The Armed Forces of the Philippines (AFP), together with the United States Pacific Command (USPACOM) and the Australian Defence Force (ADF), successfully concluded the 19th Multilateral Maritime Cooperative Activity (MMCA) in the West Philippine Sea from August 19 to 25, 2026.
A one-week activity successfully enhanced maritime interoperability and operational coordination among the participating forces through a series of complex maritime and air operations designed to strengthen their capability to operate seamlessly together in support for a free, open, and secure Indo-Pacific.
The Philippines deployed the BRP Diego Silang (FFG7), a Philippine Navy AW109 helicopter, Philippine Air Force FA-50 fighter aircrafts, C-208B aircraft, and Sokol Search and Rescue (SAR) helicopter. The Philippine Coast Guard likewise participated through the deployment of BRP Teresa Magbanua (MRRV-9701). The United States participated with the USS Santa Barbara (LCS-32) and P-8A Poseidon aircraft, while Australia deployed HMAS Supply (A-195), along with MH-60R helicopter and P-8A aircraft.
Throughout the activity, participating forces successfully conducted advanced maritime interoperability exercises, including Communications Exercises (COMMEX), Maritime Domain Awareness (MDA), Anti-Submarine Warfare (ASW), Replenishment at Sea (RAS), Division Tactics (DIVTACS) / Officer of the Watch (OOW) Maneuvers, Photo Exercise (PHOTOEX) and fly-by operations.
The successful completion of the 19th MMCA underscores the enduring commitment of the Philippines, the United States, and Australia to strengthening defense cooperation, enhancing interoperability, and promoting peace, stability, and security in the Indo-Pacific region.
