The Dassault Super Mystère is a French fighter-bomber and was the first Western European supersonic aircraft to enter mass production.
The Super Mystère represents the final step in evolution which began with the Dassault Ouragan and progressed through the Mystère II/III and Mystère IV.
While earlier Mystère variants could attain supersonic speeds only in a dive, the Super Mystère could exceed the speed of sound in level flight.
This was achieved thanks to the new thin wing with 45° of sweep and the use of an afterburner-equipped turbojet engine.
The first prototype Super Mystère B.1, powered by a Rolls-Royce Avon RA.7R, took to the air on 2 March 1954.
The aircraft broke the sound barrier in level flight the following day.
As the Super Mystère B.2, sometimes known as the SMB.2, the aircraft entered production in 1957.
The production version differed from the prototype by having a more powerful SNECMA Atar 101G engine.
A total of 180 Super Mystère B.2s were built.
In 1958, two Super Mystère B.4 prototypes were built.
Equipped with a new 48° swept wing and a more powerful SNECMA Atar 9B engine, the aircraft were capable of Mach 1.4.
Production never materialized because the faster Dassault Mirage III was entering service.
In 1973, the Israeli Air Force and Honduras Air Force upgraded their Super Mystère B.2s with a non-afterburning version of the Pratt & Whitney J52-P8A and new avionics.
In Israeli service these upgraded SMB.2s were also known as the IAI Sa’ar
