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
- first large-scale railgun build in 1970 by John P. Barber in Australian National University
- today biggest railgun located in Virginia, USA (at Naval Surface Warfare Center’s Dahlgren
Division Laboratory)

Today record of railgunSpeed 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
