US Navy Cancels Biden-Era Submarine Contract as Overhaul Costs Approach $3 Billion

On April 10, 2026, Navy Secretary John Phelan confirmed what defense analysts had expected for months: the USS Boise (SSN-764), a Los Angeles-class nuclear attack submarine commissioned in 1992, will be permanently inactivated [1]. The vessel has not operated at sea since 2015, lost its dive certification in 2017, and consumed nearly $800 million in taxpayer funds while sitting in a Virginia shipyard with only 22% of its scheduled overhaul work completed [2].

"We screwed up. We did. This doesn't look good. It is what it is. Time to move on," Phelan told Semafor [3].

The decision kills a $1.2 billion engineering overhaul contract awarded to Huntington Ingalls Industries' Newport News Shipbuilding division in February 2024 — a contract that was itself nine years behind schedule when it was signed [4]. Had the Navy stayed the course, total lifecycle costs for the Boise overhaul were projected to approach $2.7 billion, with completion unlikely before 2029 at the earliest [1][2]. The submarine would have returned to service with roughly 20% of its operational life remaining — enough for approximately three deployments [1].

The Contract: A Decade of Delay

The Boise's overhaul was originally scheduled to begin in fiscal year 2016 at Norfolk Naval Shipyard, one of four public shipyards that handle nuclear submarine maintenance [4]. But Norfolk was consumed by higher-priority work: ballistic missile submarine refuelings and aircraft carrier repairs. The Boise was effectively placed in a queue that never moved.

In 2018, the Navy transferred the Boise to HII's Newport News Shipbuilding in an effort to break the logjam, paying $351.8 million in initial planning and preparatory work [4]. Newport News had not performed a submarine overhaul in over a decade and needed years to reconstitute its submarine repair capabilities [4]. The work never started in earnest. By 2021, the Chief of Naval Operations stated the overhaul would begin "soon" — it did not [4].

The formal $1.2 billion contract was finally awarded on February 23, 2024, covering "maintenance and restoration of the ship's hull structure, tanks, propulsion systems, electric plant, auxiliary systems, armament and furnishings, as well as numerous ship alterations" [4]. The contract estimated completion by September 2029 — fourteen years after the Boise's last deployment.

What Drove Costs Toward $3 Billion

The Boise's cost explosion was not caused by a single failure but by compounding problems that were largely foreseeable at the time of contract award.

Deferred maintenance compounding. The longer a nuclear submarine sits idle, the more its systems degrade. Rubber seals, gaskets, and pipe linings deteriorate. Electronics corrode. By the time work began in earnest, the scope of repairs had expanded far beyond the original engineering estimates [5][6].

Labor shortages. The submarine industrial base faces a structural workforce crisis. The Navy needs to hire 100,000 new skilled trade workers over the next decade [7]. At HII's shipyards, 57% of trade workers have fewer than five years of experience, requiring more supervision and producing more rework [7]. The Navy's recruiting pipeline for shipyard workers loses more than half of new hires within their first year, largely because wages cannot compete with private-sector manufacturing and service jobs [8].

Supply chain failures. Specialized submarine components are produced by a narrow base of suppliers, many of whom face their own workforce and capacity constraints. Delays in material delivery cascaded through the project timeline [9].

Cost-plus contract structure. The Boise overhaul, like much of the Navy's maintenance work, operated under cost-plus contracting, where the government reimburses a contractor for all allowable costs and then pays an additional fee for profit. This structure, as the Government Accountability Office has documented repeatedly, creates weak incentives for contractors to control costs. Under cost-plus arrangements, companies are reimbursed for escalating expenses, and hours spent on tasks "magically inflate once the work starts," as Breaking Defense described the dynamic [10]. The GAO has found that the Department of Defense paid an estimated $8 billion in award and incentive fees across contracts "regardless of whether acquisition outcomes fell short of, met, or exceeded DOD's expectations" [11].

Reconstituting lost capability. Newport News Shipbuilding had a ten-year gap in submarine overhaul work before taking on the Boise. Rebuilding institutional knowledge and tooling took years and added cost [4].

