The KB-1 was designed to a US Army Signal Corps specification for a reconnaissance aircraft. The tandem two-seat open cockpit pusher biplane was of conventional design, with a monocoque nacelle of mahogany veneer and twin steel tube booms supporting the tailplane. It had a quad landing gear with Ackerman wheels and "tusks" for ground braking. It also featured safety fuel system, engine interchangeability, and was powered by a crank-started 135 hp Hall-Scott A-5A engine, driving a three-bladed Paragon pusher propeller.
Despite successful demonstration flights by test pilot Bert Acosta over New York, at temperatures as low as -11 °F (-24 °C), no contract was awarded.
