Philippines, US, and Japan Conduct Balikatan 2026 Exercises

Military forces from the Philippines, the United States, and Japan have conducted a series of advanced counter-drone and air defense operations as part of the 2026 Balikatan exercises. The drills, which include joint Integrated Air and Missile Defense (IAMD) exercises, focused on detecting, tracking, and neutralizing hostile unmanned aerial systems (UAS) to prevent surveillance and attacks within operational areas.

The exercises took place in several locations, including San Antonio, Zambales, where Philippine and U.S. Forces carried out live-fire training specifically designed to bring down drones. These operations are part of the 41st iteration of Exercise Balikatan, a 19-day series of drills that began on April 20, 2026.

Multinational Integration and Capabilities

This year’s exercises saw a significant increase in multinational participation, with approximately 1,400 Japanese forces joining thousands of American and Philippine troops. The expanded scope of the drills reflects deepening security cooperation among the three nations.

Technical components of the drills included the deployment of specialized air defense systems. Reporting from the field in Zambales indicated the use of the Mobile Air Defense Integrated System (MADIS) and Spyder systems to simulate the interception of aerial threats. The U.S. Army utilized the exercises to test new drone technology and 3D printing capabilities to support field operations.

Beyond air defense, the exercises included maritime and landing drills. Forces conducted counter-landing operations near the South China Sea, focusing on the ability to repel amphibious assaults and maintain territorial integrity.

Missile Firepower and Strategic Positioning

The Philippine Air Force (PAF) highlighted the country’s evolving role in regional security, stating that the Philippines is capable of boosting the missile firepower of its allies. This capability was demonstrated through various live-fire exercises across northern Luzon and Palawan province.

On April 27, 2026, a U.S. Army M142 High Mobility Artillery Rocket System (HIMARS) was fired during training in Palawan, showcasing the high-precision strike capabilities integrated into the joint force structure. U.S. Marines also participated in drills involving missile fire and the shooting down of drones.

The strategic placement of these drills—near the Taiwan Strait and the disputed waters of the South China Sea—underscores the focus on deterrence. The drills were conducted amid ongoing regional tensions and reports of expanded island constructions in the South China Sea.

Operational Objectives

The 2026 Balikatan exercises aimed to achieve several critical operational goals:

• Improving the interoperability of the Philippine, U.S., and Japanese militaries in a combined combat environment.
• Testing the effectiveness of counter-UAS systems against modern aerial threats.
• Practicing counter-landing and maritime security operations in contested waters.
• Evaluating the deployment of emerging technologies, such as 3D printing for logistics and new drone variants for reconnaissance.

The integration of Japanese forces marks a continuing trend toward a broader trilateral security framework in the Indo-Pacific, shifting the Balikatan drills from a bilateral U.S.-Philippine event into a more comprehensive regional defense exercise.
