The Hall XFH was an American fighter aircraft built by Hall Aluminum Company. It was the first fighter with a semimonocoque metal fuselage.[1]

Development[edit]

The XFH was designed in 1927 by Charles Hall. It was a single-bay biplane with N-struts for the fabric-covered wings. Its fuselage was made of steel tubing covered in a watertight aluminum skin, enabling it to float if ditched in the ocean. Also for ditching on water or on land, the landing gear could be jettisoned. Power was provided by a Pratt & Whitney Wasp radial engine. Testing in June 1929 showed poor handling characteristics and performance. During one test flight, the upper wing came off the plane. After repairs, the XFH made test flights from an aircraft carrier. Designated XFH by the Bureau of Aeronautics, it was purchased not for active service, but to study new metal construction techniques.[1]
