The Philippines, the United States, and Japan conducted another round of maritime drills in the West Philippine Sea (WPS), underscoring the deepening security cooperation between the country and its allies.

The 13th Multilateral Maritime Cooperative Activity (MMCA), held Friday and Saturday, brought together major assets from the Armed Forces of the Philippines, US Indo-Pacific Command, and the Japan Maritime Self-Defense Force, according to a news release.

The AFP deployed its two missile-capable frigates, BRP Jose Rizal (FF150) and BRP Antonio Luna (FF151), along with an AW159 helicopter.

The US sent the Nimitz Carrier Strike Group led by the USS Nimitz (CVN 68) while Japan fielded JS Akebono (DD-108) and an SH-60K Seahawk.

The Philippine Coast Guard’s BRP Melchora Aquino and BRP Cape San Agustin also supported the mission, enhancing maritime domain awareness in the WPS.

The AFP said the exercise featured a full suite of interoperability drills: communications checks, resupply-at-sea approaches, antisubmarine exercises, maritime domain awareness reporting, cross-deck helicopter landings, formation maneuvers, and a final integrated exercise.

It added that the sustained MMCA series reflects the AFP’s commitment “to safeguarding the nation’s sovereign rights and advancing collective defense readiness with trusted partners,” especially amid continued Chinese harassment of Philippine vessels.
