Aerospace And Defense MRO Market Growth & Trends

The global aerospace and defense MRO market size is expected to reach USD 187.3 billion by 2030, registering a CAGR of 5.6% from 2025 to 2030, according to a new report by Grand View Research, Inc. The growth of the aerospace and defense MRO industry is underpinned by expansions of aircraft fleets, rapid urbanization in emerging economies, an increased number of tourists worldwide, and the penetration of low-cost carriers (LCC).

The increasing defense expenditure of emerging economies such as China and India is driving investments in the modernization of equipment deployed in existing aircraft, primarily by incorporating them with new and sophisticated technologies. The rise in air passengers in commercial aircraft and freight traffic worldwide has led to a surge in aircraft fleet utilization, thereby augmenting the need for aircraft MRO services.

OEM and global third-party MRO companies operating have adopted advanced predictive and preventive aircraft maintenance technologies to digitize and automate their airframe maintenance activities to enhance the overall efficiency of the maintenance processes. The deployment of advanced technologies such as artificial intelligence and machine learning is expected to provide opportunities for firms to compete at the global level and reduce MRO expenses.

There is a presence of a large number of players with various MRO capabilities offering services both globally and regionally. The leading players are focusing on maintaining strategic relationships with aftermarket suppliers of aircraft parts to ensure uninterrupted MRO services. Moreover, declining market growth, leveling off outsourcing, and rising number of OEMs in the aftermarket have intensified the competitive rivalry in the MRO market.
