Coilgun
- invented by Kristian Olaf Birkeland (1867 –1917)
- using magnetic forces to accelerate projectile
- projectiles are ferromagnetic
History of Railgun
- invented by Louis Octave Fauchon-Villeplee in 1918
- first plans to use railgun, was purposed by Germany's
Ordnance Office in 1944

in Australian National University
- today biggest railgun located in Virginia, USA
(at Naval Surface Warfare Center’s Dahlgren
Division Laboratory)
Railgun in Virginia
Principe of Railgun
- using magnetic forces to accelerate projectile (Lorentz Force)
Today record of railgun
Speed of projectile:
3,2km/s
Weight of projectile:
3,6 kg
Kinetic energy of
projectile:
33MJ
Weapon in Modern Warfare
- first military railguns will be produced for next generation of
cruisers
- projectiles using kinetic energy to destroy target
- railgun will be powered by small nuclear reactor
- range of railgun 2-3 times bigger than standard technologies
(Medium Range missiles) and 10 times bigger than naval
cannons
