Undersea warfare systems market seen reaching $24.8 billion by 2031

The global undersea warfare systems market was valued at $15.8 billion in 2021 and is projected to rise to $24.8 billion by 2031, driven by demand for stealth systems, underwater drones and defense investment. North America led the market in 2021, while Asia-Pacific is forecast to grow the fastest through 2030.

Why it matters: - Undersea warfare is becoming a bigger defense priority as navies invest in stealth systems, unmanned platforms and surveillance tools. - The market’s projected growth signals more spending on submarines, torpedoes, sonar, mine countermeasures and underwater drones. - Defense buyers are also pushing vendors toward systems that can operate farther, deeper and with less human exposure.

What happened: - The global undersea warfare systems market was estimated at $15.8 billion in 2021. - The market is expected to reach $24.8 billion by 2031. - The forecast implies a compound annual growth rate of 3.2% from 2022 to 2031. - Allied Market Research released the report on July 7, 2026. - The report covers market size, share, competitive landscape and trend analysis across type, mode of operation, application and region. - The report includes a 299-page PDF sample download and purchase inquiry links: Download the report sample and request purchase information.

The details: - Demand is being driven by stealth undersea warfare systems, underwater drones and government support for stronger undersea capabilities. - High upfront and operating costs for attack submarines are restraining growth. - Operational complexity in undersea unmanned systems is another barrier. - Lightweight torpedo development and rising defense spending are creating new opportunities. - Increased funding for naval forces, heavy R&D investment and advanced undersea weapons and communications systems are also supporting growth. - Governments and military organizations are awarding contracts for unmanned underwater vehicles, sonar, mine countermeasures and surveillance systems. - The report breaks the market into manned, autonomous and remote operations. - Remote operations are expected to grow at the fastest rate over the forecast period. - Remote systems are used for undersea observation, surveillance, mine warfare and payload delivery. - RE2 Robotics announced in March 2022 that its Maritime Mine Neutralization System reached more than 1 km in open-water testing for the U.S. Navy’s Office of Naval Research. - RE2 Robotics’ M2NS uses RE2 Sapien Sea Class robot arms mounted on VideoRay’s Defender inspection-class remotely operated vehicle. - The system also uses RE2 Detect and RE2 Intellect to support precise, autonomous and clandestine neutralization of a target. - North America held more than two-fifths of the global market in 2021. - Asia-Pacific is projected to post the fastest regional CAGR at 5.7% through the end of 2030. - Europe and LAMEA are also included in the regional analysis. - Key companies in the report include General Dynamic Corporation, Kongsberg Gruppen, Leonardo S.p.A., Lockheed Martin Corporation, BAE Systems Plc., Thales Group, Northrop Grumman Corporation, Raytheon Technologies Corporation, L3Harris Technologies Inc. and SAAB AB. - The listed companies are using partnerships, expansion, collaboration and joint ventures to strengthen their market positions.

Between the lines: - The market outlook points to a shift away from purely crewed platforms and toward systems that blend remote control, autonomy and advanced sensing. - North America’s lead suggests established defense budgets and procurement pipelines remain a major advantage. - Faster growth in Asia-Pacific points to expanding naval modernization and regional security concerns. - The competition appears concentrated among large defense contractors and specialized robotics firms with deep underwater systems expertise.

What's next: - More defense contracts are likely as militaries continue to prioritize underwater surveillance, mine warfare and unmanned operations. - Vendors focused on lightweight torpedoes, UUVs and remote systems may benefit from the strongest demand. - The market’s next phase will likely depend on how quickly operators can reduce cost and complexity in unmanned undersea systems.

The bottom line: - Undersea warfare systems are moving from a niche defense category to a steady growth market, with unmanned and remote technologies driving the next wave of demand.
