The U.S. is considering Turkey’s request for the purchase of F-16 fighter jets, AFP reports, citing a U.S. official.

On October 17, President of Turkey Recep Tayyip Erdogan declared that Ankara would like to purchase cheaper F-16 fighter jets, allocating $1,400,000,000 for the cancelled F-35 deal. However, the U.S. states that the problem with F-35 may be the same problem for any order of an F-16 due to Turkey’s purchase of S-400 missile systems from Russia.

Representatives of the US Department of Defense on Wednesday met with Turkish officials in Ankara to solve the problems with F-35, while Secretary of Defense Lloyd Austin on Thursday held talks with his Turkish counterpart Hulusi Akar and stated that the Pentagon acknowledges the needs for modernization of Turkey’s military. The request for F-16 might be discussed during the meeting of U.S. President Joe Biden and Erdogan on the sidelines of the United Nations Climate Conference in Glasgow.

Talking about the idea of F-16, Erdogan hinted that Turkey can ask Russia for the fighter jets, if the U.S. rejects the request, but it’s not clear whether this will have an impact on Washington or not.
