According to the deputy minister of defense, the industry has delivered the first two satellites of the new-generation early-warning system known as EKS. The first launch of a new satellite is expected to take place in November-December 2015, very much as announced this summer.
The EKS system has been in the works for quite a while - the first report that mentioned the system appeared in 2007. The complete system is said to include 10 satellites, which are expected to be deployed by the end of 2018. However, given the history of delays, it is safe to assume that the deployment will take longer. The satellites have been referred to as Tundra.
At the moment, Russia has no functioning early-warning satellites in orbit. The last two satellites stopped working some time in the fall of 2014.
