Fleet base
Each level lets you have one more fleet in flight at the same time – from exactly the planet 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: level 1 allows one fleet, level 2 two, and so on.
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. The cost doubles with every level – so focus your upgrades on the planets you really launch many fleets from at once.
Background
The fleet base is the top command center of all mobile units. From here all naval movements of the planet can be controlled. With every additional level of the base it is possible to command one more mobile fleet.
