The value of contract to deliver Russian S-400 air defense missile systems to Turkey stands at $2.5 billion, the head of the state corporation Rostec, Sergei Chemezov, said.
"We plan to begin first deliveries in March 2020," Chemezov said in an interview with the Kommersant daily.
Rostec's head added that Turkey will become the first NATO member purchasing the advanced S-400 system.
According to the official, the finance ministries of Russia and Turkey have already completed negotiations on the issue. "The only thing left is to approve the final documents," TASS cited him as saying.
"I can say that they will pay 45% of the overall contract value as an advanced payment, and 55% will be a loan from Russia," Chemezov said.
