Naval vessel maintenance, repair, and overhaul (MRO) operations are critical to ensuring the operational readiness, longevity, and modernization of naval fleets worldwide. As geopolitical tensions persist and navies modernize aging ships, the focus on effective MRO practices is growing rapidly to support national security objectives and technological advancement.
According to Straits Research, the global naval vessel maintenance, repair, and overhaul (MRO) size was valued at USD 56.77 billion in 2024 and is expected to grow from USD 57.85 billion in 2025 to reach USD 67.25 billion by 2033, expanding at a CAGR of 1.90% during the forecast period (2025–2033).

Recent Developments and Technological Innovations
The naval vessel MRO sector is evolving with the integration of advanced technologies aimed at increasing efficiency, reducing downtime, and extending vessel life cycles. Key technological updates include:- Predictive Maintenance and Condition-Based Monitoring: Use of AI, IoT sensors, and data analytics enables real-time tracking of vessel components, helping anticipate failures and optimize maintenance schedules. This reduces unscheduled repairs and enhances operational availability.
- Additive Manufacturing (3D Printing): Warships increasingly benefit from on-demand parts manufacturing, reducing dependency on lengthy supply chains and enabling rapid repair responses.
- Sustainability and Environmental Compliance: With stricter international regulations on emissions and waste, eco-friendly ship recycling processes and green maintenance techniques are being incorporated.
- Digital Twin Technology: Virtual replicas of naval vessels aid in simulation and testing of repair protocols before actual execution, increasing precision and reducing errors.
- Automation and Robotics: Automated dry-docking, hull cleaning robots, and remote inspection drones are improving safety and operational efficiency during repair and overhaul.
