Sub-light engines used in spacecraft design range from traditional chemical engines and gas thrusters to directed fusion and anti-matter decay. In general engines are defined by the power required to start them, usually notated by the output of the singularity required if applicable, and the available peak thrust, measured in newtons and typically notated as Giganewtons (GiN) or Meganewtons (MiN) when dealing with the thrust produced by interplanetary engines.
Fusion booster designed by Core Corp for use as a primary sublight engine on corvette to frigate mass ships. Also used in cluster thrust powerplants such as the Core Corp Type R Fusion Blossom, which groups 7 Type R boosters into a single engine module. Has an extremely high thrust-to-mass ratio of 51.43 GpT (GiNs-per-ton). Power requirements fall within draw specifications for an FSpec battery for starting the reaction from cold reaction mass, requires supplemental power within spec for an ESpec battery for ongoing use. At max power output produces upwards of 360 GiNs of forward thrust, depending on the mass of the fusible material.
