The next generation of Alliance Battlecruiser and a follow on to the venerable workhorse of the Alliance fleet - the Vanguard-Class - the Alliance's newer Noble-Class Battlecruiser is a step up in every way over her predecessor and the second ship of the Evolve-series of warships.
Weighing in at 32 million tons, she is 70% more massive than the Vanguard-Class battlecruiser and measures a full 200 meters longer. This added mass reflects a number of improvements in the hull adopted from the Archangel-Class Superdreadnought.
Firstly, Noble benefits from vastly improved anti-frigate/destroyer capabilities, sporting the quad-turret 4-inch rapid fire turrets first used on the Archangel. These weapons raise Noble's total Anti-frigate armament from a paltry 24 guns as seen on the Vanguard to Noble's 48. These newer guns are also significantly larger, firing 4" high velocity shells opposed to the the 2.5" low velocity rounds of the Vanguard's secondary armaments.
Furthermore, Noble sports the numerous improvements first seen on Archangel. Its new PHALANX - HALO command, combat, communication, and control (C4) utilizes the new wide spectrum gravimetric/photonic sensor suits. Coupled with the new Casper wide-array point defense laser and Messenger fire control uplink system, counter-missile defenses have never been so efficient.
In addition to the weaponry improvements, Noble is the first ship to sport the new Counter-Torquing Gravity Impeller. First utilized on the Celestial-Class, this new impeller design is far more efficient over traditional torquing impeller designs and allow Vanguard to achieve the same top speed of Vanguard with the same size engineering spaces despite the increased mass.
Probably the biggest improvement for Noble, however, comes in the computation side. While too small to utilize the Magi-Series tri-core linked A.I. introduced on the Archangel, Noble uses a similar system designed for Cruiser weight ships - the Gemini dual core system. Like its trip linked larger brother - Gemini cross links and integrates two A.I. cores which allow for dynamic allocation of computational resources between cores (rather than the tradition of variable A.I. for major systems). This system allows Nobles systems to cross communicate - fine tuning operations across the entire hull in response to the changing atmosphere of the battlespace.
