MMA Phalanx Shutter Shield

The Phalanx Shutter Shield is the most powerful planetary shield generator in the galaxy. It's power output, range, and efficiency are unmatched. The unit itself looks much like a sports stadium, ovoid and squat. For defense, the generator has limited shields, but the primary defense is the 5-meter thick layer of Class A ablative armor. The superdense material allows the generator to take a considerable pounding before being knocked out of action.

Shutter shield units are not "solid walls" like encasing shields, but are variable output, variable area capable. They can be overlapped to reinforce protection, and can randomly open various sections of the shield to allow ground-based weaponry to fire, to release starfighters strikes, capital ship sorties, or even blockade runners.
