"The launch will be conducted at 14.00 Moscow time (10:00 a.m. GMT) to expand the orbital group of Russia's military satellites," a source at the Federal Space Agency said.
Russia is reportedly operating a network of about 60-70 military reconnaissance satellites.
Zenith-M is a modified version of the Zenith-3SL delivery vehicle used to launch spacecraft from the Sea Launch consortium's floating launch platform in the Pacific Ocean.
The new Zenith rocket has only two stages, while the Zenith-3SL uses an additional booster.
Meanwhile, Russia said Thursday it had successfully put into orbit a U.S. Genesis-2 commercial satellite using a modified version of an RS-20 Voyevoda (SS-18 Satan) intercontinental ballistic missile under the Russian-Ukrainian Dnepr spacecraft launch program.
