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.

The CFM success story at a glance: more than 30,000 engines produced to date, over 1,600 engines produced annually, a CFM56-powered aircraft takes off somewhere in the world every 2 seconds - and these aircraft carry over 3 billion passengers a year!

LEAP, the successor to the CFM56

Le moteur LEAP-1A a été sélectionné par Airbus pour équiper son avion de nouvelle génération A320 neo. 
Développant une poussée maximale de près de 33 000 livres au décollage, le LEAP-1A doit entrer en service en 2016.

Building on this unprecedented success, Snecma 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, it is now under development by Snecma and GE Aviation. The LEAP offers such outstanding performance versus today's engines that it is already the best-selling engine under development in history, two years before entering revenue service. Airlines and operators from around the world have already placed over 11,500 orders and commitments for LEAP engines, which will power their upcoming Boeing 737 MAX, Airbus A320neo and Comac C919 single-aisle jets. CFM's share of the mainline jet market is set to increase, given current predictions for traffic growth and fleet replacement needs. Requirements in the single-aisle commercial jet segment will double in the next 20 years, which means more than 20,000 new airplanes to be delivered… and billions more passengers for the air transport industry.

Safran is also a player in the business jet market, with the new Silvercrest® engine being developed by Snecma for super-midsize jets. Drawing on state-of-the-art commercial and military engine technologies, this new-generation engine will easily power non-stop Paris-Beijing or Los Angeles-London flights, for instance. The Silvercrest® has already been chosen by Dassault Aviation for its Falcon F5X high-end bizjet.

Safran 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. See the video.
