Bangalore. 06 February 2025. As the aerospace industry moves towards futuristic aspirations, the need for manufacturing innovation and maintenance that aligns with evolving industry standards becomes increasingly critical. The sector has experienced substantial growth in recent years, with the Aerospace and Defense Global Market Report 2025 projecting an increase in market size from USD 820.67 billion in 2024 to USD 875.37 billion in 2025, reflecting a compounded annual growth rate (CAGR) of 6.7%.

This rapid expansion underscores the pivotal role of Maintenance, Repair, and Overhaul (MRO) in ensuring the safety and efficiency of aerospace operations. MRO manufacturing encompasses various aspects, including equipment production, maintenance, material handling, production repair, and tooling.

The Importance of MRO

India’s MRO industry, though currently in its nascent stage with a market size of USD 1.7 billion in 2021, is projected to reach USD 4.0 billion by 2031, according to the NITI Aayog Report. As aerospace commercialization intensifies, the demand for effective supply chains, skilled personnel, advanced tools, and reliable equipment becomes paramount. Thus, the role of MRO in the aerospace sector cannot be overstated.

Key Drivers of MRO Growth

Several factors are driving the expansion of the MRO industry, including:
