First twin-engine design by this company since World War I, the Morane-Saulnier M.S.700 of 1948 was a sleek, cantilever low-wing monoplane with retractable tricycle landing gear, the cabin accommodating five in either an executive transport or air taxi role. Powered by two Potez 4D-33 inline engines, each of 119kW, the M.S.700 had a maximum speed of 290km/h. It was followed by the M.S.701 with two 134kW Mathis 8G-20s, the larger, six-seat M.S.703 with two 179kW Argus As 10Cs, and the M.S.704, similar to the M.S.703 but with two 164kW Potez 4D-31s. The M.S.703 had a maximum speed of 300km/h, being flown for the first time in 1951. None of the variants was built in quantity, only four being entered on the French civil register.
