China's Shipbuilding Surge Widens Naval Lead as U.S. Struggles to Rebuild

A bigger Chinese fleet changes the balance at sea

China operates more than 370 naval ships, accounts for more than 60% of global ship orders and has built an industrial base that is expanding its fleet faster than the United States can match. As of September 1, 2025, that combination is changing the military balance across the Indo-Pacific and increasing pressure on Washington to rebuild its shipyards.

The People's Liberation Army Navy, known as the PLAN, is projected to reach 435 ships by 2030. The U.S. Navy has roughly 290 ships and a goal of 381 in the coming decades. China already has the world's largest navy by number of warships, although the United States retains advantages in total fleet tonnage, large aircraft carriers and submarines powered by nuclear reactors.

China's expansion joins two kinds of power: an industry that builds commercial ships for customers around the world and a navy increasingly capable of operating beyond Chinese waters. State direction, investment in shipyards and the integration of civilian and military production have helped turn an outdated force of the 1990s into a much larger and more modern fleet.

The consequences reach from disputed waters in the South China Sea to shipping routes connecting China with the Persian Gulf and Africa. For the United States and its partners, the challenge involves building ships, maintaining those already deployed and keeping access to ports and repair facilities close to potential areas of conflict.

How China's shipyards gained their advantage

China has around 175 major shipyards, many capable of building both commercial and military vessels. The United States has seven major shipyards. China has led commercial shipbuilding since 2018, and its yards are estimated to be 200 times more productive than those in the United States.

China's four largest shipyards produced 39 warships in 2024, with a combined displacement of 550,000 tonnes, more than the entire Royal Navy of the United Kingdom. Displacement describes a ship's weight through the amount of water it pushes aside, giving a measure of vessel size alongside a simple count of hulls.

The 2019 merger of China's two largest state owned shipbuilding companies into the China Shipbuilding Group Corporation brought production and technology transfer into a more integrated structure. That helped support the rapid expansion of naval construction. About 70% of Chinese warships were launched after 2010.

China's commercial orders support an industrial network of facilities, workers and suppliers that also serves military construction. The United States now controls less than 0.1% of global shipbuilding capacity, a sharp decline from its dominance after World War II.

Commercial production supports military expansion

China's policy of military-civilian fusion connects commercial industry with military needs. In shipbuilding, facilities that produce cargo ships can also build warships or support vessels, allowing production to shift as priorities change.

Shipyards serving both markets can share skills, equipment and production capacity. Commercial orders help sustain the scale of the industry, while military construction benefits from that broader industrial base. The flexibility could give China an advantage during a prolonged conflict by helping it replace lost vessels and sustain naval operations faster than its rivals.

Foreign companies also place orders at Chinese yards that undertake military work. Those contracts can indirectly support naval modernization through technology transfer and economies of scale, meaning the savings and efficiencies that come from producing large quantities.

The resulting system links China's position as a commercial shipbuilder with its ambitions at sea. Its advantage lies in the industrial capacity behind the fleet as well as in the ships already in service.

What the fleet numbers reveal

China has doubled its destroyer fleet over the past two decades and is on track to exceed the United States in the number of vertical launch missile cells by 2027. These cells are compartments from which ships launch missiles. More cells allow a fleet to carry and deploy more missiles at sea.

The projected rise from more than 370 ships to 435 by 2030 represents continued expansion from an already larger fleet. Washington's goal of 381 ships is higher than its current roughly 290, but reaching that target depends on overcoming production and maintenance problems.

The United States retains an advantage in total tonnage and operates more large aircraft carriers. It also has 66 submarines powered by nuclear reactors, compared with China's 12. Such submarines use reactors for propulsion and form an important part of the American naval advantage.

Chinese submarine technology and carrier aviation remain less advanced, although investment in vessels such as the Type 003 aircraft carrier and in unmanned underwater drones is narrowing the gap. Training, personnel quality and coordination also shape how effectively either country can use its ships.

The main stages of China's expansion and the next projected milestones span several years:

• In the 1990s, China's navy was largely outdated.
• In 2017, China established its military installation at Djibouti's Doraleh port.
• Since 2018, China has led global commercial shipbuilding.
• In 2019, its two largest state owned shipbuilding companies merged.
• By 2021, the PLAN had surpassed the U.S. Navy in battle force ship numbers.
• In 2024, China's four largest shipyards produced 39 warships.
• By 2027, China is projected to surpass the United States in vertical launch missile cells.
• By 2030, the Chinese fleet is projected to reach 435 ships.

Why Beijing wants a stronger navy

China depends on secure sea routes for 95% of its international trade. Seven of the world's ten busiest ports are in China, tying its economic interests closely to maritime transport. Protecting routes to energy suppliers and trading partners is a central reason for its naval expansion.

Beijing also seeks to assert its territorial claims in the South and East China Seas, discourage U.S. intervention in regional disputes and protect commercial interests along routes reaching the Persian Gulf and Africa. A larger navy gives China more vessels to maintain a presence in those waters and farther away.

Taiwan is another central consideration. Beijing regards Taiwan as a breakaway province, and the PLAN's modernization is intended in part to support potential military operations against it. U.S. intervention in a regional conflict is among the possibilities Chinese planning seeks to deter.

President Xi Jinping has repeatedly stressed the need for a strong navy to prevent a repeat of foreign invasions and concessions during the colonial era. Naval expansion is presented as both protection against earlier humiliations and a restoration of national standing.

Chinese officials describe the buildup as defensive and focused on protecting maritime interests. They have stated that China has no interest in military interference abroad, except for Taiwan. Growing Chinese naval activity around Australia and near Japan has nevertheless increased regional concern and demands for greater transparency and measures to build confidence.

