A grenade launcher was a weapon used to shoot grenades over longer distances than they could usually be thrown. Grenade launchers could also be mounted to starfighters, making it possible for some ships to fire concussion grenades. By adding these launchers, a starfighters overall effectiveness could be greatly raised. Some of the most common types of grenade launchers was the Thermal Detonator Launcher and the EMP Launcher. The Galactic Empire's Merr-Sonn Mobile Grenade Mortar was the vehicle form of a grenade launcher. The Grenade Mortor could fire up to one hundred grenades per second. The Empire also sometimes equipped grenade launchers on a Mobile Defense Unit.
