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. 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. 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 a full-scale assault on JOSH-A codenamed Operation Spitbreak. However, the attack was actually a trap by the Atlantic Federation itself, who had 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. 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.
