They are an electro-magnetic "gun" that fires a highly conductive projectile faster than a traditional round and without any explosives.|||It is a weapon that is still in development for the US Navy called a rail gun which according to some experts could be on board US Navy ships as early as 2020,





While it did look like a laser the actual rail gun being built is designed to fire a tungston rod a super high speeds. Basically put the gun fires this super dense rod to the limits of the atmosphere then as it comes down it approaches an amazing speed while a gps reciever guides the rod on to target. When it hits it hits with such speed it almost like a mini astroid or meteor. As a result as seen in the movie there is nothing left of the target in the case of the movie a decepticon.|||JUST came from seeing Transformers and I must say.... I am somewhat disapointed! To me was not at all what was hyped up to be. Where are the dinobots!? And they could've did without all that profanity! If you have young kids, I would not recommend you take them to to see the movie! I don't know, I mean it was ok but not a GREAT movie. That part about the laser like gun was cool though. I was expecting to see more nemesis type fighting AMONGST THE TRANSFORMERS THEMSELVES.|||It is called the rail gun. The part where they tried shooting the huge *** combined transformer off the pyrmaid right? Yeah thats it.|||Yeah, sadly they prefer sending in soldiers to die instead of using that weapon against the Decepticons.|||A railgun. That tore devy apart!|||I'm pretty sure they called it a 'Rail Gun" .. some sort of prototype weapon..
