Turkey’s goal is to develop its own indigenous stealth fighter which will replace the F-16s in service
While the Turkish Air Force currently flies F-16s and some F-4s and is set to receive around 100 F-35s, the concept for TF-X is that it would be more heavily tilted towards the air superiority mission , as a F-22-class combat aircraft for the mid-2020s
While there is a requirement for a predicted 250 TF-X fighters for the Turkish Air Force itself
