In fact, the "Thor" was not pure railgun, what would use the pure magnetic accelerator. This system was mentioned to be like the extremely powerful airgun. Behind the accelerator was a chamber, what was filled with the hydrogen and oxygen gases, and then this gas combination would be ignited with the electric arc, and that would push the iron projectile to the accelerator. Then the magnetic rail would give extra speed to that projectile. That magnetic accelerator could have the capacity, that it can be pulled inside the satellite, that nobody sees it from outside. The rail would be kilometers long, and it can be made extremel...
