Stonehenge was an Erusian weapon, used to shoot down asteroids. However, when war came, it was used as an offensive weapon. It would destroy any aircraft not at 200 feet. Eventually it was destroyed by Mobius 1.

Stonehenge was circular, about half a mile around. Perched in the desert, it had several cannons and SAMs all around it.
