It doesn't remove fuel entirely, they still need an engine to circularize their orbit.
> The velocity boost provided by the accelerator's electric drive results in a 4x reduction in the fuel required to reach orbit, a 10x reduction in cost, and the ability to launch multiple times per day.
Wow are there issues with making things like chips that can even survive that? I remember when I was a scientist and 10,000g was some very high speed centrifuging that you better make sure everything like even glass and plastic can handle.
