We could be seeing a railgun and missile equipped ship soon. Engaging targets with the range of an aircraft carrier without risking multimillion dollar aircraft. From what I understand about railguns, a 32 megajoule model can hit with a little bit more force than a tomahawk hawk missile's impact and explosive warhead combined, due to it's sheer speed. And the projectile is much, much cheaper than a tomahawk missile because it's nothing more than a giant solid chunk of pointed metal. I see much potential in the railgun, it could make a nice addition to the world's arsenal and could make gun based artillery weapons far more potent.
Plus, look at that firetrail from the bullets they fire and tell me it's not awesome looking.
