4. Coilgun -invented by Kristian Olaf Birkeland (1867 –1917) -using magnetic forces to accelerate projectile -projectiles are ferromagnetic

5. 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)

6. Railgun in Virginia

7. Principe of Railgun -using magnetic forces to accelerate projectile (Lorentz Force)

8. Today record of railgun Speed of projectile: 3,2km/s Weight of projectile: 3,6 kg Kinetic energy of projectile: 33MJ

9. 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
