Two lawmakers are requesting that the State Department provide details on Turkey's recent reported use of Russian-made S-400 surface-to-air missile system against F-16 Fighting Falcon fighter jets, as well as Russia's ability to gather critical intelligence through it on U.S. and NATO allies.
Turkey has used the S-400 radars to track its own F-16s in the past–a move seen as hostile toward the U.S. and allies that operate the fourth-generation aircraft, according to a congressional source who spoke to Defense News in August. The action was one of many that spurred U.S. lawmakers to secretly block an undisclosed number of arms sales to Turkey over the last two years, Defense News reported.
The latest move adds to tensions between the U.S. and Turkey, the NATO ally, which serves as a pivotal location for American troops conducting operations in both the Middle East and Europe.
