What distance can it travel on maximum speed?

Standard SCM flight on ships doesn't burn fuel in the sense we know today. With the technological advancements of 930 years, ships equipped with the proper intakes like the NOX can create and replenish the fuel necessary for everyday operation. In this way, you can travel at maximum SCM speed for extended periods of time. For afterburner speed, you will still have a limited amount of fuel as with any other ship.
