The Evil Empire is very good at mass producing fighters. Each Starbase (including Mining Stations) of the Evil Empire has the ability to create several fighters each turn from the minerals (3 KT Tritanium and 2 KT Molybdenum).
Similar advantages are available for 1, 2, 3 or 4 fighters. They do not depend on each other, and may be combined in any way (including the 5 free starbase fighters base advantage) to build as many as 15 free fighters each turn.
