proven platform already in service with multiple NATO partners. Reintegration into the program would allow Türkiye to acquire these cutting-edge jets, potentially filling a capability gap as its aging F-16 fleet approaches phased retirement. Diplomatic efforts have intensified, with U.S. officials noting productive talks on addressing the S-400 impediment, paving the way for possible reinstatement and F-35 deliveries in the coming years.
Parallel to these international negotiations, Türkiye continues steady progress on its indigenous KAAN fighter jet program, developed by Turkish Aerospace Industries (TAI). The KAAN, a fifth-generation stealth aircraft designed to replace F-16s starting in the 2030s, has advanced through prototype assembly and ground testing. Multiple prototypes are under construction, with maiden flights anticipated in 2026, followed by intensive flight trials and system integrations. Initial blocks will utilize General Electric F110 engines, while long-term plans focus on domestic powerplant development for full operational capability by the early 2030s.
This dual-track approach, potential F-35 acquisition alongside KAAN development, highlights Türkiye's commitment to strategic autonomy in defense aviation. While the F-35 offers immediate access to mature fifth-generation technology, the KAAN embodies national ambitions for self-reliance in advanced fighter jet production. As geopolitical dynamics evolve, the outcome of U.S.-Türkiye talks on F-35 sales could influence regional air power balances, with both nations emphasizing mutual security interests within the NATO framework.
