It is official now - the Duma terminated the agreement with Ukraine that allowed Russia to get data from the Ukrainian radars in Mukachevo and Sevastopol. The move was formally initiated in July 2007. The Ukrainian radars are supposed to be replaced by the new radar in Armavir (although it is not yet ready).
The Space Forces, which operate the early-warning system, are planning to expand the network of early-warning radars - at least two radars of the Voronezh-DM type, now deployed in Lekhtusi and Armavir, are expected to be deployed in the Far East and the Urals. The space-based EKS system is also expected to be part of the prospective early-warning system.
UPDATE 02/12/08: President Putin signed the law on February 12, 2008.
