Fuel is the amount of deuterium that each ship uses to get from A to B. Every ship on a fleet uses deuterium as fuel, and so, before departing, it is calculated based on the distance and base fuel consumption of each ship. The total consumption is given by where Fbase is the fuel consumption of each ship (see table on next section), distance is defined in this page and speed is the percentage of flight time the ship will be moving (chosen by the player on the fleet screen). Because deuterium fills space, the fuel must be stored on cargo, decreasing the total Cargo capacity of the fleet.
