03/31/2012. Evolved in parallel with the SM.91 to meet the 1941 requirement for a two-seat multi-role fighter, the SM.92 retained the basic wing and tail surfaces, and a similar starboard tailboom, and was also powered by two 1,290 hp Daimler-Benz DB 605A-1 engines. By comparison with the SM.91, however, the central fuselage nacelle was eliminated and tandem accommodation for the crew members provided in the port boom.
The proposed armament of the SM.92 consisted of two 0.787 in (20 mm) cannon in the wing centre section, a similar weapon mounted in the starboard engine, two 0.50 in (12.7 mm) machineguns beneath each engine and one 0.50 in (12.7 mm) gun firing aft from a remotely-controlled barbette on the tailplane (site files).
The sole prototype of the SM.92 was flown under German auspices (but carrying an Italian s/n !) on November 12, 1943, and although it was anticipated that the substantial reduction in drag resulting from the elimination of the central fuselage nacelle would result in an exceptional performance, little flight testing was undertaken.
