The company employs around 15,700 people across 35 production sites, offices, and MRO facilities worldwide and files an average of nearly 500 patents each year.

[10] To cope with high demand for the LEAP engine, CFM has duplicated supply sources for 80% of parts and as well as subdivided assembly sites.

[14] It fulfills numerous stringent performance criteria, including a high thrust-to-weight ratio, low fuel consumption across all flight regimes, and a long engine life.

It is of a modular design for ease of construction and maintenance, as well as to enable older engines to be retrofitted with improved subsections upon availability, such as existing M88-2s being upgraded to M88-4E standard.

GE Aviation was involved through its Italian subsidiary Avio Aero, providing the gearbox and the low-pressure turbine.To be certified, a blade-out event has to be extremely improbable, less than once every billion flight hours as its resin-transfer molding (RTM) carbon fiber fan blades will be supported by the in-service LEAP experience.

[32] During December 2019, Safran and MTU announced an agreement to found a 50/50 joint venture to manage the development, production, and after-sales support activities of the new military aero engine intended to power the Future Combat Air System.

[33] In June 2021, Safran presented an updated architecture for its RISE open rotor concept, with a single to 144-156 in (365-396 cm) fan with variable pitch blades forward of a row of static guide vanes, to deliver 30,000lb of thrust (133 kN) with 20% better efficiency than the CFM LEAP.
