Dassault Mirage 4000

Intended as a multi-role fighter, the private venture Mirage 4000 prototype was originally known as the Super Mirage 4000.
Powered initially by two SNECMA M53-2 turbofans with afterburning thrust of 8500kg, the Mirage 4000 introduced extensive use of boron and carbonfibre composites for structures, and computer-derived aerodynamics and a fly-by-wire active control system making possible a rearward CG. Built-in armament consisted of two 30mm cannon and external ordnance loads in excess of 8000kg could be distributed between 11 external stations.
First flown on 9 March 1979, the Mirage 4000 achieved Mach=1.6 during its first flight and Mach=2.2 five weeks later, on 11 April, during its sixth flight.
The single prototype was re-engined with M53-5 turbofans with afterburning thrust of 8790kg during the course of its flight test programme. No production contract was placed for the Mirage 4000, but in 1986, the prototype was re-engined with M53-P2 engines and participated in the Rafale programme.
