Carrier

Archon
The Archon was commissioned by the Imperial Navy to act as a personnel and fighter carrier. The order to create the ship came as part of a unilateral initative issued by Navy Command in the wake of Emperor Kor-Azor's assassination. Sporting the latest in fighter command interfacing technology and possessing characteristically strong defenses, the Archon is a powerful aid in any engagement.
Chimera
The Chimera's design is based upon the Kairiola, a vessel holding tremendous historical significance for the Caldari. Initially a water freighter, the Kairiola was refitted in the days of the Gallente-Caldari war to act as a fighter carrier during the orbital bombardment of Caldari Prime. It was most famously flown by the legendary Admiral Yakia Tovil-Toba directly into Gallente Prime's atmosphere, where it fragmented and struck several key locations on the planet. This event, where the good Admiral gave his life, marked the culmination of a week's concentrated campaign of distraction which enabled the Caldari to evacuate their people from their besieged home planet. Where the Chimera roams, the Caldari remember.
Nidhoggur
Essentially a pared-down version of its big brother the Hel, the Nidhoggur nonetheless displays the same austerity of vision evident in its sibling. Quite purposefully created for nothing less than all-out warfare, and quite comfortable with that fact, the Nidhoggur will no doubt find itself a mainstay on many a battlefield.
Thanatos
Sensing the need for a more moderately-priced version of the Nyx, Federation Navy authorities commissioned the design of the Thanatos. Designed to act primarily as a fighter carrier for small- to mid-scale engagements, its significant defensive capabilities and specially-fitted fighter bays make it ideal for its intended purpose.
