OT - How About 2520mps (8268fps) Muzzle Velocity?
Was loading up some .45LC to about 850fps and took a break to read the news. Saw this article about rounds moving out at 100x that speed! I guess this 10 megajoules shot is the Navy equivalent of a "cat sneeze" load as they are eventually going to work their way up to a 64 megajoules test...

The burning materials seen in the photos are surface matter from the projectile which has burned free due to friction with the rail gun bore. Also note the over-pressure wave leading the projectile which has been captured by the high speed camera.)
U.S. Navy Demonstrates World's Most Powerful EMRG at 10 Megajoules
Story Number: NNS080201-02
Release Date: 2/1/2008 8:47:00 AM
From Office of Naval Research Public Affairs
080131-N-0000X-001 DAHLGREN, Va. (Jan. 31, 2008) Photograph taken from a high-speed video camera during a record-setting firing of an electromagnetic railgun (EMRG) at Naval Surface Warfare Center, Dahlgren, Va., on January 31, 2008, firing at 10.64MJ (megajoules) with a muzzle velocity of 2520 meters per second. The Office of Naval Research's EMRG program is part of the Department of the Navy's Science and Technology investments, focused on developing new technologies to support Navy and Marine Corps war fighting needs.

DAHLGREN, Va. (NNS) -- The Navy's Office of Naval Research (ONR) successfully conducted a record-setting firing of an electromagnetic rail gun at Naval Surface Warfare Center, Dahlgren.
An invited audience, including the Chief of Naval Operations Adm. Gary Roughead, who witnessed this revolutionary technology in action.
Roughead noted, "We should never lose sight of always looking for the next big thing, always looking to make our capability better, more effective than what anyone else can put on the battlefield."
He emphasized, "I never ever want to see a Sailor or Marine in a fair fight. I always want them to have the advantage."
ONR's Electromagnetic Rail Gun (EMRG) program is part of the Department of the Navy's Science and Technology investments, focused on developing new technologies to support Navy and Marine Corps war fighting needs.
ONR has facilitated a key partnership between leading scientists and engineers from Boeing, Charles Stark Draper Lab, Inc., General Atomics, Department of Energy (Lawrence Livermore National Laboratory), U.S. Naval Academy, Naval Postgraduate School, Naval Sea Systems Command (PMS 500), Naval Surface Warfare Center – Carderock and Dahlgren Divisions, the U.S. Army and United Kingdom.
"We are seeing the culmination of years of research coming together to bring focus to exciting new technology," said Chief of Naval Research, Rear Adm. Bill Landay. "Here at ONR we are striving to move S&T from vision to results."
The technology uses high power electromagnetic energy instead of explosive chemical propellants (energetics) to propel a projectile farther and faster than any preceding gun. At full capability, the rail gun will be able to fire a projectile more than 200 nautical miles at a muzzle velocity of mach seven and impacting its target at mach five. In contrast, the current Navy gun, MK 45 five-inch gun, has a range of nearly 20 miles. The high velocity projectile will destroy its targets due to its kinetic energy rather than with conventional explosives.
The safety aspect of the rail gun is one of its greatest potential advantages, according to Dr. Elizabeth D'Andrea, ONR's Electromagnetic Railgun Program Manager. Safety on board ship is increased because no explosives are required to fire the projectile and no explosive rounds are stored in the ship's magazine.
Science and technology challenges met by ONR in the development of the rail gun include development of the launcher, pulse power generation and the guided projectile design. The program's goal is to demonstrate a full capability, integrated railgun prototype by 2016-2018.

Hmmm...
The most excellent feature of explosives are that they are PORTABLE.
This gun would need a nuclear reactor to keep it going in the event of any power outage or fuel shortages.
Energy has to come from SOMEWHERE.
Pretty darn cool though.
I'd love to see mini MINI railguns... (think railgun rifles and pistols!)

I'll bet I can get a second shot off with my Model 94 faster than that guy can.
Government office attracts the power-mad, yet it's people who just want to be left alone to live life on their own terms who are considered dangerous.
History teaches that it's a small window in which people can fight back before it is too dangerous to fight back.

Yep, meant to be ship mounted to help deliver ground support further inland
http://www.military.com/features/0,15240,160195,00.html
They just got a 32MJ delivered and should be testing it soon. I can't see anything wrong with giving the ground troops better, more accurate support.

The 32MJ one above is supposed to launch the projectile at Mach 8.The Marines, in particular, are interested in the potential for rail guns to deliver supporting fire from up to 220 miles away -- around 10 times further than standard ship-mounted cannons -- with rounds landing more quickly and with less advance warning than a volley of Tomahawk cruise missiles.

Howdy,
I am not going to get into the details, mind don't understand all. NASA has done tests on impact hits of fast sh*t out there. Using about a pound of gud ol 4064 they send a slug down the tube pressurizing some gas that they use ,geting into heat from compression and release by transfer from decomp. My head is starting to hurt here. Seems heat is energy and the less used in heat or loss is translated to more umph. Anyway when the slug compresses enough gas to a point, a diaphram busts and send a sabot out to the intended target. Velocities of 26,000fps have been documented . Think of the meat damage.

Just use the appropriate gas check...J Miller wrote: I don't think cast bullets would work too good in that gun.

Anybody here play BattleTech back in the 80's? This sounds like the Gauss cannon to me.

shawn, it doesn't make sense to me........not so much what it's made of, but its shape........round, that is. As I understand it, the absolute outside limit for an accurate shot for a lead round ball from a muzzle-loading rifle was about 400yds. I just don't know how this new one could fly for much , much longer a distance & hit what it's aimed at, with all the wind forces acting on its frontal surface for such a long time. The spire-point or conical projectile shape enabled it to travel accurately for a much longer distance, as opposed to a round ball. Velocity won't help the RB, either. The faster you toss it, the more resistance it'll encounter from air & be deflected by it. That's what I think, anyway...........maybe someone else can add info. jd45
If I remember correctly, some of the first rail gun tests used square blocks as projectiles. Seems the shape isn't all that important. Once you get to a certain speed, you create a shock wave in front of the projectile that's for all intents solid.
At least that's how I remember it
Also, this is really just a demonstrator. If the system is ever deployed, I'm sure the war shot would be different
