The Emperor-class Battleship is a slow and ponderous vessel that serves as one of the mainstay capital ships of the Imperial Navy. The Emperor-class dispenses with the normal armoured prow and instead carries a mass of sensor probes and forward turrets. The Emperor-class also may carry eight squadrons of Shark assault boats or other common Imperial Attack Craft, which serve as its primary offensive punch.
The Emperor-class is one of the oldest Imperial starship designs still in use, due to the discovery of the Emperor-class vessel called the Divine Right that was fused into a Space Hulk for some ten thousand years. Emperor-class battleships along with the Retribution-class battleships are known to have a huge golden monument relating to the Imperium atop its bridge. The Emperor-class' monument is a cloaked angel with a sword and shield.
The main armament of the Emperor-class is made up of its 8 squadrons of Shark Assault Boats or other common Imperial Navy Attack Craft. These are able to roam far from the Battleship and engage enemy capital ships that would otherwise be out of range of the Battleship's main batteries.
Void Shields on Imperial vessels (and enemy vessels for that matter), are larger and more powerful versions than those found on Titans and other war machines. A Void Shield is created by a single generator that creates a sphere of protective gravitic energy around the voidship that protects it from direct and indirect enemy fire. It prevents damage from energy weapons and actual critical structural damage occurring to the ship. Any vessel large enough to be built with a Void Shield generator thus has a shield but energy weapons overload the generators so once enough fire has been absorbed, the Void Shield collapses. The shield regenerates several solar minutes later assuming the voidship is not attacked again and that subsequent attacks do not damage the shield generator. Ordnance like torpedoes and the weapons payloads of aerospace fighters are not affected by the effects of Void Shields and can do direct damage to the warship unless engaged by its defensive turrets. The Emperor-class Battleship possesses four shield generators and thus generates four separate Void Shields.
Every Imperial voidship is equipped with a Plasma Drive for normal propulsion through the depths of realspace. Running up to a third of the warship's length, the aft section of the Emperor-class is a mass of drive tubes, engine compartments and nuclear fusion-based plasma reactors. Most Imperial Navy starships employ Warp-Drives to breach the barrier that separates realspace from the Immaterium and allow for interstellar travel. Damage to or misuse of this technology can result in the implosion of these drives and the creation of a volatile Warp rift.
