U.S. Shipyard Growth Is Driving Marine Industry Demand

U.S. shipyards are being asked to do more of everything. Build more ships. Return ships from maintenance faster. Install new systems on vessels already in service. And in many cases, do all of it in the same yards, with the same skilled trades, during the same months.

The federal signal is clear. The Navy's FY2027 budget request asks for 34 new ships and $65.8 billion in shipbuilding funding. The White House's Maritime Action Plan, released in February 2026, states that the shipbuilding industry "has been experiencing skilled worker and labor shortages" and that current shipyard capacity is not sufficient to scale up domestic shipbuilding.

Investment does not automatically become available workers, though. The more practical question for shipyard leaders is how new construction, repair and modernization each shape labor demand, and what happens when they land on the calendar together.

This article looks at those three demand streams through a workforce planning lens, and offers two quick assessments to help shipyard and marine employers pressure-test their current plans.

What Is Driving Current U.S. Shipyard Activity

Shipyard demand today reflects both ambition and backlog.

On the new construction side, federal policy is pushing for more capacity. The Maritime Action Plan counts 66 U.S. shipyards capable of working on large vessels: eight active shipbuilding yards, 11 yards with build positions, 22 repair yards with drydocking, and 25 topside repair yards. The plan's position is that this base is not large enough to support the scale-up policymakers want.

At the same time, current Navy programs are behind schedule. In an April 2026 report, GAO found that none of the seven shipbuilders constructing Navy battle force ships were positioned to meet the Navy's delivery goals as of February 2025. GAO also reported that Virginia-class submarine construction was running at about one boat per year as of June 2025, half the Navy's goal of two.

On the repair side, the existing fleet needs more maintenance time, not less. CBO reported in December 2025 that the average age of the Navy's conventional ships has increased, and that maintenance periods often run 20 to 100 percent longer than the Navy's final schedules.

The result is a workload that is growing on several fronts and competing for many of the same trades: welders, shipfitters, pipefitters, electricians, riggers, blasters and painters, and the supervisors who lead them.

Workforce implication: Shipyard demand is not one number. Planning works better when new construction, repair and modernization are forecast as separate streams, then combined.

New Construction Is a Multi-Year Workforce Ramp

New construction creates the largest and most sustained labor requirement. It is also the demand stream with the longest runway to plan for.

GAO's February 2025 report on the shipbuilding and repair industrial base cited a DOD estimate that the shipbuilding industrial base will need 174,000 new workers over the next decade to keep pace with Navy shipbuilding goals, accounting for attrition. GAO also reported that several shipbuilders planned to increase the size of their skilled workforce by roughly 80 to 100 percent.

Growth at that scale changes the makeup of a workforce. GAO found that at one shipbuilder, 57 percent of trade workers had fewer than five years of experience, and shipbuilder documentation indicated it takes 3 to 5 years for an employee to gain proficiency in the skilled trades. In other words, a new-build ramp adds headcount quickly, but experience builds slowly.

For workforce planners, that creates a few practical priorities:

• Plan headcount by trade and by build phase, not just a total number for the program.
• Protect experienced workers who lead crews, train new hires and carry quality standards across hulls.
• Account for the proficiency curve when setting productivity expectations for newer crews.
• Budget time for qualification, including weld testing, site safety training and any program or security requirements.

Workforce implication: A new-build program is a multi-year ramp. The planning question is not only how many workers you need, but how many experienced workers you need at each stage.

Repair and Maintenance Work Runs on Its Own Clock

Repair and maintenance create a different type of demand. The work is scheduled around fleet availability, the windows are fixed, and delays have immediate operational consequences.

CBO's December 2025 analysis of Navy ship maintenance found that most maintenance for conventional ships is performed under contract at private shipyards, while most maintenance for nuclear-powered ships is performed at Navy shipyards. CBO also found that late contract awards can limit the time available to plan work and hire workers ahead of an overhaul.

Capacity is already a concern in some locations. GAO reported in February 2025 that 12 companies conduct major repair periods for Navy surface ships, and that the Navy estimates its planned repair workload could exceed ship repair companies' workforce capacity in three fleet concentration areas (San Diego, Mayport and Pearl Harbor) at some times through fiscal year 2031. GAO also noted Navy officials' concern that workload fluctuations in San Diego could reduce the available workforce there.

The public shipyards face their own pressure. In an August 2026 report, GAO found that attack submarine maintenance delays cost the Navy more than 15,000 operational days over a decade, with limited dry dock capacity at the naval shipyards among the constraints.

For repair-focused employers, the workforce challenge is less about building a large permanent headcount and more about having the right trades available for each availability, then keeping them productive if the work runs long.

Workforce implication: Repair demand is spiky and time-sensitive. Plans should account for extensions, growth work and back-to-back availabilities, not only the original schedule.

Modernization Adds Specialized Scope

Modernization is often discussed as part of maintenance, but it creates its own workforce requirements.

According to CBO, modernization work, which adds new systems or capabilities to ships, is typically defined in a separate contract and is not usually performed by the same shipyard doing the maintenance. CBO reported that a Navy official identified poor integration of modernization activities as a key driver of delays and labor overruns.

That has direct workforce implications. Modernization can bring electrical, piping, fitting and systems installation work into a maintenance window that was already tight. It can also mean multiple contractors working in the same spaces, which increases the need for coordination, supervision and clear sequencing.

It is also worth separating ship modernization from shipyard modernization. The Navy's Shipyard Infrastructure Optimization Program (SIOP) is focused on rebuilding dry docks and facilities at the four public naval shipyards. GAO reported in September 2026 that SIOP costs are expected to surpass $200 billion, with planned projects extending past 2080. That is primarily infrastructure construction, but it adds a long-term layer of activity around yards that are also performing maintenance.

Workforce implication: Modernization scope should be forecast by trade and specialty, not folded into general maintenance headcount. Specialized roles are often the ones that are hardest to add late.

When New Construction, Repair and Modernization Overlap

Each demand stream is manageable on its own. The pressure builds when they converge.

A yard or region can see a new-build ramp, a repair availability that runs long, and a modernization package that needs electricians and pipefitters, all within the same quarter. Those projects may be competing for the same local trades, the same supervisors and, in some cases, the same dry dock space.

Overlap tends to show up in a few predictable ways:

• Trade conflicts. Welders, shipfitters, pipefitters and electricians are needed across all three streams.
• Supervision gaps. Adding workers faster than experienced leads can support them affects quality and safety.
• Schedule spillover. A maintenance extension can push into a period already planned for new work.
• Regional competition. Several employers in the same fleet concentration area may be ramping at the same time.

This is where early workforce planning pays off. Leaders who map all three streams on one calendar can see where demand will peak, which trades will be tightest and where supplemental support may be needed, while there is still time to act.

Workforce implication: The time to plan for overlap is before it appears on the production schedule. Once the peak arrives, most of the options are already gone.

Planning the Workforce Before the Workload Peaks

New construction, repair and modernization each put different demands on your workforce. NSC Marine supports shipyards and marine employers across new build, conversion and repair work with skilled trades including welders, shipfitters, pipefitters, electricians, fabricators, blaster/painters, riggers and firewatch.
