The '''M370 autocannon''',{{Ref/Book|Id=enc22|Enc22|Page=148}} also known as the "Pelican Gun" or "Nose Gun",{{Ref/Book|Id=HE320|Enc11|Page=320}} is an anti-personnel/anti-vehicle weapon mounted below the nose of [[United Nations Space Command]] [[dropship]]s, including the [[D77-TC Pelican]] (and its variants) and the [[D102 Owl]].{{Ref/Book|Id=EVG|EVG|Page=135}}{{Ref/Book|Enc22|Page=150}}{{Ref/Reuse|SOR1}}{{Ref/Reuse|Denning}}

==Overview==
===Design details===
The weapon fires 70mm depleted uranium slugs and is sometimes twin-linked with another such weapon, doubling its firepower.{{Ref/Novel|GoO|Chapter=1|Quote=With a hurricane roar, a UNSC Pelican dropship rose over the treetops and its twin chain guns spat a cloud of depleted uranium slugs at the incoming missile, making it bloom into a flower of fire and smoke.}}

Although powerful, it is not very accurate, and troops must rely on its fully-automatic firing to make cover. In space, or other significant distances, the Pelican must rely on its speed and maneuverability for protection.{{Ref/Reuse|HE320}} The weapon seemingly replaced the [[M340 autocannon]] that was common prior to [[2525]].{{Ref/Novel|TFoR|Chapter=10|Quote=John sized up her armaments - dented and charred armor, a pair of old, out-of-date 40mm autocannons.}}

Pilots and gunners of [[D77-TC Pelican]]s equipped with M370s are able to use the [[Integrated Helmet and Display Sight System]] to allow them track targets with head movements and display weapon information on their [[heads-up display]].{{Ref/Reuse|tf3}}{{Ref/Book|Id=Sybex|Halo: Combat Evolved: Sybex Official Strategies & Secrets|Page=66|Quote=[The Pelican] is equipped with electronic systems hardened against EMP; heavy armor; a 70mm "chin gun" controlled by a gunner and an IHADSS (Integrated Helmet and Display Sight System)-essentially wherever the gunner looksm the chin gun follows)}} This allows for very short delays between spotting enemies and firing as the turret can rotate up to wherever the pilot is looking.{{Ref/Novel|Id=tf3|TF|Chapter=3|Quote=The chin gun—linked to his helmet sensors—followed the movement of Peterson's head.}}

==Production notes==
The Pelican's nose gun was originally intended to appear in ''[[Halo: Combat Evolved]]'', though was ultimately [[Cut Halo: Combat Evolved vehicles|cut from the game]] for final release. The weapon can be observed in the [[Halo E3 2000 trailer]] build of the game, at which time the nose gun could be fully-retracted into the vehicle. The weapon was later featured in the ''Halo'' novels such as ''[[Halo: The Flood|The Flood]]'',ef/Reuse|tf3}} and the ''[[Halo: Combat Evolved: Sybex Official Strategies & Secrets|Sybex Official Strategies & Secrets]]'' strategy guide.{{Ref/Reuse|Sybex}} In [[2023]], the chaingun-equipped Pelican was one of the many vehicles restored by the [[Digsite]] team for use in [[Modding|mods]] for ''Halo'' games.{{Ref/Twitter|Id=Shadow|game_fabricator|1413299559875235841|Marcus Lehto|Quote=Yes, at that time is was just called "c ground transport"|D=09|M=7|Y=2021}}{{Ref/Site|Id=DigsiteDeliveries|URL=https://www.halowaypoint.com/news/digsite-deliveries|Site=Halo Waypoint|Page=Digsite Deliveries|D=07|M=07|Y=2023}}

In ''Halo: The Flood'' (including both its original [[2003]] and [[2010]] editions), the weapon is referred to as a ''heavy rotary cannon'';{{Ref/Reuse|tf3}} this has since been retconned by all visual depictions of the weapon (both including the original cut ''Combat Evolved'' model and the look established in ''[[Halo: Reach]]'').

We're correcting it in the digital already, but the print editions will have to wait until next printing. It's supposed to be 70mm; it's the M370, and when we were changing from M370 to mm, the three got left.}}
