The RM12 powers the Gripen fighter. It is based on the General Electric F404 engine from which it has been developed to single engine safety criteria, higher performance and greater durability. The primary objective during development of the Gripen/RM12 system was to attain the highest
possible operational effectiveness at the most favorable life-cycle cost.
The Gripen's first flight took place 1988 and the aircraft has been in service with the RM12 in the Swedish Air Force since 1997.
