Description:

    This is the application of the technology of using stored antimatter to propel a spacecraft.  Antimatter rocketry is powerful enough to allow subluminal interstellar spacecraft, and easily powerful enough to launch things into orbit of any planetary body, even a gas giant or a medium density star.  This technology and ramscoop fusion rocketry are the two most powerful subluminal propulsion methods, and ramscoop fusion might not be possible.
    An antimatter propelled spacecraft gets its propulsion from the annihilation of matter with antimatter, possibly adding in extra matter to increase the exhaust momentum (since momentum is mass times velocity, and photons don't weigh much).  As such, there is a substantial ionizing radiation hazard to those in the exhaust direction of one of these rockets (and thus, modest weapons potential of the rocket itself, aside from Antimatter Weapons [[linkey]]).  Antimatter interstellar drive-equipped craft can achieve any sub-light-speed velocity that their fuel supply allows them to achieve and Armor[[linkey]] or Shielding[[linkey]] allow the occupants to survive.  Since these craft react antimatter with matter, they rely on antimatter as fuel and (generally) cannot manufacture it.  The exception to this is Ramscoop/Antimatter hybrid craft.
    This is a difficult task, and early models will have a relatively high probability of disaster.
