Beams may be used. A Launch Tube is required per two fighters but does not need power. Fighter Carriers are as vulnerable as systemship carriers with this option. This should only be used with the systemship method. Fighters do 1 points of damage.
Any hit destroys a fighter.
Normally a ship can only fire its Beam at one other target ship. A ship can be built with more than one Beam. This means a ship may select more than one target. There is nothing to stop the Beams combining fire. This rule simply makes it possible to defend against fighters at a slight cost.
