Presumably, at TL12+, you don't really *need* aircraft.

(At least where "aircraft" means "depends on aerodynamic lift and
control surfaces to operate in athmosphere.")

At some point, grav vehicles replace aerodynamic-lift vehicles for
aerospace control functions.

OTOH, aerodynamic control surfaces *may* allow tighter maneuvers than
a a 6g brick might otherwise manage.
