Turkey’s pending procurement of a Russian surface to air missile system would jeopardize its status in NATO, and disrupt other aspects of US military relations with that country, the Department of Defense told Congress.

“The U.S. Government has made clear to the Turkish Government that purchasing the S-400 [surface to air missile system] would have unavoidable negative consequences for U.S.-Turkey bilateral relations, as well as Turkey’s role in NATO,” DoD said in an unclassified summary of a classified report to Congress.
