Ion engines are sold almost anywhere there is an outfitter, though they are most commonly found in Syndicate worlds, since the Syndicate produces them. The largest of the ion engines can only be found on certain Syndicate planets.

Ion engines are the cheapest engines a pilot can buy. When compared to human plasma engines they produce less thrust per ton, but are considerably more energy efficient and produce less heat. Ion engines are also generally smaller than their plasma counterparts of the same size.

X1050 ion engines are a single engine outfit that combines thrust and steering. They are not immediately available when the game starts, only being sold at the same time as the Syndicate Barb is created, as these engines were specifically made for that fighter.
