Bringing up the front of the formation is the Atmos class blockade cruiser. Designed to be a lumbering, invulnerable beast, it sports little weaponry beyond it's beamers. X-variants are being used as test platforms for a new gravity based weapons system.
Behind it, in the midst of the fleet, are the Hephestos class repair frigate. Designed to provide additional point defense and repair capability to a fleet, they also form a capable wolf pack in small numbers.
Pulling up the rear is the Viper class assault cruiser. Mounting modified beamers that weigh in at approximately 4 times their standard issue cousins. They are capable attack craft, though they are decidely fragile if misused in combat.
Finally, the pride of the fleet:
The Gjallerhorn class Flagship is currently one of a kind. Fielding a large arsenal of beams, drones, and a surprisingly formidable point defense system.
It's primary weapon is it's Ultrabeamer, which packs enough photonic annihilation to shred anything that it is set upon. Backed up by two standard beamers for overkill, and enough rapid fire scatterbeamers to cover most angles of attack.
It's modified drone bays launch 5 drones a piece and the weaponry on the aft section is primarily there as back up.
