Electro-Magnetic Laboratory Rail Gun

[3] The first industry-built launcher, a 32-megajoule prototype demonstrator made by BAE Systems, arrived at the Naval Surface Warfare Center (NSWC) Dahlgren in January 2012.

[4] A previous 32-megajoule installation existed at Kirkcudbright Electromagnetic Launch Facility at the Dundrennan Weapons Testing Range in Scotland, United Kingdom.

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.

[6] Phase II, which started in 2012, was planned to advance the technology for transition to an acquisition program, concentrating on demonstrating a repeated rate fire capability.

By late 1944, the theory behind his electric anti-aircraft gun had been worked out sufficiently to allow the Luftwaffe's Flak Command to issue a specification, which demanded a muzzle velocity of 2,000 m/s (4,500 mph; 7,200 km/h; 6,600 ft/s) and a projectile containing 0.5 kg (1.1 lb) of explosive.
