Ships in a fleet engage together in combat. It is often beneficial to combine small fleets, as a group of ships is harder to eliminate at a single time. Often smaller fleets can easily be eliminated by fighting each of them in sequence.
There are several modules (Weapon, Defense, or Support) that boost the abilities of the the entire fleet, if present on any of the ships. More than one of these modules can be present, and the effects stack (add) together.
Movement orders are carried out by right clicking after selecting the fleet. A fleet must reach a system before it can act - it cannot stop a move order in the middle of a path. You will not get error messages if a fleet cannot move to a certain position because of a lack of technology.
All other orders - management orders such as merge, disband, as well as attack, blockade, and invade, may only be carried out on a system. Note that automatic combat from enemy blockades/interception will prevent you from ending your turn.
