The U.S. Navy has launched a sweeping modernization plan for its submarine fleet, announcing that 19 advanced attack submarines will be converted into guided-missile platforms as Washington seeks to strengthen its military position against China’s rapidly expanding naval power in the Pacific.

The announcement comes as concerns continue to mount over America’s missile inventory following the conflict with Iran and reflects a broader effort to reinforce U.S. military capabilities in the Indo-Pacific region.

Under the initiative, Virginia-class submarines will be equipped with a specialized payload module approximately 25 meters (84 feet) long, adding 28 new missile launch tubes to the 12 already built into each vessel. The enhanced submarines will be capable of carrying Tomahawk cruise missiles for long-range strikes against land targets, as well as advanced hypersonic weapons designed to penetrate sophisticated Chinese air and naval defense systems.

Military analysts say submarines remain one of the few assets capable of operating undetected close to an adversary’s territory. Sidharth Kaushal, a senior fellow at the Royal United Services Institute in London, explained, “Submarines are one of the few capabilities that can stay near or inside the first island chain in relative safety,” adding that positioning missiles closer to their targets significantly reduces an opponent’s response time.

The overhaul comes as the Navy gradually retires its four aging Ohio-class guided-missile submarines. Those vessels were originally built as nuclear missile submarines before being converted to carry conventional weapons, with each capable of launching up to 154 Tomahawk missiles. Former Navy captain and RAND Corporation researcher Bradley Martin described the Ohio-class boats as “the platform with the greatest capability to launch conventional missile payloads.”

One of those submarines, the USS Georgia, entered the decommissioning process last month, while the remaining three are expected to retire over the next several years. According to the Washington-based Submarine Industrial Base Council, the retirement of the Ohio-class fleet will temporarily reduce the Navy’s undersea strike capability by as much as 60%.

The first upgraded Virginia-class submarines are not expected to enter operational service until 2029, with the final vessel in the program scheduled for delivery in 2038. Despite the temporary decline in firepower, senior Navy leaders have expressed confidence in the transition. Rear Adm. Rob Gaucher, head of the Navy’s submarine programs, said, “These submarines will ensure the Navy continues to dominate the undersea domain for decades.”

Adm. Daryl Caudle, commander of U.S. Fleet Forces Command, said the next generation of submarines will build on the Ohio-class legacy while offering “greater survivability and adaptability.” Analysts note that although each new submarine will carry only about one-quarter of the missile load of an Ohio-class vessel, distributing those weapons across a larger number of submarines will make them far more difficult for China to detect and track.

The move comes in response to China’s accelerated military buildup. Between 2021 and 2025, China’s navy launched 10 nuclear-powered submarines, compared with seven built by the United States during the same period. Over those four years, Beijing also expanded its missile arsenal by approximately 50% and recently unveiled a new unmanned underwater vehicle during a military parade, highlighting its preparations for a potential conflict involving Taiwan.

The Navy’s restructuring also follows the depletion of portions of the U.S. munitions stockpile after the 2025 “Operation Midnight Hammer” strikes against Iran’s nuclear facilities, ordered by President Donald Trump. In announcing the new submarine strategy, the Navy emphasized that “the submarines will operate unhindered in contested waters, ensuring the U.S. Navy maintains absolute undersea superiority.”
