A bomb is a device designed to explode - often used in war. It may, or may not, also have a propulsion system, but quite often, any propulsion is provided apart from the bomb. For example, a bomb may just be dropped from an airplane.

Jet Propulsion Laboratory Display Information System was created in 1973.
A UAV (Unmanned Aerial Vehicle) propulsion system refers to the combination of components that power and control the movement of an unmanned aircraft. The propulsion system typically includes an engine or motor, a propeller or rotor, and a control system that regulates the speed and direction of the aircraft.
