The SAI-Ambrosini SS.4 was an Italian fighter prototype developed in the late 1930s but never mass produced. The radical design for its day featured a canard-style wing layout and a 'pusher' propeller. Although intended as an air-superiority interceptor the SS.4 never entered service because the design suffered from numerous faults which caused the prototype to crash-land killing the test pilot.
