Fleet base
Each level lets you have one more fleet in flight at the same time – from exactly the planet or asteroid the base stands on.

Every fleet you send from a planet occupies a fleet slot there for as long as it's underway – whether attack, transport, espionage or save flight. The number of slots a planet has depends solely on its Fleet base. Asteroids have their own base and their own slots.
Raiders love lots of slots because they hit several targets at once and scout on the side. Pure miners get by with just a few. Costs rise quickly – so think about which planets you really launch many fleets from at once, and focus your upgrades there.
Background
Every great empire needs a fleet base so that it can station its fleets there. The more the fleet base is upgraded, the more fleets can be stationed there, which also means that more fleets can be sent out at once. It will take a great deal of materials to upgrade the fleet base, so don't be surprised when the costs increase.
