Osea



"Osea likes to show everything in the Osean continent and the rest of Strangereal downtown. With all of its democratic government, a highly-developed nation, a large population, an extensive infrastructure, a thriving economy and a well-outfitted military force, this one is so strong that it'll be ideal to fear many Coalition bastards out there."

--Su Ji-Hoon, Welcome to Strangereal

Osea, officially known as the Osean Federation, is a large Strangereal country and international superpower located on the Osean continent. Osea encompasses a majority of the continent's western landmass and shares land borders with Belka, Ustio, and Sapin to the east and an unknown country to the south. Its capital, Oured, is located on the tip of Osea's southeastern peninsula near Oured Bay.

Osea is a highly developed country that possesses a large population, an extensive infrastructure, a thriving economy, and a well-outfitted military force. Osea is also considered one of the world's foremost leaders in aeronautics and space exploration development. The country's achievements include the construction of the Strategic Orbital Linear Gun, the Arkbird (a joint program with Yuktobania), and the Arsenal Birds.

By virtue of its world power, Osea held expansionist ideologies and annexed new territories throughout the 20th century. The country's aggressive nature directly resulted in major conflicts such as the Osean War, the Belkan War, and the Usean coup d'état. A rivalry also existed between Osea and Yuktobania, which led to the Strangerealian Cold War in the 1980s and 1990s.

In the 21st century, especially following the election of President Vincent Harling, Osea's expansionism was curtailed and the country diminished its military power to follow a more peaceful foreign policy. Despite the Circum-Pacific War against Yuktobania, which was orchestrated by Belkan extremists as revenge for the Belkan War, this policy of peace continued into the 2010s. The Kingdom of Erusea declared war on the country in 2019 due to a series of terrorist attacks were conducted in Osea by drones.

Osea is the player character's homeland in Ace Combat 5: The Unsung War and an allied country in Ace Combat Zero: The Belkan War. The player will be allied with Osea (to an unknown extent) in Ace Combat 7: Skies Unknown.

In When the Cold Breeze Blows Away, it will be one of the major forces for the Grand Alliance and a member of the Independent States Allied Forces (ISAF).

Soon, it commonly will fight against Yuktobania (only during the USRAC War), the Combine Empire, the Dominion of Cassus, the Kingdom of Khador, North Korea, China, Russia, the Nazi Union, the Redcoat Union, the Irken Empire, the anime teenagers, the Tamagotchis, Nilfgaard, the Romulan Star Empire, the Confederacy of Independent Systems, the Klingon Empire, the Transdimensional Citadel of Ricks, Mordor, the Galactic Empire and the rest of the Coalition of the Red Star during World War III.
