US Navy Demonstrates World's Most Powerful EMRG at 10 Megajoules
Feb 4, 2008


The Navy's Office of Naval Research successfully conducted a record-setting firing of an electromagnetic rail gun at Naval Surface Warfare Center, Dahlgren Virginia.

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.

Whatever next! 200 miles? And no explosives?

Does a ship need the capacity to fire at a target 200 miles away? Why not use planes or rockets?

I am surprised that so few showed an interest in this Herk.
That post actually announced an advancement in naval history equal to changing from wooden ships to ironclads.
We are living in history.
Although the technology is for only the good guys yet, I doubt if it will be very long before all navies have that weapon.

Actually I was very interested to hear about this, having studied electromagnetic theory at university. I'm only surprised it has taken this long to 'go live', although I expect the design was there early on and the majority of time was spent refining into a weapon that was practical and affordable. Would be interesting to be able to look back on this naval era the way we look back on say, the ships of the late 19th and early 20th century.

By 2050 to 2100, that is exactly what will be happening.
There will be all these naval books coming out that will show the old days of WW1 and WW2 naval guns with magazines and explosive propellants.
Young boys will ask their fathers if it were true.
Meantime navies will be slugging it out with EMRGs.

That's if we are all still here.

Yeah, well if we are still here we will have them.
