Two Russian early-warning satellites apparently completed their operations sometime after August 2009. The satellites, Cosmos-2422 (launched on 21 Jul 2006, NORAD catalog number 29260), which was deployed on a highly-elliptical orbit, and geostationary Cosmos-2379 (24 Aug 2001, 26892) stopped performing station-keeping maneuvers and have since drifted off their stations. The satellites operated three and eight years respectively, the first number being slightly below the average, and the latter - significantly above the average.
This brings the number of Russia's early-warning satellites to three. Two 73D6 satellites of the US-KS system on highly-elliptical orbits are Cosmos-2430 (23 October 2007, 32268) and Cosmos-2446 (2 December 2008, 33447). The only remaining geostationary satellite, Cosmos-2440 (27 Jun 2008, 33108), is apparently a spacecraft of the 71Kh6 type, which was supposed to work as part of the US-KMO system.
The two HEO satellites are positioned to provide some coverage of the U.S. territory for about 12 hours during a day. Cosmos-2440 is currently deployed in the point of 80 degrees East over the Indian ocean, from which it can theoretically observe Russia, China, North Korea, Middle East, and most of Europe.
