Rolls-Royce, Pratt & Whitney, and GE Aerospace have substantial influence over commercial aviation, but they do not dominate in the same way. Rolls-Royce is particularly strong in widebody aircraft; GE Aerospace and its 50/50 CFM International joint venture with Safran Aircraft Engines reach across several aircraft segments; and Pratt & Whitney’s geared turbofan (GTF) serves major single-aisle and regional aircraft families. Their power comes from winning aircraft programs and then supporting engines throughout long service lives—not from a single, directly comparable market-share ranking.
What does it mean to dominate the aircraft engine market?
There is no single statistic that captures an engine maker’s influence. Installed engines, aircraft-program selections, new orders, deliveries, flying hours, and service activity measure different things. A large installed fleet can signal a broad service obligation; an order count reflects demand for a particular company’s products; neither, on its own, establishes share of the entire global market.
The available figures are also reported by the companies themselves and use different units and scopes. Rolls-Royce reports engine counts and widebody shares; GE Aerospace reports an installed base spanning its Commercial Engines & Services business and CFM International; RTX reports aircraft powered by Pratt & Whitney GTF engines. These figures show scale in context, not a like-for-like ranking.
Where the three companies compete
Rolls-Royce: a strong widebody position
Rolls-Royce’s clearest position in the reported figures is in widebody aircraft. In its 2025 annual report, the company said it powered four out of five in-production widebody aircraft. It reported a 38% share of the installed widebody base at year-end 2025, up from 34% at year-end 2022. Rolls-Royce also said its engines accounted for more than 50% of new widebody engine deliveries over the preceding three years. Those are company-reported widebody figures, not a share of all commercial engines.

GE Aerospace and CFM: reach across aircraft segments
GE Aerospace’s reach spans widebody, narrowbody, and regional aircraft through Commercial Engines & Services and CFM International. CFM is a 50/50 joint venture with Safran Aircraft Engines, so its business should not be described as exclusively GE’s. GE’s 2025 annual report put the combined reported scope at approximately 50,000 installed engines and said the businesses powered nearly three out of every four commercial flights. Both are GE-reported figures, not independently measured market shares.
CFM’s LEAP engine competes with Pratt & Whitney’s GTF on the Airbus A320neo family. Airbus lists the LEAP-1A and GTF as engine options for that family. This is competition at the aircraft-program level; it does not mean an airline can freely swap one engine type for another after delivery.

Pratt & Whitney: GTF applications in single-aisle and regional aircraft
Pratt & Whitney lists the A320neo family, Airbus A220, and Embraer E-Jets E2 as GTF applications. RTX reported that more than 2,600 aircraft across those three platforms and over 90 operators were powered by GTF at year-end 2025. That is an aircraft count, not an engine count or a directly comparable share of the installed base reported by Rolls-Royce or GE.
What the reported scale figures show—and what they do not
The table puts key company-reported figures side by side while preserving what each one measures. The counts are not interchangeable: a widebody installed-base percentage, an installed-engine count across segments, and an aircraft count describe different populations.

The installed fleet matters because each engine in service requires some combination of spare capacity, parts, technical support, maintenance, and overhaul over time. But the figures above cannot establish which company has the greatest total revenue, profit, or market share: they have different denominators, and the sources do not provide a consistently defined independent comparison.
How aircraft-program wins create influence
An engine maker’s reach is shaped by airframe manufacturers’ program decisions and by certification for a particular aircraft-engine combination. Winning a selection can connect an engine family to years of aircraft production and subsequent support needs. Competing on the same program can also mean that an aircraft family has alternatives without making the engines interchangeable in service.

Even when not in motion, it is an impressive machine to see.
- Excellent Learning Activity: This kit is not recommended for unsupervised children under the age of 14, due to its small parts. However, it provides a great opportunity for adults to spend time with children. The child will learn to understand and follow illustrated instructions, manipulate parts and basic tools, and to know the accomplishment of a job well-done. It fosters an appreciation for the ingenuity in today’s technology as well as the need for it in coming generations.
The Airbus A320neo illustrates the scale of the opportunity, but its aircraft figures should not be mistaken for engine-maker statistics. Airbus’s FY2025 report listed 11,529 firm orders and 4,372 deliveries for the A320neo family through the end of 2025. Airbus also reported that the family represented approximately 60% of the single-aisle backlog compared with the 737 MAX family. These are airframe-family order and delivery figures, not a division of engine orders between CFM and Pratt & Whitney.

Orders and deliveries are useful signals of demand, but they have different meanings. Orders may remain in a book for years; deliveries record engines handed over during a period. Neither should be compared with another company’s installed fleet as if the values measured the same thing.

Rolls-Royce orders and flying hours
Rolls-Royce reported 638 large-engine orders in 2025 and a large-engine order book of 2,207 at year-end. It also reported that large-engine flying hours had reached 111% of their 2019 level. The order figures concern Rolls-Royce large engines, while the flying-hours comparison describes activity against a 2019 baseline; none establishes the company’s share of all aircraft-engine orders or flights.
GE and CFM LEAP deliveries
GE Aerospace reported record CFM LEAP deliveries in 2025, up 28% year over year. It also said the LEAP-1A reverse bleed system had been installed on 50% of that fleet by year-end. These are GE-reported production and upgrade figures, not an overall market-share measure.
Why the installed fleet matters financially
Aircraft engines are long-lived, technically complex assets. Their commercial value extends beyond the initial sale to the work and support needed while they operate: maintenance visits, parts availability, spare engines, technical data, and service agreements. A large fleet can therefore create ongoing service activity as well as a continuing operational obligation.
Rolls-Royce’s 2025 reporting said Civil Aerospace depends substantially on aftermarket performance and long-term service agreements (LTSAs). For that year, it reported 20.0 million LTSA engine flying hours and 1,440 total LTSA shop visits. These are Rolls-Royce service metrics; without matched measures for GE and Pratt & Whitney, they cannot be used to rank the three companies’ service businesses.

Quick Recap
How to assess claims of market leadership
- Check the segment. A widebody share does not describe narrowbody or regional aircraft, and an engine family’s presence on selected aircraft programs does not establish dominance across all aviation.
- Check the unit and denominator. Engines, aircraft, flights, orders, deliveries, and shop visits are not substitutes for one another.
- Check the reporting period and attribution. The figures here come from 2025 company or Airbus reporting and should be read as attributed claims, not as an independent, harmonized league table.
- Separate airframe demand from engine demand. Airbus backlog and delivery totals describe aircraft families, not engine manufacturers’ market shares.
- Be cautious with performance comparisons. The figures reviewed do not provide a matched independent comparison of lifetime cost, reliability, or service-contract economics across Rolls-Royce, Pratt & Whitney, and GE. Claims about fuel efficiency or time on wing require comparable baselines and test conditions.
