What limitations are there on fleet sizes and speeds?
Individual fleets have limited stack sizes – you can only add so many of certain types of vessel. Each fleet may have up to: 3 Flagships, 25 Cruiser/Destroyer, and 30 Fighters per type. Fleet speed is determined by the lowest rated hyperdrive fitted to any capital ship (Flagship, Destroyer or Cruiser) in the fleet. In order for hyperdrive upgrades to make any difference, the entire fleet needs to be upgraded. Fighters that travel with capital ships maintain the same speed as the ships they escort (I presume they are carried with the capital ships). Fighters in a fleet that contains no capital ships (i.e. just fighters) will travel far slower.
