The Pegasus engine entered service in 1969 powering the Harrier aircraft and has been progressively developed. The operational background of the Harrier/AV8 family of aircraft was used to define a demonstrator program primarily aimed at improving performance. The XG15 demonstrator program for the Pegasus 11-61 was successfully completed in 1987 followed by durability demonstration in early 1988. The results formed the basis of the improved F402-RR-408 engine offering reduced life cycle costs at higher thrust according to prevailing operational requirements. The production engine validation test program commenced with an engine roll out in Jun. 1988, flight testing commencing at Bristol (United Kingdom) one year later with completion due in May 1990 at the same time as commencement of production engine delivery. A summary of the program and technical arisings is given.
