Aerospace defense MRO market seen reaching $182.45 billion by 2030

The aerospace defense maintenance, repair and overhaul market is projected to grow from $133.39 billion in 2026 to $182.45 billion by 2030, driven by larger military fleets, more commercial aircraft deliveries and rising outsourcing. North America leads today, while Asia-Pacific is expected to grow fastest through the forecast period.

Why it matters: - Aerospace defense maintenance, repair and overhaul is a core support market for military and commercial aircraft readiness. - The sector is expanding as operators keep aircraft in service longer and spend more to maintain availability. - Growth in MRO demand also supports broader aviation capacity as fleets expand and modernize.

What happened: - The market was valued at $122.87 billion in 2025 and is expected to reach $133.39 billion in 2026. - The report projects the market will rise to $182.45 billion by 2030. - The report puts the 2025-2026 growth rate at 8.6% and the 2026-2030 CAGR at 8.1%. - The Business Research Company published the forecast on Oct. 9, 2026, from London. - The report covers aerospace defense MRO activity across military and commercial aircraft.

The details: - Aerospace defense MRO includes scheduled maintenance, emergency repairs, component replacements and system upgrades. - The work is performed across an aircraft’s lifecycle to support airworthiness, performance and regulatory compliance. - Key historical growth drivers include larger global military aircraft fleets, longer aircraft service lives, higher defense maintenance budgets, growth in commercial aviation and stricter airworthiness rules. - Expected future drivers include next-generation aircraft procurement, more depot-level maintenance, higher spending on fleet readiness, military aviation modernization and greater outsourcing of MRO services. - Commercial aircraft deliveries are a major demand driver because each new aircraft adds future maintenance needs. - Airbus reported delivering 735 commercial aircraft in 2023, up 11% from 2022. - The report says the market covers Asia-Pacific, South East Asia, Western Europe, Eastern Europe, North America, South America, the Middle East and Africa. - North America held the largest market share in 2025. - Asia-Pacific is expected to be the fastest-growing region during the forecast period. - The report also includes market attractiveness scoring, TAM analysis, company scoring matrix graphics and tables, Excel-based forecasting dashboards, market hotspots infographics, and updated graphics and tables.

Between the lines: - The forecast points to a market that is less dependent on new aircraft sales than on keeping existing fleets flying longer and at higher utilization. - Faster regional growth in Asia-Pacific suggests fleet expansion and aviation modernization are shifting more maintenance demand outside North America and Western Europe. - Rising outsourcing indicates airlines and defense operators may keep leaning on third-party providers for specialized repairs and depot work.

What's next: - More aircraft deliveries and continued fleet growth should keep MRO demand elevated through 2030. - Defense modernization and readiness spending are likely to support higher-value overhaul and depot services. - The report’s forecast period suggests the next major test will be whether outsourcing and readiness budgets grow as quickly as projected.

The bottom line: - Aerospace defense MRO is on track for steady expansion, with demand tied to fleet size, aircraft age and readiness needs rather than a single growth cycle.
