Electromagnetic Railgun Shoots Target 100 Miles Away


(Video Link)


A railgun is a weapon that uses electromagnets to accelerate a projectile to very high speeds. The US Navy has been developing one for several years. Today they fired a shot at Mach 7 at a target 100 miles away:

An electromagnetic railgun offers a velocity previously unattainable in a conventional weapon, speeds that are incredibly powerful on their own. In fact, since the projectile doesn't have any explosives itself, it relies upon that kinetic energy to do damage. And at 11 a.m. today, the Navy produced a 33-megajoule firing -- more than three times the previous record set by the Navy in 2008.[...]

Ellis says the Navy has invested about $211 million in the program since 2005, since the railgun provides many significant advantages over convention weapons. For one thing, a railgun offers 2 to 3 times the velocity of a conventional big gun, so that it can hit its target within 6 minutes. By contrast, a guided cruise missile travels at subsonic speeds, meaning that the intended target could be gone by the time it reaches its destination.

Furthermore, current U.S. Navy guns can only reach targets about 13 miles away. The railgun being tested today could reach an enemy 100 miles away. And with current GPS guidance systems it could do so with pinpoint accuracy. The Navy hopes to eventually extend the range beyond 200 miles.

We should put more mony in it look at plasma it laves behind it is cool chep only sevrel Tomahawks would make up the the mony we put in this program

$211m in 5 years?? wow, we need these guys to give lessons to the GAO and congress and the executive branch. they blow that much in a MONTH and get jack$#!+ done for it.

Side note, how do I mount one of these to the roof of my beetle??

Nice video!
But this is only what they want us to see or believe...
Usually technology that is brought into the public eye is already several years out of date. Do you actually think they would show us the real weapon? NO! It would be a matter of national security.

While this is a weapon, railguns are a feasible single stage to orbit solution for unmanned payloads obviously.

Also Mach 7 is the operating speed of a Scramjet so you could use this to launch one immediately to its normal operating speed since a scramjet cant operate at subsonic speeds.

You could probably use it to weld things, pile drive foundations, mine without explosives...

Lots of possibilities.

What an incredible waste of money. There are many more logical weapons systems that could be funded, ones that might help us combat our enemies. We have no problem killing people at a distance, and all the people that want to hurt us know this and take precautions to not be targeted by our cruise missiles, bombers, special operations teams, satellite intelligence, etc, etc. How much are they spending on the 'steam cannon?' Or how about the 'sun refractory death ray'? Why don't they just take our tax money and burn it in a big barrel and call it a 'precautionary sacrifice to Mars.'
