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]
