USS Enterprise NCC-1701-E
The sixth starship to bear the name Enterprise (excluding NX-01,) the Enterprise-E was commissioned on stardate 49827.5. Commanded by Captain Jean-Luc Picard, the Enterprise has played a key role in several incidents, including 2 Borg incursions (Star Trek First Contact, Star Trek Dragon episode "Lonesome Road,) as well as a few incidents with the Vrol.
By far, this is one of my three favorite classes of starships, the Sovereign class. When I saw it for the first time with my cousin in theaters, I was amazed with the ship, I loved it! Great design, in my opinion! The Enterprise-E most definitely fits the role of the Federation flagship :)
