S400 will be intregated in Turkish network, only thing what will use data is Turkish software, so still not understand how a single direction information will be able to hack Turkish software :D .
Impossible, we are talking about high tech defence product. Only thing that will be done is translating Russian software to Turkish console. Ther is no data-link and not possible. Second batch S-400 with ToT in software will be possible.
Maybe Tumosan use bigger Turbo, that means Turbo that will need more maintenance. Engines with more capacity will have more torque with out bigger turbo.
The question will be can you keep it on track? All that fighers and weapons need to be maintenance and is not cheap. All that weapons need to be pay, your friends don't want a broken country.
Overhiped nothing more, our F16 will be upgrade with last technology, it will be better then the Viper radar. Data-link and new sensor package.
Like a F35 is a miracle machine, it fly like F16 with AWACS and data-link. Only edge advantage with stealth. You say it yourself weak countries with...
You goverment will take both, in terms of tactical chosen one will be TB2. TB2 is cheaper, you will aquire Anka as naval version. Maybe even AKSUNGUR will be Malaysian choose.
