North America accounts for the largest share of global military aircraft sustainment demand, according to a chart in the Oliver Wyman Global Military Aircraft Fleet and Sustainment Outlook 2026 to 2036. The exhibit tracks sustainment demand by region in billions of constant 2025 U.S. dollars from 2017 through 2036.

The chart shows total global demand near $150 billion in 2026, rising to roughly $165 billion by 2036. North America makes up close to $66 billion of the 2026 total, or roughly 44 percent, and is forecast to grow at a 1.0 percent compound annual rate. Europe is forecast to grow at 1.1 percent, Asia Pacific at 1.9 percent and the Middle East at 2.3 percent, the fastest of any region.

Oliver Wyman projects that global military MRO demand will grow at an average of 1 percent a year over the next decade, about 10 times faster than in the prior decade. Engine maintenance leads the growth, especially for engines on the F-35 and its F135 powerplant, followed by components such as mission systems and complex avionics.

The firm expects all three depot maintenance segments, covering engines, airframes and components, to expand. Airframe work grows slowest because newer designs need fewer heavy airframe visits. Field maintenance, the largest MRO segment, grows as stealth coatings and software updates add labor.

In the United States, Oliver Wyman expects MRO costs to hold steady in the near term as older fleets retire. Costs rise late in the decade as more complex replacement aircraft enter service in large numbers. The figures cover accessible countries only and exclude price escalation.
