As I said earlier, this thread has rekindled my interest in the Kfir/Neshr. I once was heavily into aircraft of the Israeli Air Force, and it seems that I may be heading down that road once again!
Anyhoo, to shed a bit more light on the subject of the Kfir, I've done a bit more research than I should have (
) and came up with the following:
In 1966 the Israeli Hey'l Ha'avir ordered fifty French Mirage VJ's to supplement and eventually replace it's seventy Mirage IIIJ's. This sale was invalidated by France with it's June, 1967 embargo of sales of weapons to belligerents in the Six-Day War. Needless to say, the Israeli government was, understandably, not happy. Especially given the fact that the aircraft had already been paid for.
The Israeli civil intelligence branch (Mossad), in collaboration with sympathetic Swiss engineer Alfred Fraunknecht, "borrowed" and duplicated the blueprints of the SNEMCA Atar-9C engine. Likewise, the plans for the Mirage III & V were "obtained" from French sources.
The resulting aircraft, essentially modified copies of the Mirage V (powered by modified copies of the Atar-9), were known as Neshrs. The first Neshr is reported to have flown in 1969 with production examples in service by 1971, with many taking part in the 1973 October War. (As an aside, I mentioned in an earlier post that all South African Atlas Cheetahs were remanufactured Mirages. It seems that at least one Cheetah E may have been a remanufactured Neshr. Also, Argentine Daggers are based on the Neshr.)
Even as the Neshr was in production, it was deemed to be somewhat insufficient and plans to develop it's successor were already well underway. This program was code named "Black Curtain" and culminated in the mating of the GE J 79 with a Neshr airframe. This first aircraft was itself given the code name of "Salvo", with the production aircraft being called the Barak. (One French-built Mirage III airframe was also reported to have been mated with a J 79 serving as a viability testbed.) As far as is known, these aircraft differed from the standard Neshr mainly in the change of powerplant. One squadron of Baraks entered service in 1971 and also took part in the October War of 1973. Although these aircraft are regarded by some to be the original Kfirs, the Barak can be considered the father of the Kfir.
The Kfir was first publicly revealed in 1975, and initially appeared to be a shorter and wider Mirage V. In fact, although derived from the original Mirage III/V designs, these were entirely new-built airframes with many features that were considerably different from the Mirages; shortened & widened rear fuselage to accomodate the J 79, enlarged engine air intakes, a dorsal fin ram air inlet, stronger landing gear, a longer nose, revised cockpit and indigenous avionics. Also, some of the early Kfirs were remanufactured Neshrs with all of the modifications listed above, but retaining some of the physical characteristics of the Neshr such as the nose profile. This has caused much confusion as to what is a Neshr, what is a Barak or what is an early Kfir.
The baseline Kfir was produced in small numbers, most of the 27 built subsequently being upgraded to C1 standard, the most obvious changes being the addition of small-profile canards and small strakes on either side of the nose. The canards greatly enhanced combat manoeuvrability and low speed handling, and the strakes served as compensation for the pitch-up instability caused by the additional lift produced by the canards.
Further upgrading led to the Kfir C2, new features including a dogtooth wing leading-edge, new radar and a multi-mode navigation and weapons delivery system. Also added were larger canards above the air intakes as well as the small strakes on either side of the nose. With the larger canard surfaces present on the C2, extra strengthening of the fuselage and inlet was necessary to compensate for the higher loads and aerodynamic stresses. In those earlier Kfirs which were not yet fitted with adequately strengthened frames, only the aforementioned small canards could be retrofitted. However, many aircraft from the initial production batch received the mods and were later upgraded to C2 standards.
IAI built a total of 185 Kfir C2 single seaters and TC2 two seat trainers, a small number of which have been exported to Colombia, Ecuador and Sri Lanka. The 1980's saw extant C2/TC2's further upgraded to C7 standards (as well as some new airframes) which included advanced (smart) weapons delivery systems. The most recently proposed upgrade was the C10, otherwise known as the Kfir 2000. All Kfirs, from the beginning, were intended to be multi-role combat aircraft.
So, although the Kfir can claim basic design and planform commonality with the Mirage V, it is not a Mirage. It is an entirely different aircraft.
