Which Enterprise? Kirk's? Picard's? Riker's? one of the future ones? Archer's?
Kirk had NC-1701(No Bloody letter - so Scott said when he was on the D). Then 1701-A and 1701-B. 1701-C was in between the TOS and TNG, seen in the episode where the universe shifts and Yar didn't die as she was supposed to, so she went back in time.... Picard had NC-1701-D and NC-1701-E also we saw a NC-1701-F and on Enterprise they mentioned in a time travel episode the NC-1701-J
Archer's was NX-01
then there was a Future Enterprise that had no call letter I could make out.....
any of those the one you were looking for?
also the USS Enterprise in the Navy is the CVN 65
the USS Enterprise in WWII was CV-6
and I don't want to dig up any more, gonna go to bed......
but first a new question..... since one of those has to be right....
Which Voyager Crew Member changed places with himself after his original version died in an early encounter with the Phage carrying Viddians fractured Voyager into two vessels on top of each other...... and who did he take over to the other voyager with him?
