The R-103 Delphinus #3 is a cutting-edge fighter aircraft designed by Neucom Incorporated.


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.

Game Analysis

Ace Combat 3: Electrosphere

"An all-mighty aircraft that has enhanced power and stability of the Delphinus #2, and the last in the Delphinus series. It possesses impeccable performance in all abilities, including turning, speed, power, and stability. By using two of the Delphinus #2's engines, it was possible to substantially increase its mobility. Additionally, canards were installed near the front, and it can achieve higher agility regardless of the pilot's skill."
