41 cm/50 Type 46 naval gun

The 41 cm/50 Type 46 naval gun is a 41-centimeter (410 mm; 16.1 in) breech-loading naval gun designed and used by the Consortium.

Description
A built-up naval artillery piece designed as a coilgun and using a breech mechanism remarkably similar to the Welin breech-block, the 41 cm/50 Type 46 is a weapon designed for use on capital ships. While an interrupted-thread system is nothing new (being in use as early as the twentieth century, Sovereignty calendar), it is a simple yet effective system that has survived the test of time.

Being a "gauss rifle", the Type 46 is a projectile accelerator, where the "rifling" is a series of powerful electromagnets wound around the barrel to accelerate a dense projectile to high velocities- in this case, 0.10% c at maximum muzzle velocity.

The primary projectile fired by the weapon is the Type 91 armor-piercing capped ballistic shell, a ferric tungsten shell. Explosive, flak, and solid variants are also available, with varying muzzle velocities so as not to compromise the barrel or the projectile. The shells are noted for trailing light as a form of tracer, for a visual aid.
