Strangereal is an alternate Earth which serves as the setting for almost every title in the Ace Combat series, including Ace Combat 2 through Ace Combat 6 as well as Ace Combat X and Ace Combat Zero. Its geography is roughly similar to that of Earth, featuring Antarctica, and an Atlantic and Pacific Ocean. Nations on Strangereal have similar political systems to Earth's countries and many of the wars on Strangereal are similar to those on Earth's.
Strangereal developed in a similar way to Earth, going through a dark age, industrial age, etc.
Ulysses 1994XF04 Asteroid
The major point of divergence from Earth, the Ulysses asteroid was discovered in 1994. It was large asteroid that was on course to hit Strangereal. This asteroid will be the catalyst for many of the wars across Strangereal.
The Belkan War 1995
After years of building military might, the nation of Belka suddenly invades its neighbors including the Republic of Ustio. With their air force virtually wiped out and their capital taken, Ustio turns to mercenaries to retake their country. One of these mercenaries was the legendary "Demon Lord of the Round Table". In the waning days of the war, Belka, unwilling to be defeated, set off seven nuclear bombs on their own cities. This incident became known as "The Seven Pillars of Belka". After the war, Osea and Yuktobania, allies during the Belkan War, plunge into a Cold War with each other. Portrayed in Ace Combat Zero. Referenced in Ace Combat 5.
Projects are underway by various nations to protect Strangereal from the Ulysses Asteroid. On the Usean continent, the Stonehenge Turret Network (STN) was created as a joint venture between nations on the Usean continent. The country of Erusea, also on the Usean continent, secretly builds their Megalith defense system. Meanwhile on the Anean Continent, the Federal Republic of Estovakia commences building the Chandelier, the largest railgun in history.

Fragments from the asteroid continue to rain on Strangereal for several years.

Ace Combat titles not in Strangereal
- Ace Combat: Joint Assault, despite its X2 title in the Japanese version, is not a continuation of Ace Combat X. Rather it is the first Ace Combat game to take place in the real world.
- Ace Combat: Assault Horizon is the first console-based Ace Combat game to follow up on this trend as it trailed on the successes of the popular Modern Warfare series of games.
- The original Air Combat (known as Ace Combat in Japan, and released as Air Combat in the West) takes place on an entirely different world.
- The free to play game Ace Combat Infinity tries to combine the Strangereal setting with the real world, making the discovery of the Ulysses asteroid in 1994 the point at which a new time line is created. Up until the catastrophic impact in 1999 the nations are all as in the real world, but after the devastation refugees form new countries.
