Editing Airlock

{{ratings}}
'''Airlock''' is the name given for any area of a [[UNSC]] ship where one can leave the ship, such as the [[Bumblebee|lifepod]] or [[HEV]] launch area.

Technically, an airlock is a device which permits the passage of people and objects between a pressure vessel and its surroundings while minimizing the change of pressure in the vessel and loss of air from it. The lock consists of a small chamber with two airtight doors in series which do not open simultaneously. Also, some airlocks on ground prevent compression, such as underwater excursions akin to the space compressions.

An airlock may also be used for passage between environments of different gases rather than different pressures, to minimize or prevent the gases from mixing.

Airlocks are used in UNSC spacecraft to prevent pressure loss from exposure to vacuum either due to a hull breach or the deployment of a lifepod or HEV.<ref>[[Halo: The Flood]]</ref> [[Halcyon-class Cruiser]]s in particular employ them as redundancy features for survivability during combat with [[Covenant]] warships. The ''[[UNSC Hopeful]]'' also had an airlock large enough to cycle a fleet of dropships simultaneously.<ref>''[[Halo: Ghosts of Onyx]]''</ref>

Covenant airlocks feature a force field similar to Jackal Shield Gauntlets that have to be deactivated to allow anything through. It is impervious to any Human projectiles.

-An '''airlock''' is a device which allows passage between two areas of drastically different pressures and/or atmospheric composition, while preventing the exchange of gases and pressure. An airlock consists of a small chamber with two airtight doors in series, which do not open simultaneously. They are most commonly used on spacecraft, where they allow safe passage between the pressurized interior of the ship and the vacuum of space, though they can also be found in enclosed habitats on worlds with toxic atmospheres, for example.<ref>'''Halo: Fractures''', "A Necessary Truth"</ref>

-On [[United Nations Space Command|UNSC]] spacecraft, [[hangar bay]]s, [[Class-3 Enclosed Heavy Lifeboat|lifepod]] or [[drop pod]] launch areas are typically equipped with airlocks, used to prevent pressure loss from exposure to vacuum either due to a hull breach or the deployment of a lifepod or HEV.<ref>'''[[Halo: The Flood]]'''</ref> {{Class|Halcyon|cruiser}}s, in particular, employ them as redundancy features for survivability during combat with [[Covenant]] warships.

-The Covenant typically employs [[energy barrier]]s in place of physical airlocks. Certain UNSC facilities also employ energy barriers for this purpose, presumably having reverse-engineered Covenant or Forerunner versions.
