I know this is outside the Sci-Fi world of these forums, but there is an online petition to have the third Ford class nuclear carrier, CVN-80, be named "Enterprise". The current vessel CVN-65 is scheduled to be decommissioned in either 2013 or 2014.
For me, it was my fondness for the name Enterprise from my WW2 history studies that led me into the world of Star Trek as a kid. The series would not have been the same to me if the ship had been named "Yorktown" or such. There has always been something about the name ENTERPRISE that has resonated with me from the legendary exploits of Halsey to the battles of Midway and Guadalcanal. There should ALWAYS be a U.S.S. Enterprise in the United States Navy.
