USS Enterprise NCC-1701-A
The Enterprise-A was launched in 2286 under the command of Captain James Kirk. Although the ship did not participate in as many pivitol roles as its predecessor, the ship did play a key role in the Nimbus III incident as well as the first Khitomer Peace Accords. After the Khitomer Peace Accords, the Enterprise was sent back to Earth to be decomissioned. However, while enroute, it encountered a temporal disturbance as well as a future Federation starship.
Even non-Trek fans are most familiar with this ship and its predecessor. Not one person who lives in a country with public television hasn't heard of the Enterprise or Captain Kirk or Mister Spock or Bones McCoy. The episode in which this ship was featured was an idea I came up with a long time ago just so I could show how I think Kirk and his crew would look at a 24th century starship.
I think it's safe to say that this ship truly never will be forgotten...
