USS Valiant (NCC-74210)

The USS Valiant (NCC-74210) was a Defiant-class starship in service in the late 24th century.

The Valiant was assigned as a training ship for the elite cadet corps Red Squadron. During the training cruise mission, the Dominion War broke out and the ship was trapped behind enemy lines. During the attempt to return to Federation territory, the Valiant was attacked by a Cardassian battle cruiser and all the regular officers, including the captain, were killed or critically wounded, leaving the cadets in command.

After collecting detailed intelligence concerning a previously unknown Jem'Hadar battleship, the crew attempted to destroy the vessel. In the conflict, the Valiant was quickly destroyed and only three cadets survived the battle. (DS9 episode: "Valiant")
