Uganda

The Republic of Uganda is a landlocked nation in equatorial East Africa. Due to being on the equator, Uganda is ideally sited for a spaceport launching payloads into geostationary orbit. As of 2014, this had never been pursued because of political instability in the country, although Uganda was active in the development of Space Law.

By the time of the nuclear apocalypse, the Ugandan Space Initiative was large enough to support one of the worlds 13 manned national space stations.
