Radar
Olenegorsk was the site of one of the first two early warning radars in the Soviet Union, the other being at Skrunda-1. The Dnestr-M radar ( NATO codename: "Hen House") was started in 1963 and completed in 1969, entering service in 1971. A Daugava radar (NATO codename:"Pechora") was later built next to it. This is a prototype Daryal receiver, a phased array receiver which worked with the Dnestr acting as a transmitter. The Daugava, which is still operational, was implemented in Olenegorsk to minimise interference caused by the Northern Lights.Voronezh
It is planned to replace the Dnestr-M/Daugava radars at Olenegorsk with the new generation of Russian early warning radar systems, theReferences
