Super Robot Wars: Neo Generation
One Year War
The One Year War was the conflict between the Earth Federation and Principality of Zeon that lasted from January 3, UC 0079 to January 1, UC 0080. This war is the most destructive conflict to occur in history to this point and nearly resulted in the extinction of mankind. It also saw the beginning of the use of mobile suits as a widespread weapon of war. The conclusion of the war came as a result of the arrival of ASS-1, later known as the SDF-1 Macross, which severely damaged the Federation and Zeon fleets.
