The Radar tower provides early warning of enemy units and their movements over a moderate distance at virtually no cost. It has a very small but steady energy cost and will automatically shut down if you run out of energy. Radar coverage is blocked by terrain such as mountains. Some units may carry a radar jammer or be able to cloak and evade detection by radar.
The Radar tower can also be morphed into a light scout plane, the Sparrow, mainly used for early game scouting when the Airplane factory is not available.
