Etymology

The idiomatic usage derives from the second-generation of jet fighters, armed with guided missiles, in the late 1950s into the 1960s, with the informal military sense of fully-powered non-ballistic missiles going ballistic when losing control and assuming a free-fall trajectory, sense 3. But in subsequent usage the term has often become associated with the intentionally ballistic, suborbital trajectories of long-range, typically nuclear-armed missiles, sense 2.
