The fuel depot is a building available in all versions of Deadlock.
Aircraft departing from a territory with a functioning fuel depot have an increased range of +1 territory per turn. Territories featuring depots have an identifiable icon when seen from the world map.
Fuel Depots are large tanks of Neutrionic Fuel. They feature a small runway that is just enough for military planes to land. All military aircraft can land there and refuel. Therefore, aircraft that end their movement within the range of these depots will not crash by lack of fuel.
