== Directed energy cannons ==
The term cannon has also been applied to several types of directed energy weapons. These have ranged from smaller vehicle-mounted turrets () to starship-mounted weaponry. () A common feature in these directed energy cannons is that their emitter needs to be physically aimed at the target () where as directed energy weapon banks and arrays usually have a more omnidirectional firing arc and the direction of fire can be programmed without moving the actual weapon.
