Lunar Farside Drydocks

The Lunar Farside Drydocks are the location for the majority of the larger D1 fleet vessels, such as the D1 Genesis and D1 Revelation, as well as the other battleships and spacecraft carriers. The Drydocks are in a Lissajous orbit around the L2 Lagrange point, and are therefore hidden from Earth view by the Moon itself. There are large cloaking fields that can be activated to hide it from any non-Galactic spacecraft that may orbit the Moon, so it remains unknown to the bulk of the planet's population.
