It is pointless to buy those planes without source codes. And as i said it still negotiating. Yea thats right Turkey lvl 3 partner but investing at least 11 billion dollar to this project.
Why pointless? what special about Turkey? Is there a Turkish radar to integrate? AA missiles of Turkish origin to use? PGM? EW suit to install?
And no, the investment to the project is around 200mil, the procurement of final product is maybe of 11billlion.
