For decades, the United States Navy has been the dominant power on the world’s oceans—a deterrent to aggression, a guarantee of freedom of navigation, and a projection of strength that has underpinned global stability. Yet in recent years, that dominance has begun to erode, not through defeat but through neglect. China’s extraordinary shipbuilding surge has given it the world’s largest navy in sheer numbers, while America’s fleet has dwindled, slowed by budgetary gridlock, political short-termism, and industrial atrophy. The United States must now decide whether it intends to remain a maritime superpower or cede control of the seas to Beijing.
China currently fields more than 370 warships, a figure projected to grow to 440 within a few years. The United States, by comparison, maintains about 290 active vessels. The disparity grows more striking when one considers shipyard capacity. China has transformed its coastline into a vast complex of shipyards that can produce destroyers, frigates, submarines, and amphibious assault ships at a rate the U.S. can no longer match. Where America’s shipyards have consolidated and aged, China’s are multiplying, modernizing, and operating around the clock.
Raw numbers do not tell the full story, of course. The U.S. Navy still possesses the globe’s most powerful fleet of nuclear-powered aircraft carriers and submarines—assets that no other nation can yet duplicate. America has 11 nuclear carriers, each capable of deploying an entire air wing anywhere in the world, while China has only three, with limited range and experience. The United States also maintains 68 nuclear-powered submarines, many of them ballistic-missile or fast-attack boats that remain stealthy and lethal. China, by contrast, has roughly a dozen nuclear-powered submarines, most of them older models and considerably noisier.
Still, trends matter. China’s industrial base allows it to launch new hulls at a pace unseen since World War II, while America’s shipyards struggle with maintenance backlogs and workforce shortages. Building a new submarine can take nearly a decade in the U.S., even longer when key components or trained welders are in short supply. Congress and the Pentagon have too often been content to plan for “future studies” instead of investing in the tools and talent necessary to expand capacity now.
To catch up, the United States will need more than rhetoric. It will require a national maritime mobilization on a scale not seen since the Reagan era. That means expanding the Navy’s shipbuilding budget, incentivizing private-sector yards, recruiting and training a new generation of engineers and skilled tradesmen, and streamlining procurement so that new ships can be authorized and laid down without years of red tape. It also means thinking creatively—repurposing commercial shipyards, integrating modular design, and employing artificial intelligence to improve logistics and maintenance cycles.
Equally important is strategic clarity. The U.S. cannot afford to build ships simply to meet a quota. It must build the right fleet for the challenges of the coming decades—flexible, distributed, and networked. That means more submarines to patrol the Pacific’s contested depths, more frigates and destroyers capable of missile defense, and perhaps most crucially, more unmanned surface and undersea vessels that can extend the Navy’s reach without putting sailors at risk.
The oceans remain the lifeblood of global commerce and the first line of defense for a nation separated from its adversaries by vast distances. If America allows its naval strength to wane, it will not just lose influence—it will lose security. History shows that when free nations retreat from the sea, authoritarian powers fill the void. The Chinese Communist Party understands this, which is why it has turned shipbuilding into a strategic weapon. The United States must respond in kind—not out of nostalgia, but out of necessity.
Rebuilding the fleet will be neither cheap nor quick. But the alternative—a slow surrender of maritime supremacy—is far more costly. The oceans have long been America’s shield and conduit to the world. It is time to renew that inheritance before it slips beneath the waves.
