Supermarine "Giant"

The Supermarine Giant, also known as the Type 179, was a British monoplane flying boat designed by Supermarine as a large passenger airliner and cancelled before it was completed. It was an all-metal design carried on six Rolls-Royce Buzzard piston engines mounted above the wing, with a crew of seven and room for forty passengers in its day configuration. The keel was laid down in 1931 and the aircraft had been registered as G-ABLE in April 1931, but the project was abandoned in 1932 while the airframe was still under construction. It never flew, and it is one of the large flying boat studies that Supermarine drew up between its Southampton biplanes and the later monoplane flying boats.
