Advanced technologies allow billions of passengers to take to the air each year for business or leisure travel. Military aircraft patrol our skies to protect people, and to transport troops, equipment, food and other humanitarian supplies, and more. Both civil and military users expect maximum performance and dispatch reliability. These major challenges facing both civil and military aviation are also an integral part of Safran's strategy, as one of the world's leading aircraft engine manufacturers.

Safran designs, develops and produces a wide range of engines and propulsion systems, plus associated support services, through our companies and partnerships, by calling on our people's unexcelled skills, high-value-added technologies and world-class production facilities. Our engines cover all market segments, from commercial aircraft engines for mainline and regional airplanes, to business jet powerplants and engines for military transport, training, combat, surveillance and in-flight refueling missions.

At Safran, our strategy is built around a shared vision with customers and partners. Back in 1974, Snecma (Safran) and General Electric (GE) created a 50/50 joint company, CFM International, to develop a revolutionary commercial aircraft engine. This French-American partnership proved to be a textbook case in cross-border collaboration, giving rise to the CFM56, the world's best-selling aircraft engine, powerplant of the best-selling Boeing 737 and Airbus A320 single-aisle jet families.

LEAP, the successor to the CFM56

The LEAP® engine was developed by Safran Aircraft Engines and GE through their joint company, CFM International, to power the next generation of single-aisle commercial jets. Combining the best technologies from the two partners, LEAP offers operators exceptional performance while retaining the legendary reliability of the CFM56®. These capabilities have already made the engine a best seller, even before it has entered revenue service.

Building on this unprecedented success, Safran and GE renewed their CFM partnership in 2008, also extending it to include services. The two partners confirmed their commitment to jointly developing a new-generation engine that would offer a significant improvement in terms of performance, fuel consumption and environmental friendliness.

This new engine is the LEAP (Leading Edge Aviation Propulsion)! Successor to the CFM56, the LEAP already powers Boeing 737 MAX, Airbus A320neo and Comac C919 single-aisle jets for airlines and lessors from all over the world. 

Safran Aircraft Engines also power some 20 types of military aircraft in 30 countries. Our engines for the Rafale and Mirage 2000 fighters have become global benchmarks. Safran also supplies the TP400 engine for the Airbus A400M military transport, via the European consortium Europrop International: the TP400 is the most powerful turboprop engine in the West, developing some 11,600 shaft horsepower. We are also a partner in FCAS (Future Combat Air System), a French-British program to develop a new-generation combat drone.
