UNSC Infinity

"This is the culmination of human achievement."

- Unknown UNSC Official

"We are the giants now."

- Captain Thomas Lasky

The UNSC Infinity (INF-101) is a vessel commissioned into the UNSC Navy following the end of the Human-Covenant war in 2553. Infinity was a starship technology demonstrator, using recovered technology found during the war against the Covenant Empire and from Forerunner facilities and installations. Infinity's on-board AI, Roland, oversees all activities on the ship.

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 Infinity a secret from some senior members of the UNSC 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 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 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. In 2553, Infinity would assist Arbiter Thel 'Vadam in putting down a revolt led by the Servants of Abiding Truth.

Requiem
Four years after the Human-Covenant war, Infinity was officially commissioned into the UNSC Navy. One of her first assignments was to locate the remaining Halo Installations so that the UNSC could study them and later decommission them. While moving the Composer from Installation 03 to Ivanoff Research Station, Infinity would receive a set of co-ordinates leading to Requiem.

While en-route, the ship receives a beacon from the. Upon arrival, Infinity informs FLEETCOM of the situation and attempts to contact the two survivors of the Dawn. The Didact then seizes control of the ship and Infinity crashes onto the interior surface of Requiem, where it was attacked by Promethean and Covenant Remnant forces.

Later on, Infinity was able to take off and, after taking out a gravity well, escaped the shield world. When the Ur-Didact attacked Earth, Infinity engaged Mantle's Approach. After six months, Infinity would return to Requiem and begin operations against the Covenant and Promethean forces present on the shield world. At some point Infinity was boarded by the Covenant and Prometheans. While the Covenant trapped Infinity with the Artifact using its slipspace as an anchor, Jul 'Mdama planned to send Requiem into the sun and Infinity along with it causing a supernova. Fireteam Crimson, Fireteam Majestic and Sarah Palmer were deployed to deactivate the artifacts anchoring Infinity to Requiem and proceeded to quickly escape after freeing Infinity just as Requiem fell into the sun.



Specifications
Infinity is approximately 5.6 kilometres (3.5 miles) from bow to stern, placing it as the largest UNSC vessel. 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. The hull and shielding have been shown to be immensely powerful, as demonstrated when it rammed a and destroyed it with next to no damage to itself. The engines are of Forerunner design.

Armament
Infinity's primary armament is four CR-03 Series-8 Magnetic Accelerator Cannon. Infinity boasts a significant missile network that can be implemented for ship-to-ship combat, anti-air defense and orbital gunfire support for Marine forces. Placed throughout the ship are 1,100 missile pods of three types: Archer, Rapier, and Howler, totaling the ship's missile payload at 25,900 missiles. Close-in defense against enemy missiles, fighters, and boarding craft is provided by the ship's M965 Fortress point defense system, a network of 830 70mm automatic cannons. It also has a number of Mark 2488 Magnetic Accelerator Cannons placed along the ship.

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. After the Human-Covenant war it was re-purposed as an expeditionary and exploratory ship. It is also the location of a SPARTAN-IV training site. Infinity's mission prior to the First Battle of Requiem was to locate the remaining Halo Rings and other Forerunner installations and establish bases on them to oversee their decommission.

Trivia

 * Marathon Infinity is a game created by Bungie, and the possible namesake of the ship.
 * At over 5 kilometers long, the UNSC Infinity is the largest ship in the fleet, rivalling a which is over 5 kilometers long from bow to stern.
 * Infinity also devotes an entire deck of the ship to the training of the SPARTAN-IVs.
 * The final design for Infinity was supplied by Ansel Hsiao, a 3D Artist who previously submitted artwork for the Star Wars guidebook The Essential Guide to Warfare.
 * As shown in the first Spartan Ops cinematic, Infinity is capable of launching a number of s from a launchbay on its underside.
 * This capability makes it similar to the and, both of which can also carry smaller warships into battle.
 * It is also later seen to be able to allow a UNSC Prowler to land in one of its hangar bays.
 * At the end of Halo 4: Forward Unto Dawn the UNSC Infinity can be seen escorted by 13 s, and 28 s right before entering Slipspace, making it a total of 41 ships escorting Infinity.
 * Infinity is equipped with what appears to be two bow mounted Energy projectors, in place of the traditional Magnetic Accelerator Cannon, that it uses to punch a hole in Mantle's Approach.
