The American side is asking us to increase the total number of engines for 8 units. They want us to increase the annual supply by a certain amount, in particular, in the 2015 year it is planned that we will supply them with eight engines instead of 5.

RD-180 - liquid-type rocket engine with a closed cycle. It is equipped with two combustion chambers and two nozzles. In the process of RD-180, kerosene is used as a fuel, and liquefied oxygen is used as an oxidizer.
In the USA, Lockheed Martin has rights to use Russian RD-180 engines. Without the use of engines of this type can not do the program "Atlas". This program, in turn, is designed for the launching of US government and commercial satellites into orbit.
