Aero Spacelines 377SGT Guppy 201

Although this Super Guppy is very close in dimensions to the original Super Guppy, the shape of the fuselage and engine nacelles are completely different. The fuselage has a smoother flow more remenisent of the Pregnant Guppy.

The first 377SGT Super Guppy Turbine flew on August 24, 1970. After success with the first of the 377SGTs, Aero Spacelines built a second 377SGT and it flew exactly two years later on August 24, 1972.

Aero Spacelines originally planned to build and operate the MGT and SGT aircraft as they had the PG, SG, and MG previously. It was only after the company got into serious financial trouble that the decision was made to sell the SGT to Airbus Industrie.

I am seeking construction photos in France and operation, photos of all Guppy Types for a book that will be published by McFarland and Company. It is a sequel to my book "The ATL-98 Carvair". The working title is "Volumetric Heavy Lift, Hybrid and Guppy Aircraft." This is a comprehensive review and comparison of Guppy and heavy lift aircraft and includes a section on external cargo transport. A large portion of the manuscript has been completed.
Any photos or anecdotal accounts anyone can offer will be appreciated.

The propeller was a 54H60 Hamilton Standard propeller like the Navy P3 except it had C 130 blades with P3 cuffs so they would match up with P3 type spinner and hub fairings. The front part ofcowlings(The QEC portion) were P3 parts slightly modified for Civil Certification.

This version used Hamilton Standard Propellers that were almost the same as those used on the US Navy P3 patrol aircraft. While employed as a Senior Instructor at the Hamilton Standard Service School facility in Windsor Locks CT,I had the pleasure of training maintenance personel on this system. Great Propellers
