The UG-324 is a large railgun turret designed to replace the UG-311 for mid-range anti-starship combat, and can fire projectiles at 0.0001c or about 30,000 m/s.

The UG-324 was designed late in 2314 by a collaboration between the Magnetic Assembly, Stellar Defense, and Atlantica Electromotive as part of an ongoing process to refine and update the weapon offerings being made to the American Union. The incremental upgrades to the system weren't deemed useful enough to bother with updating the design and as such the system sat unused and undeployed until CE 2320 and the overwhelming losses suffered by Union Forces at the hands of Magnetic Assembly forces deployed by the New Cambridge Executive Council after their exit from the American Union. Stellar Defense was quick to pitch the UG-324 again as a 'Purely Stellar Defense Design' to help deal with fears that Magnetic Assembly electronic warfare or sabotage may have made its way into the equipment itself.

Facing an election year and an open rebellion the current administration of the American Union would approve the Gold-Plating of its Statesmen class warships. This would involve large scale purchases of the latest weapons from Stellar Defense and massive contracts to modernize the existing fleet of Statesmen.

The UG-311 has an armored upper turret, and an unarmored lower section that is supposed to sit inside of a ship’s hull.

The upper section mounts A single 100mm railgun. Improvements in materials science allow the UG-311 railgun to be more than twice as reliable as a single UG-324 and sustain a much greater rate of fire. This allows the UG-324 turret to only mount a single larger cannon and still be lighter than the UG-311. A pair of thermal-electro-optical sensors for target acquisition are located on either side of the turret. These are supported by a highly accurate fire control radar mounted ontop of the turret. The two rails of each cannon are braced by a transparent composite material that allows for easy inspection of the rails and that distinct ‘dual-rail’ cannon look.

The lower section of the turret contains the electronics for managing the weapon, capacitors that are designed to be fed by the connected ship’s power systems, and the ammunition magazine for the weapon system itself.

Ammo Capacity: 2,400 rounds in magazine

The Railgun fires a variety of 100mm slugs. Though these are typically unguided specially coated tungsten rounds, there are a range of other rounds available such as bursting rounds and railgun launched guided missiles. The reasonably high fire rate and high velocity of the projectile generally makes such specialty ammunition unnecessary.
