Radar dome

The radar dome, as it's name suggests, was the primary structure responsible for providing radar feed in the Great World War II, used by both the Soviet Union and the Allied Forces. It's most striking feature was the giant dome that housed the radar antennae, set on a concrete foundation, in which all the electronic and computer equipment required to operate the radar was housed.

The dome was constructed so that it would continue to function even when severely damaged. The only requirement was that continuous power supply was present. Without it, the radar ceased to function. After the war, with the refinement of radar and communications technology, the equipment was integrated with the communications centers, which took over the role of radar uplink units.

As a note, in the ending stages of the war, as the Allies developed GPS satellite technology, their tech centers took over the role of the radar dome when the satellite was launched.
