U.S. should not sell F-35 jets to Turkey unless it drops Russian system -U.S. general
Turkish President Tayyip Erdogan has said it is committed to buying the Russian system, despite warnings from the U.S.-led alliance that the S-400s cannot be integrated into the NATO air defense system.
"My best military advice would be that we don't then follow through with the F-35, flying it or working with an ally that's working with Russian systems, particularly air defense systems, with what I would say is probably one of most advanced technological capabilities," U.S. Army General Curtis Scaparrotti, the head of U.S. forces in Europe, said during a Senate Armed Services Committee hearing. Scaparrotti is also the NATO Supreme Allied Commander Europe.
U.S. officials have said that if Turkey proceeds with the S-400 purchase, Washington will withdraw its offer to sell a $3.5 billion Raytheon
Last month, Turkish Foreign Minister Mevlut Cavusoglu said Ankara's purchase of Russia's S-400 missile defense system was a done deal.
