X13 Main Battle Cannon

"Think of it as a revolver a really big revolver, that can also destroy planets"- Timothy Zahn

The X13 Main Battle Cannon is the heavy cannon of the AEF Enforcer designed by Timothy Zahn. Capable of destroying Capital ships in one shot and in its high powered setting even capable of destroying a planet.

Design
The X13 Battle Cannon has two barrels so that it can be used as both an energy weapon and as a railgun. The energy weapon mode operates by first gathering energy from the main reactor into a ball and then the energy is shot out of the barrel while being charged by capacitors lining the weapon's barrel. The railgun weapon mode operates on a similar methodology a shell is loaded into the weapon, the shell is then launched down the barrel at a supersonic velocity with the shell being sped up by magnetic accelerators in the barrel. Power can be rerouted to the X13 from the shield's absorption capacitors and can be used to enhance the power of the weapon.

Mounting
The X13 is directly integrated into the AEF Enforcer's superstructure. In drydock the ship was built around this weapon.

Ammunition
The shell for the railgun is made of Neutronium.
