The Aero Spacelines Super Guppy is a large, wide-bodied cargo aircraft that is used for hauling outsize cargo components. It was the successor to the Pregnant Guppy, the first of the Guppy aircraft produced by Aero Spacelines, which in turn was named for its resemblance to a pregnant guppy. Five were built in two variants, both of which were colloquially referred to as the "Super Guppy".
