Four landing pads allow VTOL aircraft to be rearmed and refuelled. If desired the pads can become enclosed hangers. Like the war factory the airfield uses aerial repair drones. The drones repair not only landed aircraft but also those in a holding pattern nearby. Aircraft draw critical support from their base airfields even when in flight. Without a data link to the parent airfield, ion particle activity could prevent extended operations or result in guidance failures. In other words GDI aircraft will run out of fuel and crash unless they have not expended their payload.
