Societe Nationale de Constructions Aeronautiques Du Sud Est SE 2410 Grognard
Designed as a single-seat ground-attack aircraft, the Sud-Est SE.2410 Grognard (Grumbler - a nickname for a soldier of Napoleon's Old Guard) prototype flew for the first time on 30 April 1950. Powered by two 2197kg thrust Hispano-Suiza Nene 101 turbojets mounted one above the other in the fuselage and aspirated via a dorsal inlet, the Grognard I flew as a single-seater with wings swept at 47 degrees.
A second prototype, the SE.2415 Grognard II, flew in February 1945. Both designs suffered from flutter-induced problems. The definitive production version would have been the SE.2418, which was to have been powered by Rolls-Royce Tay turbojets, but the SO Vautour was selected to meet the Armee de l'Air's ground-attack requirement instead.
