^ Actually United Earth was formed in 2123. It wasn't until 2150 that Australia joined, though. That was the last holdout.
...Or what it looks like, for that matter. Perhaps one of the older classes we saw was it?
Possibly, but the Daedalus
supposedly had a crew of over 200, and I doubt those older ships could hold that many.
There are at least two different designs for this ship that I've seen. There's the one with the globular primary hull that most of us are aware of. Then there's the recent comic which showed that class as basically an NX, but with Abrams-1701 nacelles!
