Can't you fire a gun in each slot at the same time?

Can't Gunstar fire a gun in each slot at the same time. According to the query related public information, in the swarm game, each slot can be placed in a kind of weapon or tool, such as laser cannon, missile launcher and so on. When your fleet is in battle with an enemy, the weapon or tool on each slot can fire an attack, but not all of them can fire at the same time.
