Submarine, carrier and cutter contracts are moving forward. So is the work of keeping today's fleet in service. The two draw on different pieces of shipyard capacity, and sometimes on the same people. Here is how to plan for both.
When Navy and Coast Guard shipbuilding makes news, the story is usually about new hulls: a large submarine contract, a new class of icebreaker, a record budget request.
That is one side of the work. The other side gets less attention. Every submarine, carrier, destroyer and cutter already in service needs maintenance, repair and modernization, and many classes also go through major overhaul or service-life extension at planned points in their lives. That work also requires dry docks, waterfront, suppliers and skilled trades.
Both sides are moving at once. In the past year, the Navy has placed 14 new submarines under contract and awarded a contract for another carrier overhaul. The Coast Guard has contracted for 11 Arctic Security Cutters while working through a growing maintenance backlog on cutters that are decades old.
This article looks at how those two workloads relate. The central question for shipyard and marine industry leaders is practical: as programs move forward, how do you plan capacity and workforce for building new vessels and sustaining existing ones at the same time?
The word "accelerate" deserves precision. Based on current evidence, here is what is speeding up and what is not.
So the acceleration is real, but it is concentrated in contracts and funding. That matters for capacity planning, because contracted work becomes yard workload over years, and it arrives on top of the work the existing fleet already requires.
CBO put the relationship plainly in April 2026 testimony:
That is the core idea of this article. Maritime capacity has two sides, and each needs its own kind of capacity:
| New-Construction Capacity | Repair and Maintenance Capacity | Workforce Capacity |
|---|---|---|
| Fabrication and module production | Dry dock and waterfront availability | Skilled trades by craft |
| Assembly and outfitting space | Repair facilities and equipment | Project-specific experience |
| Build positions and launch facilities | Maintenance planning and scheduling | Training and qualification pipelines |
| Production equipment | Modernization and installation capability | Availability by project phase |
| Supplier capability for new components | Subcontractor capability, parts and materials | Ability to shift between projects |
These are not interchangeable. A yard with open dry dock time does not automatically have new-construction capacity, and a new module facility does not add repair capacity. The workforce column connects them, because trades such as welders, shipfitters and pipefitters appear on both sides.
Workforce implication: Before forecasting labor, separate the work into what is being built and what is being sustained. They follow different schedules and use capacity differently.
New construction programs create demand that stretches across years and changes as each hull moves through production.
Navy submarines: contracted and in production. The July 2026 awards cover nine Block VI Virginia-class and five Build II Columbia-class submarines. HII reported that Newport News Shipbuilding will serve as the delivery yard for six of the Virginia-class boats and builds six module sections for each Columbia-class submarine. The same release noted that the contracts include other funding for shipyard infrastructure.
These are multi-year commitments. Work under the new contracts adds to boats already in production, and GAO reported in April 2026 that the lead Columbia-class submarine was at least 18 months behind its contract delivery date.
Navy carriers: in production. HII reported that the future USS John F. Kennedy (CVN 79) reached preliminary acceptance on Sept. 29, 2026, the final step before formal delivery to the Navy.
Coast Guard cutters: several programs at different stages.
New construction requires more than a building way. It depends on fabrication and outfitting space, supplier capability for long-lead components, and a workforce whose craft mix shifts as a ship moves from steel work toward systems installation and testing. GAO reported in April 2026 that "both Navy and Coast Guard shipbuilders face challenges training, recruiting, and retaining trades workers, such as welders, pipefitters, and machinists."
New programs also do not land evenly. A submarine contract affects Groton, Newport News and their suppliers. Cutter awards concentrate along the Gulf Coast. Many other yards will see no direct change.
Workforce implication: New construction demand builds over years and changes by phase. Plan around the production milestones in the contract, not the award announcement.
While new hulls are being built, the ships already in service keep coming back to the yards. That work runs on its own schedule and uses capacity in its own way.
Navy nuclear maintenance: concentrated at public shipyards. CBO testified in April 2026 that the four public naval shipyards "perform nearly all the maintenance on the Navy's nuclear-powered aircraft carriers and submarines, and they have struggled to meet the Navy's goals, particularly those for the attack submarine force." CBO reported that 33 percent of the attack submarine fleet was undergoing or awaiting maintenance, against a goal of no more than 20 percent.
Dry dock capacity is one documented constraint. GAO reported in August 2026 that attack submarines have lost more than 15,000 operational days to maintenance delays over the past decade, and that submarines designated for decommissioning are waiting because shipyards lack the dry dock capacity to begin that process. GAO projected that 15 attack submarines could enter that inactive waiting status from fiscal years 2026 through 2030.
