Fuel

Most starfaring vehicles generate thrust and power either through fusion or matter/antimatter reactions. Fuels for these reactions often include the use of common fissile materials such as uranium or plutonium (whose fission reactions are used to provide the initial energetic kick required to start the fusion reaction) as well as fusible materials, usually deuterium, tritium and/or an advanced mixed-oxide material or more exotic substances, such as dragonium or trentadium.

Antimatter is created in specialized particle accelerators and requires the use of the same materials used for fusion reactions. A sufficient quantity of antimatter is capable of providing enough energy to provide a capital ship's FTL drive, and even a small quantity of antimatter could provide virtually unlimited fuel for a small craft.
