A ship class in Star Trek, seen most often as the Enterprise D in Star Trek: The Next Generation and Star Trek: Generations.

Replaced the Ambassador Class Starship as the flagship of Starfleet, and was replaced by the Sovereign Class Starship after the destruction of the Enterprise D above Veridian III in ST: Generations.

This class of ship was created to house a huge number of people while not requiring a large number of crewmen; as a result, the crew's families may live aboard. To prevent a large loss of life in an attack, the saucer section of this starship may disconnect from the drive section and retreat while the drive section continues the battle. Armed with a full spread of phaser banks and three photon torpedo tubes.
