Navy rail gun in action
The US Navy has revealed the latest tests of a radical electromagnetic gun that can fire projectiles at six times the speed of sound.If they can make the barrel hold up to the movement of the projectile it will be a much more economical weapon which extends the range of the ship.
Described as 'Star Wars technology' by researchers, these powerful missiles don't rely on chemical propellants and are fuelled by electricity alone.
Strong magnetic fields a 'pulse power system' is used to send propellants flying at 4,500mph, and the technology has previously been shown to penetrate concrete at 100 miles away.
Railguns are touted as one of the future technologies of warfare, using kinetic and laser energies instead of classic controlled explosives.
'The railgun is a true warfighter game changer,' the Navy says.
'Wide-area coverage, exceptionally quick response and very deep magazines will extend the reach and lethality of ships armed with this technology.
