Navy's new Rail Gun
http://www.asminternational.org/new...56/10192/20085491/VIDEO#.VmitpJ4mnqo.facebook
A railgun is an electrically powered electromagnetic projectile launcher. It is made of a pair of parallel conducting rails, along which a sliding armature is accelerated by the electromagnetic effects of a current that flows down one rail, into the armature, and then back along the other rail.

Re: Navy's new Rail Gun
Going to be most powerful gun, it to hard to stop that.

Re: Navy's new Rail Gun
I sometimes don't understand how these damn websites/weblinks can be good one day, then bad several days later ??
Try this for now (at least Youtube won't go away anytime soon)
...ran across this at same time

Re: Navy's new Rail Gun
I don't really understand it, but it looks impressive.

Re: Navy's new Rail Gun
Not really new, but certainly smaller. Maxwell labratories built one for the DOD in the 90's. composite projectile with a mystery alloy on one end, electricity would create plasma behind the projectile projecting it along the rail at the speed of the electrical current. A one x one plastic cube making a 24" hole in plate steel, it took a warehouse of capacitors to run though.

Don't know that I understand that explanation,... about creating an plasma.
I originally thought it was more akin to laying out flat the electro/magnetic field of an electric motor, ....linear acceleration, but perhaps it is a bit more complicated.
The Physics of the Railgun | WIRED

Maybe I should also point out that there is a difference between a railgun and a coilgun. A coilgun uses a series of electromagnetic coils to accelerate a ferromagnetic projectile. For the railgun, the projectile is accelerated because of a current running through the projectile. This means that it only needs to be an electric conductor and not a ferromagnetic material.

Re: Navy's new Rail Gun
The best part is that they can keep on shooting because the ordinance is "cheap" and has no explosives.

Well they will be able to when they get over the problems of heat damage and projectile/armature ablation on the rails. They have a long way to go before they can fire a rapid salvo through one

Re: Navy's new Rail Gun
I think rail guns have been around for a long time, but never fielded.
I remember reading as a kid of rail gun that shot I think a 1" plexiglass cube, low mass of course and not very aerodynamic, but the velocity was so high that it punched through steel armor.
As an Aviator, I don't like them, they are so high velocity that hitting a flying machine is relatively easy.
Actually the Navy has I think an auto-loading 5" gun? that is murder for a helicopter and I think even cruise missiles.
Army years ago demonstrated Laser that could shoot down aircraft and missiles, and I think the Air Force even flew one in a 747?
There is no telling what is out there.

BAE is already started work on that and a rapid loader (10 rd/min) back in Phase II back in early 2014. Pretty good indication that its already been solved being that they are starting sea trials this year. Deployment is "set" for 2019.
This rail gun development has been ridiculously cheap compared to development of the F22 and other Air Force toys.

Good point, .....and will likely see a lot more action.
The F22's are SO EXPENSIVE they likely will not send them into anything even remotely hostile.
