CLARK FREEPORT ZONE, Philippines — U.S. and Philippine air forces on Monday launched the latest iteration of Cope Thunder, a joint military exercise that returns to Clark Air Base more than three decades after American forces left the site. The two-week drill, running from April 7 to 18, brings together hundreds of troops and a fleet of aircraft for intensive aerial training in Northern Luzon.
The opening ceremony, held at Clark Freeport Zone in Mabalacat City, was led by Philippine Air Force Commanding General Lt. Gen. Arthur M. Cordura and U.S. Pacific Air Forces Maj. Gen. Christopher J. Sheppard. The exercise, formally named Cope Thunder Philippines 2025 (CT PH 25-1), aims to boost combat readiness and strengthen interoperability between the longtime allies.
The Philippine Air Force deployed 729 personnel along with FA-50PH fighter jets, A-29B Super Tucano light attack aircraft, and Black Hawk helicopters. The U.S. Pacific Air Forces contributed 250 personnel and 12 F-16 fighter jets. Training will focus on tactical air maneuvers, integrated mission planning, and simulated combat scenarios designed to enhance coordination in real-world operations.
Beyond bilateral training, the Philippines is also hosting an International Observer Program with representatives from the air forces of Australia, Japan, Malaysia, Thailand, and Indonesia. Subject-matter expert exchanges will be held alongside the exercise, covering a broad range of topics in modern air warfare and regional security cooperation.
Clark was once home to the U.S. 13th Air Force and a hub of American military presence in Southeast Asia. After the 1991 eruption of Mount Pinatubo and the Philippine Senate’s rejection of a new basing agreement, the United States withdrew from the facility. The return of Cope Thunder to its former base signals a renewed commitment to defense ties amid rising tensions in the Indo-Pacific region.
