The growth in the forecast period can be attributed to advancements in autonomous and unmanned maritime systems enhancing surveillance coverage and responsiveness, rising investment in integrated maritime domain awareness platforms improving data fusion and decision-making, expanding coastal infrastructure and trade routes increasing need for advanced intervention services, growing adoption of satellite-based monitoring systems strengthening long-range maritime surveillance, increasing emphasis on climate and environmental risk management driving demand for advanced monitoring and intervention technologies. Major trends in the forecast period include expansion of integrated maritime domain awareness platforms, rising adoption of multi-sensor surveillance systems, growth in coastal border security modernization programs, increased demand for real-time vessel traffic intelligence, advancements in environmental and atmospheric marine monitoring.

Increasing military spending is anticipated to drive the growth of the maritime surveillance and intervention market in the coming years. Military spending refers to the allocation of financial resources by a government or nation to support its armed forces, defense infrastructure, and associated operations. Higher military expenditure leverages maritime surveillance and intervention to protect national interests and secure strategic sea routes amid geopolitical tensions and security challenges. For example, in April 2024, the Stockholm International Peace Research Institute, a Sweden-based international organization, reported that global military spending reached approximately $2.29 trillion in 2022, rising to $2.44 trillion in 2023, marking a 6.8% year-over-year increase. Consequently, the growth in military spending is fueling the expansion of the maritime surveillance and intervention market.

Key industry players are concentrating on the development of sophisticated technologies, such as underwater surveillance, to improve detection capabilities, real-time monitoring, and the protection of vital maritime assets. For example, in May 2023, Image Soft Oy, a defense and space manufacturing company based in Finland, introduced the 3rd Generation Underwater Surveillance System (UNWAS), representing a major leap forward in underwater monitoring. This cutting-edge system aims to protect essential underwater infrastructure, including pipelines, subsea cables, and harbors, by providing continuous automated oversight. Functioning around the clock, the highly automated UNWAS system is not only cost-efficient but also environmentally friendly, effectively operating in various environments, from the Baltic and North Seas to tropical waters. Featuring a passive sensor network, UNWAS can identify a broad spectrum of underwater and surface threats, such as submarines, divers, autonomous underwater vehicles (AUVs), remotely operated vehicles (ROVs), and underwater drones. With a detection range of over 30 kilometers under ideal conditions, this system signifies a substantial enhancement in naval capabilities and maritime security. As countries continue to invest in innovative surveillance technologies, systems like UNWAS will be essential for future maritime security initiatives.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

Tariffs are influencing the maritime surveillance and intervention market by increasing the cost of importing critical technologies such as radar systems, EO/IR sensors, GIS platforms, and surveillance hardware, ultimately slowing system upgrades and procurement cycles. The most affected areas include surveillance and tracking systems, detectors, and combat management components, particularly across regions dependent on foreign defense electronics. Naval and coast guard applications feel the pressures most acutely due to their reliance on integrated high-value systems. However, tariffs are also encouraging domestic manufacturing, local technology development, and regional supply-chain strengthening, creating new opportunities within emerging defense industrial bases.
