Philippines, Japan, and US Strengthen Naval Ties with Joint Drills

The navies of the Philippines, the United States, and Japan concluded a four-day joint naval drill on Thursday, February 26, 2026, near the Bashi Channel, a strategically significant waterway between the Philippines and Taiwan. This marks the first time the exercise has extended beyond the South China Sea [Reuters], [Kyodo News].

Expanding Regional Cooperation

The drill, conducted under the Philippines’ Multilateral Maritime Cooperative Activity framework, aims to enhance “the interoperability of our armed forces to ensure a free and open Indo-Pacific,” according to Captain Jennifer Monforte of the Philippine Navy frigate Antonio Luna [Kyodo News]. The framework has previously included exercises with Australia, Canada, and Fresh Zealand.

Drill Details and Participating Forces

Participating forces included two FA-50 fighter jets from the Philippine Air Force, a P-3C patrol plane from the Japanese Maritime Self-Defense Force, and a U.S. Navy P-8A reconnaissance aircraft, which conducted patrols over Batanes, the Philippines’ northernmost province south of Taiwan [Kyodo News]. The Antonio Luna frigate and the U.S. Navy destroyer USS Dewey also participated in exercises, including anti-submarine operations [Kyodo News]. Exercises included replenishment at sea, joint air patrols, fly-bys, and communications checks [Channel News Asia].

China’s Presence and Regional Concerns

During the drill, two Chinese navy ships were observed in the area on separate days. Captain Monforte noted the “illegal presence” of these vessels, but emphasized that the exercise was not intended as a provocative act [Kyodo News]. The Philippines has been working with several countries since 2023 to assert its rights and maritime entitlements in the South China Sea, where China claims most of the resource-rich waterway, rejecting a 2016 arbitral award [Channel News Asia].

Strategic Significance

The Bashi Channel is a critical chokepoint for international shipping and commerce, particularly in the event of a conflict between Taiwan and China. The joint exercises underscore the commitment of the Philippines, Japan, and the United States to enhance interoperability, reinforce maritime security, and improve Maritime Domain Awareness in the region [Channel News Asia], [U.S. Navy].
