Aerospace Defense Maintenance, Repair And Overhaul (MRO) Market Global Report 2026

The aerospace defense maintenance, repair and overhaul (MRO) market size has grown strongly in recent years. It will grow from $122.87 billion in 2025 to $133.39 billion in 2026 at a compound annual growth rate (CAGR) of 8.6%. The growth in the historic period can be attributed to increasing global military aircraft fleets, rising aircraft service life, growing defense maintenance budgets, expanding commercial aviation operations, and stringent airworthiness regulations.

The aerospace defense maintenance, repair and overhaul (MRO) market size is expected to see strong growth in the next few years. It will grow to $182.45 billion in 2030 at a compound annual growth rate (CAGR) of 8.1%. The growth in the forecast period can be attributed to increasing procurement of next-generation aircraft, growing demand for depot-level maintenance services, rising investments in fleet readiness programs, expanding modernization of military aviation assets, and increasing outsourcing of aerospace MRO services. Major trends in the forecast period include increasing adoption of lifecycle extension programs, rising demand for fleet modernization services, growing focus on component repair instead of replacement, expanding maintenance support for aging aircraft fleets, and increasing use of integrated maintenance planning solutions.

The growth in commercial aircraft deliveries is expected to drive the growth of the aerospace defense maintenance, repair, and overhaul (MRO) market going forward. Commercial aircraft deliveries refer to the transfer of newly manufactured commercial aircraft from aircraft manufacturers to airlines, leasing companies, or other customers after production, testing, and certification have been completed. The increase in commercial aircraft deliveries is primarily driven by rising global air passenger traffic, as growing demand for air travel encourages airlines to expand and modernize their fleets by acquiring new aircraft to accommodate higher passenger volumes and improve operational efficiency. The growth in commercial aircraft deliveries supports demand for aerospace defense maintenance, repair, and overhaul (MRO) services by expanding the global aircraft fleet and increasing the need for routine maintenance, inspections, repairs, and component overhauls throughout the aircraft lifecycle. For instance, in January 2024, according to Airbus SE, a Netherlands-based aerospace and defense corporation, 735 commercial aircraft were delivered in 2023, representing an 11% increase compared with 2022. Therefore, the growth in commercial aircraft deliveries is driving the growth of the aerospace defense maintenance, repair, and overhaul (MRO) market.

Major companies operating in the aerospace defense maintenance, repair, and overhaul (MRO) market are focusing on developing innovative platforms, such as AI-enabled cloud-based predictive maintenance platforms, to improve asset reliability, reduce unplanned downtime, optimize maintenance scheduling, and enhance operational efficiency across aircraft fleets. AI-enabled cloud-based predictive maintenance platforms are digital systems that use artificial intelligence and cloud computing to analyze real-time equipment data and predict potential failures before they occur, enabling timely maintenance and minimizing downtime. For instance, in April 2024, Honeywell International Inc., a US-based aerospace and industrial technology company, launched Honeywell Forge Performance+ for Aerospace, an innovative cloud-based AI and machine learning platform designed for aircraft operators and MRO providers to improve fleet performance management. The platform aggregates and analyzes operational data from multiple aircraft systems to provide predictive insights, real-time health monitoring, and actionable maintenance recommendations, helping airlines and defense operators reduce unplanned maintenance events, improve operational decision-making, and extend asset life cycles through data-driven maintenance optimization.

In May 2026, AMETEK Inc., a US-based aerospace and industrial technology company, acquired First Aviation Services for an undisclosed amount. Through this acquisition, AMETEK aims to expand its aerospace and defense maintenance, repair, and overhaul capabilities, strengthen its position in mission-critical aviation support services, and increase its scale across military and commercial aircraft platforms. First Aviation Services Inc. is a US-based company that provides aerospace defense maintenance, repair, and overhaul (MRO) services.
