Gonzo, schematics have not been given. You’ll notice the pictures show a railgun enclosed by a pretty thorough casing. All the thermal management goodies, vital to making this thing feasible, are hidden. The only message sent to our enemies is “This costs 1/100th of an equivalent missile engagement. Still want to attack?”

I see the physics of this high speed projectile has some people confused about the fire around the projectiles’ path. Just think about what is happening, as when a similar high speed meteor enters the earth’s atmosphere, and you will have your answer. With initial velocities this high, the projectiles are causing the air to ignite for a short distance around them. That’s just how fast they are traveling!

Why in hell do we give the enemy ….secret weapons info /pictures/schematics … I think all weapons should stay secret… Even in use….in today age….come on people stop giving all Americas enemies ….our winning hand…

I wonder why there is still a flame behind the projectile? That is very bizarre ???
What is the recoil like? YOu can not put a muzzle brake on that baby as there should not be any propelling gases behind projectile!

The shape of the projectile is not very aerodynamic.

Editor: Nic, look at the top video carefully all the way through. The projectile is a needle-like dart with fins. It is carried in sabot with a square shape. The Sabot is discarded when the projectile leaves the rail gun muzzle. We’re not sure about the source of the flames, but it may be part of the sabot vaporizing and burning…

Unclear what the terminal velocity is at 110 mi., unlikely anywhere near Mach 7.

1/4 minute at 110 miles should be 37.4′ if I did my math right. Can they put a payload in it though… if not once reaching 110 miles will it be like watching Marvin the Martian land on the moon nose first.

When is Hornady coming out with a Vmax for this? Would make a fine groundhog setup.

Thank god it doesn’t use Varget as a propellant.

Putting that much electricity in a boat reminds me of all the osha safety videos where they guy uses power tools in the swimming pool.
