The Armed Forces of the Philippines, the Japan Maritime Self Defense Force and the United States Navy, demonstrating a collective commitment to strengthen regional and international cooperation in support of a free and open Indo-Pacific, conducted a multilateral Maritime Cooperative Activity (MCA) within the Philippines’ Exclusive Economic Zone, March 28, 2025.
This iteration builds upon previous MCAs and our continuing operations together, which strengthens the interoperability of our defense/armed forces doctrines, tactics, techniques, and procedures.
MCAs are conducted in a manner that is consistent with international law and with due regard to the safety and navigational rights and freedoms of all nations. Participating units included the U.S. Navy Arleigh Burke-class guided-missile destroyer USS Shoup (DDG 85) and a P-8A Poseidon maritime patrol and reconnaissance aircraft, the Philippine Navy Jose Rizal-class guided-missile frigate BRP Jose Rizal (FF 150) and King Air C-90 aircraft, and the Japan Maritime Self Defense Force Mogami-class frigate JS NOSHIRO (FFM 3).
The U.S., along with our allies and partners, upholds the right to freedom of navigation and overflight and other internationally lawful uses of the sea related to those freedoms.
