Its primary function is to let you warp in the mighty Protoss Carriers through your Stargates. However, the research options available through the Fleet Beacon are imperative. Your first course of action must be to develop Gravitic Thrusters for your Scouts, which give your fighter craft an invaluable speed enhancement. Of lesser importance are Apial Sensors, useful if you deploy Scouts as reconnaissance craft.

If you intend to construct Carriers, you would first be wise to have already established a sizeable fleet of Scouts to fly escort and defend your airspace in the interim. At that point, you absolutely must research the Increased Carrier Capacity option, without which Carriers are veritable flying trash heaps. You are advised to begin constructing Carriers as you research Increased Carrier Capacity because Carriers are very slow to build.

It simply cannot be stressed enough just how important it is to have firmly established a huge flow of revenue before purchasing a Fleet Beacon.
