How China’s Shipbuilding Boom Is Slowing U.S. Virginia-Class Submarine Production

The United States faces a potential shortage of nuclear-powered submarines amid a decline in the production of Virginia-class vessels, according to industry analyses and defense reports. The slowdown, attributed to a collapse in the domestic shipbuilding industry, has raised concerns about the Navy’s ability to maintain its undersea fleet amid growing geopolitical tensions.

Why is the U.S. submarine production declining?
The Virginia-class submarine program, a cornerstone of the U.S. Navy’s nuclear deterrent, has encountered delays due to a shrinking industrial base. A 2025 report by the Congressional Research Service noted that the number of active shipbuilding yards capable of constructing advanced submarines has decreased by 30% since 2010. This contraction, coupled with workforce shortages and supply-chain bottlenecks, has slowed the delivery of Virginia-class submarines, which are critical for maintaining the Navy’s strategic advantage.

How does China’s shipbuilding capacity factor into the crisis?
China’s rapid expansion of its naval infrastructure has intensified pressure on U.S. defense planners. According to the U.S. Department of Defense’s 2026 annual report, China’s shipbuilding capacity exceeds that of the U.S. by a factor of 2.5, with the People’s Liberation Army Navy (PLA Navy) adding at least 12 new submarines annually since 2020. This disparity has prompted calls for increased investment in U.S. shipyards, though lawmakers have debated the feasibility of scaling up production within the next decade.

What are the implications for U.S. national security?
The potential shortfall in submarine production could weaken the U.S. Navy’s ability to project power in key regions, including the Indo-Pacific. A 2026 study by the RAND Corporation warned that a prolonged gap in Virginia-class deliveries might force the Navy to extend the service lives of older Los Angeles-class submarines, which were designed in the 1980s. “This risks both operational readiness and long-term maintenance costs,” the report stated.

What steps are being taken to address the crisis?
The Biden administration has proposed a $12 billion expansion of shipbuilding infrastructure, including modernization of the Electric Boat and Huntington Ingalls Industries facilities. However, defense analysts note that such projects typically take 5–7 years to complete. Meanwhile, the Navy has accelerated the conversion of existing submarine hulls into Virginia-class variants, a process that could add 3–4 vessels to the fleet by 2028.
