railguns are so kewl. thing is as it says in the article there are no electronics that'll take the forces imparted on it during firing. so they've got to come up with something new for warhead guidence.
the fact that this has so much energy involved means they don't NEED explosives and that is so kewl!
imagine seeing one fired at a flat trajectory? the wave that'll follow it would be awsome! something akin to the parting of the red sea i bet
