The '''''Poseidon''-class light carrier''' is a [[warship]] in service with the [[UNSC Navy]] following the [[Human-Covenant War]].{{Ref/Reuse|Bulletin}}

==Design details====
===Design details===
The ''Poseidon''-class carrier is sleek, elongated, and somewhat cylindrical in general shape. Its structure comprises two main sections covered with white plating; in the fore section, the plating mostly covers the vessel's dorsal surface. This plating is absent on most of the underside of the ship and in a spar connecting the two main sections. A series of rectangular blue lights are arranged in the sections lacking the white plating.{{Ref/Level|Id=midnight|H4|Midnight}} 719 meters in length,{{Ref/Reuse|Enc22}}{{Ref/Reuse|Bulletin}} the ''Poseidon'' is exceeded in both size and tonnage by the ''[[Orion-class assault carrier|Orion]]'', ''[[Epoch-class heavy carrier|Epoch]]'', and ''[[Punic-class supercarrier|Punic]]'' carrier classes.{{Ref/Site|URL=https://www.halowaypoint.com/en-us/news/canon-fodder-in-the-loop|Site=Halo Waypoint|Page=Canon Fodder - In the Loop|D=30|M=06|Y=2021}}

What it loses in size and armament, the ''Poseidon'' makes up for with its ease of manufacture in the [[Human-Covenant War|war-ravaged]] shipyards over [[Mars]] and [[Jupiter]]. The ''Poseidon'' additionally only requires a small crew to operate, allowing it to be pressed into service in [[2553]] - only months after the end of the war.{{Ref/Reuse|Enc22}}

===Armament===
The ''Poseidon'' is unusual for a [[UNSC starship]] in that it does not have a primary [[Magnetic Accelerator Cannon]] weapon system; instead, the carrier's heaviest weaponry consists of two [[Mark 2551 Onager]] turrets and two [[Archer missile|M42 Archer missile]] pods. The carrier's weapons complement is instead more focused on defensive measures, boasting twenty [[M870 Rampart point defense gun]]s.{{Ref/Reuse|Enc22}}

===Propulsion===
The ''Poseidon''-class is propelled in transit by a single [[fusion drive]] located on the back of the ship.{{Ref/Reuse|H4}} On at least one vessel, {{UNSCShip|Milwaukee}}, superluminal travel is accomplished via installation of an advanced [[Shaw-Fujikawa Translight Engine]] (SFTE), utilising technology reverse-engineered from alien [[Covenant]] and/or [[Forerunner]] technology recovered during the [[Human-Covenant War]]. This installation allows the carrier to make long-ranged [[Slipstream space|slipspace transits]] extremely rapidly - fast enough to allow the removal of the ship's [[Cryo chamber|cryogenics bays]] entirely to be replaced with simple seating.{{Ref/Reuse|LoO}} It is unknown whether the ''Milwaukee''{{'}}s advanced SFTE is representative of the ''Poseidon''-class as a whole, due to the ship's specific repurposing as a passenger ferry.

==Operational history==
===Transport to Sarcophagus===
After the [[shield world]] of [[Sarcophagus]] was discovered and colonised, the {{UNSCShip|Milwaukee}} was repurposed to carry personnel, civilians and goods between [[Onyx]] and the colonies.{{Ref/Novel|Id=LoO|LoO|Chapter=6}}

===New Phoenix Incident===
Several ships of this class were part of [[Battle Group Dakota]] alongside a number of {{Class|Vindication|light battleship}}s and {{Class|Strident|heavy frigate}}s. These ships engaged the [[Forerunner]] vessel ''[[Mantle's Approach]]'' during the [[Ur-Didact|Didact]]'s [[New Phoenix Incident|attack on Earth]] on [[2557#July|July 25, 2557]].{{Ref/Reuse|midnight}}

==Production notes==
{{linkbox|gallery=yes}}
*Several ''Poseidon''-class light carriers appear in the background of the ''Halo 4'' level ''Midnight''; given their nature they are intended to be seen only from a considerable distance. However, exploiting a [[Midnight vacation|glitch]] allows the player to examine these vessels up close, along with a number of {{Class|Vindication|light battleship}}s and {{Class|Strident|heavy frigate}}s. Because these ships are intended to appear only as scenery, they are rendered as brushes rather than level geometry; as such, the player can fly the Broadsword through them without harm. By the same merit the ships' in-game models are not to scale with their canonical incarnations.{{Ref/Reuse|Bulletin}}
*The ''Poseidon''-class carrier and ''Vindication''-class battleship were to be featured in ''[[Halo 4: The Essential Visual Guide]]'' but were cut due to space constraints.{{Ref/Reuse|Bulletin}}
