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.
Five were built in two variants, both of which were colloquially referred to as the "Super Guppy".

Aero Spacelines Super Guppy

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. Five were built in two variants, both of which were colloquially referred to as the “Super Guppy”.

The Super Guppy is “the only airplane in the world capable of carrying a complete S-IVB stage”, the third stage of the Saturn V rocket.[3] The Super Guppy performed this role several times during the Apollo program.

Design

The first, the Super Guppy, or “SG”, was built directly from the fuselage of a C-97J Turbo Stratocruiser, the military version of the 1950s Boeing 377 Stratocruiser passenger plane. The fuselage was lengthened to 141 feet (43 m), and ballooned out to a maximum inside diameter of 25 ft (7.6 m), the length of the cargo compartment being 94 ft 6 in (28.8 m). The floor of the cargo compartment was still only 8 ft 9 in (2.7 m) wide, as necessitated by the use of the Stratocruiser fuselage

Variants

  • Aero Spacelines B-377-SG Super Guppy, prototype of a much enlarged version of the Guppy using C-97J components, powered by four Pratt & Whitney T-34-P-7WA turbo-prop engines.[1]
  • Aero Spacelines B-377-SGT Super Guppy Turbine (Guppy 201), production version powered by Allison 501-D22C turbo-prop engines, using an enlarged cargo section built from scratch instead of being converted from original C-97J components.

In the early 1970s, the two Super Guppy Turbines were used by Airbus to transport airplane parts from decentralized production facilities to the final assembly plant in Toulouse. In 1982 and 1983, two additional Super Guppy Turbines were built by Union de Transports Aériens Industries in France after Airbus bought the right to produce the aircraft. The four Super Guppies have since been replaced by the Airbus Beluga, capable of carrying twice as much cargo by weight.