The Navy is rebuilding that capacity, but on a long timeline. GAO reported in September 2026 that new dry docks are under construction at Portsmouth and Pearl Harbor naval shipyards and in final design at Puget Sound, at a combined estimated cost of about $21.7 billion.
Navy surface ship repair: performed largely by private companies. CBO reported in December 2025 that most maintenance for conventional Navy ships is performed under contract at private shipyards. GAO reported that, as of May 2024, 12 companies conducted major repair periods across five fleet concentration areas: Mayport, Norfolk, Pearl Harbor, San Diego and Seattle/Everett.
CBO found that maintenance on destroyers and amphibious ships often takes 20 to 100 percent longer than the Navy's final schedules, with unplanned "new work" and "growth work" among the contributing factors. CBO also found that maintenance and modernization contracts are separate and originate in two different Navy organizations, which can make the two hard to coordinate inside the same availability.
Carrier overhaul: a defined, multi-year event. A refueling and complex overhaul happens once, at the midpoint of a carrier's planned service life. HII describes it as nearly a third of all maintenance and modernization in a carrier's life. The Truman RCOH, awarded in September 2026, covers reactor refueling, modernization across thousands of compartments and tanks, propulsion plant upgrades and combat systems work. HII reported that Truman will be the eighth Nimitz-class carrier to undergo RCOH at Newport News.
Coast Guard sustainment: an aging fleet with growing maintenance needs. GAO reported that, as of January 2025, the Coast Guard operated 241 cutters, some deployed well beyond their design service lives. The Coast Guard deferred about $179 million in cutter maintenance in FY2024, and instances of serious maintenance issues rose 21 percent from FY2018 to FY2023.
The Coast Guard's In-Service Vessel Sustainment program decides class by class which cutters need major maintenance availabilities or service-life extensions. That work is performed at the Coast Guard Yard in Curtis Bay, Maryland, which GAO describes as the service's sole shipbuilding and major repair facility, and at commercial shipyards. Current projects listed by the Coast Guard include:
Recently completed work includes the Polar Star service-life extension, which left dry dock in September 2025.
Workforce implication: Sustainment work is not filler between new builds. It is a defined workload with its own schedule, scope risk and trade requirements.
Not every shipyard does both kinds of work. Some build new ships. Some focus on repair. Some do both. Where both types of work meet, at a single yard or in a single region, they can draw on some of the same resources.
One yard, both workloads. On Sept. 29, 2026, Newport News Shipbuilding announced preliminary acceptance of the new carrier John F. Kennedy and a $5.1 billion contract to overhaul the Harry S. Truman. The same yard is a delivery yard for Virginia-class submarines and a module builder for Columbia-class boats. In a yard like this, new construction and overhaul run side by side, each with its own schedule.
A documented trade-off. In April 2026, the Navy announced it would inactivate the attack submarine USS Boise rather than complete its long-delayed overhaul at Newport News. Chief of Naval Operations Adm. Daryl Caudle said the decision "allows us to reallocate America's highly-skilled workforce to our highest priorities: delivering new Virginia and Columbia-class submarines and improving the readiness of the current fleet." That statement concerns one submarine and one decision. It is still a clear example of new construction and repair drawing on the same skilled workforce.
Dry docks and waterfront. The constraint is not uniform. At the public shipyards, GAO has documented limited dry dock capacity for submarine work. In private surface ship repair, GAO reported that company representatives in every fleet concentration area said "they often had more infrastructure capacity than the Navy was using," while noting that "there is not always sufficient infrastructure capacity available to manage unplanned repair work, such as growth work or emergent repairs." Infrastructure capacity depends on the type of work, the location and whether the work was planned.
Workforce in specific locations. GAO reported that the Navy estimates its planned surface ship repair workload could exceed ship repair companies' workforce capacity in San Diego, Mayport and Pearl Harbor at some times through fiscal year 2031, "if workforce capacity does not change from current levels." That is a location-specific, conditional estimate, not a finding about every repair market.
Workload stability. GAO also reported Navy officials' view that repair workload instability "could result in a reduction of the amount of available workforce as repair companies may reduce the size of their workforce when the workload is projected to dip." Uneven repair schedules can make it harder to keep experienced people in place for the next surge.
Scheduling and contract timing. CBO found that maintenance contracts are sometimes awarded only one or two months before work starts, which gives shipyards "less time to order parts or hire workers." For a yard balancing new-build production with incoming availabilities, short notice on one side affects the other.
