Sud Aviation Vautour

The Sud-Ouest Aviation (SNCASO) S.O. 4050 Vautour II was a French bomber, interceptor, and attack aircraft used by the Armée de l'Air (AdA). Later, 28 of these aircraft were used by the Israeli Air Force. Vautour is the French word for vulture.

The Vautour was a shoulder-wing monoplane with a 35° swept wing and a "flying" tail. Two SNECMA Atar 101 turbojet engines were carried in pods in the wings. It had bicycle-type landing gear, with the main units in the fore and aft fuselage and smaller stabilizing gear in the engine pods. The central fuselage carried a large 5.0 meter (16 ft 5 in) weapons bay and substantial internal fuel tankage.

The IIB bomber lacked radar and other modern navigation and attack systems, armaments were aimed by a bombardier housed in a glass nose section of the aircraft with the aid of a World War II-vintage Norden bombsight. Both the IIB and IIA were limited to clear-weather operations in daylight only. The IIN interceptor had some capacity for night and adverse weather though the use of its radar. In Israeli service, where the weather was generally favorable and daylight missions commonplace, the Vautour's lack of advanced targeting and navigation equipment was not a crippling limitation; however, in Europe it was considered a major disadvantage. As a result, the French AdA did not use the single-seat IIA in a frontline capacity, and most of its IIB bombers were quickly converted to IIBR standard to perform photo reconnaissance missions instead.

In French service, the Vantour IIB could carry either a single AN-11 or AN-22 nuclear weapon in its internal weapons bay; although the primary carrier of those weapons would the Dassault Mirage IV, which would later replace the IIB. A fleet of 40 Vautour IIBs constituted the original air-based component of the French force de frappe, the Commandement des Forces Aeriennes Strategique (CFAS) of the French Air Force, established in 1955. Their performance were considered marginal for the strategic bomber role; thus, a requirement for a supersonic replacement aircraft was issued only a year later in 1956. The 1956 requirement would ultimately result in the selection and manufacturing of the Dassault Mirage IV bomber; Sud Aviation had also responded to the requirement with a proposal for a stretched Super Vautour. This unbuilt variant would have had a combat radius of 1,700 miles while travelling at a speed of Mach 0.9.
