Dan Hagedorn, former curator of The Museum of Flight in Seattle, and Amaru Tincopa, both specialists in world and Latin American military aviation, have teamed up to compile this definitive monograph describing the Curtiss Design 75 and one of its major production variants, the USAAC’s P-36, and its many international derivatives. The Design 75 of 1935, as it was initially described by Curtiss, was without doubt a turning point in U.S. fighter design. It incorporated all of the technical advances being favored worldwide and was for Curtiss a huge engineering step forward.
