As to the scalability argument, the issue isn't so much in terms of cost. As it is we have yet to find a cost effective means of putting stuff into orbit, and this technology would have the potential to reduce costs considerably. The largest problem to overcome is in terms of g-force. Whereas a rocket will put it's payload under a relatively constant number of g's through take-off, the electromagnetic accelerator puts an absolutely enormous amount of force initially on the projectile, making it very tricky for any payload to survive, whether human, electronic, or otherwise.
Awesome. I'm a fan of moderation in defense spending. The fact that this weapon is (or will be) more powerful than current weapons and that it's less costly is a huge plus for both sides of the table. Our nation can be safer at a smaller price. Considering the cost of the war in Iraq, I'd imagine that there will need to be some moderation on spending in the near future. Technology is simply amazing.
Why dont they just cover the barrels with sandbagsin theory the energy should be converted to an annoying sound and possible heat instead of a destroyed barrel
As the bullet travels down the barrel of the gun there is the force of the expanding gas that is exerted upon the barrel and the bullet. The barrel and the bullet exert an opposing force but the bullet is the "weak link" so to speak so it moves in the path of least resistance and creates a net force vector in the direction of the shooter (which would be the case whether there was a bullet there or not). Has no one ever noticed that there really is no recoil until the bullet exits the barrel? In fact, the most recoil would probably occur first when the bullet is fired and the force vector of the gas is pointed mostly toward the shooter, it would then dip as the force of the gas is more evenly distributed and finally spikes when the bullet exits and high pressure gas hits the low pressure atmosphere and the force points more directly toward the shooter.If the barrel were so long that the bullet never exited it then I don't think there would be much kickback at all. The barrel will have absorbed nearly all the force being exerted by the explosion.

@ RicktheBrickYou couldn't be more wrong. If the Navy has a gun ship in range, they will attack the target. Here's direct proof that you are wrong ... this guy has a website detailing his military service over the years, and the second picture from the bottom shows the USS Missouri using its main guns to attack Iraqi targets in the first gulf war (early 1990s).<a class="user" href="http://web.umr.edu/~rogersda/military_service/battleship_service.htm">http://web.umr.edu/~rogersda/military_service/battleship_service.htm</a>More details of the USS Missouri.<a class="user" href="http://en.wikipedia.org/wiki/USS_Missouri_(BB-63)">http://en.wikipedia.org/wiki/USS_Missouri_(BB-63)</a>

"I'd be willing to bet it'd be quite a bit less than the ideal 45 degree angle though."OIC! so the boat just tips over then?
