Like previous generations, there continues to be the situation where we take three steps forward, two steps back. The new projectile, while more damaging per round, requires its own 3 Terrawatt generator.
These potent weapons take ever so slightly less space than the previous generation. In the words of our research coordinator, "w00t."
The railgun continues to be surprisingly effective in demonstrations. The new projectile prototype used during testing can pierce over 75 meters of solid steel. Against ships that have little or no serious armor this can be incredibly damaging.
