Global Military Maintenance, Repair & Overhaul (MRO) Market to Surpass USD 120 Billion by 2035

The Global Military Maintenance, Repair & Overhaul (MRO) Market is gaining strategic significance as nations worldwide focus on maintaining combat readiness, extending the operational lifespan of defense assets, and ensuring peak mission performance. Valued at USD 84.6 billion in 2024, the market is projected to grow from USD 87.3 billion in 2025 to USD 120 billion by 2035, registering a steady CAGR of 3.2% during the forecast period. This sector encompasses critical maintenance, inspection, component overhaul, and system upgrades across air, land, and naval defense platforms. As global militaries modernize their fleets and pursue more sustainable operations, MRO has evolved from a support function into a strategic pillar of defense capability.

The growing complexity of defense platforms—ranging from next-generation aircraft and armored vehicles to advanced naval systems—has increased the need for sophisticated maintenance and lifecycle management. Governments and defense contractors are now prioritizing predictive maintenance, digital twins, and AI-driven diagnostics to ensure mission readiness and cost efficiency. In an environment of rising geopolitical tensions and aging military infrastructure, MRO investments have become critical for sustaining operational superiority without excessive capital expenditure on new equipment.

Growth Drivers

A key driver behind the expansion of the military MRO market is the global defense modernization trend. Rather than replacing entire fleets, many defense forces are extending the service life of existing systems through advanced repair, refurbishment, and upgrade programs. This approach not only reduces procurement costs but also ensures continuity in logistics and training. Another major growth factor is the adoption of advanced maintenance technologies, such as augmented reality (AR) for technician training, AI for fault detection, and data analytics for condition-based maintenance. These technologies enhance efficiency, reduce downtime, and improve resource allocation.

Additionally, rising defense budgets in countries like the U.S., China, India, and members of NATO are strengthening the market outlook. Modern warfare requires adaptable systems, and maintenance strategies are evolving accordingly to accommodate modular components, software upgrades, and hybrid propulsion systems. The expansion of international peacekeeping operations and joint defense exercises further amplifies the need for standardized and interoperable MRO frameworks.

Emerging Trends

The military MRO industry is undergoing a digital transformation. The integration of smart maintenance ecosystems—leveraging IoT sensors, blockchain-based maintenance records, and digital twins—is revolutionizing how militaries track and manage their assets. Predictive maintenance is replacing traditional scheduled servicing, reducing costs and preventing critical system failures.

Another emerging trend is the outsourcing of MRO services to private defense contractors. As governments seek to improve efficiency, contract-based maintenance partnerships are becoming more common, especially in air and naval segments. This allows militaries to focus on core operations while leveraging specialized industrial expertise. Sustainability is also taking center stage, with a growing emphasis on eco-friendly repair processes, energy-efficient depots, and recyclable materials—reflecting a global push toward greener defense operations.

In addition, the regional diversification of MRO capabilities is gaining momentum. Nations are investing in local MRO infrastructure to reduce dependence on foreign service providers and enhance supply chain resilience. Emerging economies in Asia-Pacific and the Middle East are particularly active in developing indigenous maintenance hubs supported by technology transfer agreements with leading OEMs.

Market Opportunities

The future of the military MRO market is filled with opportunities for innovation and strategic partnerships. The growing use of unmanned aerial systems (UAS), cyber-defense tools, and space-based assets will open new domains for specialized maintenance services. Companies offering modular and digital MRO solutions will be best positioned to capture this emerging demand.

Furthermore, data-driven maintenance will become a differentiating factor for defense forces aiming to optimize operational readiness with minimal downtime. The increasing convergence between defense MRO and commercial aviation maintenance also presents cross-sector opportunities for companies with multi-domain expertise. As defense organizations continue to face pressure to enhance efficiency while managing costs, the integration of AI, robotics, and automated supply chain systems will define the next generation of military MRO excellence.

Future Outlook

Looking ahead, the Military Maintenance, Repair & Overhaul Market is expected to remain a cornerstone of global defense readiness. By 2035, with projected revenues of USD 120 billion, the market will reflect a broader transformation—one defined by predictive intelligence, automation, and sustainability.

Governments are likely to invest heavily in smart depots, autonomous maintenance systems, and collaborative frameworks that connect military logistics with digital command systems. Meanwhile, the private sector’s role will continue to expand, with defense contractors and OEMs forming long-term partnerships to provide integrated maintenance solutions that span the entire lifecycle of defense assets.

As the boundaries of defense technology expand—from cyberspace to outer space—the importance of effective, efficient, and adaptive maintenance systems will only grow. In this context, the MRO industry is not just sustaining equipment—it is sustaining national security, operational reliability, and the future of global defense.
