I don’t know if they still do this but during the Cold War, they would practice tossing nukes.

The plane flies low and fast, at the right time it climbs hard, belly up and at the top of the loop releases the bomb. While the plane continues its loop downward, the bomb continues in a ballistic trajectory. By the time it hits the target, the plane spends a minimum of time at altitude and a good distance from its target and can GTFO.
