Sonobuoy Market is estimated to be valued at USD 499.7 Mn in 2025 and is expected to reach USD 755.8 Mn in 2032, exhibiting a compound annual growth rate (CAGR) of 6.1% from 2025 to 2032.
Modernization programs in global naval forces are significantly contributing to the growth of the sonobuoy market. This growth is further fueled by rising marine threats, increased submarine activity, and the growing need for enhanced maritime surveillance. The increasing emphasis on securing regional waters and Exclusive Economic Zones (EEZs) has prompted defense agencies to adopt advanced sonar technologies such as sonobuoys for anti-submarine warfare (ASW) and marine research. Modern integrated smart sonobuoy systems, which offer real-time data transmission and advanced signal processing, are improving situational awareness and operational efficiency. Technological advancements like GPS-enabled deployment, multi-beam sonar systems, and AI-driven data analytics platforms are enhancing both the commercial appeal and strategic utility of sonobuoys. In 2024, the U.S. Navy awarded a major contract to ERAPSCO (a joint venture between Sparton Corp and Ultra Electronics) for the supply of advanced SSQ-125 sonobuoys. These sonobuoys are equipped with GPS synchronization and improved acoustic detection features, designed to enhance underwater threat detection capabilities, showcasing how innovation and defense modernization are driving market growth.

The growing placement of Sonobuoy to detect submarine increases the development of the global Sonobuoy market significantly. A Sonobuoy is an acoustic sensing device designed to catch under water sound signals, usually distributed by marine aircraft or ship. These systems use hydophones to detect and monitor acoustic emissions from submarines, transfer data through radio signals for analysis or radio signal for aircraft. Sonobuoy is often released to accurately triangle the location of underwater hazards in a coordinated pattern. It is important to detect an initial submarine to prevent potential attacks and reduce loss of resource, making Sonobuoy necessary in modern marine defence strategies.
In 2020, for example, Ultra Electronics-On Defence, Safety and Aerospace Company schemes announced schemes through its student signal system departments, such as developing the next generation of Sonobuoy to develop an extended range of directional frequency analysis and recording (ER-Dealer).
The global Sonobuoy market is seen to have strong growth, fuel from the growing demand for advanced anti -marine war (ASW) technologies in major modern marine operations. Since marine security becomes a growing concern for nations around the world, there is a need to detect and neutralize underwater hazards - especially submarines have become a top priority. This has led to a significant increase in the adoption of the Sonobuoy system of marine forces worldwide.
In June 2024, China's coast guard retrieved a sonobuoy dropped by a U.S. Navy P-8 Poseidon aircraft in the South China Sea. The device, identified as a submarine detection sensor manufactured by Ultra Electronics Undersea Sensor Systems, Inc., underscores the strategic importance of sonobuoys in maritime surveillance and the sensitive nature of such technologies in contested regions.
One of the most important challenges Sonobuy Market faces is the limited limit for underwater communication. Sonobuoy rely on signs to transfer data to obtain stations and other water platforms. However, the underwater environment presents significant obstacles to sound transmission, as acoustic waves are exposed to rapidly decay and can be affected by variables such as water temperature, salinity and surrounding noise. These environmental factors distribute the effective communication limit between Sonobuoy and control units, potentially prevents real -time data transfer and delay significant response tasks during naval operations.
A significant challenge in the sonobuoy market is the limited communication capability in the underwater environment. Sonobuoys rely on acoustic signals to transmit information to receiving stations and underwater platforms. However, the effectiveness of these signals is often compromised due to the complex nature of underwater sound propagation. Factors such as water temperature, salinity, pressure variations, and background noise can lead to signal attenuation and distortion. These challenges directly impact the detection range for the sonobuoy market, as reduced communication capabilities can hinder the timely transmission of critical data and affect the reliability and accuracy of maritime operations.
Strategic Collaborations Driving Innovation in Undersea Surveillance Technologies
The evolving landscape of maritime security has intensified the global need for sophisticated underwater detection systems. Among these, sonobuoys have emerged as essential tools for naval forces seeking to strengthen their anti-submarine warfare (ASW) capabilities. Their role in tracking underwater threats has made them increasingly valuable as countries modernize their naval assets and seek technological superiority in undersea warfare.
In January 2025, Ultra Maritime, a U.S.-based leader in undersea warfare technologies, announced a strategic partnership with India's Bharat Dynamics Limited (BDL) to co-produce sonobuoys for the Indian Navy. This collaboration aligns with the U.S.-India Initiative on Critical and Emerging Technologies and aims to enhance undersea domain awareness through the joint production of U.S.-specification sonobuoys.
Following the application segment, the detection segments are estimated to dominate the global Sonobuoy market in 2025, which is approximately 56.4% of the total market share in terms of value. The position of this strong market is attributed to the increasing demand for high-demonstration Sonobuoy that can explore and track the goals for effective submarines, unmanned water vehicles and navigation vessels such as water.
Detection sonobuoys are equipped with advanced acoustic sensors and communication systems, enabling real-time monitoring and high-speed data transmission. Their critical role in enhancing naval situational awareness and supporting anti-submarine warfare (ASW) operations has made them a preferred choice for defence forces worldwide. As underwater threats and maritime security challenges continue to rise, the strategic deployment of sonobuoys in coastal defense, mission monitoring, and maritime patrol operations is expanding. This growing demand is significantly contributing to the overall growth of the sonobuoy market size, as nations invest heavily in modernizing their underwater surveillance capabilities.
In the context of final use division, naval strength continues to dominate the sonobuoy market, driven by an increasing focus on strengthening anti-submarine warning systems and enhancing maritime domain awareness. With rising submarine activity and escalating regional tensions—particularly in areas such as Asia-Pacific and the Middle East—naval agencies are making significant investments in underwater monitoring and detection technologies. Advanced sonobuoy manufacturing technologies are playing a crucial role in this evolution, enabling the production of more flexible, rapidly deployable, and highly efficient sonobuoys. These innovations enhance the ability to detect threats in both deep and shallow waters, reinforcing the importance of sonobuoys within the broader underwater defence ecosystem.
Research and investigative sections also gain momentum, the benefit of Sonobuoy with environmental monitoring agencies and scientific institutions for marine engineering research and maritime protection. As the demand for multifunctional, high accurate acoustic systems increases, manufacturers are focused on developing innovative solutions for both defence and scientific applications.
