Anti-Submarine Warfare Systems Market Report 2026

The anti-submarine warfare systems market size has grown strongly in recent years. It will grow from $18.44 billion in 2025 to $19.59 billion in 2026 at a compound annual growth rate (CAGR) of 6.3%. The growth in the historic period can be attributed to increasing naval modernization programs driving procurement of fixed-wing aircraft and air-dropped asw weapons, rising geopolitical tensions boosting demand for submarine detection and tracking capabilities, advancements in underwater acoustics enhancing performance of sonobuoys and training targets, expansion of manufacturer-provided warranty-period maintenance and operational support services, historical growth in maritime patrol aircraft fleets supporting broader deployment of asw systems.

The anti-submarine warfare systems market size is expected to see strong growth in the next few years. It will grow to $24.2 billion in 2030 at a compound annual growth rate (CAGR) of 5.4%. The growth in the forecast period can be attributed to growing adoption of next-generation asw platforms integrating multi-sensor detection technologies, increasing procurement of advanced sonobuoys to counter quieter and more capable submarines, rising demand for long-range maritime patrol aircraft supporting expanded asw coverage, expanding investment in unmanned systems for anti-submarine surveillance and engagement, expected growth in integrated lifecycle service packages including system upgrades, data analytics, and predictive maintenance for asw systems. Major trends in the forecast period include increasing deployment of long-range air-dropped asw weapons, rising demand for advanced sonobuoys for wide-area submarine detection, enhancement of maritime patrol aircraft with upgraded asw mission suites, growing adoption of training targets for naval asw exercises, expansion of multi-platform asw integration across ships, aircraft, and submarines.

The rising defense budgets are expected to drive the growth of the anti-submarine warfare (ASW) systems market going forward. A defense budget, or defense spending, refers to the financial resources allocated by a state to raise, maintain, and equip its armed forces. The increase in defense spending supports the advancement of ASW systems by providing essential funding for research, development, procurement, and operational deployment of technologies designed to counter submarine threats and maintain maritime superiority. For instance, in February 2025, according to the International Institute for Strategic Studies (IISS), a UK-based international research institute, global defense spending reached a record high of $2.46 trillion in 2024, representing a 7.4% increase from the $2.24 trillion spent in 2023. Therefore, rising defense budgets are fueling the growth of the anti-submarine warfare (ASW) systems market.

Prominent entities within the anti-submarine warfare system domain are actively engaged in the development of cutting-edge technologies, including anti-submarine torpedoes, aimed at mitigating evolving submarine threats and bolstering maritime security. Anti-submarine torpedoes, specifically engineered to incapacitate or destroy submarines, stand as a pivotal component in this endeavor. Notably, in September 2023, BAE Systems, a UK-based provider of defense, aerospace, and information security solutions, in collaboration with Malloy Aeronautics, a UK-based manufacturer of military drone systems, unveiled an inert variant of the Sting Ray training anti-submarine torpedo. Distinguished by its electric-powered vertical take-off and landing capabilities, this anti-submarine torpedo boasts a payload capacity of up to 200kg, speeds reaching 140 km/h, and an operational range of 80km, contingent upon payload specifications. Additionally, its design facilitates easy disassembly for transportation, with dimensions akin to those of a small car.

In July 2023, Thales Defense & Security Inc., a prominent French manufacturer specializing in electrical systems, finalized the acquisition of Advanced Acoustic Concepts (AAC) for an undisclosed sum. This strategic move enables TDSI to broaden its footprint in the US defense sector by enhancing its engineering and industrial capacities. The acquisition entails reinforcing TDSI's US operations and capabilities leveraging AAC's expertise. Advanced Acoustic Concepts LLC, based in the United States, is recognized for its provision of advanced anti-submarine warfare systems.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

Tariffs are impacting the anti-submarine warfare systems market by increasing the cost of imported components such as sonar modules, electronic support hardware, propulsion elements, and advanced materials used in ASW platforms. These higher input costs are particularly affecting segments like sensors, armament, and unmanned systems, with regions in Asia-Pacific and Europe facing the strongest supply chain disruptions. However, tariffs have also encouraged domestic production, technology localization, and government-backed naval modernization, generating new opportunities for regional manufacturers.
