Submarine Combat System Market Report 2026

The submarine combat system market size has grown rapidly in recent years. It will grow from $13.41 billion in 2025 to $15.42 billion in 2026 at a compound annual growth rate (CAGR) of 15%. The growth in the historic period can be attributed to increasing naval modernization programs emphasizing upgraded sonar and fire control systems, rising procurement of diesel-electric and nuclear submarines requiring integrated combat suites, early adoption of digital signal processing to enhance underwater detection accuracy, growth in anti-submarine warfare threats driving investment in advanced navigation and communication systems, expansion of system integration and training services to support complex submarine platforms.

The submarine combat system market size is expected to see rapid growth in the next few years. It will grow to $26.71 billion in 2030 at a compound annual growth rate (CAGR) of 14.7%. The growth in the forecast period can be attributed to rising demand for next-generation submarines equipped with network-centric combat capabilities, increasing adoption of artificial intelligence and automation in submarine combat management systems, development of low-probability-of-intercept sonar and stealth technologies to improve survivability, growing need for interoperable multi-domain warfare systems driving advanced integration services, expansion of simulation-based training solutions to support evolving submarine mission requirements. Major trends in the forecast period include integration of multi-domain combat capabilities, advancements in stealth-centric sensor engineering, growth in modular and upgradeable combat architectures, increasing demand for advanced underwater communication systems, rising focus on high-precision long-range weapon integration.

Rising terrorism is expected to propel the growth of the submarine combat system market going forward. Terrorism refers to acts of violence, intimidation, or destruction conducted by individuals, groups, or organizations with the intent to instill fear, create panic, and achieve political, ideological, or religious objectives. Submarine combat systems detect underwater terrorist attacks to identify potential threats and monitor the activities of enemy ships. For instance, in March 2023, according to a report by the Institute for Economics and Peace (IEP), an Australia-based research organization that develops metrics to analyze peace, the Sahel region in sub-Saharan Africa accounted for 43% of global terrorism deaths. Therefore, rising terrorism is driving the growth of the submarine combat system market.

Key companies operating in the submarine combat system market are increasing their focus on introducing advanced naval communication systems to gain a competitive edge in the market. Advanced naval communication systems refer to sophisticated and high-tech communication technologies designed specifically for maritime operations. For example, in February 2023, Bharat Electronics Limited, an India-based aerospace and defense company, announced it would provide indigenous communication and combat systems for the P-75I submarine. The P-75I submarine is a project initiated by the Indian Navy to acquire six diesel-electric submarines equipped with advanced air-independent propulsion systems. The communication and combat systems installed on the P-75I submarine will be state-of-the-art and fully indigenous. This initiative is part of India's broader effort to modernize its naval fleet and strengthen its maritime security capabilities.

In January 2024, General Dynamics Mission Systems (GDMS), a US-based defense and aerospace company specializing in secure communication and information systems for defense, intelligence, and cybersecurity applications, acquired Progeny Systems for an undisclosed amount. This acquisition enhances General Dynamics' capabilities and improves the U.S. Navy’s operational readiness through advanced technological solutions tailored for modern warfare environments. Progeny Systems, based in Virginia, provides lifecycle support services for U.S. submarines and surface ships.

North America was the largest region in the submarine combat system market in 2025. Asia-Pacific is expected to be the fastest-growing region in the forecast period. The regions covered in the submarine combat system market report are Asia-Pacific, South East Asia, Western Europe, Eastern Europe, North America, South America, Middle East, Africa.

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 submarine combat system market by increasing procurement costs for advanced sensors, electronic support measures, and precision armament components that rely heavily on global supply chains. These tariff-driven cost pressures most significantly affect regions with high import dependency, including Asia-Pacific and parts of Europe, and impact segments such as sonar systems, EW systems, and propulsion-linked combat integration hardware. While the tariffs create challenges by delaying production timelines and raising integration costs, they also encourage domestic manufacturing, supply-chain diversification, and innovation in locally sourced combat system technologies.

A submarine combat system is a comprehensive combination of technologies, equipment, and software designed to facilitate the operational, surveillance, communication, and engagement capabilities of submarines in combat situations.

The primary components of submarine combat systems include sensors, electronic support measures (ESM), and armaments. Sensors are devices or components that detect and measure various physical, chemical, biological, or environmental phenomena, converting them into measurable signals or data. These sensors play a crucial role in identifying potential threats and providing real-time detection underwater through submarine combat systems. They encompass diverse weapon systems, including electronic warfare, torpedoes, ballistic missiles, cruise missiles, and mines, all utilized in various types of submarines such as ship submersible hunter-killer (SSK), ship submersible nuclear (SSN), ship submersible ballistic nuclear (SSBN), and ship submersible guided missile nuclear (SSGN).
