Okay I was forced to watch it again, TATV. They are what.. 5 or 7 years after Terra Prime and the NX-01 is going back to earth to be mothballed. I don't get it. Sure they can go Warp 7 now and don't need this class of ship to explore with but is earth so replete with warp vessels that they don't actually need this still relatively young starship?

). It's also possible all that warp 5.2ing took it's toll.
