US testing electromagnetic warheads which are "game-changers"
Days after North Korea’s latest missile test failed, the US Office of Naval Research published a video which captured the explosive guns in action on YouTube.
Cannons are filmed blasting away in countless directions as fiery smoke crosses the sky.
The Naval Research Office described the railgun “as a true warfighter game changer”.
The Office added: “Using its extreme speed on impact, the kinetic energy warhead eliminates the hazards of high explosives in the ship and unexploded ordnance on the battlefield.”
On Tuesday, Pyongyang tried to launch four missiles from near Eastern Motoyama, according to South Korea's ministry of defence.
The failed test followed the warnings from Choe Myong Nam, deputy ambassador at the North Korean mission to the United Nations in Geneva who warned the hermit kingdom are “prioritising” the development of inter-continental ballistic missiles (ICBM), capable of striking the US.
Describing the project in 2014, Former Rear Admiral Matt Klunder, the then chief of Naval Research, reportedly said: “[It] will give our adversaries a huge moment of pause to go: ‘Do I even want to go engage a naval ship?
“Frankly, we think it might be the right time for them to know what we’ve been doing behind closed doors in a 'Star Wars' fashion. It’s now reality. It’s not science fiction. It’s real and you can look at it.”
Robert Freeman, a spokesman for the Office of Naval Research told US News and World Report that the electromagnetic cannon could “tear through sheets of metal” whilst transforming a ship’s ammunition needs.
He added: “Our need to carry gunpowder with is a big vulnerability to our ships. A rail gun could eliminate that need.”

The weapons are capable of obliterating heavily armoured targets at a range of up to 126 miles and the astonishing speed of 4,500mph.
Referred to as “Star Wars technology” the missiles are fuelled solely by electricity which will reduce a ship’s “vulnerability”.
