In 1961, Jean Délémontez designed a two-seat light aircraft for the Société Aeronautique Normande (SAN) at Bernay in Normandy to replace his earlier Jodel D.11, which SAN (amongst other manufacturers) were building to meet a requirement for aircraft to equip flying clubs subsidised by the French government.

Délémontez based the new design on his three–four seat Jodel Ambassadeur, (also being built by SAN), with a reduced span wing and shorter fuselage.

[2][3] The new aircraft, the D.150 Mascaret - named after a tidal bore[3] first flew on 2 June 1962, production beginning in 1963.

[2] Like all the light aircraft that Délémontez designed under the Jodel and Robin names, the D.150 is a low-winged monoplane of wooden construction, with distinctive upturned outer wings.

[3][5] [1]Plans for homebuilt construction of the Mascaret remain available, over 100 having been built, including completion of an unfinished factory airframe.
