China’s newest and most capable aircraft carrier is now moving through some of the most politically charged waters on the map.

The CNS Fujian, Beijing’s third carrier and its most advanced by far, was spotted transiting the Taiwan Strait on Tuesday, according to reporting from Newsweek. Taiwan’s Defense Ministry later confirmed the carrier’s presence in the Taiwan Strait—a waterway roughly 80 miles wide at its narrowest point—and said the island’s military monitored and responded to the passage.

The Chinese Foreign Ministry did not immediately respond to requests for comment, but the transit itself sends a clear enough message.

Why the Fujian’s transit matters

On one level, carrier movements are routine: navies sail their capital ships to signal presence, train crews, and test systems. On another level, the Fujian’s appearance in the Taiwan Strait fits neatly into Beijing’s broader campaign of sustained military pressure on self-ruled Taiwan.

China has long claimed the island as its own territory and has repeatedly threatened to take Taiwan by force for “reunification” if political coercion fails. To keep that threat credible, the People’s Liberation Army maintains a strong air and naval presence around Taiwan, with near-daily incursions across the median line of the strait and regular encirclement drills.

Beijing also insists that it holds sovereignty, sovereign rights, and jurisdiction over the entire Taiwan Strait. In contrast, the United States treats the waters beyond the 13.8-mile territorial seas off China and Taiwan as international waters, and U.S. officials regularly challenge Beijing’s position in public statements and through naval transits.

Against that backdrop, sending the Fujian—China’s most advanced flattop—through the strait is less about moving a ship from point A to point B and more about signaling capability and intent.

A carrier built to project power

Among the more than 370 warships in China’s navy, three are aircraft carriers. The Fujian, commissioned in November, stands out as the most capable of the trio.

Unlike China’s first two carriers, which rely on ski-jump decks, the Fujian is equipped with electromagnetic catapults. That puts it in a relatively exclusive club alongside the U.S. Navy’s newest Ford-class carriers. The catapults allow the ship to launch heavier, more capable aircraft, including fixed-wing early-warning platforms and fully fueled strike fighters, expanding both the range and weight of what the carrier air wing can bring to a fight.

A black-and-white photograph released by Taiwan’s Defense Ministry appears to show the Fujian with no visible aircraft on its flight deck as it crossed the strait. That detail suggests this was more of a transit and systems run than a full-up carrier strike group exercise, but even a relatively “clean” deck does not dilute the symbolism of China’s newest carrier moving through contested waters.

Tracking the carrier’s route

The Fujian was captured on video leaving its home port at Yulin Naval Base on the northern edge of the South China Sea on Sunday. Its northbound transit through the Taiwan Strait implies a trajectory toward the East China Sea, but its precise destination remains uncertain.

Analysts have floated two main possibilities:

• A return to Shanghai’s Jiangnan Shipyard, where the Fujian was built between 2017 and 2022, likely for additional workups or maintenance.
• A move to Yuchi Naval Base on China’s northeastern coast, which currently hosts the country’s first carrier, CNS Liaoning.

Open-source imagery is helping narrow down the picture. University of Tokyo professor and OSINT analyst Hidenori Watanave shared a satellite image of Yulin Naval Base showing only CNS Shandong still pier-side. Separate satellite imagery of Yuchi Naval Base captured Tuesday indicates the Liaoning has returned from a deployment near Japan’s southwestern outlying islands.

In other words, all three of China’s carriers—Liaoning, Shandong, and Fujian—are in motion or recently active in ways that underscore how quickly Beijing’s carrier force is maturing.

The air picture over and around Taiwan

The Fujian’s transit did not occur in isolation. Following its passage, Taiwan’s military detected 14 Chinese combat aircraft, including an unspecified number of H-6K bombers, operating around the island outside its official airspace after crossing the median line of the Taiwan Strait.

This pattern—high-profile naval movements paired with elevated air activity—has become a hallmark of China’s pressure campaign. It keeps Taiwan’s forces on constant alert, normalizes PLA operations around the island, and complicates crisis management for both Taipei and Washington.

How Beijing is framing the seas

China’s messaging about the legal status of the Taiwan Strait is as assertive as its military posture. In June 2022, the Chinese Foreign Ministry declared that there is “no legal basis of ‘international waters’ in the international law of the sea” and labeled the term a “false claim” used by other countries to “manipulate issues related to Taiwan” and threaten China’s sovereignty and security.

That position runs directly counter to how the United States and many of its allies interpret the UN Convention on the Law of the Sea, and it sets the stage for recurring friction whenever U.S. or allied warships operate in or near the strait.

At the same time, Chinese officials continue to celebrate their growing carrier fleet. Marking the sixth commissioning anniversary of Shandong, the Chinese military boasted that the ship’s “footprints [have extended] farther into the deep blue” and that its “combat capabilities have been greatly honed.” The message is clear: China’s carriers are meant to operate well beyond the immediate neighborhood.

What happens next

The open question is when the Fujian will undertake its first full-fledged operational deployment to waters east of the First Island Chain—the notional line formed by Japan, Taiwan, and the Philippines that underpins U.S. and allied maritime strategy in the Western Pacific.

Sailing through the Taiwan Strait with a mostly empty deck is one thing; surging into blue water with a fully worked-up air wing and integrated escorts is another. For now, the Fujian’s movements look like part of an extended shakedown and signaling campaign.

Still, the trajectory is hard to miss. Each new image and video clip of China’s carriers at sea reinforces the reality that Beijing is not just building symbols—it is methodically assembling a carrier fleet meant to operate in, around, and well beyond some of the most contested waters on Earth.
