So basically you don't have a fully working production model in service.
What a jealous troll
only USA and Turkiye have developed unmanned stealth Fighter Jet
others including China dont have even a prototype
You said weak Ukraine doesn't have an Air Force to protect TB2s from Russian Fighter jets.
I said that's the whole point of using UCAVs,to free your Air Force to operate elsewhere or in order not to risk pilot lives and expensive aircraft or because you don't have the money to operate an Air Force.
According to ignorant and jealous troll
btw it has nothing to do with money
it has to do with Syrian S300s against Turkish F-16s ( not to risk to lose Pilots and expensive F-16s )
