Though not as potent as the Fortress Colony tool in terms of firepower, Sector Capitals make up for it with economic power. The size of their colonies are tripled (though they retain their eight turrets) and they gain a space platform in orbit, unlocking an additional trade route. On the downside, two Sector Capitals must be positioned at least a hundred parsecs from each other before they can be constructed. Still, they give great benefits to nearby worlds.
