The global sonar systems market is projected to experience steady growth over the coming decade, propelled by increasing investments in maritime defense, offshore exploration, and advanced underwater surveillance technologies. According to newly published research, the market was valued at USD 6,186.71 million in 2024 and is expected to grow from USD 6,341.34 million in 2025 to USD 8,348.24 million by 2034, representing a compound annual growth rate (CAGR) of 3.10% between 2025 and 2034.
Sonar (Sound Navigation and Ranging) systems are indispensable for a wide range of underwater applications, from anti-submarine warfare (ASW) and mine detection to marine navigation systems used by commercial vessels and autonomous underwater vehicles (AUVs). This growth is fueled by the expanding naval modernization programs across the globe, as well as by technological advancements in acoustic detection technologies.
Market Overview
Sonar systems are integral to both defense and civilian maritime operations. These systems use sound waves to detect, track, and identify objects underwater, making them crucial for naval operations, submarine tracking, and ensuring the safety of underwater navigation.
The defense sector remains the largest end-user, as nations continue to bolster maritime security in response to rising geopolitical tensions, piracy threats, and the need for enhanced underwater situational awareness. At the same time, the commercial sector is increasingly adopting sonar systems for applications such as hydrographic surveys, fisheries, port security, and oil & gas exploration.
Recent developments in sonar signal processing, AI integration, and unmanned underwater vehicles have further expanded the market scope, enabling real-time imaging, greater depth penetration, and automated anomaly detection.

Market Segmentation
The sonar systems market can be segmented based on type, application, platform, and region. Each segment highlights key areas of technological innovation and user demand.
By Type:
Active Sonar
Passive Sonar
Dual-mode Sonar
Active sonar systems, which emit sound pulses and analyze the returning echoes, dominate the market due to their critical role in object localization and underwater surveillance. However, passive sonar systems, which detect sounds without emitting signals, are also essential, especially for stealth naval operations.
Dual-mode sonar systems—combining both active and passive capabilities—are gaining popularity for their versatility in complex underwater environments.
By Application:
Defense (Naval Vessels, Submarines, Torpedoes)
Commercial (Shipping, Offshore Oil & Gas, Fisheries)
Scientific Research
Port Security
Others
The defense segment accounts for the majority share, driven by heightened interest in anti-submarine warfare and mine detection. Commercial applications, including offshore infrastructure inspection and fish tracking, are also expanding, thanks to growing maritime trade and sustainable fisheries management.
By Platform:
Ship-mounted
Airborne
Torpedo-mounted
Submarine-mounted
Unmanned Underwater Vehicles (UUVs)
Ship-mounted and submarine-mounted sonar systems continue to lead the market, but UUV-mounted systems are expected to see the highest growth rate, reflecting the rapid deployment of autonomous systems in both defense and scientific missions.
Regional Analysis
North America:
North America, led by the United States, holds a significant share of the global sonar systems market due to substantial defense spending and ongoing naval modernization efforts.
