The Joint Assault universe is the the first world in the Ace Combat series to mirror to our world.
Joint Assault Universe
The universe has similarities to our reality, with references to events such as the Great Recession. This world also has similarities with Strangereal, such as the existence of airborne fortresses, such as the Spiridus and the Orgoi. Also, original aircraft that existed in Strangereal, such as the XFA-27, also exist in this world. This universe also debuted original aircraft of its own, such as the GAF-1 Varcolac. Which was later brought to the Infinity universe.
