Aerospace's LEAP Engine Deliveries Jumped 41% This Year. Here's Why Boeing and Airbus Both Need That Number to Keep Climbing.

CFM International, the GE–Safran joint venture that builds the LEAP engine, says it delivered 41% more LEAP engines in the first half of 2026 than in the first half of 2025. The ramp-up follows a prior period when supply-chain bottlenecks disrupted deliveries. The timing matters for both Boeing and Airbus because LEAP-powered aircraft include Boeing’s 737 MAX and the Airbus A320neo family. Boeing has 4,381 firm 737 MAX orders and production at 47 per month, equating to about 7.8 years at current output. Airbus has roughly 7,500 A320s against a goal of at least 70 per month by end-2027, or nearly nine years—so clearing backlogs depends on more engine supply.
