Railgun # 4
For years, the Railgun was an unrealistic and expensive endeavour that only truly existed in the realm of movies, folk lore and general impracticality. However, in recent years the military has made major strides toward the Railgun becoming a reality. The technology is complex but in short, recent Railgun’s that have been tested are capable of launching a seven pound projectile to speeds of more than 5,000 MPH. Truly, a terrifyingly powerful modern weapon.
