The First Legion Navy
The Legion Navy of the year 4000 was technologically built upon the third iteration of Legion Trans-Newtonian (TN) technology in most respects, with the first iteration having fought the Trans-Newtonian War and the second iteration being largely restricted to prototypes and R&D work in the post-war period. The backbone of the Legion Navy at this time consisted of fast ion drive propulsion, robust and rapid-firing railgun batteries in multiple sizes, and ultra high-resolution uridium-based sensor technology powering targeting systems and fire controls in all Navy vessels.
The backbone of the Legion Navy was the Defiant-class Light Cruiser. Sporting an impressive array of 152 mm railgun batteries, while capable of modest point defense the real mission of a Defiant was to close with the enemy at speed and destroy them with bursted railgun fire, in true Legion style. While capable of this mission, Legion analysts complained that the class was based on too small a hull, and a future upgrade to perhaps 15,000 tons void displacement was a subject of active debate at Legion Navy headquarters.

Built on the same hull as the Defiants, the Grand Cross-class Light Jump Cruisers traded the entire armament for squadron jump capability. Thus, a squadron of three Defiants and a Grand Cross was in theory capable of prosecuting a campaign anywhere in the galaxy.

If the Defiant class was the backbone of the Legion Navy, the Charybdis-class Destroyers were its workhorses. Equipped with a seemingly-limitless arsenal of 102 mm rapid-firing defense batteries, the Charybdis class provided a formidable point defense capability to supplement the offensive firepower of the Defiant cruisers.

As with the cruisers, several ships of a modified design were built on the same hull to provide a jump capability. The Furious-class Jump Destroyers thus ensured that the Legion’s cruiser squadrons would have adequate supporting fire no matter where in the galaxy they were fought. Unlike the Grand Crosses, these retained a small number of point defense batteries to further support their comrades in arms.

As every powerful fleet body needs eyes and ears, the Bellerophon-class Frigates were also deployed by the Legion alongside the larger ships. Unarmed except for a small point defense battery, the primary mission of the Bellerophons was to provide long-range passive detection and active target acquisition capability for the larger warships. While some in the Legion Navy questioned the tactical value of long-range sensors for a fleet armed with short-range weapons, the Legion high command generally kept to the opinion that battlefield intel could never be had in excess.

As with the larger warships, a jump-capable warship was based on the same hull as the Bellerophons. The Excelsior-class Jump Frigates mounted a squadron jump drive in the volume freed by removing the Bellerophons’ sensor suite, ensuring a mobile sensor capability for the Legion’s war fleets, in addition to an extra defense battery over the Bellerophons.

Additionally, a third frigate design was based on the same hull. The Ars Magica-class Survey Frigates were actually the first iteration of this hull type to enter production, owing to the premium value placed on its capabilities by the Emperor himself. Equipped with a self-jump drive and a set of gravitic and geological survey sensors, the Ars Magicas had the crucial mission of finding new systems, resources, and most of all alien races for the Legion to conquer and exploit.
