Turkey wants a return for its investment in the F-35 program and that talks on the issue are ongoing Te US removed Turkey from the program in 2019 after it acquired Russian S-400 missile defense systems ISTANBUL: President Tayyip Erdogan said on Sunday that the United States had proposed the sale of F-16 fighter jets to Turkey in return for its investment in the F-35 program, from which Ankara was removed after purchasing missile defense systems from Russia. Reuters reported earlier this month that Turkey made a request to the United States to buy 40 Lockheed Martin-made F-16 fighter jets and nearly 80 modernization kits for its existing warplanes. Speaking to reporters before departing for a trip to West Africa, Erdogan said Turkey wants a return for its investment in the F-35 program and that talks on the issue are ongoing. “There is the payment of $1.4 billion we have made for the F-35s and the US had such a proposal in return for these payments,” Erdogan said. “And regarding this, we said let’s take whatever steps are needed to be taken to meet the defense needs of our country,” he said, adding that the new F-16 jets would help develop its fleet. Ankara had ordered more than 100 F-35 jets, made by Lockheed Martin Corp, but the US removed Turkey from the program in 2019 after it acquired Russian S-400 missile defense systems. The decades-old partnership between the NATO allies has gone through unprecedented tumult in the past five years over disagreements on Syria policy, Ankara’s closer ties with Moscow, its naval ambitions in the eastern Mediterranean, US charges against a state-owned Turkish bank and erosion of rights and freedoms in Turkey. Ankara’s purchase of the S-400s has also triggered US sanctions. In December 2020, Washington blacklisted Turkey’s Defense Industry Directorate, its chief, Ismail Demir, and three other employees. Since then the US has repeatedly warned Turkey against buying further Russian weaponry. But Erdogan has indicated Ankara still intends to buy a second batch of S-400s from Russia, a move that could deepen the rift with Washington. The request for the jets will likely have a difficult time getting approval from the US Congress, where sentiment toward Turkey has soured deeply over recent years. There is bipartisan support in US Congress to push the Biden administration to put further pressure on Ankara, primarily over its purchase of Russian weapons and its human rights track record. Ankara has said it hopes for better ties under US President Joe Biden.
