- Sun Tzu(destroyed)
The three Tau'ri ships that attempted to retake Atlantis were captured and refitted with Alterran technology, making them the most powerful of all 304s in existence. To date they have been used by Lantean personnel on non-combat heavy missions, mostly reconnaissance and transport, but their armament is considerable should they be called upon for fire support.
Within the Tau'ri, the United States of America is the sole producer of the 304 design, given that nation's superior industrial base. All 304s have been built by the US, then sold/traded to other nations, though currently both Russia and China are in the process of upgrading their small scale shipyards in order to be able to produce ships of this size.
Russia and China both purchased a single 304 from the United States, and the United Kingdom was in the process of doing so when the fallout over the stargate transfer arose. That ship was later finished and kept by the US (Revere), however one ship remains in non-US Tau'ri hands.
