The Judgement Cannon was commissioned while the Hand of Artakha was still in power. Due to its nature, the project was kept a strict secret, to the degree that few have even heard of it today. Those that do know guard the knowledge closely. The secret nature of the project was meant to keep the technology from falling into the wrong hands, for fear that it could be redesigned to keep a conflict running, or grant victory to the wrong side. The Order of Mata Nui was rumored to possess at least one of these devices; it is unknown if any are still in operational condition.
