U.S. Acting Defense Secretary Patrick Shanahan said Tuesday he will discuss Washington’s spat with Ankara over its purchase of Russia’s S-400 missile defense system with his Turkish counterpart Hulusi Akar, ONA reports quoting Anadolu Agency.
Asked if he had received any response from Akar on the issue, he said the two sides could update each other on developments during Wednesday’s phone call.
"I'm hoping tomorrow for he and I to exchange views and get an update on what kind of progress we've made. That's really all I have to update you on," he told reporters.
His remarks came ahead of his meeting with Polish Defense Minister Mariusz Blaszczak at the Pentagon.
Shanahan said last week in a letter to Akar that the F-35 fighter jet training program for Turkish pilots would end July 31, giving the pilots enough time to complete their training. However, this action will cut things short.
"We've suspended some of the activities in terms of training. We haven't suspended any of the maintenance activity," he added.
But the Pentagon said Tuesday that the U.S. Air Force has halted ongoing training of Turkish pilots on the F-35 before the end date for "safety" concerns.
The actions are the latest in a series of moves by the U.S. to try to remove Turkey from the F-35 program amid a standoff with its NATO ally over the purchase of Russian S-400 system.
Following protracted efforts to purchase an air defense system from the U.S. with no success, Ankara decided in 2017 to purchase Russia’s system.
U.S. officials argued it would be incompatible with NATO systems and expose the F-35 to possible Russian subterfuge, but Turkey has emphasized that the S-400 would not be integrated into NATO operability and would not pose a threat to the alliance.
Ankara said it was Washington's initial refusal to sell its Patriot missile system that led it to seek other offers, adding Russia offered a better deal that included technology transfers.
