A Nova Cannon is a weapon of great size and destructive power used by ships of the Imperial Navy which propels explosive projectiles close to the speed of light.[1c]
Contents
Overview
While some variation exists, the basic design of a Nova Cannon consists of an array of gravimetric impellers which accelerate a projectile to a fraction of the speed of light.[2a] However, Nova Cannons can only be mounted on large capital ships such as Cruisers and Battleships and in the ship's prow.[2a] This is because the immense recoil of firing the weapon can only be compensated for by the vessel's engines.[1c] While at least one Astartes Battle Barge is known to have been retrofitted with a nova cannon, doing so taxed the vessel to its limits: firing the weapon resulted in momentary power failure throughout the ship.[7]
The projectile itself varies in greater design and size, ranging upwards of fifty meters in diameter.[3] However, all share the common goal of causing immense destruction across thousands of kilometers of space. These can range from sophisticated plasma warheads which burn with the ferocity of a small star for a fraction of a second to implosion devices which exert destructive gravitational forces.[2a]
Because of the destruction it can cause over a vast area, a Nova Cannon projectile is not armed until a fraction of a second after firing, though by that time it will have already traveled tens of thousands of kilometers through space.[2a] For those captains which do mount them, a well-used Nova Cannon can be a terrifying weapon and psychological tool.[2a]
Although typically found on starships, there is at least one known ground-based Nova Cannon. It is found mounted on the legendary Ordinatus engine known as Oberon - the Ordinatus Armageddon.[8]
Models
Mars-pattern Nova Cannon
The Mars-pattern Nova Cannon is the most common of all Nova Cannon construction templates. Colossal weapons measuring hundreds of meters in length, they fire a gigantic shell at near relativistic velocities. The shell mirrors a conventional explosive shell, although on an extremely massive scale, and upon detonation will explode with more force than dozens of plasma warheads.[2b]
Ryza-pattern Nova Cannon
The Ryza-pattern Nova Cannon replaces the explosive shell used by the Mars-pattern Nova Cannon with a highly unstable plasma-based macro-bomb. These weapons use much more power than a Stygies-pattern, but are thought to be more effective. Weaponising such a huge quantity of plasma however carries its own risk, as overheating systems can potentially cause damage to the weapon and the ship itself.[2b]
Ammunition
- Doppler Shells - Release large amounts of graviometric waves that will bounce off the hulls of ships and expose hidden enemies.[4]
- Electromagnetic Shells - Designed to interfere with enemy sensors and communications.[4]
- Grav Shells - A newer design, these are extremely difficult to make and as such are extremely rare and dangerous. When detonated, Grav Shells implode in on themselves and create a miniature black hole.[4]
- Rift Shells - Similar to a Vortex Torpedo, except much larger.[4]
Known ships equipped with Nova Cannons
- Ark Mechanicus[5a]
- Apocalypse Class Battleship[6]
- Victory Class Battleship[5b]
- Mars Class Battlecruiser[1a]
- Mercury Class Battlecruiser[5b]
- Dominator Class Cruiser[1b]
Individual Vessels
- Alcazar Remembered - A Battle Barge of the Fists Exemplar, ca. 544.M32 (retrofit).[7]
- Oberon - An Ordinatus.[8]
