"Humanity is no longer on the defense… we are the giants now."

- Thomas Lasky

The Infinity-class warship is a United Nations Space Command heavy warship class designed by the Office of Naval Intelligence during the Human-Covenant war as a massive assault platform capable of delivering enormous numbers of infantry and armor and carrying some of the heaviest firepower in the galaxy, should Earth fall. The first model, the was completed in early 2553.

Description
The Infinity-class warship is the largest spacecraft ever created by humanity. It has deployment bays from which smaller spacecraft can be deployed. In addition to almost five meters of Titanium-A3 armor, Infinity-class warships also boast incredibly strong energy shields reverse-engineered from Forerunner artifacts found on Shield World Trevelyan. The warships boast several Magnetic Accelerator Cannons, hundreds of 70mm point-defense guns, thousands of missile pods and experimental Forerunner artillery. Each vessel has at least 895 decks, with the most prominent ones being S-deck and the combat deck. S-deck functions as a massive barracks and armory for SPARTAN-IV operatives and the combat deck is home to a state-of-the-art training simulation deck, designated War Games.

Use
It is unknown when the concept of an Infinity-class ship was initially developed, but at some point prior to 2552, UNSC and ONI construction crews were permanently assigned to the Oort Cloud to begin construction of the first model, the. In 2553 Engineers from Trevelyan began assisting in the construction of the vessel, allowing Forerunner shielding to be equipped. The vessel's first deployment was to Sanghelios, where it crushed the forces of the dissident Sangheili monk, Avu Med 'Telcam. After this the ship was completed it was re-purposed as a peacetime vessel, searching for Forerunner installations. It was during this mission in 2557 that the ship took part in the First Battle of Requiem. The same vessel would return for the Second Battle of Requiem.

Trivia

 * The Infinity-class warship was originally designed by Catherine Elizabeth Halsey, as stated by herself in Spartan Ops: "I'm not walking around on the ship I built with my hands cuffed".
 * According to an Easter Egg located in the Halo 4 level Infinity, it has a 'sub-vessel deployment bay'. This is likely a reference to the new Strident-class Heavy Frigate it carries, or it could mean that it has vessels designed for submarine purposes.
