WorldArmor 9 Planetary Shield
The WorldArmor 9 Planetary Shield was a common type of planetary shield system produced by MerrWeapons. It was a type of encasing shield, making it cheaper to produce and able to operate longer, but created a solid wall of energy which did not allow friendly ships and weapons fire to pass through except heavily-guarded firing slots or gaps. The generator required a crew of twenty-five to operate.[1]
