Sonobuoy Market Summary

The global sonobuoy market size was estimated at USD 429.2 million in 2023 and is projected to reach USD 667.0 million by 2030, growing at a CAGR of 6.5% from 2024 to 2030. The market growth is primarily driven by the increasing focus on maritime security as nations around the world enhance their undersea warfare capabilities. With the growing importance of monitoring and securing underwater territories, governments are investing heavily in advanced sonar and surveillance systems, thereby fueling the demand for sonobuoys.

Rising geopolitical tensions in key maritime regions have resulted in higher demand for submarine detection and tracking technologies. The growing deployment of submarines and other underwater defense assets across naval forces globally has intensified the need for efficient anti-submarine warfare (ASW) solutions. Sonobuoys play a critical role in ASW operations by enabling real-time underwater acoustic detection, communication, and tracking, making them an indispensable component in naval defense systems.

In addition, advancements in sensor technology, communication networks, and data analytics have led to the development of next-generation sonobuoys with improved range, accuracy, and reliability. The integration of artificial intelligence (AI) and automation in modern naval operations is further enhancing the performance of sonobuoy systems, allowing for faster decision-making and better situational awareness. The market is also witnessing increased demand for lightweight and cost-effective designs that can be rapidly deployed across multiple maritime zones.
