Diver Detection Sonar Market Report 2026

The diver detection sonar market size has grown rapidly in recent years. It will grow from $0.69 billion in 2025 to $0.76 billion in 2026 at a compound annual growth rate (CAGR) of 10.3%. The growth in the historic period can be attributed to use of underwater acoustic arrays for diver detection, adoption of signal processing units for threat differentiation, installation of sonar sensors in naval operations, growth in maintenance and system integration services, investments in technical support and monitoring services.

The diver detection sonar market size is expected to see rapid growth in the next few years. It will grow to $1.11 billion in 2030 at a compound annual growth rate (CAGR) of 10%. The growth in the forecast period can be attributed to expansion of AI-enhanced sonar signal analysis, integration with autonomous underwater vehicles for surveillance, development of high-precision diver tracking systems, adoption of modular sonar platforms for rapid deployment, growth in real-time remote monitoring and alerting services. Major trends in the forecast period include advancement in underwater signal processing systems, rising deployment of diver detection systems for critical infrastructure, expansion of integrated multi-sonar surveillance networks, increasing use of portable and rapid-deployment sonar systems, growth in long-range acoustic detection capabilities.

The increasing maritime security threats are expected to drive the growth of the diver detection sonar market in the coming years. Maritime security threats refer to unlawful activities such as piracy, terrorism, smuggling, and unauthorized underwater intrusions that pose risks to vessels, ports, naval assets, and coastal infrastructure. These threats have a significant impact on international trade, maritime safety, and the protection of critical naval and offshore facilities. The rise in such threats is fueled by increasing incidents of piracy, terrorism, and geopolitical tensions, along with the expansion of maritime trade and offshore infrastructure, which has increased the need for advanced underwater surveillance technologies. Diver detection sonar strengthens maritime security by detecting, tracking, and classifying underwater threats such as divers and submersibles, enabling quick response to potential intrusions. For instance, in April 2024, according to the ICC International Maritime Bureau (IMB), a Malaysia-based global maritime security organization, 33 incidents of piracy and armed robbery against ships were recorded in the first quarter of 2024, up from 27 incidents during the same period in 2023. Therefore, the growing maritime security threats are fueling the growth of the diver detection sonar market.

Major companies operating in the diver detection sonar market are focusing on developing innovative underwater threat detection systems, such as advanced sonar detection technologies, to achieve accurate, rapid, and autonomous identification of manned and unmanned submersibles. Advanced sonar detection involves the use of highly sensitive acoustic sensors integrated with automated classification algorithms to detect divers, diver propulsion vehicles (DPVs), and autonomous underwater vehicles (AUVs) in real time. For instance, in May 2025, DSIT Solutions Ltd., an Israel-based company specializing in underwater defense and security technologies, launched an advanced version of its PointShield system at IMDEX 2025. This enhanced sonar system provides rapid, reliable, and fully automated detection of underwater intruders, including divers, DPVs, and AUVs. Featuring adaptive software, low false-alarm rates, and flexible deployment across vessels, harbors, and remote sites, PointShield integrates high-precision acoustic sensing with intelligent classification to deliver effective and non-intrusive diver detection.

In May 2025, Elbit Systems Ltd., an Israel-based defense technology company, collaborated with NATO to strengthen naval defense capabilities. Through this partnership, Elbit will supply advanced maritime technologies, including the Seagull unmanned surface vessel (USV), towed reelable active passive sonar (TRAPS), combat management systems, electronic warfare technologies, and electro-optic systems, along with modernization upgrades for offshore patrol vessels and frigates. The North Atlantic Treaty Organization (NATO) is a Belgium-based intergovernmental military alliance established to ensure collective defense among its member nations.

North America was the largest region in the diver detection sonar market in 2025. Asia-Pacific is expected to be the fastest-growing region in the forecast period. The regions covered in the diver detection sonar market report are Asia-Pacific, South East Asia, Western Europe, Eastern Europe, North America, South America, Middle East, Africa.

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 on acoustic electronics, underwater sensors, communication modules, and power systems have raised production and procurement costs across diver detection sonar systems, especially affecting hardware-intensive segments like hull-mounted and fixed sonar installations. Regions dependent on imported marine electronics, including Europe and Asia-Pacific, face delays and higher deployment expenditures. However, tariffs are also encouraging domestic manufacturing of sonar components, strengthening regional supply chains, and supporting innovation in locally engineered underwater surveillance technologies.

This diver detection sonar market research report delivers a complete perspective of everything you need, with an in-depth analysis of the current and future scenarios of the industry.

Diver detection sonar is an advanced underwater system developed to identify and monitor submerged human activity. It operates by emitting sound waves to detect the presence, movement, and location of divers in aquatic environments. The system offers real-time monitoring capabilities and can distinguish between marine life, underwater vehicles, and humans.

The primary types of diver detection sonar include hull-mounted sonar, portable diver detection sonar, fixed diver detection sonar, and others. Hull-mounted sonar refers to sonar systems that are installed directly on the hulls of vessels to detect, track, and classify underwater threats such as divers and submersibles. These systems utilize active sonar, passive sonar, or dual-mode technologies to improve underwater surveillance and security. The key applications include commercial, defense and military, critical infrastructure, ports and harbors, offshore platforms, and others, with primary end users including military and naval, oil and gas, ports and harbors, civilian, and others.
