*Based on the theories of Zefram Cochrane, the warp engines of the U.S.S. Enterprise are used to propel the starship through space at speeds greater than the speed of light. The warp engines harness the enormous power generated by matter/anti-matter reactions by focusing the particle stream through a dilithium crystal chamber. Warp speeds are expressed in terms of "factors." Warp Factor One equals the speed of light, while Warp Factor Ten is infinitely fast. On the U.S.S. Enterprise, the warp engines are housed in two large nacelles on struts attached to the stardrive section, behind the primary hull. *Source: Back of card
