US Carrier Enters Scarborough Waters Amid Tensions

On July 22nd, the USS George Washington, a US supercarrier, entered the Luzon Strait, carrying an air wing and approximately 5,000 sailors.

This deployment was a direct reaction to recent aggressive incidents involving China Coast Guard vessels and Philippine ships at Second Thomas Shoal and Scarborough Shoal, aiming to address escalating regional tensions.

In a series of confrontations, Chinese personnel used wooden batons and oars against Philippine craft, injuring two Philippine service members who required evacuation for treatment.

Additionally, water cannons were fired at Philippine vessels near Scarborough Shoal, with Manila reporting the presence of 12 China Coast Guard vessels and three maritime militia ships during these incidents.

Following the incidents, Philippine and Chinese officials presented conflicting accounts, with Commodore J. Tarriela condemning the 'dangerous and unprofessional' actions of the China Coast Guard, asserting Scarborough Shoal is a traditional Filipino fishing ground where foreign powers cannot lawfully block their rights.

In contrast, Beijing claimed its forces had 'tracked and driven away' Philippine vessels, accusing Manila of infringement and describing its own conduct as professional and lawful.

US officials reiterated strong support for the Philippines, with Secretary of State Marco Rubio reaffirming commitment to treaty partners and Ambassador Lee Lipton stating the carrier strike group's presence was to uphold freedom of navigation.

Conversely, Chinese Foreign Minister Wang Yi warned Manila of 'bitter consequences' for provoking Beijing, signaling a rise in diplomatic tensions between the two major powers.

Scarborough Shoal, located 124 nautical miles off the coast of Luzon, has been a major flashpoint due to its history of illegal occupation and disputed legal status.

Beijing has maintained effective control of the shoal since a 2012 standoff, despite a 2016 arbitral tribunal in The Hague rejecting China's 'sweeping historic rights claim' over the area.

Ship tracking data analysis reveals a significant and consistent increase in China's maritime presence at Scarborough Shoal, with China Coast Guard patrols reaching 993 ship days in early 2026, up from 90 ship days in 2025 to 156 in 2026.

Beijing employs floating barriers and research structures to enforce what is described as a 'slow, patient occupation' of the water, a tactic that conventional military assets like a carrier cannot effectively counter.

Supercarriers and their strike groups are primarily designed for high-end warfare, focused on tracking ships and aircraft in a direct military conflict, making them ill-suited for the 'grey-zone' tactics employed by China.

China's actions, such as using water cannons and harassing fishing vessels, are deliberately calibrated to remain below the threshold where military force becomes an 'obvious answer,' rendering conventional military intervention ineffective for these situations.

Deploying a supercarrier into such a standoff does not resolve the issue but risks handing Beijing a propaganda gift and increasing the odds of an accidental escalation into a crisis.

The fundamental issue is that carriers are not designed to address the nuanced, sub-threshold pressures characteristic of 'grey-zone' conflicts.

From July 24-28, the USS George Washington operated southwest of Luzon, engaging in joint exercises with Philippine frigates and Japanese destroyers.

Further reinforcing multilateral presence, the HMAS Perth from Australia also participated in exercises in August, demonstrating allied cooperation in the region.

In response to the US carrier presence, China's PLA Southern Theater Command conducted joint naval and air patrols, notably including H6K bombers equipped with anti-ship missiles.

These maneuvers served as a demonstration of Beijing's capacity to reach the same contested waters faster and maintain a presence longer than the American forces, underscoring its logistical advantage.

The USS George Washington made a diplomatic port call in Vietnam, marking the first visit by a US carrier to the country since 2023.

This visit underscores Vietnam's strategy to seek American regional influence without committing to formal alliances, balancing its relationships amidst regional power dynamics.

On August 19, the USS George Washington transited the Strait of Malacca, redeploying to the Arabian Sea to support Operation Epic Fury, which required a fresh flight deck.

This departure left a significant gap, as the George Washington is the US Navy's only forward-deployed carrier homeported at Yokosuka, Japan.

Consequently, there is currently no American carrier strike group positioned west of San Diego, raising concerns about the US presence in the Indo-Pacific.

Nations like Vietnam, Malaysia, Indonesia, and Brunei seek to maintain a delicate balance rather than aligning with hard blocs, making full reliance on trade with China difficult.

The fleeting nature of carrier visits, with a carrier arriving during a crisis and leaving before its resolution, does not resolve regional security calculations; instead, it sharpens the argument for hedging, which complicates regional stability.

President Ferdinand Marcos Jr. has firmly stated that Filipinos will not yield on the 2016 ruling regarding Scarborough Shoal, vowing to defend it.

Manila is now focusing on practical measures, such as providing fishermen with essential supplies and fuel at sea, and advocating for a binding code of conduct within ASEAN to manage regional disputes.

The partnership between the US and the Philippines remains central to preserving stability in the South China Sea, according to President Ferdinand Marcos Jr.

Beyond individual carrier deployments, the US has pledged over $100 million for infrastructure, including initiatives like the Luzon economic corridor and joint patrols, as long-term stabilizers for the region.

The control of areas like Scarborough Shoal is determined daily by which Coast Guard has more vessels on station and whose fishermen can still operate within the lagoon.

This highlights that actual maritime control in contested waters is maintained through sustained presence and local activities, rather than the fleeting deployment of large warships, emphasizing the danger of an unrecoverable mistake in the region.
