You are talking about multi-billion fighter program, not a drone, again, there are no guaranteed it's going to materialised when you see big name like Lockheed and Mitsubishi failed to materialise their own fighter platform...
Mitsubishi X-2 is a 14 m platform which lack 5th gen features
X-2 is like twin engine variant of Turkish HURJET ( 13,6 m ) ....
KAAN Fighter Jet has already materialised ...
-- The second prototype will have a few fixes to the platform for better aero dynamics
-- Turkish Aerospace Industries has great experience and state of the art facilities to produce KAAN Fighter Jet with zero error of production quality
-- Turkiye has enough technology to equip the KAAN Fighter Jet with AESA Radar , EOTS , IRST , EW Suite , HMDS , DIRCM , Missiles , etc
The only thing that needs to be discussed here is time.
KAAN Fighter jet may be delayed for a few years but KAAN will eventually become the Turkish Air Force's most modern strike power , maybe in 2030 maybe in 2035 ... but sooner or later
We are wait for indigenous 35.000 lbf turbofan Engine ... nothing else
There has not been a single Turkish military project that has failed in the last 20 years
Turkiye needs interim solution until the KAAN Fighter Jet squadrons enter service in 2030-2035 period
Turkiye can buy 24 Eurofighter Jets from Qatar or S.Arabia to meet the urgent need as soon as possible
Some sources also talk about this possibility.
