The Biden administration showed its support Wednesday for the potential sale of F-16 fighter jets to Turkey, a day after Ankara raised a veto of NATO membership for Finland and Sweden. Celeste Wallander, Assistant Secretary for Defense for International Security Affairs at Pentagon, said robust Turkish defense capabilities would strengthen NATO's defenses.

"These plans are in the works. And, they need to be worked through our contracting processes," she added. Turkey made a request in October to the United States to buy 40 Lockheed Martin-made F-16 fighters and nearly 80 modernization kits for its existing warplanes. Washington had not previously expressed any opinion on the sale aside from saying all weapons sales would have to go through the necessary legal process. In March, the State Department wrote a letter to some members of the U.S. Congress who had been against the sale, saying "appropriate" U.S. defense trade ties with Turkey would serve U.S. interests.

The three nations signed a deal under which Ankara lifted its block on Finnish and Swedish membership, while the candidates pledged not to support the Kurdish militant PKK and YPG groups, or the network of U.S.-based cleric Fethullah Gulen, which Turkey blames for a failed 2016 coup attempt. U.S. officials pushed back against any suggestion that Washington was backing the warplane request to remove Turkish objections to the entry of Sweden and Finland into NATO. "The U.S. did not offer anything to Turkey and was not asked for anything by Turkey" as part of its agreement with Finland and Sweden, a senior administration official said. The official said U.S. officials were engaged in prolonged technical talks about Turkey's request to acquire U.S. F-16 fighter jets. Congress would have the final say about any such sales. Turkish President Tayyip Erdogan is due to meet with President Joe Biden later on Wednesday. Erdogan, before departing for Madrid on Tuesday but after a phone call with Biden, criticized the United States over the F-16 sale, saying it was stalling Ankara.
