The Alpha Site, also known as Alpha Site III, the Third Alpha Site, Alpha III, the Milky Way's Alpha Site, Earth's Alpha Site and many other similar names, is the primary off world base for the Stargate Program in the Milky Way. Like the SGC the main complex is built inside a mountain. It serves as an Advanced Military Outpost and Emergency Fall Back Point, allowing a place for off world teams to gate to if they can't get to Earth. As well it can serve as an evacuation point for Earth.

Located on the planet P4X-650, it is in the Milky Way about 640 light years from Earth. The planet lacks any indigenous intelligence life, despite being vary similar to Earth. It orbits a gas giant and posses at least one moon visible with the naked eye.


In addition to a secure gate room and control center an range of science labs, medical facilities, storage, living quarters, and training facilities exist in the core complex. Additionally mess facilities, exercise facilities and even basic recreations facilities are in place to provide the extended stay of personnel in relative comfort. However being a military complex first larger armories hold weapons for both use in defence of the base, off world operations, and as a weapons cache in the event of the loss of Earth. A large hanger capable of maintaining and servicing F-302s is also part of the complex with a run way outside the hanger doors. Railgun implements have also been added and normally at least one ships maintains position in orbit, or within a few dozen light years.

In recent years several smaller compounds have been built across the planets, including an arctic research station, a beach facility (officially for marine biology study but also for R&R) and a secondary military base capability of supporting an entire regiment if needed. Future expansion is planned to include in Battle Cruiser hanger (not intended for construction) and additional personnel facilities. With Alpha site well on it's way of the first human off earth colony.
