The Railgun has been in development since 1918 when French inventor Louis Octave Fauchon-Villeplee invented the electric cannon. In his device, two parallel busbars are connected by the wings of a projectile and the whole apparatus, surrounded by a magnetic field, propelled a projectile forward.
Since 1918, there have been numerous innovations to this technology in order to improve it, but nothing has ever officially been used in a combat capacity. The U.S. Navy specifically has taken an interest in this technology, hoping to equip it on a number of ships to give them an edge in naval warfare.
The Office of Naval Research (ONR) has recently released a video in July of 2017 that shows one of their experimental Railguns firing the first ever multi-shot salvo. Here is the test footage.
