The Mirage 4000 fighter jet is an enlarged version of the original Mirage 2000, designed to accommodate two M53 - P2 engines. It features a canard wing layout and adopts an all - metal semi - monocoque structure. The door - type airbrakes are located above the air intakes on both sides of the fuselage and above the leading edges of the wings. The fuselage, rudder, elevons, wings, vertical tail, and fixed forward wings all extensively use boron and carbon fiber composite materials. It is the world's first fighter jet to use all - composite materials and a vertical tail with built - in fuel tanks. The Mirage 4000 fighter jet was independently developed by the French company Dassault starting in 1975 and made its maiden flight on March 9, 1979. During the test flights, its performance was shown to be fully comparable to that of the F - 15. However, due to reasons such as the high procurement unit price, insufficient government orders, and poor export prospects, the production plan was aborted. Eventually, in 1995, it was transported to Paris and became a permane：nt exhibit at the Le Bourget Museum.
