The starport is an advanced terran structure, responsible for the construction and maintenance of all space-faring vehicles and starships. Along with featuring a number of landing pads, a control tower may be attached to coordinate the upgrading and construction of advanced vessels.
Starports can function both terrestrially and as space stations. At least some feature a flight school.
Protoss plasma shields have finally given us the ability to fit the tech lab and the reactor into a single structure add-on. This new add-on, known as the tech reactor, replaces the old tech lab and reactor add-ons, and allows us to train two of any unit type simultaneously.
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The following section contains information from a previous version of StarCraft II which is no longer valid.
In early builds of the game, the starport was capable of being upgraded into the star base, but the building was scrapped.
The development team wanted to revise the starport and some other terran structures from the first game, but there wasn't enough time for this. The starport underwent only by a couple art revisions, the second revision done to realize the structures properly in 3D with all the flight animations and moving parts the placeholder art lacked. These versions were done two or more years or more before Wings of Liberty shipped, and didn't get the benefit of a texture unification pass.
