Supermarine "Giant"

The Supermarine Type 179 "Giant" was a British monoplane flying boat developed by Supermarine but cancelled before completion.

Design and development

The Type 179 was an all-metal monoplane flying-boat powered by six Rolls-Royce Buzzard piston engines mounted above the wing. It was to have a crew of seven and room for 40 passengers in a day configuration. The keel was laid down in 1931 and the aircraft was under construction when the project was abandoned in 1932. The aircraft had been registered G-ABLE in April 1931.
