"I will only accept a naval vessel which has been equipped with a railgun IRL, be it through testing or design intention, as legitimate in the RP. The rest I support the voiding of. IE raised the example of the Zumwalt. The designers planned for one of the Zumwalt's 155mm guns to be equipped with a railgun. I think it would not be unrealistic for a railgun-equipped Zumwalt to roam the seas provided it sticks to specifications as it was designed for it. But it would be unrealistic if the Zumwalt had two railguns, or if an Iowa-class battleship was fitted with railguns in its turrets, or if an aircraft carrier suddenly got one."

I'll leave it up to you, but the option does exist and it is explicitly endorsed.
