The Dominator class was originally conceived as a planetary assault and fleet-support vessel built around the colossal energies of the graviometrically-driven Nova Cannon. The ship was designed to remain behind the main fleet line, using the Nova Cannon to bombard the enemy at extreme range. The majority of Dominators are constructed the Ultima Segmentum at Kar Duniash, and are relatively rare in the Segmentum Obscuras. However, after the impressive performance of the Dominator Hammer of Justice during the Gothic War, the Segmentum Battlefleets showed a renewed interest in the Dominator.
The Dominator is relatively rare in Battlefleet Calixis, with only one example, the Astrum Astrae remaining in service. In part, this is due to the relatively peaceful nature of the Calixis Sector; while at a planetary level it may seethe with cult activity and apostasy, there have been relatively few fleet-level actions for some three centuries. The prized Nova Cannon are therefore relegated to more turbulent sectors, or to one of the massive crusades grinding down heretical forces across the galaxy.
To construct a Dominator, start with the Lunar-class hull (shown below), and equip it with an Armored Prow Component and a Stygies-pattern Nova Cannon. Dominators typically mount macrobattery broadsides instead of lances, as the power is needed for the Nova Cannon.
