This building can produce any ground and air vehicle (provided with component availability and hangar's space limit). The roof can be opened to launch any air unit completed from it. Usually, it will produce Allied sanctioned vehicles (with limitation on tech building requirement). Each building has its own power supply, but this facility is only used as auxiliary support. Should the power be cut off, the internal supply then automatically switches its power resource to the most vital working area. This guarantees the production line, but with limited energy, smaller areas can be powered, resulting in less than desired production rates. The hangar originally had a front door.
