Overlord-class Battlecruiser

The Overlord-class Battlecruiser was based on the Acheron-class Heavy Cruiser in an effort to create a Cruiser-sized warship with the range and firepower of a Battleship. The Overlord was generally a success in this regard, despite many problems surrounding its design. Difficulties in replicating the Acheron class's power transmission systems led to the Oberon having an armored prow and forward Torpedo tubes in place of the Acheron's forward Weapons batteries. Fortunately, this had the side effect of freeing up enough power to allow the installation of an upgraded dorsal Lance turret and row upon row of long-ranged broadside Weapons batteries, resulting in the long-ranged firepower that the Oberon's designers had hoped for. Further difficulties in actually building the Oberon class, however, meant that each one must be painstakingly constructed at the Cypra Mundi shipyards, and as such very few are in service with Battlefleet Obscurus, with only three seeing action in the Gothic War.

Notable Overlord-class Battlecruisers

 * Cypra Probatii - The Cypra Probatii was completed partway through the Gothic War and arrived in the Gothic Sector only after a long and dangerous Warp journey from Cypra Mundi. It later had its point-defense turret array upgraded.
 * Righteous Power - The Righteous Power fought in the Taros Campaign. It scored the killing blow on the Or'es El'leath (Custodian)-class Battleship A'Rho.
 * Flame of Purity - Fought in the Gothic War alongside the Sword of Retribution.
