CFM combines the resources, engineering expertise and product support of two major aircraft engine manufacturers: Snecma (SAFRAN Group) of France, and GE of the U.S. Truly a product of international cooperation, the CFM56 line of six engine models offers unparalleled reliability and cost of ownership. With a thrust range of 18,500 to 34,000 pounds, they're well suited for many commercial and military aircraft. CFM is not an acronym, so it doesn't stand for anything. The company (CFM), and product line (CFM56), got their names by a combination of the two parent companies' commercial engine designations: GE's CF6 and Snecma's M56.
