Tulgar has been delivered and is currently undergoing testing with Turkish F-16's.
Source?
Does this refer to all F-16 models to be tested?
Or is it probably the F-16 Block 30 Özgür, as the source code is available for software modifications.
The question doesn't belong here, but why doesn't Turkey buy 40 used F-16 Block 30s from the EU & Co and have them converted to the Özgür platform, which is much cheaper than ordering 40 new Eurofighters.
The advantage would be that most of the money would remain in the country and 40 used F-16 Block 30s converted to Özgür would be significantly cheaper than 40 new Eurofighter Tranche 4.
The main money should be invested in the development and production of KAAN instead of putting money into the pockets of other countries.
You don't have to retrain the pilots, maintenance crew etc. either.
And the airplane fires either US ammunition or Turkish ammunition, and most of the money in this case stays at home.
