Global Leading Market Research Publisher QYResearch announces the release of its latest report “Submarine, Submersible, AUV, ROV, etc Sonar – Global Market Share and Ranking, Overall Sales and Demand Forecast 2026-2032″. This comprehensive study addresses a critical defense and commercial imperative: achieving superior underwater situational awareness in an era of contested maritime domains, expanding offshore energy infrastructure, and proliferating uncrewed systems. For naval forces, offshore energy operators, and subsea infrastructure owners, the core challenge lies in detecting, classifying, and tracking underwater objects across diverse operating environments—from deep-ocean basins to complex littoral waters—while adapting to the rapid proliferation of uncrewed underwater vehicles (UUVs). Underwater sonar systems provide the essential solution, leveraging active and passive acoustic technologies to deliver high-resolution imaging, wide-area surveillance, and precise target detection across military and civilian applications. By analyzing historical market dynamics from 2021-2025 and forecasting through 2032, this report delivers actionable intelligence on market size, share, industry development status, and the technological shifts reshaping undersea warfare and subsea inspection strategies.
The global market for Submarine, Submersible, AUV, ROV, etc Sonar was estimated to be worth US$ 2,202 million in 2025 and is projected to reach US$ 3,228 million, growing at a CAGR of 5.7% from 2026 to 2032. The sonar market for submarines, submersibles, AUVs, and ROVs is entering a phase of steady expansion combined with clear structural upgrades. Industry revenues increased from approximately USD 1.5 billion in 2020 to around USD 2.0 billion in 2024, with 2025 expected at roughly USD 2.2 billion on sales of about 1,833 units. Over 2025–2031, total revenue is projected to grow at a compound rate of around 5.7% and unit volume at about 5.1%. By configuration, active sonar systems account for roughly 35% of revenues in 2025 but are on track to approach 40% by 2031, with an estimated revenue CAGR close to 8%, significantly outpacing passive and combined systems. In application terms, military programs still represent about 71% of 2025 revenues, yet civilian segments—offshore wind, oil and gas, subsea infrastructure inspection, and ocean science—are expected to grow faster, with a revenue CAGR of roughly 7% versus just above 5% on the military side.

Competitive Landscape & Market Structure
The competitive landscape is shaped by large defense primes on one side and highly specialized underwater-acoustics players on the other. Lockheed Martin, Thales, L3Harris Technologies, General Dynamics, and Northrop Grumman together generate around USD 1.0 billion of sonar-related revenues in 2025, representing approximately 46% of the market. Lockheed Martin remains a key integrator with the AN/SQQ-89 family of undersea warfare combat systems, which fuses hull-mounted, towed-array, and sonobuoy sensors into a single ASW picture for AEGIS-equipped surface combatants. Thales combines submarine sonar suites, the CAPTAS variable-depth towed sonar family, and mine countermeasure systems, and is widely recognized as a leading global exporter of naval sonar solutions, with dozens of CAPTAS systems contracted by major navies.
Below the primes, a dynamic group of specialist companies is capturing growth in high-resolution imaging and seabed mapping. Kongsberg builds on its HUGIN AUV family and HISAS synthetic aperture sonar to deliver wide-area, high-resolution seabed coverage for defense and commercial customers. Kraken Robotics focuses on synthetic aperture sonar payloads and services, offering centimeter-class resolution and high area coverage for offshore energy, mine countermeasures, and seabed warfare experiments. NORBIT, Teledyne Technologies, General Oceans, Coda Octopus, and others provide compact multibeam and imaging sonars optimized for small AUV/ROV and survey platforms, emphasizing low power consumption and broadband performance for harbor security, pipeline inspection, and research missions. On the programs side, the U.S. Navy’s 2024 contract modification of approximately USD 180 million to Lockheed Martin for continued AN/SQQ-89A(V)15 engineering and system deliveries illustrates how navies are using multi-year awards to sustain undersea warfare capabilities while funding open-architecture upgrades.
Industry Segmentation & Application Dynamics
Understanding industry segmentation is essential for stakeholders navigating this complex market. The market is categorized by sonar type into Active Type, Passive Type, and Combined Type. Active sonar systems—which emit acoustic pulses and analyze returning echoes—are gaining share in high-end naval programs due to their superior detection capabilities in complex littoral environments and contested seabeds. Passive sonar systems, which listen for acoustic signatures without emitting detectable signals, remain critical for stealth operations and submarine detection.
By application, military programs dominate current revenues, but the civilian segment is accelerating. The offshore wind sector, in particular, is driving demand for high-resolution seabed mapping and cable inspection sonars, with developers requiring detailed geophysical surveys for site characterization and post-installation asset monitoring. Similarly, the oil and gas industry continues to rely on advanced sonar systems for pipeline inspection, riser monitoring, and subsea infrastructure integrity assessments.
Exclusive Insights & Future Trajectory
Over the past six months, several structural themes have defined the sonar landscape. First, active and multistatic concepts—variable-depth towed arrays, synthetic aperture sonar, and multi-frequency combinations—continue to gain share in high-end naval programs, driven by the need to operate in complex littoral environments and contested seabeds. Second, the rapid proliferation of uncrewed underwater and surface vehicles will sustain double-digit unit growth for compact, low-power, high-bandwidth sonar payloads that can be flexibly deployed for mine countermeasures, seabed warfare, and offshore asset inspection. Third, signal processing, automatic classification, and mission management are becoming increasingly software-defined, with algorithms migrating onto open architectures and commercial compute platforms.
A compelling user case illustrates these trends. A European offshore wind developer recently deployed a fleet of AUVs equipped with synthetic aperture sonar and multibeam echosounders for high-resolution cable route surveys across a 500-square-kilometer development area. The system achieved 5-centimeter resolution seabed imagery, reducing survey time by 40% compared to traditional towed systems and enabling precise cable burial depth verification, demonstrating the efficiency gains achievable through integrated AUV-sonar solutions.
From an original research perspective, the convergence of artificial intelligence with underwater acoustics represents the next frontier. Traditional sonar systems rely heavily on operator interpretation for target classification. Emerging systems leverage machine learning algorithms trained on vast acoustic datasets to automatically detect, classify, and track underwater objects—from submarines and mines to marine mammals and seabed features. Vendors that combine acoustic hardware expertise with strong software and integration capabilities, and that straddle both military and civilian use cases, will be best positioned to capture the structural growth in this evolving sonar ecosystem. Additionally, the development of low-power, miniaturized sonar systems compatible with small UUV platforms is opening new applications in harbor security, environmental monitoring, and rapid environmental assessment, expanding the total addressable market beyond traditional naval programs.
