and a radar ranging gunsight. Six pre-production aircraft were built but the project was abandoned in favour of the promising Super Mystère. In 1954, French pilot Constantin Rozanoff was killed while doing a low-level flyover of this aircraft. Mystère IVN Dassault also proposed a two-seat all-weather interceptor version called Mystère IVN. The aircraft was equipped with the AN/APG-33 radar in an arrangement similar to North American F-86D Sabre Dog, powered by a Rolls-Royce Avon turbojet, and armed with 55× 68 mm Matra rockets in a retractable belly tray. The first prototype flew on 19 July 1954. AdA eventually decided to purchase Sud Aviation Vautour and F-86K Sabre for the interceptor role but the Mystère IVN prototype continued to fly for several years as a testbed for radar equipment.
