The TF-X (Turkish Fighter - Experimental) is a proposed all-season air superiority twin-engine fighter developed by Turkish Aerospace Industries (TAI) in collaboration with BAE Systems. The aircraft is expected to replace the Turkish Air Force's F-16 Fighting Falcons and to be exported to foreign air forces. The Turkish National Defense Ministry has stated that TF-X will make its first flight by 2023, but this was later delayed to 2025.
