I always write in various forum that Chinese buying German Megalev technology has eventual application in EM guns and EM aircraft launch. Chinese is operating EM rail for decades, and it is just a matter of time EM rail become EM aircraft launch system.
While Gerald Ford class has EM launch system, they are straight out from R&D. It will be problematic and maintenance prone.
If you design heavy Megalev system, it wont be that difficult to scale down the weight and design a "megalev lite" trading weight for massive increase in velocity.
