Savoia-Marchetti S.M.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 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. But the aircraft suffered from various difficulties and never equalled the brilliant performance of its predecessor.

The engine section says 2 x 746kW Piaggio P.XI piston radials, but this looks like a trimotor to me- am I missing something?
