Towed Array Sonar System Market Report 2026

The towed array sonar system market size has grown strongly in recent years. It will grow from $2.02 billion in 2025 to $2.18 billion in 2026 at a compound annual growth rate (CAGR) of 7.7%. The growth in the historic period can be attributed to increasing naval modernization programs, growing anti-submarine warfare activities, rising deployment of surface and subsurface fleets, expanding maritime security threats, and increasing investments in underwater surveillance systems.

The towed array sonar system market size is expected to see strong growth in the next few years. It will grow to $2.91 billion in 2030 at a compound annual growth rate (CAGR) of 7.5%. The growth in the forecast period can be attributed to growing demand for advanced ASW capabilities, rising adoption of unmanned naval platforms, expanding maritime border protection initiatives, increasing procurement of next-generation sonar systems, and growing focus on deep-sea monitoring operations. Major trends in the forecast period include advancements in thin-line and variable-depth array technologies, innovations in digital signal processing, developments in low-frequency passive detection systems, research and development in AI-enabled acoustic analysis, and technological advancements in lightweight towed array materials.

The growing investment in maritime security is expected to drive the growth of the towed array sonar system market in the coming years. Maritime security encompasses initiatives by governments and defense organizations to protect territorial waters, ports, and shipping routes from threats such as piracy, smuggling, and naval conflicts. The increase in investment is driven by rising concerns over piracy and other maritime threats. Towed array sonar systems support maritime security by delivering advanced sonar capabilities that detect submarines, underwater threats, and surface vessels with high accuracy and over extended ranges. For example, in March 2023, according to the U.S. Department of Transportation, a US-based government agency, the U.S. Maritime Security Program (MSP) - a key national security initiative supporting DoD sealift capability and maritime logistics - was funded at $318 million annually for FY 2022, FY 2023, and FY 2024. Therefore, the rising investment in maritime security is contributing to the expansion of the towed array sonar system market.

Leading companies operating in the towed array sonar system market are focusing on the development of advanced systems, such as autonomous sonar-integrated uncrewed systems, to enhance persistent maritime domain awareness, improve threat detection, and reduce operational costs. Autonomous sonar-integrated uncrewed systems combine high-performance towed-array sonar, advanced signal processing, and long-endurance autonomous vehicles powered by wind and solar, enabling continuous surface, subsurface, and unmanned underwater vehicle (UUV) monitoring in remote or high-traffic waters. For instance, in April 2025, Thales Australia Ltd, an Australia-based defense technology company, and Saildrone, Inc., a US-based autonomous maritime systems provider, successfully integrated BlueSentry sonar with Saildrone’s Surveyor-class uncrewed systems during a 26-day trial off California. The combined system detected and tracked surface vessels, submarines, and UUVs in real time, demonstrating scalable, persistent surveillance capabilities for AUKUS-aligned undersea warfare and maritime security operations. By combining autonomous mobility with advanced sonar sensing, the system provides a cost-effective, self-sustaining alternative to traditional manned maritime surveillance platforms.

In April 2024, Saildrone Inc., a US-based developer of uncrewed surface vehicles (USVs), partnered with Thales Australia Holdings Pty Ltd to strengthen persistent maritime surveillance and intelligence capabilities for defense and border security operations. Through this collaboration, Saildrone aims to enhance autonomous anti-submarine warfare (ASW) capabilities by enabling long-endurance, open-ocean intelligence, surveillance, and reconnaissance (ISR) missions, allowing traditional manned naval assets to focus on other critical operations. Thales Australia Holdings Pty Ltd is an Australia-based provider of advanced underwater sensor and towed array technologies supporting naval defense applications.

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 have affected the towed array sonar system market by increasing costs of imported hydrophones, fiber optic cables, and precision signal processing components. these impacts are most evident in active and hybrid towed array segments and in regions such as asia-pacific and europe that depend on global defense supply chains. higher system costs may delay some naval procurement programs, while tariffs are also encouraging domestic manufacturing, supply chain localization, and long-term investment in indigenous sonar technologies.

A towed array sonar system is a long, flexible line of hydrophones deployed behind a vessel to detect underwater sounds with high sensitivity. It improves the capability to identify, track, and classify submarines, marine life, and other underwater objects over extended distances. The system offers superior directional accuracy by distancing the sensors from the vessel’s own noise and turbulence.

The primary product types of towed array sonar systems include active towed arrays, passive towed arrays, multi-functional towed arrays, and hybrid towed arrays. Active towed arrays transmit acoustic signals and receive returning echoes to detect and track underwater targets. The frequency ranges include low, medium, and high frequencies. The platforms include surface vessels, submarines, unmanned underwater vehicles, and aircraft. The applications include anti-submarine warfare, surveillance, oceanographic research, and naval intelligence, with end users including government and military, commercial enterprises, and research institutions.
