Gravitic Launcher
From Warhammer 40k - Lexicanum
A T'au warship opens fire with its Gravitic Launchers[2]
Gravitic Launchers are a powerful type of T'au starship weapon.[1]
Gravitic Launchers are even larger railguns and consist of a two-stage launch system. First, mass drivers provide the initial burst of speed to launch the missile before the ship's gravitational field is pulsed to force the missile out at a tremendous speed. The missiles are drone controlled, giving them exceptional directional control making them highly dangerous weapons.
