Warp drive is the primary propulsion system used by most faster-than-light interstellar spacecraft.
Federation starships employ the controlled annihilation of matter (deuterium) and antimatter (antideuterium), regulated by dilithium crystals. This produces highly energetic plasma, called electro-plasma, which is channeled by magnetic conduits through the power transfer conduits. The warp plasma is funneled to plasma injectors into a series of warp field coils found in the nacelles. These coils generate a warp field. This warp field is a subspace bubble that envelops the starship, distorting the local space-time continuum and moving the starship at velocities that exceed the speed of light. These velocities are referred to as warp factors.
