The pinnacle of Tau technology, the Hero class was the product of Tau experience during the Damocles Gulf Crusade. The Tau were determined that they should have a ship that could match the Imperial Lunar class. As it became evident, they failed but they did succeed in producing a credible ship of the line.

With its weapon systems crewed largely by Fire Caste warriors the Khas'a'tah has quickly developed a formidable reputation in battle. From its baptism of fire when it hunted down and destroyed no less than three Ork Onslaughts with a single salvo of missiles to its most recent encounter with the Dauntless class cruiser Jarrall's Bane when its Barracudas got inside the Imperial vessels shields and set it ablaze the Khas'a'tah has enjoyed unrivalled success. The principal reason for this is Kor'O Khas'a'tah himself, who, though a member of the air caste was raised in an orbital above Sa'cea and is therefore very familiar with the Fire Caste and their ways. His crew is an excellent example of the two castes working together for the greater good.
