World War III (第三次世界大戦, Daisanji Sekai Taisen?) was the third global military conflict in Earth's history, fought in A.D 2064 between the World Republic Federation and an alliance of opposing nations after a fracturing of views over space-development rights. An initial attack with electromagnetic weapons designed to disable information networks and paralyze urban areas triggered a malfunction in unmanned drone bombers, causing them to launch nuclear missiles at cities.
The chaos that prevailed over the next few hours resulted in the widespread use of weapons of mass destruction in retaliation, devastating the planet's environment and putting the human race in danger of total annihilation. A cease-fire agreement was signed between both sides two weeks later in the interest of preserving mankind, marking an official end to the war.
This conflict, while devastating, was a prelude to mankind's true exploration of the star ocean. After the war in A.D 2065, the governments of Earth united, forming the Greater United Nations, which in turn formed the Universal Science and Technology Administration, an organization determined to preserve humanity and restore Earth's ecosystem. The USTA was also charged with finding and exploring inhabitable planets for human emigration, which resulted in the Space Reconnaissance Force's creation after Professor Trillas Bachtein's successful Warp Drive Experiment in A.D. 2087.
Another experiment—this time in the field of Genetics—was carried out in order to adapt to the now hostile environment: Project Hope was founded circa A.D. 2072 upon the discovery of Muah DNA.
