The Morane-Saulnier M.S.433 was a design for a two-seat training aircraft that would have been based on the M.S.430 and powered by a Gnome-Rhône 7Kfs radial engine.
The M.S.430 was largely based on the single seat M.S.405 fighter, but with an extended fuselage to make room for a second crewman and a 390hp Salmson radial engine. The M.S.433 would have been similar, but with the Gnome-Rhône engine. Plans were then changed and the M.S.433 was cancelled in favour of the M.S.435, which was to be powered by a Gnome-Rhône 9Kdrs engine. This version was ordered into production, but none were completed before the fall of France.
