The U S Navy set a world record in a powerful railgun shot: 33 megajoules of power.  They beat their old record of 2 megajoules set in 2008.
What this means is that a bullet about 4 inches in diameter and a foot or so long can destroy targets up to 110 nautical miles away.
It is being reported that this weapon will eliminate much of the need for explosives aboard a ship that would usually be needed to fire traditional guns which only have a range of 20 miles or so.
The projectile traveled at Mach 8 which is more than 6,100 MPH.
Look at the video of the record-breaking test shot.

Wired reports: There wasn’t much left of the 23-pound bullet, just a scalded piece of squat metal. That’s what happens when an enormous electromagnetic gun sends its ammo rocketing 5,500 feet in a single second.

Mashable tells us: This kind of weapon requires no explosion to get a projectile from point A to point B. Rather, a railgun uses an electromagnetic current to accomplish the task, and it does so at previously unimaginable velocities.
The railgun has no moving parts except for the projectile.
It does not use any explosives, which means it makes for a safer and greener operating environment.
