The UNSC Fenrir is a Marathon-class heavy cruiser variant under the commanded of Captain Adrian Maxwell and home to the 122nd Naval Special Warfare Division.

Description
Built in secret by ONI Section III, UNSC Fenrir is 50% long and heavier than a standard Marathon-class cruiser, and was almost five time more costly to build. She features a prototype armor, honeycombed internal bracing, and a heavy MAC gun. She is also home to the 122nd Naval Special Warfare Division.

History
Construction of the Fenrir began in 2540 under Project: THOR, and was an attempt to create a more lethal and survivable class of warship. Unfortunately, her design proved too costly to warrant further production, and the project was canceled before Fenrir was completed. Listed as scrapped by ONI, she was in fact completed in 2547, and launched under the command of Captain Adrian Maxwell.

Notable Design Features
MITHRIL Polarized Armor System (MPAS)
 * Utilizes electromagnetically charged armor plates to disrupt EM fields surrounding Covenant plasma torpedoes and reduce damage to hull.
 * Power requirement: Minimal - 2% for optimal field strength

Honeycombed Internal Bracing (HIB)
 * Originally used in the Halcyon-class heavy cruisers, this method of construction, although expensive, greatly increases a ship's structural integrity.

Heavy Magnetic Accelerator Cannon (HMAC)
 * Ammunition: 1,200-ton Ferric-tungsten slugs
 * Muzzle velocity: 200,000 kilometers per second
 * Rate of fire: 3 rounds per minute

Advanced Shaw-Fujikawa Translight Engine
 * Discovered on the planet Valkyrie, this Forerunner-designed engine was examined by ONI, and in 2552, installed on the Fenrir for tests. The results were surprising: the advanced engine allowed the Fenrir to make longer, faster, and more accurate Slipspace jumps than any ship in the fleets of the UNSC or the Covenant.  Due to the complexities of the engine, however, it will be decades before it can be successfully reverse engineered.

Current Status
Officially, she is listed as scrapped before completion. In reality, however, she acts as a home for the 122nd NAVSPECWAR division, operating under the command of ONI Section I. Her primary mission is locate Forerunner worlds and secure information and technologies to help fight the Covenant.
