The RM12 is a derivative of the successful F404 turbofan, developed originally by the U.S. Navy for its Boeing F/A-18 Hornet. GE and Volvo Aero Corporation have developed the RM12 to power the Saab/BAE Systems JAS39 Gripen, a multi-role fighter, attack and reconnaissance aircraft.

Reaktionsmotor 12 (RM12) is a low-bypass afterburning turbofan jet engine developed for the Saab JAS 39 Gripen fighter. A version of the General Electric F404, the RM12 was produced by Volvo Aero (now GKN Aerospace Engine Systems).

The General Electric F404 and F412 are a family of afterburning turbofan engines in the 10,500–19,000 lbf (47–85 kN) class (static thrust). The series is produced by GE Aerospace. Partners include Volvo Aero, which builds the RM12 variant. The F404 was developed into the larger F414 turbofan, as well as the experimental GE36 civil propfan.

Variants/Upgrades RM12. The RM12, developing 18,100 lbst (80.5 kN), equips series-production models of the Gripen. It was developed from General Electric's F404-GE-100. Control systems and materials were changed, and the afterburner's efficiency was significantly improved.

GE and Volvo Aero Corporation have developed simple, modular design is reliable and easy to maintain – the RM12 to power the Saab/BAE Systems JAS39 Gripen, key to high readiness and low cost of ownership.

One of the most versatile engines in its class, GE Aerospace’s F404 engine is a compelling choice for new armed forces applications around the globe. Selected to power the new T-7A Red Hawk advanced jet trainer for the U.S. Air Force, the F404 continues to set the standard for performance, simplicity, and capability aboard a growing range of ...
