China Now Leads World Submarine Construction​

Published on 24/06/2026


[Click to enlarge] China leads submarine construction with 24 boats in the past 5 years. This includes an estimated 12 nuclear boats. If the survey were extended to smaller ‘extra-large’ uncrewed underwater vehicles (XLUUVs), China’s lead would grow.

More countries are building and operating submarines today than at any point in modern history. Yet amid this global expansion, China has emerged as the dominant force, launching twice as many submarines as any other nation and introducing more new classes.

World submarine construction is growing to levels unseen since the Cold War in the 1980s. And in stark contrast to back then, today many more countries are involved. An estimated 77 submarines have been launched in the past 5 years (2021-present) by some 16 countries. This number includes 33 nuclear-powered submarines in 6 countries (China, Russia, United States, United Kingdom, France and India). Brazil and North Korea also have nuclear-powered boats under construction, but they have yet hit the water. Meanwhile South Korea and Australia have plans to operate nuclear boats.

But one country stands out for both their dramatic increase in volume and rapid pace of technical development. China has established a commanding lead in submarine production. Over the past five years, it has launched about 24 submarines. This is twice Russia’s 12 and more than triple the United States’ output of 7 boats.

Innovation​

The contrast between China and Russia and the United States is in more than just numbers, it’s the rate of improvement. China’s construction includes 7 new classes of boat. Meanwhile, of the 12 boats launched in Russia, only one was of a new class, the Khabarovsk which had been in construction over 11 years. And for the United States, they were all the well-established Virginia Class. This is not to say that Chinese submarines are, on an individual level, more sophisticated but they are developing faster.

One key area where China has a clear edge is the construction of extra-extra-large underwater drones (XXLUUVs). We haven’t counted the regular XLUUVs (with one ‘X’), but China is the only country building underwater drones which are the size of regular crewed submarines and these are included. China is also the first country to going for small nuclear power plants, termed nuclear-AIP (air independent power) which is seen on the Type-041 Zhou Class.


China’s submarine construction includes four Hangor class boats for export, part of a deal with Pakistan. Other countries building significant numbers of submarine for export are Germany and France, although the latter did not launch any export boats during the period. However, the general trend over the past 30 years has been technology transfers with local production and even the Chinese-Pakistan deal is shared production. This trend is driving the proliferation of countries building submarines.

China Goes Nuclear​

Conventional non-nuclear submarines remain a key pillar of China’s submarine force, but the focus is changing to nuclear boats. Until very recently the sole shipyard building nuclear submarines was at Huludao in the north of the country. Now two shipyards on the Yangtze River, the Wuchang shipyard in Wuhan and the JN yard in Shanghai, have joined. Wuchang appears likely to focus on the Type-041 Zhou class ‘mini-nuke’ while JN has begun construction of much larger boats. The first nuclear powered boat launched at JN was a new class of attack submarine, known for its very small fin (sail), which is as-yet unnamed. An identical submarine was launched in Huludao just days apart. Exact details of the new class, and how it relates to the also new Type-095 have yet to emerge.

Given the three yards now building nuclear submarines, the focus of construction is expected to shift to nuclear boats. China can already launch several each year, which a reasonable estimate now increasing to around six per year. This is triple the rate the United States is aiming for.

At the same time, China’s yards in the south of the country seem focused on uncrewed submarines. Although conventional submarines will remain a major force component for at least a decade, they are likely to become smaller and less emphasised part, displaced by more nukes at the top end and large uncrewed platforms at the lower end of their remit.

Outlook​

More countries will be launching new submarines in the coming years. Many will be for local use but increasingly countries are also looking to export their designs, with Spain and South Korea being notable new entrants on the market. However China is likely to continue to dominate, even as major new classes start being launched in the United States and United Kingdom.

From the beginning of 2022 to now, a total of 12 Type 093B attack nuclear submarines have been built and commissioned (the number of Type 094s is unknown) 8 Type 039C conventional submarines have been commissioned plus type 09X and type 095 have been spotted at Jiangnan and Bohai shipyards.

12 nuclear submarines built and commissioned in just 4 years?

12 nuclear submarines built and commissioned in just 4 years?

This was from 2022-2025, and China has probably launched 5 nuclear submarines in the first 5 months of 2026.

This is just the beginning of a massive build up of both surface and subsurface fleets.

China made more submarines than US, Russia combined to dominate global rush​

With seven new submarine classes and expanding nuclear shipyards, China is accelerating underwater fleet development faster than any other nation.

The global submarine industry is busier now than at any time since the Cold War. In the last five years, 16 countries have launched about 77 submarines, showing a big increase in undersea military spending. China stands out as the leader, building more submarines than any other country and quickly rolling out new designs.

China’s rapid submarine expansion sets it apart from traditional naval powers like the United States and Russia. Recent estimates show China has launched about 24 submarines since 2021, twice as many as Russia (12) and more than three times the U.S. total of seven.

Global submarine building reaches Cold War-era levels​

Submarine building around the world is now at levels last seen in the 1980s. Unlike during the Cold War, production is spread across more countries rather than concentrated in a few major powers.

Out of the 77 submarines launched since 2021, 33 are nuclear-powered and were built by six countries: China, Russia, the United States, the United Kingdom, France, and India. Other countries are starting nuclear submarine programs, too. Brazil and North Korea are building nuclear submarines now, and South Korea and Australia plan to have their own nuclear-powered fleets in the future.

More countries are building submarines as part of a bigger change in naval strategy. Submarines are now seen as key for deterrence, intelligence, and maritime security. Because of this, building submarines is no longer limited to traditional naval powers and is spreading to new defense markets.

China’s development pace outstrips competitors​

China’s lead is not just about how many submarines it builds. It is also introducing new submarine designs much faster than other countries.

In the past five years, China has added seven new submarine classes to its fleet. In contrast, Russia launched just one new class, the Khabarovsk, which took over 11 years to build. The United States has only built more submarines from its existing Virginia-class program.

This does not mean each Chinese submarine is more advanced than those from other navies. Still, China’s rapid development and launch of new ideas show how quickly the submarine industry is changing.

China is also ahead in developing very large uncrewed underwater vehicles, called XXLUUVs. These are about the same size as regular crewed submarines. No other country is known to be building underwater drones this big.

Another important step is China’s work on nuclear-powered air-independent propulsion technology. The Type-041 Zhou-class submarine uses what is described as a small nuclear power plant, sometimes called nuclear-AIP.

Expansion of nuclear submarine production​

China’s submarine strategy is increasingly centered on nuclear-powered vessels.

For years, the Huludao shipyard in northern China was the only place in the country building nuclear submarines. Now, two more shipyards along the Yangtze River—Wuchang in Wuhan and the JN yard in Shanghai—are also building them.

Wuchang is expected to build the Type-041 Zhou class, while the Shanghai yard has already launched a larger nuclear-powered attack submarine from a new class. Huludao launched an identical submarine just days later. There is still little information about the design, and it is not yet clear how it relates to the new Type-095 program.

With three shipyards now building nuclear submarines, China’s production capacity is set to grow a lot. Some estimates say China could soon launch about six nuclear submarines each year, which is about three times the U.S. target.

New export markets reshape the industry​

China’s submarine industry is also building submarines for export. Recently, it built four Hangor-class submarines for Pakistan as part of a shared production deal.

Germany and France remain major submarine exporters, while Spain and South Korea are emerging as new players in the global market. More countries are also signing technology-transfer and local-manufacturing deals to help them build their own submarines.

In the future, the United States and the United Kingdom are expected to add new submarine classes. Still, current trends indicate that China will likely remain the main player in global submarine construction.
