Spacefaring (5)

All worlds of tech levels 1-4 that are part of an empire and have recieved a designation will gradually increase to level 5 on their own. Level 5 worlds can build an autocannon constellation in addition to lower-level defenses. Importantly, spacefaring worlds can build spaceports, which significantly increase the distance that they can trade goods with other worlds. Many new designations become available at this level.
