The first shipment of a Russian missile defense system has arrived in Turkey, the Turkish Defense Ministry said today, moving the country closer to possible U.S. sanctions and a new standoff with Washington.
A Defense Ministry statement said "the first group of equipment" of the S-400 air defense systems has reached the Murted Air Base near the capital, Ankara.
Defense Minister Hulusi Akar said three planes carrying the equipment landed at the airfield today, adding that the delivery would continue in the coming days.
The U.S. has strongly urged NATO member Turkey to pull back from the deal — reportedly costing more than $2 billion — warning the country that it will face economic sanctions under the Countering America's Adversaries Through Sanctions Act if it goes ahead with the purchase.
It has also said Turkey won't be allowed to participate in the program to produce high-tech F-35 fighter jets.
Although U.S. President Donald Trump expressed sympathy toward Turkey's decision to purchase the Russian system during a meeting with Turkish President Recep Tayyip Erdogan on the sidelines of a G-20 meeting in Japan, Washington has repeatedly said that the Russian system is incompatible with NATO systems and is a threat to the F-35.
Sanctions would mark a new low in the already-tense relations between Turkey and the U.S.
Last year, the United States imposed sanctions on Turkey over its detention of an American pastor, triggering a Turkish currency crisis.
The deal with Russia — the first such deal between Russia and a NATO member — has also raised concerns that Turkey is drifting closer to Moscow's sphere of influence.
The acting U.S. secretary of defense, Mark Esper, said Washington was aware that Turkey began taking delivery of a Russian-made system.
Esper, who is expected to be officially nominated next week to be defense secretary, told reporters at the Pentagon that the U.S. remains unwilling to allow Turkey to acquire the U.S. F-35 stealth fighter, as long as it has the S-400.
Esper said he planned to speak to his Turkish counterpart later in the day.
The prospect of a further rupture in Turkey's relations with Washington also raises a delicate issue rarely mentioned in public: the status of American nuclear weapons stored at Turkey's Incirlik air base.
Turkey has had a nuclear role in NATO for decades, but this new split is likely to cause some in Washington to question the wisdom of keeping those nuclear bombs at Incirlik. Locations of U.S. nuclear weapons abroad are not publicly acknowledged by the U.S. as a matter of policy.
Turkey has refused to bow to U.S. pressure, insisting that choosing which defense equipment to purchase is a matter of national sovereignty.
"We've always said regarding the S400s that it's an agreement that has been finalized and the process continues to progress," Turkish Foreign Minister Mevlut Cavusoglu told reporters.
"There's no problem and the process will continue in a healthy way going forward."
Soner Cagaptay, director of the Turkish Research Program at The Washington Institute, said Turkey's purchase of the Russian system marks a "tectonic" shift in Turkey's security and foreign policy.
"Unfortunately, it looks like not only will there be U.S. sanctions but also probably a Turkey-U.S. rupture," Cagaptay said.
"This is tectonic because a rift with the United States now — at a time when Turkish-EU ties are also under strain — which would also impact Turkish-NATO ties, would leave Turkey alone against Russia for the first time in nearly 180 years."
