UNSC Infinity

The UNSC Infinity (INF-101) was a vessel commissioned into the UNSC Navy following the end of the Human-Covenant war in 2553. The Infinity was a starship technology demonstrator, using recovered technology found during the war against the Covenant Empire and from Forerunner facilities and installations.

History
The UNSC Infinity is seen in the Halo 4 demo from E3 2012 drifting near Requiem with a UNSC Frigate escort alongside. It is then somehow attacked with an EMP causing the Infinity to crash. The ship crashed and landed on Requiem where the ship was attacked by Promethean ground forces.

Later on, the Infinity was able to take off and continue further operations on Requiem.

Construction
This starship was constructed in the Oort cloud on the outskirts of the Sol System. The Office of Naval Intelligence attempted to keep the ship's construction a secret by permanently stationing workers in the Oort cloud while maintaining a complete communications blackout.

However, due to the ship's massive construction costs, the Office of Naval Intelligence was unable to keep the Infinity a secret from some senior members of the Navy, like Rear Admiral Saeed Shafiq.

This ship is to receive upgrades, particularly slipspace navigation which was reverse engineered from the Forerunner technology retrieved from Shield World Trevelyan as well as modified communications allowing ships to communicate even in slipspace. These modifications delayed the Infinity from full deployment as it was still not complete and with the modifications it would take even longer. Andrew Del Rio was assigned as the captain of the Infinity. The rest of the crew consisted of several SPARTAN-IV personnel. They were assigned to her before the preliminary trials on the ship began. There are 17,000 of humanity's "brightest and best" on board.

Specifications
The Infinity is approximately 5.6 kilometers (3.5 miles) from bow to stern, placing it as the largest UNSC vessel. Technical specifications are yet unknown, and based upon the given image of the Infinity, it seems to look incomplete since some of the sections appear to be exposed. The Infinity was given "Every scrap of Forerunner technology that the UNSC picked apart during the war." It has a primary armament consisting of 4 Magnetic Accelerator Cannons.

Purpose
The original purpose of Infinity was to beat back the Covenant in the event that Earth was lost and humanity needed a last resort, however that was no longer applicable after the conclusion of the Human-Covenant war. After the war it was re-purposed as an expeditionary and exploratory ship. The Infinity participated in the rebellion during Sangheilios as ONI did not want the state of Vadam falling too quickly or to have the Arbiter winning too easily. It is also the location of a SPARTAN-IV training site.
