UNSC Infinity

The UNSC Infinity is an experimental warship of the UNSC Navy commissioned following the end of the Human-Covenant War. Built in secret using technology recovered from Forerunner and Covenant sources during the war, the Infinity is the UNSC's most advanced warship to date. Infinity serves under the command of the Office of Naval Intelligence and is captained by Andrew Del Rio, a seasoned naval officer.

Construction
The ship was constructed in the Oort cloud approximately one lightyear beyond the Sol system. Secrecy was ensured by having workers permanently stationed there over several years with total communications blackout in effect. The ship's massive building expenditures, however, prevented Naval Intelligence from keeping the Infinity a complete secret. Many senior members of the Admiralty, such as Navy Procurement commander Rear Admiral Saeed Shafiq, are fully aware of the ship's existence. Andrew Del Rio took command of the Infinity and her pre-commission crew years prior to the end of major hostilities in the war.

As of March 2553, technology discovered on Trevelyan, a Dyson sphere located in the Zeta Doradus system, was planned to be incorporated into the ship. Refinements in slipspace navigation, in particular, were expected to push the final construction milestones ahead of schedule. Unlike older warships that had only areas such as a gym or hangar space for Marines and Spartans to train in, the Infinity is the first known vessel to include a state-of-the-art virtual reality combat deck capable of replicating environments from across the galaxy.

At approximately 3.5 kilometers in length, the Infinity became the longest warship the UNSC Navy has commissioned into the Fleet, usurping the supercarriers and other vessels such as the war retrofitted Phoenix-class colony ships.

Trials
With the additional upgrades from Trevelyan, the first space trials of the Infinity were undertaken in mid-2553 with Del Rio at the helm. A number of SPARTAN-IV's, the newest generation of the highly famed augmented soldier program, were assigned to the Infinity before her maiden voyage; additional Spartans were included in the ship's contingent as time progressed.

Requiem
In the Summer 2557, Infinity picked up the distress call of the (FFG-201) and her two surviving crew, Master Chief Petty Officer John-117 and his Smart AI companion Cortana, now surviving on the Forerunner shield world Requiem. Her complement of Marines and Spartans would later assist the veteran Master Chief in combating the "ancient evil" that inhabits the complex artificial environment.

Production notes
This advanced ship plays a major role in Halo 4, serving as the fictional backdrop for War Games and Spartan Ops, the competitive multiplayer and episodic cooperative campaign modes in the appropriately named Infinity section. War Games, in which players take control of SPARTAN-IV supersoldiers serving aboard the warship, train against one another in the ship's environment-replicating combat deck. Spartan Ops puts up to four players in the shoes of Majestic Squad in a series of weekly episodic campaign missions following the ongoing story of the Infinity and her crew.

The upcoming feature-length film Halo 4: Forward Unto Dawn will chronicle the military career of an officer from the Infinity who will play a prominent role in Halo 4. On the April 17th, 2012 episode of the TBS late night comedy show Conan, hosts Conan O'Brien and Andy Richter announced that they'll be voicing Navy deckhands, whom the player will be able to interact with while they lift crates in the Infinity hangar bay. They can be encountered towards the end of the game.
