The Morane-Saulnier M.S.251 was a more developed version of the M.S.250 advanced observer trainer. Like the M.S.250 it had a swept-back parasol wing aircraft, with the observer carried in the rear cockpit. As well a number of minor improvements, the M.S.251 received a 240hp Lorraine 7Mc radial engine, slightly more powerful than the Salmson engine used in the original.
