How many Ion Cannons were there in space by the time of Tiberium Wars? In the Nod campaign Operation Stiletto you could capture GDI buildings and use the Ion Cannon. If there was only one Ion Cannon like in the first game(I think), then it would be as if two factions would be in control of the same Ion Cannon in Operation Stiletto. Unless of course there were many Ion Cannons used in different theaters of war. Was it mentioned anywhere how many Ion Cannons there were altogether or is there just one in space?
