The Morane-Saulnier MoS-121, also known as the Morane-Saulnier MS.121 was a French fighter prototype of the 1920s. It was Morane-Saulnier's first fighter design after World War I.
As a direct result of concern over the escalating cost of fighter manufacture, the French government and air force instituted a program for chasseurs légers or 'light fighters' in 1926. This was unofficially known as the 'Jockey' program, and it envisaged the use of moderate guns, minimal equipment and small amounts of ammunition. Emphasis was placed on climb rate, endurance and a ceiling (high for the time) of 8000 metres. To meet this requirement, Morane-Saulnier designed the MoS-121, renamed the MS 121 in 1927, as a single-seat parasol monoplane of mixed construction.
After flying for the first time in mid-1927, it proved underpowered and incapable of climbing easily and was discarded in favour of the Morane-Saulnier MS.221.

The Morane-Saulnier M.S.406 is a French fighter aircraft developed and manufactured by Morane-Saulnier starting in 1938. It was France's most numerous fighter during the Second World War and one of only two French designs to exceed 1,000 in number. At the beginning of the war, it was one of only two French-built aircraft capable of 400 km/h (250 mph) – the other being the Potez 630.
