well, it has pretty good delta V, i got like a third of the way to the north pole in the atmosphere, and it has great ISP in atmospher or space. it also has 2 refinerys, and one idea is that it could be used as a base module, with tons of power from its 4 2.5 meter nuclear reactors and 10 1.25 meter fusion reactors, and its refinerys, you could just land it on the moon and it would do a great job of supplying power and refining.
