Fleet Beacon (Legacy of the Void)
- This article covers the current multiplayer version of this building. For another version see Fleet Beacon (Wings of Liberty and Heart of the Swarm).
The Fleet Beacon is a structure on the Protoss Technology Tree that unlocks capital ship level air units, specifically the Carrier and the Tempest at the Stargate and allows the Mothership Core to be transformed into a full Mothership. The Fleet Beacon also contains two ability upgrades for the Protoss fleet: the Phoenix's Anion Pulse-Crystals upgrade, which increases the attack range of the Phoenix, and the Carrier's Graviton Catapult upgrade, which increases the speed with which Carriers release Interceptors. Finally, the Fleet Beacon allows the Level 2 and Level 3 Air Weapons and Air Armor upgrades to be researched at the Cybernetics Core. The Fleet Beacon requires a Stargate before it can be warped in.
Like most Protoss structures, the Fleet Beacon can only be warped in at a location powered by the Psionic Matrix. It can only perform research while it remains within the Matrix, otherwise it becomes unpowered and cannot function. However, even an unpowered Fleet Beacon still unlocks all the same units and upgrades as a powered Fleet Beacon.
