The Hercules flew only once, on November 2, 1947. Its photographs tell a longer story: a designer talking about giant flying boats before the war, an airframe taking shape, and a machine whose preservation required decades of work.
These images span 1938 to the museum era. Four belong to the aircraft’s construction or preservation record, one shows Hughes before the project, and the final view examines the surviving aircraft. Dates and later views are identified individually.

A flying-boat idea before the war
Hughes addressed the National Press Club after his celebrated round-the-world flight. The original caption records him discussing giant flying boats for Atlantic travel. This 1938 appearance predates the Hughes-Kaiser wartime project, but the ambition was already part of his public thinking.

An overhead view records the Hercules during construction. The archive does not provide an exact date, and the photograph is presented here with that uncertainty intact. Wings, fuselage and the surrounding work area give a useful measure of the project’s physical scale.

The Hercules on the water
The completed flying boat sits on the water in this photograph cataloged as circa 1947. It shows the hull and long wing carrying four engines on each side. The image is not presented as proof that the aircraft is airborne: the documented first and only flight came on November 2.

Preparing for a public life
Navy photographer Robert G. Swan photographed the aircraft at Long Beach in March 1982. More than three decades had passed since the flight. Its preservation depended on keeping an enormous, unusual structure intact even though it no longer had an operational role.

A new journey by water
The detached fuselage passed through the Willamette Falls Locks on its way to McMinnville. Moving the aircraft required separating components that had once been designed to function as a single flying machine. This Corps of Engineers record belongs to the preservation journey of 1992, not to the 1947 test.

Four engines beneath one wing
This later museum photograph brings the nose, cockpit and starboard engines into the same frame. It is a view of the surviving aircraft, not a period flight photograph. Preserving the machine allows details that disappear in distant harbor pictures to be examined at close range.
