India Defense Maintenance, Repair, and Overhaul Market Size and Outlook

The defense maintenance, repair, and overhaul market in India was estimated at USD 3.40 billion in 2025 and is projected to reach USD 3.65 billion in 2026 and USD 5.75 billion by 2032, registering a CAGR of approximately 7.87% during 2026–2032.

Sustained market growth is supported by the country's large and increasingly sophisticated defense asset base, continued fleet modernization, rising domestic defense production, and the need to maintain high operational availability of military platforms. MRO demand is further supported by the ongoing lifecycle requirements of assets already in service, creating a recurring expenditure base that is likely to expand as India simultaneously operates legacy platforms and inducts newer, technologically complex systems.

India's defense spending provides a substantial underlying financial base for this ecosystem. The Ministry of Defense received a record allocation of ~USD 70.50 billion for FY2025–26, representing a 9.53% increase over the FY2024–25 Budget Estimate and equivalent to 13.45% of the Union Budget. Of this, approx. USD 18.65 billion was allocated to capital outlay for defense services, while USD 32.54 billion was allocated to the Armed Forces under the revenue head. The latter is particularly relevant as an indicator of the recurring expenditure environment surrounding the operation and sustainment of the country's defense assets, although the revenue allocation is not equivalent to MRO expenditure.

The capital allocation is also important to the longer-term MRO outlook because every new platform inducted into service creates a future stream of maintenance, repair, overhaul, inspection, component support, and modernization requirements. As the asset base matures, the associated demand for maintenance, repair, overhaul, upgrades, inspections, and technical support is expected to increasingly become a significant and recurring component of the country's defense industrial economy.

India Defense Maintenance, Repair, and Overhaul Market Growth Drivers

New Platform Inductions and Existing Fleet Requirements

Continued induction of new defense platforms is expanding the future installed base requiring recurring maintenance and lifecycle support. For instance, the Ministry of Defense signed a USD 6.54 billion contract for 156 LCH Prachand helicopters in March 2025, comprising 66 helicopters for the Indian Air Force and 90 for the Indian Army . Similarly, the USD 6.51 billion contract for 97 LCA Tejas Mk1A aircraft, signed in September 2025, is expected to add a substantial number of indigenous fighter aircraft to the operational fleet from 2027–28 onward. These acquisitions create long-term demand for scheduled maintenance, repairs, component support, inspections, upgrades, and overhauls throughout the platforms' operational lifecycles.

India's simultaneous operation of legacy platforms is further increasing the complexity and intensity of lifecycle support requirements. Older assets typically require more frequent repairs, component replacement, and refurbishment. This environment is likely to support demand for efficient repair turnaround, depot-level maintenance, component MRO, and modernization services.

Recent Trends

Increasing Adoption of Predictive Maintenance and Digital MRO Technologies

The India Defense MRO industry is witnessing a gradual shift from conventional time-based maintenance toward predictive, condition-based, and digitally enabled maintenance practices, driven by the increasing technological sophistication of military platforms and the need to improve operational readiness. Modern defense assets incorporate advanced architectures that require continuous health monitoring, diagnostics, and data-driven maintenance rather than reactive repairs alone. Consequently, MRO providers are increasingly integrating digital diagnostics, AI-enabled fault detection, digital twins, condition monitoring, and advanced inspection technologies to reduce unplanned downtime and optimize maintenance cycles.

This transition is reflected in the development of digitally integrated defense MRO infrastructure in India. In March 2026, Tata Advanced Systems Limited selected Ramco Systems’ aviation software to provide the digital backbone for its upcoming MRO facility supporting the Indian Air Force’s C-130J Super Hercules fleet. The platform will integrate maintenance planning, hangar and component maintenance, engineering, quality management, and supply-chain operations, demonstrating how digital systems are being embedded across the maintenance workflow.

The signing of three agreements by IAF and IIT Bombay in May 2026 to develop AI-driven predictive maintenance for the Su-30MKI fleet further highlights the objective of reducing maintenance costs, increasing aircraft availability, and extending service life through digital technology adoption.

India Defense Maintenance, Repair, and Overhaul Market Opportunities and Challenges

Continued Dependence on Foreign OEMs Creates Lifecycle Support Challenges while Driving Ecosystem Localization

India's defense MRO market continues to face structural challenges arising from its dependence on foreign OEMs for the maintenance of several advanced aircraft, aero engines, avionics, electronic warfare systems, and mission-critical components. For many imported platforms, major overhauls, proprietary software updates, specialized repairs, and critical spare parts remain subject to OEM approvals, intellectual property restrictions, and global supply chains, which can increase maintenance costs, extend turnaround times, and affect fleet availability.

At the same time, these constraints are accelerating efforts to localize high-value maintenance capabilities within India. A notable example is the Ministry of Defence's ~USD 48 million contract awarded in March 2026 for depot-level inspection of the Indian Navy's P-8I maritime patrol aircraft, which will be executed at an in-country MRO facility with 100% indigenous content. Similarly, the Defence Acquisition Council's Acceptance of Necessity (AoN) for capital acquisitions worth approximately USD 43 billion in February 2026 is expected to expand the future installed base of sophisticated defense platforms requiring long-term domestic lifecycle support.
