The largest firework ever produced was Universe I Part II, exploded for the Lake Toya Festival, Hokkaido, Japan on 15 Jul 1988. The 1,543 pound shell was 54.7 inches in diameter and burst to a diameter of 3,937 feet.
Note:
This was not an aerial shell but a shell that was placed on a floating platform and ignited.
