Underwater warfare market seen doubling to $54.76B by 2035

A new industry analysis says the global underwater warfare market will grow from $26.01 billion in 2024 to $54.76 billion by 2035, driven by autonomous systems, advanced sonar and rising defense spending. North America leads today, while Asia-Pacific is the fastest-growing region as navies invest in undersea dominance.

Why it matters: - The global underwater warfare market is projected to nearly double by 2035 as militaries expand spending on submarines, underwater drones, sonar and secure communications. - The shift reflects rising concern over undersea threats, including contested shipping lanes, submarine activity and asymmetric tactics such as mines and underwater drones. - The market also shows how defense priorities are broadening from traditional platforms to autonomous systems and AI-enabled sensing.

What happened: - Industry analysis estimates the market will rise from US$ 26.01 billion in 2024 to US$ 27.83 billion in 2025 and then reach about US$ 54.76 billion by 2035. - The forecast implies a compound annual growth rate of about 7.0% from 2025 through 2035. - Market Research Future released the analysis on Sept. 1, 2026. - The report covers technologies used to detect, deter and engage threats beneath the waves, including unmanned underwater vehicles, sonar arrays, electronic warfare suites, torpedoes, weapons systems and secure communications. - A free sample of the report is available online.

The details: - Global defense spending is expected to approach $2 trillion within the next couple of years, and a growing share is flowing into undersea capabilities. - Artificial intelligence and machine learning are changing how navies process sonar data, gather intelligence and make tactical decisions. - Autonomous underwater vehicles are now being used for reconnaissance, mine countermeasures and surveillance. - Environmental concerns are pushing navies and shipbuilders toward quieter propulsion systems and more sustainable manufacturing. - NATO members and allied nations are increasing joint exercises, technology-sharing and co-development programs. - By system, unmanned systems hold the largest market share. - Sonar systems are the fastest-growing system segment. - Weapons systems are projected to approach about $15 billion by the end of the forecast period. - Communications systems are expected to reach about $7.8 billion by 2035. - Unmanned systems are projected to reach roughly $11 billion by 2035. - By capability, support functions hold the largest share today. - Attack capabilities are the fastest-growing capability segment and are on pace to approach about $22 billion by 2035. - By platform, submarines remain the dominant segment and are expected to reach about $17.76 billion by 2035. - Surface ships are the fastest-growing platform category. - Naval helicopters remain a smaller but important surveillance and reconnaissance platform.

Between the lines: - North America holds about 45% of global market share, supported by large defense budgets and a mature industrial base. - Europe accounts for about 30% of the market, helped by NATO collaboration and European Defense Fund funding. - Asia-Pacific holds about 20% of the market but is growing the fastest as China, India, Japan and others raise spending and expand domestic production. - The Middle East and Africa account for about 5% of global share, with the UAE and South Africa among the notable investors. - The competitive field includes Lockheed Martin, Raytheon Technologies, Northrop Grumman, Thales Group, BAE Systems, Leonardo, General Dynamics, Kongsberg Gruppen and Saab AB. - Competition is shifting toward integrated systems, supply chain reliability and localization rather than price alone. - Companies are also forming cross-border technology-sharing agreements to speed development.

What's next: - The report expects continued investment in autonomous underwater vehicles, AI-driven analytics and secure underwater communications through 2035. - Navies are likely to keep balancing offensive and defensive spending as maritime security risks rise. - Further regional growth appears most likely in Asia-Pacific, where defense budgets and indigenous manufacturing are expanding. - More reports, electronic warfare aircraft market and anti-submarine warfare market are also listed by the publisher.

The bottom line: - Undersea warfare is moving from a niche naval capability to a core defense priority, and the spending outlook points to sustained growth over the next decade.
