Ships may also become undetected by landing on a world or passing through an asteroid hex. Planets have no detection capability at all. Allied neutrals, liberated Bongo province worlds and conquered worlds may produce transports, packets, corvettes, and frigates. If Fang is present on a world he controls, he may use his scientific knowledge to produce Dreadnaughts at a cost of fifteen points. Points may be transferred freely between friendly worlds.
Earth has especially primitive technology.
It has no production capability, and cannot refuel ships unless they end their turn on its surface. Earth has planetary defenses, but they are not activated until Bongo comes within one hex of the mother planet. The Flying Planet Fang's enormous power and scientific knowledge allow him to move the imperial capitol world, Bongo, about the universe. Bongo moves like a ship. It has an effectively unlimited power supply, but can only change course once every four turns.
