Alessandro Marchetti (1884–1966) designed the MVT (for "Marchetti-Vickers-Terni"), a single-seat, all-metal biplane with its fuselage suspended between the upper and lower wings.

[1] The MVT was powered by an SPA 6a water-cooled engine rated at 164 kilowatts (220 horsepower) driving a two-bladed propeller, and was armed with two fixed, forward-firing 7.7 millimeter (0.303-inch) Vickers machine guns synchronized to fire through the propeller.

[2] In 1920, Marchetti redesigned the MVT, giving it wings of longer span and splayed interplane bracing struts, a new cabane structure, and a more powerful engine, the SPA 62a rated at 234 kilowatts (285 horsepower).

[2] Experience with S.50 in the 1923 contest led Alessandro Marchetti to design and construct a derivative of the S.50, the SIAI S.52 fighter.
