Dunay radar
Dunay radar (Russian: Дунай, tr. Dunay literally Danube; NATO: Cat House, Dog House) was a system of two Soviet radars used to detect American ballistic missiles fired at Moscow. They were part of the A-35 anti-ballistic missile system. One sector of one of the radars, the Dunay-3U ("Cat House") is still operational and is run by the Russian Space Forces as part of the Main Control Centre of Outer Space.
