UNSC Infinity

The UNSC Infinity is an experimental vessel commissioned into the UNSC Navy following the end of the Human-Covenant War in 2553.

Construction
The Infinity is a starship technology demonstrator, using advanced technology recovered during the Human-Covenant War from both Covenant and Forerunner sources.

The ship was constructed in the Oort cloud beyond the Sol system. Secrecy was ensured by having workers permanently stationed there over several years, with a total communications blackout in effect. The ship's massive cost, however, prevented the Office of Naval Intelligence from keeping the Infinity a complete secret; senior members of the Navy, such as Rear Admiral Saeed Shafiq, are fully aware of the ship's existence.

As of March 2553, technology from the recently discovered Sharpened Shield was planned to be incorporated into the ship. Refinements in slipspace navigation, in particular, were expected to push the construction process ahead of schedule. Andrew Del Rio was chosen to be the ship's commanding officer, and several SPARTAN-IV personnel were also assigned to the Infinity before the first trials began. The ship had a sizable contingent of SPARTAN-IVs after its launch as well.

At around 3.5 kilometers in length, the Infinity is the largest UNSC ship ever built. The ship also contains a state-of-the art combat deck, a training chamber that is capable of replicating environments.

Production notes
The Infinity plays a major role in Halo 4, serving as the fictional backdrop for the game's competitive multiplayer and Spartan Ops modes. The multiplayer component is grouped together into a game mode known as Infinity, in which players take control of SPARTAN-IV supersoldiers serving aboard the warship. In competitive multiplayer, player-controlled Spartans train against one another in the ship's environment-replicating combat deck, whereas Spartan Ops is a cooperative campaign mode which tasks players with weekly, episodic missions over the course of the Infinity's travels.
