The United States Department of State has once again warned Turkey against purchase of Russian S-400 anti-ballistic missile defense systems, saying such an action would be against their “policy.”
“It goes against our policy to have a NATO ally such as Turkey use an S-400 system. Part of the problem with that, it is—that it is not interoperable with other NATO systems. And so we are against the—having some of our partners and allies around the world potentially purchase S-400s,” U.S. State Department’s spokesperson Heather Nauert said during a press meeting on Aug. 23.
Nauert was asked if Turkey’s move would “trigger” sanctions pursuant to the “Countering America’s Adversaries Through Sanctions Act” (CAATSA).
“I am not going to get into that. But we have made very clear what could trigger sanctions for other countries and entities around the world,” she said.
The U.S. State Department’s comments came after Russian state arms exporter Rosoboronexport announced the S-400 air defense systems would be delivered to Turkey in 2019.
Ankara’s decision to purchase a Russian sophisticated system has long been an issue between Turkey and its allies, particularly with the United States.
Military experts are concerned that the deployment of S-400s would put the security of allied weapon systems, particularly F-35 aircrafts and radar facilities into danger.
