The US Navy is testing an electromagnetic gun that can fire projectiles at six times the speed of sound.
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 are created by electricity on the ship and a ‘pulse power system’ to sent propellants flying at 4,500mph.
The technology has previously been shown to penetrate concrete at 100 miles away.
