In the aftermath of the bloody Jovian campaign, many nations concluded that the United Nations Navy was not up to the task to protecting their assets in space - and so went about constructing their own space forces.

In the midst of the resulting national fleets, several countries combined their forces into a singular body - the Unified Space Fleet.
