Billions: What Exactly Does the Navy Get?
USS Harry S. Truman is entering the one overhaul that determines whether it serves roughly 25 years or more than 50.
Five billion dollars sounds like the price of another warship. On a Nimitz-class carrier, it is the price of taking a 101,000-ton nuclear airfield apart deeply enough to prepare it for another quarter-century at sea. USS Harry S. Truman will have its reactors refueled, propulsion plant rebuilt and modernized, hull and underwater machinery repaired, communications and combat systems replaced, electronic warfare and self-defense systems upgraded, and thousands of compartments, tanks and ship systems inspected or renewed. The headline shipyard contract is $5.1 billion. The Navy's broader budget estimate is closer to $6.8 billion. When the work ends in 2031, the objective is not to return the same carrier. It is to return a 1998 hull able to fight into the late 2040s and beyond.
The $5.1 billion headline is not the whole bill
The largest bill is still the physical rebuild
FY2026 Navy Shipbuilding and Conversion budget estimate for CVN-75. Percentages are calculated from the $6.809632 billion total ship estimate.
The overhaul starts with the reason the ship can serve another 25 years
This is not normal carrier maintenance
The nuclear refueling happens only once during a Nimitz-class carrier's expected service life.
Without it, the ship does not simply operate at reduced capability. It cannot remain in service for the second half of the roughly 50-year design life.
The shipyard rebuild reaches the machinery that actually moves 101,000 tons
A 1998 carrier gets a 2030s combat-system baseline
| System area | CVN-75 RCOH budget baseline | What changes operationally |
|---|---|---|
| Command + communications | C4ISR and ICAN / DDCN / IVCN | Modern digital communications, data distribution and command-network infrastructure. |
| Ship self defense | SSDS Mk 2 Mod 1E | Updates the carrier's integrated detect, track and engagement architecture. |
| Electronic warfare | SEWIP Block III | Adds modern electronic detection and active electronic-attack capability. |
| Cooperative engagement | AN/USG-2B CEC | Allows the carrier to participate in a distributed sensor and engagement network. |
| Surface search | AN/SPS-73 NGSSR | Modernizes surface-search and navigation detection capability. |
| Air traffic control | AN/SPN-50(V)1 | Updates carrier aviation air-traffic-control radar infrastructure. |
| Landing support | AN/SPN-46 overhaul / upgrade + SSLS | Modernizes aircraft approach and landing support systems. |
| Combat direction | CDC / Flag ripout and installation | Rebuilds spaces and systems used to command the carrier and wider strike group. |
| Undersea warfare | AN/SQQ-34C Carrier Tactical Support Center | Updates the carrier's contribution to ASW and undersea situational awareness. |
Self-defense systems are part of the recapitalization
Rebuild the existing carrier or buy another one?
Truman RCOH
New Ford-class carrier
Truman's overhaul is about 45% of the current CVN-81 cost estimate
That does not mean a refurbished Nimitz is 45 percent of a Ford carrier. The Ford class offers newer propulsion, electrical generation, EMALS, Advanced Arresting Gear, greater sortie potential, larger future growth margins and lower intended life-cycle manpower burden.
But replacing Truman rather than refueling it would require funding an entirely new nuclear carrier while losing an existing hull decades before its potential service life is exhausted.
The Navy almost chose retirement instead
The schedule is part of the price
A carrier in RCOH may still exist on the Navy's books, but it is not available for normal deployment. That makes schedule slip strategically expensive even before additional shipyard costs are counted.
Do not compare $2.8B, $3B and $5.1B as if they are complete carrier costs
| Carrier | Execution contract announced | Known outcome / current estimate | What the comparison teaches |
|---|---|---|---|
| USS George Washington | $2.8B in 2017 | 69-month RCOH | The original shipyard award was not the only program cost incurred over a long availability. |
| USS John C. Stennis | ~$2.9B to $3.0B in 2021 | FY2026 total ship estimate ~ $7.19B | Cost growth, government-furnished equipment and completion funding make the total much larger than the original execution contract. |
| USS Harry S. Truman | $5.10B in 2026 | FY2026 total ship estimate ~ $6.81B | The execution contract itself now captures a larger share of the expected work and uses a different incentive structure. |
The surprising number is Stennis
The Navy's FY2026 ship-cost table estimates the total CVN-74 RCOH at roughly $7.19 billion, even though its original HII execution contract was announced at around $3 billion.
That is why Truman's $5.1 billion award should not automatically be described as a 70-plus-percent increase in the cost of refueling a carrier. Contract structures, government-furnished equipment, schedule growth and allocation of work differ.
The Navy rebuilt its cost model before Truman arrived
Million hours in the old planning model
Earlier Navy cost models used approximately 21.7 million labor hours for a notional RCOH execution.
Million hours in actual recent experience
The Navy's FY2025 budget said actual invoices from CVN-71 through CVN-73 averaged roughly 26.5 million hours.
The planning assumption had been too low
The difference helps explain why later budgets and contract structures have had to acknowledge a larger labor requirement.
The Navy is trying not to spend a million sailor-hours painting the shipyard
Beginning with Truman, the Navy is shifting more non-rate-specific RCOH work to commercial contracts rather than using assigned sailors for tasks such as painting, insulation, transportation and general maintenance support.
Truman also enters RCOH with unfinished combat-deployment damage
In February 2025, Truman collided with merchant vessel Besiktas-M near Port Said. The carrier remained mission capable and resumed operations after emergent repairs.
The Navy later said complete repair of the collision damage would be carried out during the upcoming RCOH.
The same hull, but not the same combat system
Second-half nuclear life
Refueled reactors and overhauled propulsion equipment restore the machinery base needed for another quarter-century of operations.
Material condition reset
Corrosion treatment, tanks, underwater machinery, steering components and distributed HM&E systems receive a deep reset.
Modern C4ISR architecture
Communications, data distribution and combat-system infrastructure move much closer to the standards of the fleet operating in the 2030s.
Newer electronic warfare and self-defense
SEWIP, RAM, CIWS, SSDS and Cooperative Engagement Capability improve the carrier's ability to detect, share and respond to threats.
Updated control and landing systems
Modernized air-traffic-control and landing-support systems allow the ship to support a carrier air wing far newer than the one it operated in 1998.
Rebuilt combat and flag spaces
The carrier remains not only an airfield but a command node for the entire carrier strike group.
The output is a hybrid of two eras
The hull, steam catapults and fundamental Nimitz architecture remain.
The reactors, machinery, networks, sensors, electronic warfare and combat-management systems are refreshed around them.
That is the central logic of RCOH: keep the enormously expensive nuclear hull and replace enough of everything inside it that the Navy can keep treating it as a front-line carrier.
Twenty-five years of carrier force structure
One nuclear carrier hull retained
The alternative to RCOH is not operating the same ship without modernization. Eventually it is retirement.
One carrier air wing's sea base retained
Keeping Truman preserves another deck from which fighters, airborne early warning aircraft, helicopters and future unmanned aircraft can operate.
Industrial knowledge retained
Newport News remains the only shipyard capable of performing nuclear aircraft-carrier RCOH work.
Replacement construction deferred
Retaining Truman lets Ford-class construction replace older Nimitz carriers in sequence rather than filling an early hole created by CVN-75 retirement.
Carrier RCOH Economics + Schedule Stress Test
Compare the cost of extending a Nimitz-class carrier with the capital cost of a new carrier, then test how schedule slip changes the economics. Delay cost is deliberately user-adjustable because there is no single public monthly cost applicable to every RCOH delay.
