Detailing the development and operational history of the Dassault MD.454 Mystere IV Single-Seat, Jet-Powered Fighter / Fighter-Bomber.  Entry last updated on 2/20/2018. Authored by Staff Writer. Content ©
The Dassault Mystere of 1954, a straightforward, swept-wing development of the earlier Ouragan jet fighter of 1952, was not an outright success and prone to structural failures. As such only 171 were built and these served solely with the French Air Force for their time in the air. More work was needed to bring the swept-wing fighter to a better standard and this resulted in the MD.454 Mystere IV, a refined, much-improved evolution of the series which went on to see considerably more success than its predecessor.

Mystere IV Development
The Mystere IV was more an extension of the Mystere II mark than the Mystere IIC which reached operational service. Engineers worked within the established framework of the Mystere II but were able to apply various structural improvements based on lessons learned from the original project. The result was a prototype, essentially an all-new aircraft despite its Mystere II origins, achieving a first-flight on September 28th, 1952. Such was the speed in bringing this aircraft to the market that it was introduced as soon as April 1953 - the original MD.452 Mystere arrived in 1954 and was soon relegated to a training role and ultimately retired from French Air Force service.

Mystere IV Production
Production of the Mystere IV spanned from 1953 until 1958 and yielded 432 examples (including prototypes). The initial fifty airframes were equipped with the Rolls-Royce "Tay" turbojet and the remainder of the batch followed with the locally-produced Hispano-Suiza "Verdon 350" model turbojet engines, the licensed form of the British Tay.

Mystere IV Walk-Around
In form and function, the Mystere IV held true to its Mystere origins in that it had a circular nose-mounted air intake, low-mounted swept-back wing mainplanes and a retractable tricycle undercarriage. The cockpit was centered ahead of the mainplanes and aft of the nose intake. The tail unit incorporated a single fin with mid-mounted planes. The jet engine exhausted under the fin element in typical fashion. The Verdon engine produced 7,716 lb of thrust and propelled the aircraft to speeds of 690 miles per hour up to a ceiling of 49,200 feet and out to ranges of 570 miles. Rate-of-climb was 7,875 feet-per-minute.

Aboard were 2 x 30mm DEFA cannons and support was given for up to 55 air-to-air rockets held in a retractable ventral pack (just under the cockpit floor). There was also provision for up to 2,200lb of externally-held drop-ordnance across four hardpoints. Drop tanks could be fitted for improved operational ranges.

The Mystere IV in Service
The French Air Force stocked some six squadrons with its new fighter-bomber and some were used in the Suez Crisis of 1956. The service utilized the series into the 1980s before the line was retired in favor of more modern alternatives. French Air Force Mystere IV strength reached 241 examples.

The newly established nation of Israel passed on purchasing the Mystere IIC for the much improved Mystere IV when it committed to twenty-four of the type in 1955. First-deliveries occurred in 1956 and these became the country's first swept-wing designs. Later that year a follow-up order increased fleet strength by thirty-six units. These aircraft were also featured in the Suez Crisis against the Egyptian foe where they undertook both air-to-air and air-to-ground sorties and fared well against the vaunted Mikoyan-Gurevich MiG-15 jet fighter - a contemporary to the Mystere IIC. The Israelis lost one Mystere IV to the enemy's 147 aircraft and this to ground-based fire.

Israeli Mystere iVs soldiered on into 1971 before seeing retirement from frontline duties. Israeli Mystere IV strength reached 110.

India was the only other notable operator of the Mystere IV and a total of 110 examples were delivered. These were purchased in 1957 and were pushed into combat actions in the 1965 war against neighboring Pakistan (Indo-Pak War, the first of two major confrontations between the two parties). The series did well for itself in the war and managed air and ground kills. After the conflict, the Mystere IV fleet was drawn down in 1973 - but not before playing a role in the Indo-Pak War of 1971.

The Mystere IV program involved one prototype and the 421 Mystere IVA production aircraft that following it. The Mystere IVB was a proposed model to feature either the Rolls-Royce Avon turbojet engine or the homegrown SNECMA Atar 101 series. A radar ranging gunfight was also installed and six examples were built in a pre-series form. However, the product was not adopted as the French Air Force focused on the Super Mystere instead (detailed elsewhere on this site).

The Mystere IVN was a proposed two-seat night-fighter development of the IV. This was to carry the American AN/APG-33 radar fit and be powered by the Rolls-Royce Avon while armed through a 55 x 68mm Matra retractable ventral rocket pack. While flying on July 19th, 1954 it was not selected for further development as other mounts stood up to take the role of night hunter.
