U.S. Navy Unveils Major Submarine Overhaul to Counter China's Growing Military Threat

The U.S. Navy has announced a major modernization initiative converting 19 advanced attack submarines into guided-missile platforms as it works to strengthen its military position against China's expanding naval capabilities in the Pacific.

The plan reflects mounting concerns over America's missile inventory following conflict with Iran and represents a broader effort to reinforce U.S. Military strength in the Indo-Pacific region.

Virginia-class submarines will receive a specialized payload module approximately 25 meters long, adding 28 new missile launch tubes to the 12 already built into each vessel. The upgraded submarines will carry Tomahawk cruise missiles for strikes against land targets and advanced hypersonic weapons designed to penetrate Chinese air and naval defenses.

Sidharth Kaushal, a senior fellow at the Royal United Services Institute in London, noted that "Submarines are one of the few capabilities that can stay near or inside the first island chain in relative safety," And that positioning missiles closer to targets reduces an opponent's response time.

The Navy is gradually retiring its four Ohio-class guided-missile submarines, originally built as nuclear missile submarines before conversion to carry conventional weapons. Each vessel is capable of launching up to 154 Tomahawk missiles. Bradley Martin, a former Navy captain and RAND Corporation researcher, described the Ohio-class boats as "the platform with the greatest capability to launch conventional missile payloads."

The USS Georgia entered decommissioning last month, with the remaining three expected to retire over the coming years. The Submarine Industrial Base Council warned that Ohio-class retirements will temporarily reduce the Navy's undersea strike capability by as much as 60%.

The first upgraded Virginia-class submarines are expected to enter service in 2029, with the final delivery scheduled for 2038. Rear Adm. Rob Gaucher, head of the Navy's submarine programs, said the vessels "will ensure the Navy continues to dominate the undersea domain for decades." Adm. Daryl Caudle, commander of U.S. Fleet Forces Command, noted the new submarines will offer "greater survivability and adaptability" While building on the Ohio-class legacy.

Between 2021 and 2025, China launched 10 nuclear-powered submarines compared with seven built by the United States. Beijing expanded its missile arsenal by approximately 50% during that period and unveiled a new unmanned underwater vehicle during a military parade.
