Global Naval Shipbuilding Value Jumps 47% as Submarines and Destroyers Drive Growth.

The assessed value of global naval vessel deliveries jumped 47% in 2024–2025 compared with 2022–2023, while vessel numbers increased just 15%, as naval shipbuilding shifted toward submarines and guided-missile destroyers. Nuclear-powered attack and guided-missile submarine deliveries surged from six to 17, while destroyer deliveries increased from 13 to 24. Together, these categories generated approximately two-thirds of the increase in assessed delivery value.

According to Euronaval’s World Defense Shipbuilding 2026 study, based on Flottes de combat data, assessed delivered-vessel value reached $123.933 billion in 2024–2025, compared with $84.471 billion in 2022–2023. Deliveries rose from 243 to 280 vessels, a 46.7% increase in assessed value and 15.2% in numbers.

The figures show that expensive combat vessels gained weight within global naval construction. For the U.S. Navy and other naval forces, this underscores the importance of undersea warfare, missile firepower, and fleet protection, while raising a procurement question: whether sufficient escorts, patrol vessels, and support ships are being delivered alongside high-end combatants.

Nuclear-powered attack and guided-missile submarines drove the largest growth. Assessed delivery value in the SSN/SSGN category rose from $10.170 billion to $27.370 billion. That $17.2 billion increase accounted for about 44% of the overall $39.462 billion rise, making submarine production the main driver of the shift in the financial balance.

Guided-missile destroyers contributed another $9.020 billion, with assessed value increasing from $16 billion to $25.020 billion. Combined, these destroyers and nuclear-powered attack and guided-missile submarines accounted for 66.4% of the total value increase. Their share of assessed delivery value expanded from 31% to 42.3%, demonstrating a substantial concentration in these two combat categories.

The mechanism matters: average assessed value within each category declined between the periods. Their contribution to growth therefore came from substantially more deliveries, rather than higher average valuations per submarine or destroyer. Across all vessel types, average assessed value per delivery nevertheless increased from approximately $348 million to $443 million because the overall production mix changed.

This 27.3% increase in the fleet-wide average does not establish that an equivalent warship became 27% more expensive. It reflects differences in the types of vessels delivered, their equipment, and national construction costs. The central finding is a shift in the composition of naval shipbuilding output.

Global naval shipbuilding delivery value rose 47% in 2024–2025 versus 2022–2023, while vessel numbers rose 15%.

For U.S. fleet capability, the submarine trend reinforces the importance of both undersea forces and the means to counter them. Nuclear-powered attack and guided-missile submarines can conduct surveillance, threaten ships and submarines, and strike targets ashore where appropriately armed. Additional submarines entering competing fleets can increase the tracking and protection demands placed on U.S. submarines, surface escorts and maritime patrol aircraft.

Guided-missile destroyers provide complementary capabilities, including air defense, anti-submarine protection, anti-ship firepower and land attack, depending on configuration. More destroyers can expand the number of protected naval formations and available missile magazines. Their operational contribution, however, depends on the weapons, sensors and readiness of the ships delivered.

Country-level figures give the global production shift a sharper U.S. context. Chinese shipbuilders delivered 84 vessels totaling 636,208 tonnes, assessed at $45.981 billion, in 2024–2025. U.S. shipbuilders delivered 38 vessels totaling 270,509 tonnes and an assessed value of $26.794 billion. China’s output exceeded the U.S. vessel count and tonnage by more than double, while its assessed delivery value was about 72% higher.

These totals measure production across the study’s military and paramilitary categories, including vessels built for export, rather than deliveries exclusively to either country’s navy. They do not directly measure combat effectiveness, but illustrate the scale of industrial output behind fleet renewal. For U.S. procurement planning, reliable delivery rates matter as much as individual ship performance because they affect replacement capacity and how quickly additional capability reaches the fleet.

Conventional attack submarines also gained weight globally. Deliveries increased from 11 to 18, while assessed value rose from $5.933 billion to $8.546 billion. Across all submarine categories, including strategic submarines, deliveries climbed from 23 to 39 and combined assessed value increased from $20.783 billion to $39.326 billion.

Growth was not uniform across major warship categories. Nuclear strategic submarine deliveries declined from five to three, while aircraft carrier deliveries fell from two to one and their assessed value decreased from $8.2 billion to $6 billion. The aggregate increase therefore reflects concentrated growth in particular vessel types.

Surface escort deliveries expanded more modestly. Guided-missile frigate deliveries increased from 27 to 28, with assessed value rising from $11.824 billion to $13.518 billion. The study’s FS/FFLG category rose from 23 to 27 vessels, while assessed value stayed near $9.4 billion. These figures raise the question of whether escort production is sufficient to distribute protection across shipping routes and naval formations without assigning a destroyer to every mission.

Patrol vessel output presents another contrast. Coastal patrol craft deliveries fell from 40 to 22, while offshore patrol ship deliveries increased from 39 to 48. Combined deliveries declined from 79 to 70 vessels, even as assessed value rose from $4.910 billion to $8.604 billion. Higher-value offshore ships may offer greater endurance and reach, but the lower combined delivery count highlights the difference between per-vessel capability and the number of locations a force can cover.

Replenishment ship deliveries, meanwhile, increased from five to 12, with assessed value rising from $2.230 billion to $4.394 billion. These ships help sustain combat vessels at sea through access to fuel and supplies. Their growth shows that the changing production mix also includes investment in the support needed for extended operations.

For shipbuilders, the unresolved issue is whether expanding submarine and destroyer production constrains affordable escort construction, patrol vessel output or replacement capacity. The global tables do not establish that relationship. It requires evidence on construction slots, skilled labor, shared suppliers and delivery schedules, assessed against retirements and operational demand.

The financial figures have clear boundaries. The study covers purpose-built military and paramilitary vessels exceeding 200 tonnes and counts delivery through the official transfer of ownership. Its values combine published construction and program costs with estimates where necessary, converted into dollars using June 2026 exchange rates. They represent assessed delivery value, not worldwide naval budgets, expenditure during those two years or new orders.

For the U.S. Navy, procurement must balance high-end combat capability with the capacity to sustain it. The global production mix is delivering more submarines and destroyers, but fleet strength also rests on affordable escorts, supporting ships and timely replacements. The 47% rise in assessed value captures a significant industrial shift; its operational value will depend on how those deliveries translate into balanced, deployable forces.
