Rocket Engine

Standard and typical rocket engine, also called chemical engine. Contrary to the name it is a distant descendant of XXI-century rocket engine. One that is thousand times more efficient and that requires much less fuel to propel objects.
The part about requiring fuel is its biggest disadvantage, since they still require much more fuel than other types of engines. It is still widely used by the Terran Federation mainly because it is too technologically backward to be able to use more efficient Ion-Plasma Drives.