Suppliers and subcontractors. Both sides depend on outside suppliers and subcontractors. GAO has reported that many shipbuilding suppliers have their own workforce and infrastructure problems. Repair work also relies on subcontractors for specialized scopes. A prime yard's plan can look balanced while a key subcontractor's does not.
Leaders evaluating capacity can ask: Which of these resources does each project actually use? Where do the same dry docks, crews or suppliers show up on more than one schedule? And which of those overlaps are documented constraints versus risks to watch?
Workforce implication: Where new construction and repair share a yard or region, the overlap is most likely to show up in specialized trades, experienced supervisors and scheduling, not across every resource at once.
Workforce needs can look very different by project type. These are general planning considerations, not industry benchmarks.
| New Construction | Repair / Modernization |
|---|---|
| Multi-year production timelines | Defined availability windows |
| Multiple production phases | Project-specific work scopes |
| Craft mix shifts from structural to outfitting and test | Craft mix depends on the work package |
| Planned workforce ramp tied to milestones | Scope can grow once work begins |
| Supplier lead times for new components | Contract timing can compress hiring windows |
How to use it: Place each upcoming project in one column, then compare the trade peaks. Overlap between columns is where planning attention matters most.
The practical response is visibility. A workforce plan that reflects both sides of the yard starts from the actual work on the schedule.
Start with funded and contracted work. Separate contracted construction, scheduled availabilities and planned modernization from work that is only requested or proposed. The FY2027 shipbuilding request, for example, signals future demand but is not yet workload.
Forecast by trade and by phase. New construction often moves from structural fabrication toward pipefitting, electrical and systems work as outfitting progresses. Repair and modernization scopes vary by ship and availability. A single headcount number hides those differences.
Expect schedules to move. CBO's maintenance findings and GAO's construction findings both show that schedules shift. When an availability runs long or a construction milestone slips, overlap between projects can appear where none was planned.
Watch the shared trades. Welders, shipfitters, pipefitters, marine electricians, machinists and riggers can be needed on both new construction and repair. The experienced leads who supervise them are often the hardest to add.
Give recruiting real lead time. GAO reported that shipbuilder documentation shows it takes 3 to 5 years for an employee to gain proficiency in the skilled trades. Recruiting that begins at contract award or availability start, especially when awards arrive late, leaves little room for qualification and onboarding.
Include subcontractors. Subcontractors and suppliers may have separate workforce requirements and timelines. Their gaps can become the prime yard's delays.
Build in flexibility. A mix of core employees and supplemental craft labor can help a yard scale between construction phases and availability windows without losing the experienced people it depends on.
None of this assumes every yard is overloaded. It means capacity planning has to count the ships already in service along with the ships being built.
Consider your next 12 to 24 months:
New hulls and existing-fleet availabilities run on different clocks and call for different crews. NSC Marine supports shipbuilding, repair, conversion and dry-dock work with skilled trades including welders, shipfitters, pipefitters, electricians, fabricators, firewatch, blaster/painters and riggers. If you are mapping upcoming construction and repair schedules, we can help you think through which trades you will need and when.
EXPLORE MARINE STAFFING REQUEST TALENTShipbuilding capacity covers what a yard needs to build new vessels: fabrication and assembly space, outfitting, production equipment, suppliers and a workforce that changes by production phase. Repair capacity covers dry dock and waterfront availability, repair facilities, maintenance scheduling, modernization capability, subcontractors and parts. They overlap in skilled trades but are not interchangeable.
Mainly contracting and investment. The Navy contracted for 14 submarines in July 2026, and the Coast Guard has contracted for 11 Arctic Security Cutters and received nearly $25 billion under the One Big Beautiful Bill Act. Deliveries on several programs remain behind schedule, according to GAO.
According to CBO, most maintenance for conventional Navy ships is performed under contract at private shipyards, while the four public naval shipyards perform nearly all maintenance on nuclear-powered carriers and submarines. Some private yards that build nuclear ships also perform overhauls, such as carrier RCOHs at Newport News Shipbuilding.
It can, where both share a yard or region. In April 2026, the Navy said inactivating USS Boise would let it reallocate skilled workers to new submarine construction and fleet readiness. GAO has also estimated that planned surface ship repair work could exceed repair companies' workforce capacity in San Diego, Mayport and Pearl Harbor at some times through FY2031 if capacity stays at current levels.
Start with funded and contracted work on both sides, forecast labor by trade and phase, and look for windows where schedules overlap. Because GAO reports skilled trades take 3 to 5 years to reach proficiency, recruiting for shared trades should begin well before construction peaks or availability start dates.
