Turkiye's fifth-generation fighter aircraft, โKAAN,โ has successfully completed ground tests assessing the capabilities of its afterburner engine, signaling readiness for its third flight test in the near future.
That is going to be a very advanced engine with reduced heat signature and thrust vectoring. Turkey has never built an engine this size let alone complexity so nothing is certain but official statements in this matter lead me to believe that it's expected around 2030. That will make Kaan truly 5th gen.
