A recent study has raised alarms about the potential threat posed by advanced Chinese submarines to the United States’ underwater dominance. The study, released on November 14, 2025, underscores the rapid advancements in Beijing’s naval capabilities, including a breakthrough in submarine tracking technology that exploits a weak spot in U.S. submarines. These developments signify an escalating competition in underwater warfare, where detection technologies and stealth features play a crucial role in maintaining strategic balance.
Overview of the Threatening Study
The study, titled “Advanced Chinese Submarines Could Threaten U.S. Underwater Dominance, Study Warns,” presents a comprehensive assessment of China’s submarine fleet, which it views as a direct challenge to American naval superiority. The study integrates data on Chinese submarine advancements, projecting potential risks to U.S. underwater dominance. It also highlights specific warnings about the implications for global maritime security, linking these developments to the broader context of Sino-U.S. rivalry.
Released on November 14, 2025, the study is a timely analysis of the escalating competition in underwater warfare. It underscores the rapid advancements in Beijing’s naval capabilities, including a breakthrough in submarine tracking technology that exploits a weak spot in U.S. submarines.

Chinese Submarine Advancements
The study details the advanced Chinese submarines that pose a potential threat to U.S. underwater dominance. These submarines are equipped with technological features that enhance their stealth and operational range. The study also provides metrics on the size of China’s submarine fleet and its deployment capabilities, which contribute to the perceived threat.
Recent Chinese naval investments align with the study’s projections for future underwater threats. These investments include the development of advanced submarines and the implementation of innovative submarine tracking technologies. The study suggests that these advancements could potentially undermine U.S. dominance in underwater warfare.
Breakthrough in Submarine Tracking
In 2023, Chinese scientists uncovered a new solution for detecting submarines. This breakthrough exploits a weak spot in U.S. nuclear submarines, known as the “bubble trail.” The bubble trail is a trail of bubbles left behind by a submarine as it moves underwater, which can potentially be used to track its movements.
This method could undermine stealth operations, giving Chinese forces a tactical advantage in underwater scenarios. The potential implications of this discovery were reported in a 2023 article, which can be accessed here.
Implications for U.S. Naval Strategy
The warnings presented in the 2025 study necessitate updates to U.S. submarine detection and countermeasures against Chinese advancements. The discovery of the bubble trail as a vulnerability could force revisions in American submarine design and patrol routes.
Strategic responses could include enhanced alliances or technology investments to preserve U.S. underwater dominance amid these threats. The study suggests that the U.S. must adapt its naval strategy to address the potential risks posed by advanced Chinese submarines and their innovative tracking technologies.
Historical Context of Underwater Rivalry
The U.S. has historically dominated underwater warfare, thanks to its advanced submarine technology and strategic naval operations. However, the 2025 study highlights the rapid advancements in Chinese submarine technology, which could potentially challenge this dominance.
Prior to the 2023 breakthrough in submarine tracking, China had been making steady progress in submarine technology. The study connects these past events to the current warnings, showing how incremental advances have built towards the present threat level.
Expert Perspectives on the Warnings
Naval experts have expressed varying views on the warnings presented in the 2025 study. Some believe that the advancements in Chinese submarine technology and the discovery of the bubble trail tracking solution pose a significant threat to U.S. underwater dominance. Others, however, argue that these developments can be mitigated through innovation and strategic planning.
Specialists in underwater acoustics have also weighed in on the feasibility of the bubble trail tracking solution since its announcement in 2023. While some experts believe that this method could potentially undermine stealth operations, others argue that its effectiveness in real-world scenarios remains to be seen.
