The Russian military is buying up jamming devices which it plans to mount on cell phone towers. The idea behind it is simple — the Kremlin could switch on the jammers, known as Pole-21s, during a conflict and pray a U.S. missile blitzkrieg becomes a bit less accurate.
“At the present time, the tests of the item have been completed and the system has been accepted into the inventory,” a Russian Defense Ministry spokesman told the Izvestiya newspaper.
Izvestiya noted the system “is integrated with the transmission and reception antennas that are installed on cellular communications towers, which are merged into a single network, which covers entire regions like a dome that is impenetrable for satellite navigation signals.”
Russia mounting jammers on cell towers is unusual, but the underlying military logic is reasonable. As it stands, the United States possesses a large disparity in cruise missiles, drones and guidance systems, such as GPS. Russia has its own satellite navigation system known as GLONASS.
