As part of the overhaul of the Ghost Program shortly after founding the Terran Dominion, Emperor Arcturus Mengsk ordered the construction of dedicated ghost academies with attached nuclear silos. However, these academies had an issue where radiation from the nuclear silos would leak into the nearby training areas. Newer designs fixed this issue.
All structures repair themselves to 50% life. All structure fires are automatically put out.
This all-in-one safety system automatically dispatches robotic drones to put out any fires and perform basic repairs on damaged structures. Although these drones are effective at doing basic repairs, they do not have a strong enough AI to perform the more delicate repairs needed to restore a structure past half life.
The ghost academy can be build by Nova in Co-op Missions. They research upgrades for Nova (ghost upgrades are researched at the tech lab) and allow her to train spec ops ghosts. Nova automatically begins every mission with a ghost academy, but if it is destroyed can build another as a normal structure. She is otherwise limited to a single academy at a time.
The ghost academy uses the former shadow ops render. It was capable of flying in early versions of the game, but this was later removed, as it was decided that only unit-producing structures should be capable of doing so. Such a technique unbalanced the ghost academy in multiplayer, as players could move it to an obscure corner of the map and nuke the enemy at will.
