A '''440mm''' (or "Four-Forty" as referred to by UNSC troops) is a [[UNSC]] [[weapon]] developed around [[2552]]. As an artillery piece, it is most likely used to destroy [[Covenant]] bases, or possibly to target [[vehicles]]. During a training mission on [[Onyx]], one of the [[SPARTAN-III]] candidates mistook an explosion caused by an [[Onyx Sentinel]] for a .440. It may be an explosive shell, or, more likely, an artillery rocket. It was recently introduced prior the the Battle of Onyx.

When contacted, even [[Eric Nylund]] could not explain such an oddity. [[Letter - RE:Four Forty Artillery|He mentioned]], however, that a 440mm cannon could be used against orbital installations.

{{Conjecturalization}}
The size discrepancy, being an apparently .440 round, poses a problem in terms of firepower. However, if the .440 artillery uses [[mass driver]] technology, like that of Harvest, then the size makes much more sense - the kinetic energy imparted by a railgun or coilgun means that the projectile does not need to be particularly large, or even explosive, to inflict tremendous damage upon a target. This is one of several theories, but remains conjecture for now.
