===Operation===

The M68 ALIM uses an [[Wikipedia:Linear motor|asynchronous linear-induction motor]] to produce a bipolar magnetic field capable of launching a 25x130mm projectile at an incredible speed of just under Mach 40, or approximately 13.7km per second.{{Ref/Reuse|PH}}{{Ref/Note|The speed of the Gauss Cannon's projectile in-game is much slower than its canonical speed of Mach 40. This is probably because of design and engine limits as well as balancing issue. The projectile moves more quickly in ''Halo 3'' than in ''Halo 2''.}} The great velocity of the projectile is the key to the stopping power and performance of the Gauss cannon, giving it exceptional armor penetration at impressive ranges.
