Re: A Military Star Fleet and UESPA
UESPA was probably supposed to be a future version of NASA. Then they changed their minds and went with Starfleet. UESPA and "Earth ship" pretty much disappear in the first season and are treated like they never existed. UESPA was revived in later shows but Earth ship wasn't heard of again till Enterprise
which was explicitly about an Earth ship.
The boring one, the one with Khan, the one where Spock returns, the one with whales, the dumb one, the last one, the one with Kirk, the one with the Borg, the stupid one, the bad one, the new one, the other one with Khan.
