Title: Defense and Security Side Scan Sonar Market Report 2026
Publisher: Research and Markets (Global Market Research Institution)
Release date: January 2026
Interpretation of Industry Trends
According to the latest report released by the international authoritative market research institution Research and Markets, the global defense and security side scan sonar market is experiencing rapid growth. The report predicts that the market size will grow from $800 million in 2025 to $880 million in 2026, with a compound annual growth rate of 8.7%, and is expected to exceed $1.21 billion by 2030.
Core driving factors:
Geopolitical tensions are intensifying: With the increase in global violent incidents and intensifying competition for maritime rights, countries have increased their investment in underwater reconnaissance, anti submarine operations, and port defense. As the core equipment for underwater situational awareness, the strategic value of side scan sonar continues to increase.
Technological iteration acceleration: Synthetic Aperture Sonar (SAS) technology is becoming a new favorite in the market, with significantly better ultra-high resolution underwater imaging capabilities than traditional side scan sonar. In June 2025, Wavefront Systems in the UK launched the Solstice Multi Aperture Sonar (MAS) system, designed specifically for deep-sea AUVs, capable of operating in depths ranging from 1500 to 3000 meters. With ultra-low power consumption and real-time processing capabilities, it can quickly detect mines, leaks, and other underwater anomalies.
Deep integration of unmanned platforms: The integration of sonar systems with AUV/UUV has become a mainstream trend. In July 2025, Deep Ocean Search partnered with Deep Sea Vision to provide integrated AUV and ROV services, combined with advanced side scan sonar capabilities, enabling precise underwater detection, mapping, and monitoring at a depth of 6000 meters.
Industry challenges and responses: The report also points out that the global trade friction has led to increased tariffs on acoustic components and marine electronic components, putting pressure on the production costs of sonar systems. However, this has also stimulated countries to strengthen their local manufacturing capabilities and innovate cost optimization technologies.
Industry significance: This market trend indicates that high-resolution, intelligent, and deeply integrated side scan sonar systems with unmanned platforms are becoming the mainstream direction for future underwater exploration. The demand for high-quality sonar data will continue to grow, whether it is for national defense security or civilian marine engineering, bringing broad opportunities for equipment manufacturers, lessors, and technical service providers.
