Any object that exits the atmosphere in a ballistic trajectory of any length greater than 0 is suborbital.

Both systems aim to intercept enemy missiles midway through their flight, at the high point of their ballistic trajectory.

Any rocket that will enter a stable, ballistic trajectory as it falls is not safe to use with tumble recovery.

Once the booster falls away, the warhead continues on an unpowered ballistic trajectory, much like an artillery shell or cannon ball.
From the en.wikipedia.org
It takes up a ballistic trajectory that will deliver a reentry vehicle containing a warhead to a target, and then releases a warhead on that trajectory.

Because the spacecraft is already on a ballistic trajectory to the moon, it should still be able to intersect the moon without using up any additional propellant.

More preferable from a strategic point of view is a nuclear weapon mounted onto a missile, which can use a ballistic trajectory to deliver the warhead over the horizon.

It is the speed above which an object will depart on a ballistic trajectory, i.e. in free-fall, and never fall back to the surface nor assume a closed orbit.

This is slightly different from tumble recovery, which relies on some system to destabilize the rocket to prevent it from entering a ballistic trajectory on its way back to earth.
