The Paris was based upon an earlier proposed trainer aircraft, the MS.755 Fleuret. Following the failure of the French Air Force to select the Fleuret, Morane-Saulnier opted to develop the design into a liaison aircraft and compact business jet. The primary difference between the two designs was the altered seating arrangement, the original side-by-side seating two-seat cockpit was modified to allow for the addition of another row of two seats to accommodate passengers. The Paris retained the flight characteristics of the Fleuret along with the option for installing armaments, which maintained its potential for use as a military trainer as well for civil aviation. On 29 July 1954, the prototype performed the type's maiden flight.
