Turkish newspaper Yeni Safak says Ankara may switch to buying the Russian Su-57 fifth-generation fighter jet if Washington decides to suspend the delivery of F-35.

According to Turkish media, Turkey would likely opt to purchase Russian Sukhoi Su-57 twin-engine warplanes in place of US F-35 single-engine stealth fighter jets if Washington suspends the delivery of the latter in response to Ankara’s sale of S-400 anti-aircraft missile systems from Russia.

Earlier this week, a US Senate committee passed a defense policy bill, which would effectively bar the delivery of F-35 fighter jets to the  North Atlantic Treaty Organization (NATO) partner Turkey.
