This model of the fictional starship Enterprise was used in the weekly hour-long "Star Trek" TV show (NBC-TV), which aired from September 1966 until June 1969. Despite its short initial run (only three seasons), Star Trek became one of the most influential shows in the history of television. In the television show, the Enterprise traveled at speeds measured in multiples of the speed of light using warp drives, a propulsion concept extrapolated from supersonic flight to imagine faster-than-light travel. The fictional ship grossed 190,000 tons, and measured 947 feet long and 417 feet in diameter. The saucer-shaped hull included 11 decks, and had a crew complement of 430.
