The Savoia-Marchetti SM.93 was a dive bomber developed and constructed in Italy beginning in 1943.[1]
Design
The SM.93 featured a wooden, single-engine low-wing monoplane configuration equipped with retractable landing gear. Its fuselage utilized a monocoque design, incorporating a single vertical stabilizer and a low-mounted horizontal tailplane. The two-person crew sat beneath an elongated greenhouse-style canopy; the pilot operated the aircraft from a prone position situated above the rear section of the engine—a Daimler-Benz DB 605A liquid-cooled V12 powerplant—while the gunner and radio operator occupied a conventional rear-facing seat.
The wing structure consisted of three segments supported by two spars: the inner wing panels tapered sharply where they joined outboard of the landing gear mounts, while the outer sections tapered more gently toward rounded tips.[2] Positioning the pilot prone aimed to enhance tolerance against g-force-induced unconsciousness, yet this posture proved uncomfortable during routine flight and severely limited rearward visibility.[1]
Development
The aircraft's initial flight took place on 31 January 1944. By 29 March 1944, the SM.93 had completed sixteen test flights, reaching dive speeds up to 900 kilometres per hour (560 mph), which highlighted its aerodynamic efficiency and low drag characteristics.[1][2]
Operational history
Flight evaluations were conducted under the supervision of the Luftwaffe. Although performance metrics were favorable, the prone pilot position was ultimately deemed unsatisfactory due to discomfort and restricted rearward sightlines. Following the 1943 armistice, the German commission overseeing armament production within the Repubblica Sociale Italiana (RSI) terminated the program.[1][2]
