Rhea Base, also known as the Saturn Base was a military base commanded by the Russians and located on the Saturian moon Rhea.
Rhea Base was established by the Earth Space Defense sometime after June 2013. It was designed to be the most outermost point in the ESD's defense network. As of 2016, Rhea was currently under construction.
In July 1, 2016, Rhea Base was destroyed along with the moon and most of Saturn's rings when a wormhole opened near it created by the Harvester mothership.
