The first series example of the Mystere IVA made it's initial flight on 28 May 1954. Following completion of the initial batch of 50 aircraft, the Tay 250A was replaced on the production line by the 7,716 lb st (3,500 kg st) Hispano Suiza Verdon 350. The type entered service in the year 1955, with about 480 aircraft built. They were operational until the 1980s and were also used as a trainer aircraft by the Demonstration squadron Patrouille de France. Just like its predecessor, the Ouragan, the Myst\u00E8re was exported to India (110 new built examples delivered from 1957) and Israel (60 ex-French examples delivered from April 1956)."@en . .
