They’ve had F-16s for years, producing most of them domestically (under license). Maybe some upgrades?
Turkey’s been developing their own “5th gen” fighter, and they do have a pretty decent domestic military industrial base, but they got barred from purchasing the F-35 in 2019 when they bought an S-400 system from Russia - I wonder if he wants those. It’d need some US congressional cooperation to make happen, though.
