That’s what computerized control systems are for. I’m sure that’s the idea
behind the Babylon 5 Starfuries. Remember, physics works a bit differently in a
vacuum than it does in a thick atmosphere. In an atmosphere you can use
steering fins to alter the course of the missile, but in a vacuum, thrust is the
only thing that matters. Changing direction with only a single point of thrust
is impossible in a vacuum, and the wider your thrust base is, the more efficient
it will be...as long as you didn’t cheap out on the control system.
