Dual 250mm Railgun II

This battleship-sized weapon is a double-barreled version of the cruiser class 250mm railgun. Railguns use magnetic rails to fire solid chunks of matter at hypersonic speed. The accurate range of railguns is very good, but due to technical limitations it cannot use onboard guidance. This results in a fairly rapid drop in accuracy at extreme ranges. Requires either regular or advanced hybrid charge types: Antimatter, Iridium, Iron, Lead, Plutonium, Thorium, Tungsten, Uranium, Javelin, Spike.
