The SNCASE SE.212 Durandal was a French jet and rocket experimental fighter aircraft of the mid-1950s. It was designed by the French aircraft manufacturer SNCASE during the early 1950s, who were keen to exploit the potential advantages of a mixed-power propulsion system. In parallel, as part of a wider effort to re-build French military power and to furnish France with advanced, new domestically-produced designs, the French Air Force sought a supersonic-capable point defence interceptor aircraft with which to equip itself. Accordingly, the resulting design, designated SE.212 Durandal by the company, was at one stage specialised towards its application as a dedicated point-defence interceptor aircraft.
