Aerospace fighters are what we'd call a SSTO or Single Stage to Orbit craft, aka a space plane, that can also manouver etc and fight as a plane in space or atmo. But I was thinking (and with me that's always risky) would a ASF actually have enough thrust and fuel to get it into space? I don't think that if you launched a fighter from your typical terra type world that you'd have much in the way of endurance once you get out of space and into orbit, limiting their capabilities to near earth orbit and the like without risking running out of fuel and then becoming a bit of valuable salvage.
So if that's not a thing, would a ASF have some jettonable boosters that would be used to get it up and get it fast enough before its engine takes over and they then leave the atmosphere and get into space with something resembling a fuel supply? Or am I just thinking too much into this?
