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}}
The '''70mm chain gun''' is an anti-personnel/anti-vehicle weapon mounted below the nose of some [[D77-TC Pelican]] [[dropships]].<ref>'''Halo: The Flood''', ''page 39''</ref>


==Overview==
==Overview==
===Design details===
The gun is linked to the movements of the pilot's head, which allows for very short delays between spotting enemies and firing, the turret will rotate up to 120 degrees to wherever the pilot is looking. However, the turret can also be operated by a copilot, or manually by a gunner.
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to [[2525]].{{Ref/Novel|TFoR|Chapter=10|Quote=John sized up her armaments - dented and charred armor, a pair of old, out-of-date 40mm autocannons.}}
This weapon fires very large 70mm shells. The rate of fire is most likely lower than most UNSC automatic weapons, though the shells certainly have heavy stopping power.


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.}}
==Trivia==
 
*While the weapon is said to be a chain gun (single barrel, few moving parts) the older older 40mm chin-mounted turret was said to be a rotary cannon (multiple rotating barrels, one barrel firing, higher rate of fire). This change is likely to compensate for the increased size of the projectile fired and the decrease in carried ammunition.
==Production notes==
*Though never seen in game, it is possible that this armament is used on Marine Corps Pelicans, while [[UNSC Air Force]] Pelicans are seen sporting the same chin-mounted [[M638 Autocannon|M638 20mm cannon]] as the [[UH-144 Falcon|Falcon tiltrotors]].  
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]]'',{{Ref/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]]'').
