Ace Combat 04 takes place in 2004 on Strangereal's Earth. Five years after, a large asteroid named Ulysses 1994XF04 made impact with the planet, killing many civilians and destabilizing the Usean continent. A large network of eight railguns, Stonehenge, was created to defend the continent from total destruction. In 2003, the Federal Republic of Erusea seized the Stonehenge facility and turned it into an anti-aircraft weapon; the Independent State Allied Forces (ISAF) attempted to destroy Stonehenge, but failed, and were forced to retreat from the Usean mainland to North Point, an island nation to the northeast.The player takes control of Mobius 1 in September 2004, a year after the conflict began, as one of the few ISAF pilots still remaining. Mobius 1 participates in various missions with other ISAF pilots over the next few months in eastern Usea, outside of Stonehenge's range, to defend North Point and weaken Erusea's influence. Erusea attempts to deploy their "invincible" Aegir Fleet to destroy North Point, but ISAF pre-emptively sinks it, giving them an opportunity to perform a counterattack. As ISAF pushes further inland, Stonehenge repeatedly fires on their pilots in an effort to shoot them down. Erusea also deploys Yellow Squadron to the front lines, but Mobius 1 evades them each time they appear.In April 2005, Mobius 1 participates in a second air assault operation to destroy Stonehenge, and single-handedly destroys each railgun. Yellow Squadron appears late to the combat zone, and Mobius 1 shoots down Yellow 4, Yellow 13's closest wingman. The squadron retreats, and ISAF begins a large-scale ground offensive to retake Usea and invade Erusea. ISAF receives intelligence that Erusea is building a new superweapon, Megalith. By the time Mobius 1 assists ISAF's siege on Erusea's capital city, Farbanti (during which he shoots down all of Yellow Squadron), Megalith is completed and begins attacking ISAF. Mobius 1, with the newly-reformed Mobius Squadron, destroys Megalith and brings the war to an end.
