This gives me the image of an F14 flipping end over end. Which also entertained me for a few minutes. anyway, The railgun will not fire straight up and decend on a traget, because you can not get electrical equipment which can withstand spontaneus combustion from friction with the atmosphere. It other words, they cant put a guidance mechanism in it, as well as fins/etc. This will almost certainly be a direct fire weapon with a long effective range and kinetic force. The comment "Our point is that if you put millions of joules of energy onto a traget something is going to happen" seems like a reasonable explanation of this weapon. Its meant to rip 30 foot pieces of metal off ships.
