The final expression of Neucom's famous R-10X aircraft line, the R-103 Delphinus #3 fuses the latest aviation technologies, such as energy weaponry and the COFFIN system, while including substantial upgrades over the previous models, such as a multi-wing airframe that greatly increases its maneuverability and state-of-the-art engines which give it an unprecedented advantage in terms of performance over other aircraft of its age.In the year 2040, the R-103 passed its test phases and mass-production was started. The plane saw action during the Intercorporate War, and proved to be a little superior to other high-end aircraft of its era in some areas, like the F-22C Raptor II. Cynthia Fitzgerald of the NEU replaced her R-102-C with the new model in order to keep her combat edge. As well, the insurgent Ouroboros group fielded black-coloured R-103s, serving as escorts of the group's forward base, the UI-4053 Sphyrna.
