According to a report in Kommersant, Russia will launch a new-generation early-warning satellite, codenamed Tundra and identified as 14F142, by the end of 2014. The launch will begin deployment of a new system, EKS (Edinaya Kosmicheskaya Systema, Integrated Space System), which will provide early-warning as well as some other functions (probably space surveillance or, as some suggested, secure communication). Kommersant reports that the satellite will be delivered into orbit by a Soyuz-2.1b launcher with a Fregat booster stage. According to the report, the new system will have true look-down capability and will detect missiles launches originated from the sea as well as from the U.S. territory. Tundra will be deployed on a highly-elliptical orbit, but earlier reports suggested that the complete system could include geostationary satellites as well.

The flight tests of the EKS system were expected to begin in 2009, but it then slipped to 2011-2012. Now it looks like the system is finally ready for initial deployment.

EKS will replace satellites of the old US-KS and US-KMO systems - as of June 2014 only two 73D6 spacecraft of the US-KS (Oko) system, deployed on highly-elliptical orbits, were operational. The last 71Kh6 geostationary satellite of the US-KMO system was lost in March-April 2014.
