Taking into account the presence of US submarines nuclear submarines close to its borders, Russia may place additional elements of an early warning network, including a radar station, in its Arctic zone, Viktor Ozerov, chairman of the Federation Council's Committee on Defense and Security, told Sputnik.
"The early detection and warning system has already been built, but additional elements should be placed there, I think," Ozerov said.
According to him, the additional elements could include a radar, as well as ground-, air- and space target-tracking systems.
