Out of curiosity, is there anything in on-screen canon that establishes when the original Enterprise, NCC-1701, was launched? The Okuda Chronology says 2245, but is this stated on screen anywhere? My point being, is there any reason why the 1701 couldn't have been launched in 2235 instead in the Prime Universe and/or the New Universe?
"Canon is only important to certain people because they have to cling to their knowledge of the minutiae. Open your mind! Be a Star Trek fan and open your mind and say, 'Where does Star Trek want to take me now'." - Leonard Nimoy
