Russia has deployed its modern over-the-horizon radar systems, called Podsolnukh (Sunflower), to the Far East as well as the Baltic Sea and the Caspian Sea, director-general of the system's manufacturer (the Scientific and Research Institute for Long-Distance Radio Communications) Kirill Makarov explained. This reported by Sputnik.
"We are creating surface wave radars, designed to detect vessels and aircraft. These are Podsolnukh radars. They have already been put into service, used in three areas: the Far East, the Caspian Sea, and the Baltic Sea", Makarov said.
The system's functional capabilities are classified, but according to the Research Institute, the radars control a surface and air over a 200-mile zone, and are able to detect vessels from 200-400 km (125-250 miles).
