I agree about the hight price tag and that yankees will be big hinderance as they own the patents.
But we dont know the exact terms of contract of TOT between yanks and the Turks.
Same as French Agosta - 90B is fully liscenced to Pakistan,and Pakistan can build and sell them....
But the catch is the AIP will come from France and that will be sent only if France approves of the country Pakistan wants to sell the Submarine to.
Turks may be in a sumilar situation..
On a side note...never under estimate Erdogan and his party,they know how to tell the yanks to jogg off
