*Due to the tactical ineffectiveness of phasers at warp speeds, photon torpedoes were developed as an alternate defensive weapon. Photon torpedoes are typically elongated elliptical tubes carrying thousands of minute packets of matter and antimatter separated by magnetic fields. On detonation, the magnetic fields are collapsed, forcing the materials together and resulting in an explosive release of energy. There are two photon torpedo launchers on the U.S.S. Enterprise, located at the fore and aft of the Secondary Hull. *Source: Back of card
