Taking the generally good experience with the Hydra class battleship, Khyron's tech priests were determined to fulfil the command of their lord and build a better Battleship to replace the losses after the schism of the fleet following the ascension. The Moloch began trials after over a hundred years under construction, because it was build at Sakormand, a renegade forge world Khyron's forces invaded after losing Dargomma to his former subordinate Breitarg. The Moloch is optimized for combat against enemy battleships, in stark contrast to the multi-purpose nature of the Hydra.  Strong plasma cannon batteries dot the sides, able to deliver more firepower than found on most battleships, but at shorter ranges. Long ranged dorsal laser lances provide firepower where the plasma cannons cannot reach, but alone they are unable to damage a battleship. The prow mounted torpedoes on the Hydra were replaced by fighter hangars, giving the Moloch the ability to strike at enemy vessels before they get into range.  The original speed of the Desolator, on which they are based, could be restored with daemonic aid.
