Naquadria bombs were first developed by the nation of Kelowna on the planet that would later come to be known as Langara. Among those scientists involved in its development was Jonas Quinn. The Kelownans were developing it as a defensive weapon to discourage attacks by their rival powers, the Andari Federation and Tirania Confederacy, despite warnings from their scientists and SG-1. They eventually used it when their defeat seemed imminent. Taken aback by the power of the device, all three nations agreed to a cease-fire, eventually resulting in a united planetary government.
