The Halt of Centrian Air Supremacy. The MT9 were the best fighter planes of that era, but journalists unveiled what made it so good. Centria used a very powerful fuel, but the fuel is a carcinogen and basically put an expiration date to any that handled it. This caused a huge backlash and lead to the Abolishment of the whole 119 MT9's that were currently on service. Due to this, Centria's enemies smell blood and they needed something to protect their country for long enough to deter any potential air attacks. The MT10 was developed to intercept high flying enemy bombers that tried to test Centria's relatively weak Air Dominance. It worked alongside the converted attack aircraft A-F 3 which functioned as the temporary leading fighter of the age. This deterred any attacks until the release of the MT11.
