"That MAC gun could put a hole clean through a Covenant capital ship. Coordinated fire from the Athens and the Malta, nothing's getting through this battle cluster in one piece."

— Avery J. Johnson

The Moncton-class orbital weapon platform (hull classification symbol: OWP) is a line of orbital defense platforms in the service of the United Nations Space Command. They have been a staple of the UNSC's planetary defence strategy for decades, seeing service in the Insurrection, the Human-Covenant War and post-war era.

Overview

Powerplant

The Moncton-class, unlike its cousin in the Erőd-class, was built with an on-board power source. As well as a fusion reactor, the lower stalk of the station was composed of stacked liquid-metal capacitors, which allowed for the rapid firing of its MAC so long as there is charge in their cells. If the reactor is damaged, the docking umbilicals could parasitically leach charge off a docked UNSC warship to power its weapon.

Armaments

Moncton-class platforms are equipped with a 14D4A1 Magnetic Accelerator Cannon, a power-hungry 802.2 meter (2,632 ft) long coilgun that fires a ferric-tungsten round traveling at several kilometers per second, which carries enough energy to punch clean through a Covenant capital ship. The shell is accelerated by hundreds of asynchronous linear induction motors, which all line the barrel of the weapon. They were also equipped with seven M606 Goalkeeper point defense guns to protect them from enemy fighters, bombers and boarding craft.
