Railguns

Despite efforts from countries like China, Japan, and the U.S., challenges like the immense energy required and the wear on conductive rails have hindered progress.  The U.S. Navy invested heavily in electromagnetic railguns, but the technology remains mostly in the research stage.  Future success hinges on overcoming power and durability issues, making practical deployment still a distant goal.

Why Railgun Development Faces Immense Hurdles
Among the earliest efforts occurred during the First World War, when French designer Andre Louis Octave Fauchon-Villeplee proposed an electric cannon could fire a projectile further than the explosive ordnance of the era. 

His concept caught the attention of the French military, which was seeking a weapon that could rival such long-range cannons as Germany's so-called "Paris Gun." Under the direction of the Director of Inventions at the French Ministry of Armaments in 1918, Fauchon-Villeplee was charged with developing a thirty to fifty millimeter electricannon based on his simple design.

The First World War ended before Fauchon-Villeplee's design could be perfected – and more than a century later, the development of the weapons has continued with only limited success.     READ MORE...
