Undersea warfare systems market seen reaching $28.51 billion by 2030

The undersea warfare systems market is projected to grow from $21.14 billion in 2025 to $28.51 billion by 2030, driven by higher naval spending, submarine modernization and demand for autonomous underwater systems. North America led the market in 2025, while Asia-Pacific is expected to grow the fastest. Why it matters: - Undersea warfare systems are central to naval defense, protecting underwater borders and countering submarine, mine and other maritime threats. - The market’s growth points to rising defense spending on anti-submarine warfare, sonar, sensors and underwater communications. - The shift toward autonomous and remotely operated systems could change how militaries monitor and secure strategic waters. What happened: - The undersea warfare systems market was valued at $21.14 billion in 2025 and is projected to reach $22.6 billion in 2026. - The market is forecast to climb to $28.51 billion by 2030. - The projected growth rate is 6.9% from 2025 to 2026 and 6.0% over the 2026 to 2030 period. - The Business Research Company published the market outlook on June 12, 2026. - Download a free sample of the market report . The details: - Higher naval spending is supporting purchases and upgrades of submarines, torpedoes, sonar devices and anti-submarine warfare technologies. - Growth is being driven by expanding submarine fleets, improved underwater communication systems and wider use of acoustic sensors and sonar for threat detection. - Modernization of older undersea warfare platforms is also adding to demand. - Future growth is expected to come from autonomous and remotely operated undersea systems, next-generation submarines with better stealth and endurance, and digital undersea communication networks for real-time coordination. - The forecast also points to stronger demand for enhanced acoustic detection, unmanned underwater vehicles, electronic countermeasures, precision mine warfare and advanced data links. - North America held the largest market share in 2025. - Asia-Pacific is expected to be the fastest-growing region in the coming years. - The report covers Asia-Pacific, South East Asia, Western Europe, Eastern Europe, North America, South America, the Middle East and Africa. - View the full undersea warfare systems market report . Between the lines: - The market forecast reflects a broader move by governments to prioritize maritime security amid geopolitical tension. - SIPRI reported in April 2024 that global military spending reached $2.443 trillion in 2023, up 6.8% in real terms from the year before. - That spending backdrop helps explain why underwater defense remains a funding priority. - The report’s focus on unmanned systems suggests militaries are shifting toward lower-risk, more networked undersea operations. What’s next: - Demand is likely to stay supported by military budgets, submarine procurement and modernization programs. - The strongest growth areas are expected in autonomous underwater vehicles, sensing technologies and secure undersea communications. - The company says its 2026 reports include deeper market intelligence, TAM analysis, company scoring matrix graphics, Excel forecasting dashboards and market hotspot infographics. - The Business Research Company says it covers 17,500+ reports across 27 industries and 60+ geographies, with 1,500,000 datasets supporting its forecasts. - The company’s Global Market Model remains its flagship market intelligence platform. The bottom line: - Undersea warfare systems are moving from a niche defense segment into a bigger technology and procurement priority as navies invest in stealthier, smarter and more connected underwater capabilities.
