EKS (Russian: Единая космическая система, tr. Edinaya Kosmicheskaya Sistema meaning Integrated Cosmos System [3]) Kupol (Russian: Купол meaning Dome [4]) is a developing [2] programme of Russian early warning satellites as a replacement for the US-KMO and US-K satellites of the Oko programme. [5]: 7  The satellites are designed to identify any possible future ballistic missile launches, from outer space, and complement early warning radars such as the Voronezh. This gives advance notice of a nuclear attack and would provide information to the A-135 missile defence system which protects Moscow, as well as other Russian missile defense and counterattack resources. Six satellites are planned to be initially orbited. [1] The first of these was launched on 17 November 2015 [2] and as of November 2022, all six of them are in service. [6]

Background

EKS has been designated to detect and track ballistic missiles launched towards Russia or its allies. [7] The systems have been designed as a replacement for the current system of early warning satellites called Oko, which had its first launch in 1972 [8]: 36  [9] and was described in 2005 as "hopelessly outdated". [10] Oko has two types of satellites: US-KMO are in geosynchronous orbits and have an infrared telescope to identify ballistic missile launches. [11] US-K are in Molniya orbits and are an earlier model with optical telescopes and infrared sensors. [12] The Oko system has two control centres with the main one being Serpukhov-15 outside Moscow. [8]: 40  [8]: 52 

Oko is part of the Main Centre for Missile Attack Warning [13] which is under the Space Command (KK) of the Russian Aerospace Defence Forces. [14]

In 2014, Kommersant published that the first satellite, of a type named Tundra, would be launched in 2014. According to that report they would operate on highly elliptical orbits. The satellite was not launched in 2014, however. [15] It was eventually launched from the Plesetsk Cosmodrome on 17 November 2015, using a Soyuz 2.1b rocket with a Fregat stage, under the name EKS-1 / Tundra-11L. [2] [16] ( GRAU designation: 14F142 [17]) In November 2022, the sixth satellite was orbited. [1] [6]

Timeline

Information on the new EKS system is scarce but it appears that it was designed by Energia Corp in 1999-2000 and was selected against a proposal from Oko manufacturer NPO Lavochkin. [18] The Russian Ministry of Defence awarded the contract to Energia in 2007 with an expected delivery date of 2008, for a test launch in 2009. [19] In 2009, it was reported to be delayed until late 2011/early 2012. [20] In 2011, the Russian MoD sued Energia for the delay, claiming that a contract extension issued until May 2010 was invalid and asking for 262 million rubles in compensation. [21] According to news reports Energia said that the contract extension was valid and that the problem was with their subcontractors. [21] In addition, they said that the Russian MoD kept changing the specification and demanding things that were beyond the capabilities of the industry. [21] The Russian MoD lost the court case. Energia delivered a satellite in 2009 but as of April 2012 there had not been a test launch. [19]

In April 2012, the minister Alexander Sukhorukov announced that a contract had been signed to manufacture these satellites and that there would be a launch later in 2012. [22] The last satellites of the previous Oko system were Kosmos 2479, [23] launched on 30 March 2012, and Kosmos 2469, launched on 30 September 2010. [24]

The first EKS satellite ( Kosmos 2510, EKS-1, Tundra 11L) was eventually launched from Plesetsk on 17 November 2015 using a Soyuz-2.1b rocket [2] and as of May 2020 there were four in service which is the minimum standard strength. [25] [26] A fifth one was launched in November 2021 to start the expansion of the system capabilities. In November 2022, the initial constellation of six satellites was completed. [6]