HII's Track Record

Huntington Ingalls Industries is one of only two companies in the United States that build nuclear-powered submarines, alongside General Dynamics Electric Boat. Together, they have built and delivered 24 Virginia-class submarines [12]. HII's Newport News division has completed refueling and complex overhauls on six Nimitz-class aircraft carriers and is currently working on a seventh [12].

But the company's submarine work has faced consistent challenges. Virginia-class production runs at roughly 60% of its annual goal, years behind schedule, due to workforce and capacity constraints [7]. HII CEO Chris Kastner acknowledged in late 2025 that existing submarine funding approaches were "insufficient to get boats the Navy wants" [13].

In response to the Boise cancellation, HII spokesperson Todd Corillo stated the company anticipates "no impact to our workforce and will transition shipbuilders currently assigned to USS Boise to other work underway at Newport News Shipbuilding" [6]. This is a significant claim: HII is currently engaged in Virginia-class and Columbia-class construction work, and the workers freed from the Boise project represent scarce skilled labor the company needs elsewhere.

The Math: Overhaul vs. New Build

The Boise's projected $2.7 billion overhaul cost demands comparison with other options. A typical Los Angeles-class Engineered Refueling Overhaul costs roughly $400 million [14]. A new Virginia-class submarine costs approximately $5 billion under the Navy's FY2026 budget submission [15]. A Columbia-class ballistic missile submarine — a different mission set entirely — runs about $10.5 billion [6].

The Boise overhaul would have cost roughly 65% of a new Virginia-class submarine, according to Fox News reporting, yet would have returned a 1990s-era boat with limited remaining service life [1]. A new Virginia-class submarine offers 33 years of service and significantly greater capability. By that arithmetic, the Navy's decision to walk away looks less like waste and more like triage.

For international comparison, nuclear submarine refueling and overhaul costs for allied navies provide limited benchmarks. UK Astute-class and Trafalgar-class submarines use highly enriched uranium reactors that do not require mid-life refueling, reducing their overhaul complexity [16]. France's Rubis-class and Suffren-class submarines use low-enriched uranium reactors that require refueling approximately every ten years, a process that takes about six months and costs significantly less than a full American ERO [16]. Neither the UK nor France has experienced overhaul cost escalation at the scale of the Boise.

Fleet Readiness: The Operational Toll

The Boise's inactivation removes one attack submarine from the Navy's nominal order of battle, but the vessel has been operationally useless since 2015. The real question is what the decision signals for the broader fleet.

The Navy currently has 17 fast-attack submarines in public shipyards [17]. Attack submarine idle time — the days submarines spend waiting to enter maintenance or delayed in completing it — has escalated sharply over the past decade. From fiscal year 2016 through fiscal year 2025, inactive attack submarines accumulated 3,287 days of idle time, peaking at 1,260 days in FY2025 alone [18]. Without mitigation, the GAO projects 15 attack submarines will enter inactive idle time through fiscal year 2030, accumulating more than 14,000 idle days [18].

The Navy spent $4.2 billion on attack submarines sitting idle between FY2016 and FY2025 — paying crews, maintaining pier-side infrastructure, and supporting boats that could not deploy [18]. Chief of Naval Operations Admiral Daryl Caudle described the maintenance situation as "like a dagger in the heart" for the submarine force [1].

The Navy's goal is to have 80% of its fleet ready to deploy by 2027, a target that requires strict adherence to maintenance schedules [19]. Canceling the Boise does not directly worsen this metric — the boat was never going to be available by 2027. But it does reduce the total number of attack submarines the Navy can field in the 2030s, at a time when China's submarine fleet continues to grow.

Two additional Los Angeles-class boats — USS Newport News (SSN-750) and USS Alexandria (SSN-757) — are also scheduled for inactivation in 2026 and will be scrapped at Puget Sound Naval Shipyard [20].

The Workforce Question

The Navy plans to redirect workers from the Boise project to Virginia-class and Columbia-class submarine construction [3][6]. This is consistent with broader industrial strategy: the FY2027 budget request includes $11.4 billion for two Virginia-class submarines and $10.5 billion for one Columbia-class submarine [6].

