Fascinating. The seeming scale of the picture looks like they have gotten these down to a managable size now. Wish they would have discussed the power generation/consumption of the gun and how frequently it can be fired.
That's probably a state secret, don't you think? Not sure the Navy wants every country to start their own super-weapon production, now that they have just got theirs ...
Lol, I suppose, if youre a stickler for "state secrets" and "national security".
I was really more interested in whether or not they had worked out the kinks outlined in the Wiki article on railguns such as the rails needing replacement after almost ever shot. Also, as Gorth pointed out, they still require a ridiculous amount of juice.
