A new prototype of the Navy's weapon of the future just completed its first test, blasting a chunk of metal through the air at speeds up to 5,600 MPH. Watch below as the Navy's electromagnetic railgun spews a formidable jet of orange flame.
The Navy just broke its own record for an awesomely powerful railgun, which can hurl a projectile hundreds of miles at superfast speeds without using explosives.
Today's 33-megajoule shot — powerful enough to launch 33 Smart cars at 100 mph — means the Navy can fire projectiles at least 125 miles, keeping military personnel at a safe distance from their targets, according to the Office of Naval Research.

Um, wow. This video comes from a test firing of the Navys Elecromagnetic Railgun (EMRG), which was carried out yesterday at the Naval Surface Warfare Center in Dahlgren, Virginia. The gun—which generates a powerful electromagnetic field to hurl projectiles at extremely high speeds—is rated at 32 megajoules, but the railgun engineers have to work up to that number slowly: this test was designed to reach a record-setting muzzle energy rating of 10 MJ. (The actual number turned out to be 10.64 MJ, according to Collin Babb with the Office of Naval Research.)
One big question this video begs is, what causes the giant fireball?
