The Fleuret was designed and built to compete in an order for the French Air Force for a two-seat jet trainer. It was a side-by-side low mid-wing cantilever monoplane with a T-tail and powered by two 800 lbf (3.6kn) Turbomeca Marboré II turbojets. The prototype with French test registration F-ZWRS first flew on 29 January 1953. The aircraft was not ordered with the Air Force buying the Fouga Magister instead and only one Fleuret was built.
The Fleuret II an enlarged four-seat development was designed and produced as the MS.760 Paris.
