Sud Aviation (SNCASO) S.O. 4050 Vautour

The 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.

Development

In June 1951 the French Armée de l'Air issued a requirement for a jet aircraft capable of acting as a bomber, a low-level attack aircraft, or an all-weather interceptor. SNCASO adapted its existing S.O. 4000 for this purpose, the first prototype S.O. 4050 making its initial flight on 16 October 1952.

Subsequently named Vautour II, the aircraft was built in three versions. It entered service with the AdA in 1958, with the last French aircraft leaving frontline service in 1979. A few soldiered on in various duties into the early 1980s. The Vautour saw no combat in French service, and for much of its AdA service life it was maligned as obsolescent and underpowered. Although a moderately good aircraft when originally produced, it never received sufficiently powerful engines. As an interceptor it was outclassed by the Dassault Mirage III, and as a bomber or attack aircraft its lack of an advanced navigation/attack system was a crippling limitation.

The only export customer for the Vautour was Israel, which purchased 28 for the IDF/AF. The Israeli Vautours also entered service in 1958. They saw combat against Egypt beginning the following year and in a series of actions through the Six Day War and War of Attrition. The Israeli Vautours took part in bombing, strafing and air-to-air engagements. In the Six Day War, over three days Vautours fought repeated combats with Iraqi Air Force fighters while raiding H-3 airfield in Western Iraq. On June 6, 1967, Captain Ben-Zion Zohar scored the type's only aerial victory when he downed an Iraqi Hawker Hunter, although two Vautours fell to the guns of Iraqi Hunters on the following day. In all 15 Vautours were lost . They were retired in 1971 in favor of the A-4 Skyhawk, and the last aircraft left service in March 1972, serving as decoys in the Sinai. The Israelis were pleased with the Vautour's range and versatility, and it was well regarded in Israeli service.

Design

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 or any other modern nav/attack systems, weapons being aimed by the bombardier in a glass nose section with a World War II-vintage Norden bombsight. Both the IIB and IIA were limited to clear-weather day use. The IIN interceptor had some capacity for night and adverse weather thanks to 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, but 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 IIB bombers were converted to IIBR standard for photo recce work. French IIB could carry a single AN-11 or AN-22 nuclear weapon in its internal weapons bay, although the primary carrier of those weapons was the later Dassault Mirage IV. A fleet of 40 Vautour IIBs constituted the original air-based component of the French force de frappe, the Command des Forces Aeriennes Strategique (CFAS) of the French Air Force, established in 1955. They were considered marginal for this strategic bomber role and a requirement for a supersonic replacement was placed soon after, in 1956 (see Dassault Mirage IV).

In response to that same 1956 requirement that produced the Dassault Mirage IV, Sud Aviation proposed a stretched Super Vautour, with a combat radius of 1,700 miles at Mach 0.9.

Variants

  • S.O. 4050-01 : Two-seat all-weather fighter prototype, powered by two 23.5-kN (5,291-lb) Atar 101B turbojet engines. First flew on 16 October 1952. One built.
  • S.O. 4050-02 : Single-seat ground-attack prototype, powered by two 27.6-kN (6,217-lb) Atar 101D turbojet engines. First flew on 16 December 1953. One built.
  • S.O. 4050-03 : Two-seat bomber prototype, powered by two Armstrong Siddeley Sapphire turbojet engines. First flew on 5 December 1954. One built.

The Vautour was produced in three principal variants, which had 90% commonality:

  • IIA: Single-seat, long-range attack aircraft, armed with cannon and bombs (carried internally or on four underwing pylons)
  • IIN: Two-seat, all-weather interceptor with DRAC-25AI or DRAC-32AI radar in nose, pilot and co-pilot in tandem seats, armed with cannon, air-to-air missiles, and (theoretically) unguided rockets. The designation was later changed to II-1N.
  • IIB: Two-seat bomber with glazed nose position for bombardier/observer replacing cannon pack, carrying bombs internally and on underwing pylons.

  • Some IIB aircraft were converted to various specialized roles, principally reconnaissance (IIBR and IIBN), ECM, and eventually target tug (IIB-TT).

    • Production

    Total production was 149 aircraft, divided as follows:

    • Prototypes: 3.
    • Pre-production: 6.
    • IIA: 30 (13 for France, 17 for Israel).
    • IIB: 40 (36 for France, 4 for Israel).
    • IIN: 70 (63 for France, 7 for Israel).

    HELP PAGE

    Why this site?

    Discovery

    This website is dedicated to one's aeronautical passion (which I hope we share) and was realised mainly as an educationnal tool. Knowing that, you'll notice that each new visit brings random topics for the purpose of making new discoveries, some achievements or characters certainly not deserving the oblivion into which they have sometimes fallen.

    By these pages, we also want to pay tribute to all those who gave at one time or another, their lives or health in the name of freedom, aeronautical security or simply our comfort.

    Centralisation

    Internet is full of websites dedicated to aviation, but most are dedicated to subjects or periods that are very limited in space or time. The purpose of this site is to be as general as possible and thus treats all events as well as characters of all stripes and times while putting much emphasis on the most significant achievements.

    The same years saw birth of technologies like photography and cinema, thus permitting illustration of a large part of important aeronautical events from the start. Countless (and sometimes rare) media recently put online by enthousiasts finally give us access to these treasures, but the huge amount of information often makes things a little messy. A centralization effort is obviously most needed at this level.

    All persons who directly or indirectly contributed to the achievement or posting of such documents are here gratefully acknowledged.

    Website layout

    Left menus

    Because of the lack of space on smartphones and small tablets, these menus are hidden. Everything is nevertheless accessible via the main menu option, located between the video and photo sections. This menu is placed there for compatibility reasons with some browsers, which play the videos over the menus.

    "Search" and "Latest" :
    The link "In Titles" restricts the search to the titles of different forms. Use this option if you are looking for a plane, a constructor, a pilot or a particular event that could have been treated as a subject.

    The link "In Stories" will bring you to a search in all texts (the "Story" tab) and will take more time. The search term will appear highlighted in green when opening the corresponding story.

    Would you believe, "Timeline" will show all subjects in chronological order.

    "Random" will reload the entire page with a new random topic.

    The bottom section keeps you abreast of the latest five entries. New topics are added regularly. Don't hesitate to come visit us often : add bookmark.

    Blogs and Comments central section

    Under the photos section comes the comments tabs window :

    You can enter general comments in your own language via one of the two buttons on the left (BLOG EN and BLOG FR). Note that these buttons are accessible regardless of the language to allow some participation in the other language.

    All comments are subject to moderation and will be published only if they comply with the basic rules of decorum, while remaining relevant to the purpose of this site.

    The third tab allows you to enter comments on the shown topic and is bilingual. Personal anecdotes, supplements and other information questions will take place here.

    The "Story" tab shows the explanatory texts. They are most often taken from Wikipedia, a site where we participate regularly.

    The "Data" tab is reserved for list of features and specifications.

    Right menus

    On a smartphone, the lack of space is growing and this menu is moved to the bottom of the page to give priority to videos and pictures.

    The top right icons are links to videos posted by third parties (on their own responsabilities) or by ourselves. The link below these icons will take you to the channel of the one who posted the video. Feel free to suggest other videos if you think they are of some interest (Use the BLOG button or the "Contact" link).
