The Navy’s next-generation attack submarine will not materialize for at least 15 years, according to a recent report. The anticipated SSN(X) project, initially set to enter production in 2031, has experienced substantial delays, pushing the timeline back to 2035 and now to 2040. This shift results from rising costs and stringent budget constraints.
In the newly proposed fiscal year 2026 budget, the Navy has requested $623 million to advance the SSN(X) program. This class of submarines is designed to enhance capabilities in stealth, intelligence gathering, larger torpedo payloads, and advanced communication with unmanned undersea systems.
Despite its potential, the report has sparked concerns among lawmakers regarding the implications of such delays on the United States’ undersea dominance. There is apprehension that prolonged timelines could hinder the Navy’s ability to carry out vital missions effectively.
Weighing in at approximately 10,000 tons, the SSN(X) is projected to incur costs ranging from $6.7 billion to $8 billion per submarine. This places it significantly above the Virginia-class submarines, which have been in service since 1998 and each costs about $4 billion. Although the Navy aims to procure two Virginia-class submarines annually, actual production has slowed to an average of 1.2 to 1.4 per year. This has led to a growing backlog of submarines that have been funded but remain unconstructed.
For fiscal year 2025, the Navy plans to request only one new Virginia-class submarine due to these persistent production hurdles. It has become clear that only two shipyards in the U.S., Electric Boat and Newport News, currently possess the capabilities required to build nuclear-powered submarines.
The report also advises lawmakers to evaluate the impact of delaying production on the submarine industrial base. Questions arise regarding whether transitioning from highly enriched uranium reactors to low-enriched uranium could provide cost or safety benefits.
In an ambitious move, the Navy intends to expand its fleet from 296 to 381 ships in the coming decades. However, experts caution that such major industrial growth will be crucial to meet these objectives. Brett A. Seidle, acting assistant secretary of the Navy for research, development, and acquisition, highlighted the pressing challenges during a Senate Armed Services Committee hearing.
Seidle stated, “We need more ships delivered on time and on budget, and we are challenged in both arenas.” He further emphasized the rising costs, which are escalating faster than inflation, alongside delays affecting numerous programs ranging from one to three years.
Despite nearly doubling its shipbuilding budget over the last two decades, the Navy continues to fall far short of its ship-count aspirations. The Government Accountability Office has pointed out that Navy shipbuilding programs and shipyards are stuck in a “perpetual state of triage.”
Last month, Rep. Rosa DeLauro, the leading Democrat on the Appropriations Committee, queried Defense Secretary Pete Hegseth about his strategic plans to expand shipbuilding capacity. Her demand for a written plan highlights the urgency of addressing these delays.
In her remarks, she stated, “I want your plan. Can we get that in writing and on paper? Because we don’t have anything today – zip, nada.”
In response, Hegseth acknowledged, “We have the details, and we will provide them.” This exchange underscores the heightened pressure on Navy officials to articulate a clear, actionable strategy as the delays continue to raise critical concerns.
With the Navy’s next-generation submarine program now facing an alarming delay until 2040, stakeholders must carefully monitor developments and advocate for viable solutions. The complexities involved with the SSN(X) program reflect broader issues within U.S. naval readiness and industrial capacity.
As discussions continue, the focus remains on how to ensure the future efficiency and effectiveness of the Navy’s submarine fleet. Thus, the implications of these delays could reverberate through multiple facets of military strategy and national security.
In the coming months and years, all eyes will be on the Navy’s response to these challenges and whether appropriate measures can be implemented to prevent further setbacks in submarine production and overall fleet expansion.
