Polaris Market Research today announced findings from its latest report, projecting the global Sonar Systems Market to grow from USD 4.85 billion in 2025 to USD 9.35 billion by 2034, at a CAGR of 7.58% from 2026 to 2034. The 289-page report profiles 15 leading companies across seven segmentation axes: product, technology, platform, component, installation type, application and end user.

Analyst Commentary on Sonar Systems Market Growth

“Rising defense expenditure and naval modernization are putting underwater surveillance at the top of procurement agendas, and demand for anti-submarine warfare capability is the clearest signal in current industry trends,” said an analyst at Polaris Market Research. “For buyers and investors, the opportunity sits in retrofit programs, software upgrades and compact sonar for unmanned vehicles, where suppliers can add capability without replacing entire platforms.”

Key Growth Drivers, Major Companies and Segments Covered

Growth Drivers: Rising defense expenditure and naval fleet modernization, expanding ocean mapping and environmental monitoring, and new subsea inspection work are the primary forces behind the market's expansion, alongside growing demand for AI-assisted signal processing. In August 2026, India's DRDO highlighted indigenous sonar systems aboard recently commissioned naval ships, while NOAA's June 2026 Pacific Islands expedition used multibeam sonar for deepwater mapping. High system costs and complex integration with older vessels remain the main restraint.

Major Companies Covered:

• ASELSAN A.Ş.,
• BAE Systems,
• Elbit Systems,
• FURUNO ELECTRIC,
• General Dynamics,
• Kongsberg Gruppen,
• L3Harris Technologies,
• Leonardo,
• Lockheed Martin,
• Northrop Grumman,
• RTX,
• Saab,
• Teledyne Technologies,
• Thales Group
• TKMS ATLAS ELEKTRONIK.

Segments Covered: By Product (Hull-Mounted, Stern-Mounted, Sonobuoy, Diver Detection Sonar), By Technology (Active, Passive, Dual-Mode), By Platform (Ship, Submarine, Airborne, UUV, Seabed), By Component, By Installation Type, By Application, By End User, By Region.

Segment Snapshot: Hull-Mounted, Passive and Retrofit Lead

Hull-mounted sonar led by product with a 44.50% share in 2025, while passive sonar held 49.00% by technology and ships accounted for 46.0% by platform. Transducers captured 34.60% of component revenue, retrofit installations represented 54.00% of the installation mix, and defense applications generated 68.00% of demand, with naval forces the largest end user at 46.00%. Growth is tilting toward newer formats: dual-mode sonar is projected to expand at a 10.08% CAGR, software at 10.12%, sonobuoys at 8.28%, line-fit installations at 8.35% and commercial applications at 8.35%. Airborne platforms are also expected to be among the fastest-growing, as maritime patrol aircraft and sonobuoy networks extend underwater coverage.

Technology Trends Shaping Procurement

Beyond defense, subsea infrastructure inspection of pipelines, cables and port structures, along with sonar mounted on remotely operated and autonomous vehicles, is opening new commercial demand. Modular architectures allow upgrades without replacing the whole system, multi-frequency designs balance long-range detection against fine detail, and AI-based classification reduces operator workload. Active sonar measures range through echoes but can reveal the platform's position, while passive sonar listens covertly, which explains why dual-mode designs are gaining traction.

Recent Developments

• August 2026: ELAC SONAR, a Cohort subsidiary, secured a €140.7 million contract from Saab for integrated active and passive sonar systems for Poland's Orka submarine program, with deliveries planned through the mid-2030s.
• July 2026: Lockheed Martin announced an agreement to acquire Ultra Maritime for USD 3.45 billion, adding sonobuoys, towed sonar arrays and hull-mounted sonar to its portfolio, subject to closing conditions.

Regional Snapshot: North America Leads, Asia Pacific Fastest-Growing

North America led with a 33.0% share in 2025, supported by sustained naval investment and a deep base of sonar suppliers. Europe followed with 25.5%, driven by fleet modernization and replacement cycles for aging equipment. Asia Pacific is projected to register the fastest CAGR at 8.99% through 2034 on the back of rising maritime security challenges and naval build-ups. Middle East & Africa (8.22% CAGR) and Latin America (7.32% CAGR) are expanding on offshore energy, port development, fisheries and seabed survey demand, with unmanned underwater systems adding demand for compact sonar across all five regions.

Why It Matters for Stakeholders Tracking the Market Forecast 2034

For stakeholders researching the top sonar companies and the market forecast to 2034, the underlying report benchmarks market share, company positioning, and segment-level forecasts to support sourcing, partnership, and investment decisions through 2034.

Conclusion

Underwater surveillance is moving from a narrow defense purchase to a broader technology category. Naval modernization, retrofit demand, AI-assisted processing and compact, modular sonar for unmanned platforms are widening the customer base beyond navies, even as cost and integration hurdles keep competition focused on delivery capability. With the market on course to nearly double by 2034, suppliers that pair dependable hardware with software-led upgrades are best placed to capture the next wave of procurement.
