Ballistic refers to the fact that basic gravity laws define the trajectory (as opposed to a 'guided' missile which can expend energy with purpose i.e. perform 'active measures' to affect it's own trajectory).

There are plenty of 'ballistic', but still conventionally-armed missiles.

At least that's my understanding from hazy memory ...
