The Kalminite Zeta bomb is an untested weapon that the Uranians built before the Battle of Crystilia. According to records long after the war the bomb would have been powerful enoguh to have destroyed an entire quadrant of the galaxy. Quite often refered to by its slang term as Project Judah, after the war the bomb was dismantled and the parts vaporised. The plans however where copied and placed in the Uranian Tech Storehouses. The orginal plans where destroyed.
