Savoia-Marchetti SM.84


When it was realized that the S.79 could no longer measure up to foreign medium bombers, SIAI Marchetti designed a version initially called the SM.79bis and then SM.84. With respect to the S.79, the 1940 SM.84 featured a different and more rational internal fuselage design and had twin fins to improve the gunner's field of fire to the rear. The aircraft suffered from various difficulties and never equalled the performance of its predecessor.
