				You guys do realize this is a nuclear artillery gun. The explosion is so big big because the shell IS A FREAKING NUKE. The cameras used radio or wire to send the images to a recorder miles away.

				A gun on rails is not a railgun 

 A linear DC motor is a railgun. The germans made two huge cannons, yes, but that is the american 280mm "Atomic Annie". Read all about it here:

				I figured it would be obvious, what it was since the link has the words, "atomic bomb" in it. You guys need some common sense. Besides, if this were a rail gun, where are the tracks?

				ok it is a atomic annie and the carrage looks just like a cannon that rolles on rails or a rail gun just smaller

				The reason it rolls back is to absorb the recoil. Kinda like a piston bumper. All artillery uses this technique, not just "rail guns" which usually fire perpindicular to the track.

				i thought that a rail gun used high voltage and a magnetic projectile accellerated by a rail with the opposite polarity or something like that?

				Yeah that is how a rail gun works. I would love to make one but SooooO much money to build a decent one.
