The colloquially named "'''four-forty'''" is an artillery piece weapon used by the [[UNSC Armed Forces]]. It had been introduced recently as of [[2552#October|October 2552]]. [[SPARTAN-III Program|Spartan-III]] trainee [[Dante-G188]] mistook a powerful, distant explosion on [[Onyx]] for the testing of a four-forty, which he claimed is a "big one"; however, whether he was referring to size, explosive yield, or both is unclear.<ref>'''Halo: Ghosts of Onyx''', ''page 116''</ref>

{{Conjecture}}
Though ''Halo: Ghosts of Onyx'' references the weapon as a type of artillery, its name is never explained. It is possible that the name is shorthand for a 4.40" (~112mm) bore, which would be appropriate for a fairly small artillery piece; however, this would conflict with Dante's description of the weapon as a "big one" unless the explosive yield is greater than the round's size would suggest. Alternately, "four-forty" may simply be a model designation such as "M440". A less likely possibility is that the four-forty is a large-scale mortar weapon, similar to Nazi Germany's 380mm [[Wikipedia:Sturmtiger|Sturmtiger]] and 600mm [[Wikipedia:Karl-Gerät|Karl-Gerät]].
