"The Nautilus Cannon is beast in naval combat, it can drop a shield within a few hits and can rip through any armour."

- Unknown UNSC Naval Crewman

The Weapon/Anti-Spacecraft Model 18 Nautilus Cannon (abbreviated as W/AS M18 NC), otherwise known as the Nautilus Cannon and quite often called Sphasers are a ship-mounted weaponry seen on UNSC Naval vessels. The Nautilus Cannon follows in the same footsteps of its smaller, less powerful Spartan Laser in design but has essentially been 'pumped up' to meet the requirements of naval combat. Unlike its man-carried cousin, the Nautilus runs on the power from the ships and therefore cannot run out until the ship runs out of deuterium fuel or the Nautilus suffers damaged from overuse.
