USAF Prometheus
The USAF Atlas was the second Prometheus-class battlecruiser and sister ship of the Prometheus built by XSGCOM under the command of Colonel Lionel Pendergast. It was launched in mid 2004 in time to take part in the Battle of Antarctica. After the battle, the Atlas spent several weeks getting completed, though after the Asgard were saved by XCOM over Orilla, the Atlas and other Earth ships were refitted with various technologies like intergalactic hyperdrives, beaming technology, sensors, and shields.
