Russia's Space Forces last Friday launched a Soyuz-U carrier rocket with a Cosmos-series military satellite, a spokesman said. He said the rocket was launched from the Plesetsk space center in north Russia and successfully orbited a satellite that was assigned the serial number Cosmos 2455.

Some experts believe the Cosmos series with the identification of 2411 and upwards could be part of Russia's Oko (Eye) orbital missile early warning network. The Cosmos 2441 (launched on July 26, 2008) is believed to be the first in a new series of spy satellites (Persona), featuring updated imaging technology and an extended lifetime span of up to seven years. The Soyuz-U rocket is designed to orbit Soyuz and Progress manned and cargo spacecraft, as well as special-purpose satellites such as Cosmos, Resurs-F, Foton and Bion. The rocket has payload of up to 6,950 kilograms. A Soyuz-U was last launched from Plesetsk on April 29, 2009. Russia reportedly operates a network of 60 to 70 reconnaissance satellites and has carried out 16 space launches since the beginning of 2009. (Source: RIA Novosti).
