The First Federation era Dragonfly Class Ship used relatively large amounts of antimatter stored in powerful Penning Traps to achieve high acceleration
The Dragonfly Class ship, developed in Solsys during the First Federation, used relatively large amounts of antimatter in a beamed core propulsion system to achieve high acceleration; it was used as a pursuit ship in anti-piracy operations, as a System Control Ship in the Eridanus League, and on occasion as an interstellar craft for journeys of twenty light years or less.
