The Medium Mass Driver is the midrange Mass Driver developed by the Word of Blake. It fires a slug the size of a 60 ton 'Mech at its target. Due to the sheer size of the weapon, it can only be mounted in a WarShip or Space Station that masses at least 1,500,000 tons. This means only Battleships and Space Stations could mount the Medium Mass Driver. In addition, only one Mass Driver could be mounted on a WarShip.

Like all Mass Drivers, the Medium Mass Driver wasn't very accurate[7] and had a restricted firing arc.[8]
