A Resurgence in Submarine Power
The world’s submarine fleets are growing at a remarkable pace, reminiscent of the naval build-ups during the 1980s. What sets this modern era apart is the significantly broader participation of nations. Over the last five years, from 2021 to the present, an estimated 77 submarines have been launched by approximately 16 different countries. This impressive figure includes 33 nuclear-powered submarines, with six nations operating these advanced vessels: China, Russia, the United States, the United Kingdom, France, and India. Furthermore, Brazil and North Korea have nuclear-powered submarines currently under construction, though they have yet to be unveiled. Looking ahead, South Korea and Australia have also declared intentions to operate nuclear-powered submarines, indicating a continuing global shift.
China’s Unmatched Output and Innovation
While many countries are expanding their submarine capabilities, China’s rapid progress in both volume and technological sophistication is particularly striking. In the past five years alone, China has launched around 24 submarines, a figure that is double Russia’s output of 12 and more than triple the United States’ production of 7 boats. This impressive rate of construction underscores China’s commitment to bolstering its underwater presence.
Driving Force Behind Innovation
The difference between China and other major powers like Russia and the United States isn’t solely measured in numbers; it’s also in the pace of innovation. China has introduced seven new classes of submarines within this timeframe, showcasing a dynamic approach to naval development. In contrast, Russia’s 12 launches included only one new class, the Khabarovsk, which had been in development for over a decade. The United States, meanwhile, has focused its production on the well-established Virginia Class. While this doesn’t necessarily mean individual Chinese submarines are more advanced, it highlights a significantly faster development cycle.
Pioneering Uncrewed Underwater Technology
A key area where China demonstrates a distinct advantage is in the development of extra-extra-large underwater drones (XXLUUVs). These are not the standard large underwater drones; China is uniquely building uncrewed platforms that rival the size of conventional crewed submarines. This groundbreaking work in autonomous underwater systems represents a significant leap forward. Additionally, China is at the forefront of implementing small nuclear power plants, often referred to as nuclear-Air Independent Power (AIP), a technology observed in their Type-041 Zhou Class submarines.
Global Reach Through Exports
China’s submarine manufacturing prowess extends beyond its own fleet, with four Hangor class submarines built for export to Pakistan as part of a significant deal. While Germany and France are also notable exporters of submarine technology, France did not launch any export vessels during the reviewed period. The general trend over the last three decades has been towards technology transfer and local production capabilities for recipient nations, a pattern exemplified by the China-Pakistan collaboration. This proliferation of submarine building expertise is a significant factor in the growing number of countries operating underwater assets.
China’s Strategic Shift to Nuclear Power
While conventional non-nuclear submarines remain a crucial component of China’s underwater force, the nation is strategically pivoting towards nuclear-powered vessels. Historically, nuclear submarine construction was concentrated at a single shipyard in Huludao. However, two shipyards along the Yangtze River, the Wuchang shipyard in Wuhan and the JN yard in Shanghai, have now joined this effort. Wuchang is anticipated to focus on the Type-041 Zhou class ‘mini-nuke,’ while JN is undertaking the construction of much larger nuclear submarines. The first nuclear-powered boat launched at JN is a new, as-yet-unnamed class of attack submarine, notable for its exceptionally small sail. A sister submarine was launched in Huludao shortly thereafter. The precise details of this new class and its relationship to the also-new Type-095 remain under observation.
Accelerating Nuclear Submarine Production
With three shipyards now engaged in nuclear submarine construction, the focus of China’s shipbuilding efforts is expected to increasingly shift towards nuclear platforms. China is already capable of launching multiple nuclear submarines annually, and a realistic projection suggests this rate could rise to approximately six per year. This output would be triple the rate the United States is aiming to achieve. Concurrently, China’s southern shipyards appear to be concentrating on uncrewed submarine development. Although conventional submarines will remain a significant part of their naval strategy for at least another decade, their emphasis may diminish as nuclear submarines take a more prominent role at the higher end of their capabilities and large uncrewed platforms emerge at the lower end.
Future Outlook for Global Submarine Fleets
The coming years are set to witness the launch of new submarines by an even wider array of countries. While many of these vessels will serve domestic defense needs, a growing number are being designed for export. Spain and South Korea are notable emerging players in this export market. Despite these advancements, China is widely expected to maintain its dominant position in submarine production, even as major new submarine classes begin to be introduced by established naval powers like the United States and the United Kingdom.
Conclusion
The global submarine landscape is undergoing a significant transformation, marked by increased construction rates and a broader international participation. China has emerged as the undisputed leader in this domain, not only in terms of sheer volume but also in its rapid technological development and pioneering work in uncrewed underwater systems. This trend suggests a dynamic future for naval power, with underwater capabilities becoming increasingly crucial for nations worldwide.
