Underwater Drones Market Size

The global underwater drones market size was valued at USD 7126.14 million in 2025 and is projected to grow from USD 7974.15 million in 2026 to USD 19603.12 million by 2034, registering a CAGR of 11.9% during the forecast period from 2026 to 2034. North America dominated the underwater drones market with a market share of 36.4% in 2025.

Unmanned underwater vehicles (UUVs), commonly referred to as underwater drones, are vehicles that can operate in the ocean and sea without a human occupant. The two main categories of these machines are remotely used underwater vehicles (ROVs), directed by a distant human operator throughout their operations, and autonomous underwater vehicles (AUVs), which can operate independently without any real-time human inputs. Technological advancements in unmanned underwater vehicles, such as high-resolution cameras, superior manipulator arms, and highly sensitive sonar have reduced the time needed to inspect equipment and other submerged items. This has created an ocean of opportunity in the underwater drones market.

Type Insights

The global market is divided into Remotely Operated Vehicles (ROV), Autonomous Underwater Vehicles (AUV), and Hybrid Vehicles. Remotely Operated Vehicle (ROV) is expected to dominate the market, growing at a CAGR of 9.6% during the forecast period. With the continuous technological advancements, state-of-the-art equipment is being incorporated into the ROVs to enhance their capabilities to a more significant extent. The miniaturization of ROVs is another major trend in the market. The rise in demand for oil & gas is expected to influence the direction of ROVs over the years. ROVs have expedited the expansion of oil & gas exploration in deeper water. By allowing access to difficult zones under the oceans, ROVs have enhanced the exploration activities for handling complex operations in deep water.

Autonomous Underwater Vehicles (AUVs) are the fastest-growing segment. AUVs are purchased in significant quantities for security and defense objectives. AUVs are used more frequently by the naval forces of numerous nations, including the US, China, Canada, and France, for operations, including mine countermeasure missions. New AUV models have been introduced in recent years that can carry out their activities for extended periods and collect more data. Such factors drive the segment growth.

Propulsion System Insights

The global market is segmented into Electric Systems, Mechanical Systems, and Hybrid Systems.The Electric System is expected to dominate the market, growing at a CAGR of 12.3% during the forecast period. Advancements in electrical motor technology have increased the number of electrical propulsion ROV & AUV systems. Electric motors are compact and efficient and have a high-power density. They also permit effective operations across a wide range of rotations per minute (RPM), which is favorable for vehicles deployed across several operating surroundings, as with ROVs and AUVs. In recent years, electric motors have become significantly compact due to advancements in electromagnetic designs and permanent magnet materials, among other noteworthy factors. Furthermore, the environmental damage caused by hydraulics, such as leaking fluids and venting, contributes to the increased preference for electric underwater drones worldwide.

The Hybrid System is expected to grow significantly during the forecast period. The rise in exploration of ocean resources is pushing the requirements for long-enduring underwater drones. A reliable approach to decreasing underwater drones' energy consumption is using variable buoyancy systems (VBS) as a substitute or counterpart to thrusters. Full-electric underwater drones are quite effective in shallow depths, as lower forces are required. On the other hand, the electrohydraulic solutions are more efficient for higher-depth surroundings, making them suitable for high-pressure applications. Such factors contribute to segment growth.

Application Insights

The global market is segmented into Defense & Security, Scientific Research, Commercial Exploration, and Others. The Defense & Security application is expected to be the largest segment, growing at a CAGR of 12.2% during the forecast period. Underwater drones are increasingly being adopted by organizations responsible for ocean rescue and port security. ROVs/AUVs are adequate for scanning and observation purposes. Underwater drones benefit many defense and security applications, such as port security, criminal investigations, search & recovery, training, and others. Armed forces are buying underwater drones to improve their operational capabilities.

Commercial Exploration is the second-largest segment. With the technological developments in underwater drones, the capabilities of ROVs and AUVs have grown considerably over the years. Manufacturers such as Oceaneering Inc., ECA group, Saab SeaEye Ltd., and Kongsberg Maritime offer a wide range of oil & gas exploration underwater drones. Pipelines regularly need an inspection, as leaks in the pipelines can lead to terrible catastrophes on offshore structures. The leaks also cause water degradation. Regular maintenance and assessment using underwater drones can prevent leaks and pipeline degradation. Underwater drones capture the images of the pipelines and alert the authorities to perform preventive measures to avoid leakage.

Product Type Insights

The global market is segmented into Micro, Small & Medium, Light Work-Class, and Heavy Work-Class. The Light Work-Class segment is expected to dominate the market, growing at a CAGR of 11.9% during the forecast period. Light work-class underwater drones can be used during inspections to make repairs. Extensions such as laser scanners or dedicated inspection devices and sensors can be added to the underwater vehicle. These drones are used for commercial, defense & security, and scientific applications.

Small & Medium underwater drones are expected to grow significantly during the forecast period. These are mainly used for observation and inspection applications in the research, military, or recreational sectors as they can only endure shallow waters (around 300 meters) and have limited power. Small and medium ROVs/AUVs, for instance, Saab SeaEye’s Falcon, Cougar-XT Compact, and Sea Wasp, are usually deployed for defense operations. Small & medium underwater drones are propelled by electric motors, and hence, the demand for battery-powered small & medium underwater drones is expected to grow considerably over the years.
