Overview
Named in honor of Jack O'Neill of the Tau'ri, it dwarfs the Prometheus and Ha'tak's. The vessel carries the most advanced weapons used by the Asgard. It has replaced the Bilskirnir-class as the Asgard's main vessel of choice when engaging hostile forces. It possesses incredibly powerful energy weapons, neutrino-ion generators, and five beamers.
