Stonehenge
From Ace Combat Wiki
Stonehenge was an Erusian superweapon, used to shoot down the Ulysses 1994 XF-04 asteroids. However, when war came, it was used as an offensive weapon. It would destroy any aircraft above 200 feet. Eventually it was destroyed by Mobius 1 in the mission Stonehenge Offensive.
Appearance
Stonehenge was circular, about half a mile around. Perched in the desert, it had several cannons and SAMs all around it, along with a jammer pod in the centre.
