JOSH-A is a military base on Earth in the series Gundam SEED.


JOint Supreme Headquarters - Alaska, JOSH-A (pronounced Joshua) was the central command center of the Earth Alliance after the fall of Victoria Base. The base was constructed by the two main powers of the Earth Alliance, the Atlantic Federation and the Eurasian Federation and, as its name implies, located in Alaska (specifically inside Norton Sound). The base was designed to withstand anything up to a nuclear attack and as such, is heavily fortified and could only be accessed by gates hidden in the landscape.

On May 5, CE 71, ZAFT launched Operation Spit Break. However, at the last minute, the operation's target was switched to JOSH-A and due to this sudden change, 72 hours elapsed before ZAFT's assault on JOSH-A began.[1] Unbeknownst to ZAFT, the Atlantic Federation had set a trap and secretly installed a Cyclops System under the base after Rau Le Creuset leaked information about the operation. The base was then evacuated of Atlantic Federation personnel, leaving the personnel of the Eurasian Federation (the Atlantic Federation's greatest rival) to defend the base on their own along with the Atlantic Federation's own unwanted forces such as the Archangel (deemed tainted for having Kira Yamato, a Coordinator, among its crew). ZAFT forces were eventually lured into the interior of the base in large numbers, until the Atlantic Federation triggered the Cyclops System, which allowed them to "kill two birds with one stone". The attacking ZAFT force and the Eurasian forces were mostly wiped out, while the base itself was reduced to a smoking crater. This event tilted the inner Earth Alliance's balance of powers mostly towards the Blue Cosmos-controlled Atlantic Federation.

  • JOSH-A is the Cosmic Era's version of the Earth Federation's Jaburo base, however unlike Jaburo, JOSH-A wasn't the main headquarters of the Earth Alliance. Similarly, the JOSH-A base and Jaburo base were both destroyed with superweapons attempting to wipe out opposing forces.
