That system was developed by BAE Armament Systems Division (formerly United Defense, more formerly FMC (not Ford)), in Minneapolis, MN.
The flash and fireball isn't explosives, it's the KE of the mass that was traveling at Mach umpty-ump being converted to heat and destroying the projectile.

They have been working on rail gun development of at least 20 years. There are some big problems to overcome, but if anyone can, those guys can.

Who said "The flash and fireball is explosives"?
Yes I remember when I was working for Ronnie in the 1980's there was research on the rail gun.

No one Pablo, but someone would have. It looks like more than just a couple of hunks of metal being flung together, but that's all it is.
IIRC, a 120mm cannon (M1A2 Abrams) projectile has about 12 Mega Joules KE instead of the 32 MJ this rail gun is set to deliver.

After I get the bike running well. Maybe I can make a kit and sell it on fleabay and eggslist. Have them hecho in China.

There appeared to be flame and gas discharge from the barrel of the weapon which seems odd for a Gauss based system. The impact shown here makes sense given the energy.

It's probably hot as hades in there with the E.M. field metal and whatnot...possible "sabot" burning, possible ionised "whatever"

Looking at it more.
at around the 8 second mark, it's long left the rail gun. The sparks and everything indicating a big electrical discharge are dissipating...no "flames" or anything.
There appears to be a penetration into the target "chamber".
I'm starting to think that with the high speed camera in the target chamber they are using some sort of optical pressure effect (I'm thinking along the lines of Schlieren, but I've only seen that done at uni to produce static pressure profiles, and about 20 years ago).
I don't think there's flames.

"Because the railgun uses electricity and not gunpowder to fire projectiles, it eliminates the possibility of explosions on ships."
It's too bad the powerlabs guy isn't allowed to work for the US military... The Manhattan Project could never happen, today.

I think there is more to that story.

Shannow, what I was looking at was at the 13 second mark as the projectile leaves the barrel. Maybe super heated gas (air) as you say?

Im involved on the fringe with that program... a lot of the technologies we are developing need to feed into and help devellop the ship architectures that support such weapons.
Neat stuff, I was going to post yesterday, but got caught up doing other stuff.

This was sent to me by a friend after I showed him this article.
My father was a Navy veteran, although he never saw
combat duty in WWI. After enlisting, the Navy sent
my dad to Harvard University, where he attended the
Radio School which the Navy maintained there. The
war was over before he completed the training. Then
my dad joined the telephone company and worked himself
up to a position of Senior Instructor in charge of on
job training for the Western Michigan division of
Michigan Bell.
While I was in grade school, my dad would take me to
his office on Saturday mornings where he would teach
me about electrical circuits and show me training films.
One Saturday my dad showed me something he was working on.
It was a working model of an electromagnetic gun! He had
taken a large fiberboard tube like those used to hold
rolls of carpet, and wound it with a number of separate
coils of heavy gauge wire. He had mounted this tube on
a wooden cabinet, inside of which were a number of large
storage batteries, bigger than car batteries, the type
used for standby power in the central offices. There were
also circuits to control the gun - a stepping switch and
large high current contactors which operated sequentially
from the stepping switch. This system would produce a
traveling electromagnetic wave inside of the carpet tube
as the coils were pulsed in sequence by the stepper.
My dad would place a bar of iron in the end of the tube,
press the start button, the stepping switch and the
contactors would go "brrrrup!", and the bar of iron would
sail out the other end of the tube and hit the wall of
my dad's office, about ten feet away!
My dad wrote up an unsolicited proposal and sent it to
the Navy, suggesting that they should research this for
battleship guns. My dad received a polite letter from
the Navy essentially saying "Thanks, but no thanks".
I sure wish I had some documentation to prove this, but
none has survived the years. Maybe his proposal and the
Navy's reply still exist somewhere in some obscure Navy
archives. I believe the date must have been around 1947
or 1948.
