Aircraft Turbofan Engine Market Aircraft Turbofan Engine Market Outlook:
Aircraft Turbofan Engine Market size was valued at USD 3.7 billion in 2025 and is projected to reach USD 7.9 billion by the end of 2035, rising at a CAGR of 7.7% during the forecast period, i.e., 2026-2035. In 2026, the industry size of aircraft turbofan engine is estimated at USD 4.1 billion.
The demand for the aircraft turbofan engine market is primarily driven by the sustained fleet growth in the commercial aviation, ongoing replacement of the aging narrow-body aircraft, and regulatory pressures to improve the fuel efficiency and emissions performance. The report from the U.S. Department of Transportation data in March 2023 reported that the airline passenger enplanements in the U.S. are surging, and in 2022, it has accounted for 853 million. This data indicates the higher aircraft utilization and a recovery toward long-term traffic growth trends. Further, the fleet expansion directly supports the long-term procurement of the turbofan engines for the original equipment installation and for the aftermarket services. The FAA further notes that the U.S. air carrier fleet is expected to rise from 4,829 to 6,854 by 2045, sustaining utilization rates that increase engine maintenance, repair, and overhaul (MRO) demand.
Further, the aircraft turbofan engine market’s financial structure is heavily weighted toward the aftermarket, where maintenance, repair, and overhaul services generate a substantial and recurring revenue stream. This is linked directly to the operational lifecycle of an installed engine base that numbers in the tens of thousands worldwide. The International Air Transport Association notes that the MRO spending represents a critical cost center for the airlines, with the engine-related work constituting the major portion. The industry health is closely tied to the airline's profitability and traffic recovery. For instance, the IATA data in January 2024 indicates that the global revenue passenger kilometers accounted for 94.1% in 2023. This report indicates a strong rebound in engine utilization and associated service needs. This recovery supports both OEM production rates for new engines and sustained aftermarket activity, though the sector remains susceptible to macroeconomic cycles and supply chain constraints.
