Earth Alliance Macedon Class Battleship Macedon Class History The Macedon class was built from the unused plans for the Beta Model Medusa class battleship. It was heavily modified, however, and made use of the readily available Omega type of mounts and weapons. The ship was centered around a heavy particle cannon. No ships of this design were ever completed. (Note: This is one of the designs that I have no idea who the creator was) Macedon Class (Alpha Model) SCS
