The largest and oldest of the common fusion torches used by the Avgi, the Arc is derived from an interstellar-class design that was modified and downrated to make it more suitable for interplanetary operations by trading specific impulse for raw thrust. At this scale, the pinch is long enough that it is able to confine the plasma for sufficient time to not only fuse the deuterium into a mix of helium-3 and tritium, but to likewise burn the aforementioned fusion products together with leftover deuterium to release even more energy. This reaction, known as catalyzed D-D fusion, gives the Arc superior fuel efficiency over its smaller cousins.
The magnetic nozzle is designed to support a variety of components that can be slotted in to provide various effects, from injecting additional propellant to improve thrust to tapping energy from the expanding fusion plasma to power a ship's systems.