HII's assertion that no workers will be laid off is plausible given the scale of competing demands for skilled submarine labor. Newport News currently employs approximately 25,000 workers, and the facility is engaged in carrier and submarine work simultaneously [12]. The constraint on submarine production has never been too many workers — it has been too few.

The broader shipyard workforce picture remains difficult. The Navy is investing nearly $1 billion in automated manufacturing facilities designed to produce submarine parts faster and with fewer workers [7]. The Shipyard Infrastructure Optimization Program, a multi-decade effort to modernize the four public naval shipyards, continues with contracts like a $377 million upgrade to Dry Dock 4 at Puget Sound [18].

The Case for Cancellation as Fiscal Discipline

The strongest argument for the Navy's decision is the simplest: finishing the Boise would have rewarded a broken system.

Cost-plus contracting has a documented history of insulating contractors from the consequences of cost growth. The GAO has repeatedly found that DOD pays billions in incentive fees without regard to whether contracts meet their cost or schedule targets [11]. Completing the Boise overhaul — spending an additional $1.9 billion to recover a submarine that would serve for a few more years — would have set a precedent that there is no cost threshold at which the Navy will walk away from a failing project.

"By killing these programs, it's sending a message that we're not going to continue to send good money after bad investments," Phelan said [3].

This framing has supporters. Defense reformers have long argued that the Pentagon's unwillingness to cancel troubled programs creates a moral hazard: contractors and program offices know that once spending passes a certain threshold, political inertia will carry the project to completion regardless of performance. The Boise cancellation breaks that pattern.

Critics counter that the cancellation penalizes the wrong party. The submarine sat idle for nearly a decade not because HII failed to perform, but because the Navy's public shipyards could not accommodate it. By the time the contract was awarded in 2024, costs had already ballooned due to the Navy's own scheduling failures. Canceling the contract after the fact does not address the root causes — underfunded shipyard capacity and chronic workforce shortfalls — that created the problem [4][5].

Accountability and the Revolving Door

The officials who presided over the Boise's decade of drift span multiple administrations and Navy leadership teams. The submarine's overhaul was originally deferred during the Obama administration, remained stalled through the first Trump administration, was contracted during the Biden administration, and has now been canceled during the second Trump administration. No single official bears responsibility for the cumulative failure.

Navy Secretary Phelan, who made the cancellation decision, comes from the private equity world rather than the defense establishment. He co-founded MSD Capital, which manages the wealth of Michael Dell, and holds investments worth over $50 million in Dell Technologies — a company with a $2.5 billion Navy contract [21]. Senator Elizabeth Warren raised concerns about Phelan's potential conflicts of interest during his confirmation process, urging him to divest defense contractor holdings [21]. Phelan was confirmed by the Senate 62-30 in March 2025 [21].

The broader pattern of defense industry revolving doors remains intact. A 2023 Project on Government Oversight investigation found that hundreds of senior Pentagon officials move to defense contractor positions after government service, and vice versa [22]. Whether any officials involved in the Boise's contract decisions have made such transitions is not publicly documented.

The Golden Fleet and What Comes Next

The Boise cancellation arrives as the Trump administration pursues the most aggressive naval expansion since the Cold War. The FY2027 budget request of $65.8 billion for shipbuilding represents a 242% increase over FY2026 levels, funding 18 battle force ships and 16 support vessels [23]. The administration's "Golden Fleet" initiative, announced by President Trump in December 2025, envisions a new class of battleships armed with lasers and hypersonic missiles, alongside expanded frigate and unmanned vessel production [23].

The tension is obvious: the Navy cannot maintain the fleet it has, yet is proposing to build a dramatically larger one. The Boise is a casualty of this gap between ambition and industrial capacity. Whether the Golden Fleet's shipbuilding surge will strain the same workforce and supply chains that failed the Boise — or whether the massive budget increase will finally expand capacity enough to break the cycle — remains the central unanswered question in American naval policy.

Admiral Caudle called the Boise decision "a tough but necessary decision" that would allow the Navy to prioritize delivery of Virginia and Columbia-class submarines [6]. The math supports him. But the $800 million already spent on the Boise — money that bought 22% of an overhaul on a submarine that will never sail again — stands as a measure of what the Navy's maintenance crisis has cost and continues to cost the United States.