Ports extend China's reach beyond its shores

China's Belt and Road Initiative and Maritime Silk Road have supported investment in overseas ports and infrastructure across Asia, Africa and Europe. By 2023, China had signed 70 bilateral and regional shipping agreements with 66 countries, helping establish shipping routes and service networks around the world.

Djibouti's Doraleh port hosts China's most significant overseas military installation. Established in 2017, it supports missions against piracy and provides logistical assistance to Chinese naval vessels. Logistics includes the supplies and services ships need to continue operating away from home.

Cambodia's Ream Naval Base has hosted Chinese warships and is viewed as an important location for projecting power in Southeast Asia. It has officially been described as a commercial facility. U.S. intelligence agencies have identified Pakistan, Sri Lanka, Equatorial Guinea and the United Arab Emirates as other places where China may seek military facilities.

The United States maintains more than 128 overseas military bases. China's approach relies more heavily on commercial port investments that can also have military uses. Access to such facilities can offer flexibility and support naval deployments while avoiding some of the political difficulties of formal agreements for military bases.

Host countries also face financial and diplomatic pressures. Many countries hosting Chinese port investments are heavily indebted to China and face economic instability. The combination of borrowing, infrastructure investment and potential military access has prompted concerns about debt sustainability and Beijing's influence over their decisions.

Washington tries to rebuild its maritime industry

The Trump administration has issued an executive order to restore American maritime dominance, directing federal agencies to develop a Maritime Action Plan. It has also proposed new fees on ships manufactured in China when they enter U.S. ports.

Congress has passed legislation allocating tens of billions of dollars to the shipbuilding and repair industrial base. The measures include investment in workforce training and shipyard modernization, aimed at expanding the industry's ability to construct vessels and maintain those already serving.

U.S. shipbuilders face production shortfalls, labor shortages and limits at existing facilities. Delays raise costs and reduce operational readiness because ships may arrive late or spend longer awaiting work. Building advanced warships, including the Arleigh Burke-class destroyer, takes years longer in the United States than in China.

The American shipbuilding workforce has fallen from 120,000 to about 72,000 over two decades. That is a loss of roughly 48,000 workers, or 40% of the earlier workforce. Restoring output requires people with the skills to perform complex construction and repair work alongside investment in facilities.

The U.S. merchant fleet has also contracted to fewer than 180 ships engaged in international trade. This limits sealift capacity, the ability to move supplies and equipment by sea, in a contested environment. The loss of expertise and industrial capacity has prompted calls for a modern Marshall Plan to rebuild American maritime power.

Allied shipyards and regional access gain importance

Washington is deepening maritime partnerships with Japan, South Korea, India and the Philippines. American warships are now undergoing overhauls in Japanese and South Korean commercial yards as the United States expands access to maintenance and repair facilities across the Indo-Pacific.

Regional repair capacity helps sustain an American presence near the waters where China is increasingly active. These partnerships are intended to support readiness while domestic shipbuilders work through their own capacity constraints.

Japan has designated 14 airports and 26 seaports for military use during a contingency. The measures reinforce the First Island Chain, a line stretching from Japan through Taiwan and the Philippines that features prominently in efforts to restrict Chinese military activity in the Western Pacific.

Japan has also strengthened missile defenses and expanded access by its Self-Defense Forces to civilian infrastructure. Those decisions reflect concern about China's ballistic missiles and naval operations near the Ryukyu Islands and Taiwan.

The AUKUS pact and the Quad initiative form part of the wider security response. The Quad brings together the United States, Australia, Japan and India. These arrangements aim to strengthen maritime security cooperation and deter Chinese aggression, alongside the region's network of alliances and partnerships.

More ships bring operational risks

An August 2025 collision between a PLAN destroyer and a China Coast Guard vessel near Scarborough Shoal exposed coordination problems between two arms of China's maritime forces. The incident highlighted both the assertiveness of Chinese operations in disputed waters and the difficulties of managing different forces together.

China's navy and coast guard have different functions, making coordination important when their vessels operate close to one another. The collision brought command and control problems into focus as China expands the number and reach of its ships.

A larger fleet strengthens Beijing's ability to enforce maritime claims, project military power and challenge the United States in waterways including the South China Sea and Taiwan Strait. The practical effect is more capacity to sustain a presence in disputed areas and support operations farther from Chinese shores.

China's ability to repair and replace ships quickly could become valuable in a prolonged conflict. Effective operations still depend on trained crews, capable leadership and cooperation between organizations. Industrial production supplies the vessels; personnel and command systems determine how those vessels work together at sea.

Regional governments weigh security and trade

Japan, Australia and India have increased defense spending, expanded maritime patrols and strengthened security cooperation with the United States. Southeast Asian countries face a more delicate balance between economic ties with China and concern about its actions in the South China Sea.

American and allied efforts also seek to expand shipbuilding capacity outside China. Recommendations include investing in allied yards, imposing docking fees on vessels made in China and cutting financial ties with Chinese state owned shipbuilders. U.S. labor unions and industry groups have called for stronger domestic support and tougher penalties against Chinese dominance.

For countries that depend on maritime trade, this competition connects security decisions with commercial interests. Chinese yards hold more than 60% of global ship orders, while China's navy and overseas port network extend its influence along routes used by other trading nations.

The United States faces the task of rebuilding industrial capacity while sustaining its forward presence. Without stronger investment and action, it risks losing influence linked to its ability to operate across the world's oceans. China, meanwhile, continues to expand a fleet backed by a much larger commercial shipbuilding industry.

The balance at sea now turns on several connected capabilities: how many ships each country can build, how quickly it can repair them, where they can receive support and how well their crews can operate them. China's advantage in construction has widened, while American advantages in major platforms and its network of partners remain central to the competition.
