As US Pacific allies eye nuclear submarines, should China be concerned?
US Pacific Allies Aim to Build Nuclear Submarines
Australia, South Korea, and Japan have expressed intentions to develop nuclear-powered submarines (SSNs), a move that analysts say could challenge Beijing’s naval influence in the region.
Challenges in Developing SSNs
According to experts, these countries face significant obstacles in constructing nuclear submarines, a process that may take several decades to complete. Despite these challenges, the effort could complicate China's calculations regarding naval deterrence, especially in a potential conflict around the Taiwan Strait.
Advantages of Nuclear-Powered Submarines
Nuclear submarines, or SSNs, are powered by nuclear reactors but do not necessarily carry nuclear weapons. Compared to conventional diesel-electric submarines, which need frequent refueling, SSNs can operate underwater at higher speeds for prolonged periods, effectively granting them unlimited range.
- Enhanced stealth capabilities
- Greater speed and endurance
- Key strategic assets for maritime deterrence in open seas
Often, these submarines are equipped with submarine-launched ballistic missiles.
China’s Naval Investments
President Xi Jinping demonstrated support for the expansion of China's nuclear submarine fleet by inspecting vessels during two separate occasions: with the South Sea Fleet in 2013 and the North Sea Fleet in 2018.
Author’s Summary
The drive by US Pacific allies to acquire nuclear submarines signals a strategic shift that may increase regional naval tensions and complicate China's maritime deterrence strategies.
