Submarine Market Size at USD 33.35 Billion by 2031, Industry Size and Share Analysis by Top Key Players | Says Mordor Intelligence

Mordor Intelligence has published a new report on the Submarine Market, offering a comprehensive analysis of trends, growth drivers, and future projections.

Hyderabad, Telangana, India, February 26, 2026 — According to insights from Mordor Intelligence, The global submarine market size is projected to grow from USD 26.39 billion in 2025 to USD 27.44 billion in 2026, and further reach USD 33.35 billion by 2031, registering a CAGR of 3.98% during the forecast period. This steady rise reflects the long procurement cycles and high capital commitments associated with underwater defense platforms. Submarines remain central to naval strategy, offering deterrence, intelligence gathering, and sea control capabilities across major maritime regions. 

The submarine industry is being shaped by nuclear fleet replacement programs, diesel-electric modernization, and steady investments across North America and Asia-Pacific. Although procurement cycles span several years, confirmed defense budgets and intergovernmental agreements support stable order pipelines.

Rising Indo-Pacific maritime tensions and renewed focus on sea-based deterrence are further influencing demand, with established nuclear powers upgrading legacy fleets while emerging navies strengthen conventional submarine capabilities to protect trade routes and territorial waters. 

Market Drivers & Insights in the Submarine Market 

Nuclear Fleet Replacement and Expansion 

One of the strongest drivers in the Submarine Market is the replacement of aging nuclear-powered submarines. Major naval powers are introducing next-generation ballistic-missile and attack submarines to maintain continuous at-sea deterrence. Replacement cycles are structured to avoid capability gaps, ensuring consistent demand for new builds and associated components. 

Indo-Pacific Naval Build-Up 

The Asia-Pacific region is emerging as a central growth engine in the Submarine Market. Countries including China, Japan, India, South Korea, and Australia are increasing fleet sizes or modernizing existing assets. Regional competition and maritime security concerns are pushing governments to strengthen underwater surveillance and strike capabilities. 

Air-Independent Propulsion and Lithium-Ion Integration 

Diesel-electric submarines continue to hold numerical dominance due to affordability and suitability for coastal defense. However, air-independent propulsion systems and lithium-ion battery integration are extending submerged endurance and narrowing the performance gap with nuclear boats.
