The reactor is a terran add-on in StarCraft II. It lengthens the build queue by three slots and allows two units to be built simultaneously (this requires pushing the hotkey twice or selecting the unit icon twice, otherwise only one unit is built).

A structure may not be attached to both a reactor and a tech lab at once.


The reactor was developed during the research of protoss containment fields, which allowed terran commanders to double their production capacity.[1] Egon Stetmann, further researching these fields, was able to improve on the reactor design and combine it with the tech lab, creating the tech reactor.[2]

Cutting-edge Dominion Special Forces reactors rival the energy output of thor engines, with only marginally reduced reliability.[1]

Wings of Liberty CampaignEdit

In the StarCraft II: Wings of Liberty single-player campaign, access to reactor functionality for command centers and planetary fortresses is unlocked via 15 protoss research points and at the cost of automated refineries.[3]

Command centers and planetary fortresses can build two SCVs at the same time.[3]

We now have the ability to train two SCVs simultaneously, allowing our early mineral and vespene production to ramp up twice as quickly. This breakthrough, made possibly by recent insights into protoss containment fields, should help us get a stronger foothold early in future missions.

The following section contains information from a previous version of StarCraft II which is no longer valid.

The reactor was previously known as the nuclear reactor.[4] The main goal of its design was to have a visual distinction from the tech lab, so it was built to raise out of the ground and gain more height, while the tech lab is low and lengthens out.[5]

It could be salvaged in previous builds.[6][7]

Removes the structure and returns 75% of the structure's mineral and vespene gas cost. The process may not be aborted once started. A bunker cannot be salvaged while units are still in it.
