Some models can. Usually they need to be upgraded for atmospheric flight, but a lot of operations take place out in open space, so the upgrades aren't necessary. It's really just a matter of having thrusters that'll let you steer and evade in a gravity free situation.

...Which, uh. That's what we use them for, mostly. Fighting in space. Blowing each other up.
