This particular test would be the first time an electromagnetic railgun (EM railgun) would be demonstrated at sea, which would mark yet another significant milestone in the world of naval combat, and I suppose that this would mark a change as huge as moving from boarding another ship to using cannons against one another.
EM railgun technology would rely on an electromagnetic force known as the Lorenz Force in order to rapidly accelerate and launch a projectile between two conductive rails. This particular guided projectile can launch at extremely high velocities, so much so it can hit a target far, far away that conventional guns simply cannot reach, all the while without losing much kinetic energy to damage the target and doing away with the need for a high explosive payload.
Among the high-energy EM railgun’s targets? Being a lethal and effective weapon against multiple threats, including enemy warships, small boats, aircraft, missiles and land-based targets. Looks like years of research is finally about to bear fruit. [Press Release]
