GKN Aerospace has delivered the first upgraded RM12 engine to the Swedish Armed Forces, marking a milestone in the Enhanced Performance (RM12EP) program.
“This first upgraded engine delivery represents an important step forward in enhancing the performance and endurance of the Gripen system. As type certificate holder for the Gripen C/D engine and with a partnership with the Swedish Air Force that spans nearly a century, we are proud to continue supporting Sweden’s operational capability and future readiness," Vice President Governmental Solutions at GKN Aerospace, Stefan Oscarsson, said.
The delivery has followed an earlier order from the Swedish Armed Forces which has been valued at approximately £32 million / SEK 400 million (approx. A $61 million) for performance upgrades across the Gripen C/D engine fleet.
The RM12EP upgrade has included the installation of improved turbine hardware and updated engine control software designed to increase engine thrust and operating efficiency, extend operating time and reduce life‑cycle costs for the JAS 39 Gripen C/D.
All work has been carried out at GKN Aerospace’s facility in Trollhättan, Sweden, where the company is responsible for the development, manufacturing, system support and maintenance of both the RM12 engine powering the Gripen C/D and the RM16 powering the new Gripen E/F.
Key partners for the project were GE and Saab. Additional upgraded engines will be delivered continuously to the customer as planned.
The RM12EP program, launched in 2019 and led by GKN Aerospace, forms part of long-term efforts to ensure the Gripen C/D remains a highly capable and cost‑efficient fighter aircraft.
The upgraded engine will form the foundation for continued operation and maintenance support, for which GKN Aerospace remains responsible.
