Boeing Model 320

The Boeing Model 320 was a late 1930s project by Boeing for a giant maritime patrol flying boat. Its design featured a very large twin-hulled flying boat, with the crew of eight seated in a nacelle in the wing center section. The recorded specification gives a wingspan of 200 feet, a length of 116 feet and a gross weight of 134,000 pounds, powered by six Wright R-2600 Twin Cyclone engines of 1,200 horsepower each. It remained a design project and no aircraft was built. The only source consulted for it is brief and states no date more precise than the late 1930s, no first flight, no production and no service history, so those are left unrecorded here rather than guessed.
