The USS Excelsior was designed by Industrial Light and Magic`s Bill George for Star Trek III: The Search for Spock. It appears in subsequent films, and the model was re-used for other ships in episodes of Star Trek: The Next Generation and Star Trek: Deep Space Nine, as well as the finale of Star Trek: Voyager.
