Duga-1 and Duga-2 ( - "duga" means "arc") were Soviet over-the-horizon radar (OTH) systems. They were developed for the Soviet ABM early-warning network. Both of these radar systems were aimed east and were fairly high power. They were predecessors of the Duga-3 or "Steel Yard" OTH system, which operated from 1976 to 1989. Duga-1 was the first experimental system. It was built outside Mykolaiv in the Ukraine, and successfully detected rocket launches from Baikonur Cosmodrome, about 2,500 kilometers away. The second prototype, Duga-2, was built on the same site. Duga-2 is able to track launches from the Far East, and from submarines in the Pacific Ocean, as the missiles flies towards Novaya Zemlya in the Arctic Ocean. This huge radar complex was restored recently (2002) after a fire which seriously damaged it. ==References==
