Human-Covenant War

 

The colloquially named "four-forty" is an artillery piece weapon used by the United Nations Space Command armed forces. It had been introduced recently as of October 2552. 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.[1]

Type[edit]

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 cannon or mortar, similar to Nazi Germany's 380mm Sturmtiger and 600mm Karl-Gerät. If so, the nickname might denote a calibre of 440mm, comparable to a large naval cannon.
