U.S. F-22 Stealth Fighters Operated Near South China Sea to Reinforce Allied Air Combat Strategy.

U.S. F-22 Raptors operated from Basa Air Base in the Philippines during Cope Thunder 26-1, placing fifth-generation stealth airpower close to the South China Sea, the Luzon Strait, and the Taiwan contingency environment. The deployment strengthens forward air combat readiness as China expands military pressure across the first island chain.

The exercise showed that U.S. and Philippine forces can integrate high-end fighters, sustain sorties from a forward base, and rehearse rapid air operations in a contested theater. For Washington and Manila, the Raptor’s presence reinforces deterrence, air defense cooperation, and the ability to counter advanced Chinese combat aircraft in the Indo-Pacific.

The U.S. Defense Visual Information Distribution Service published on April 29, 2026, imagery showing a U.S. Air Force F-22 Raptor pilot from the 199th Air Expeditionary Squadron taking off from Basa Air Base in the Philippines during Exercise Cope Thunder 26-1. The training sortie, conducted on April 6, placed one of America’s most capable fifth-generation stealth fighters in a strategic location close to the South China Sea, the Luzon Strait and the wider Taiwan contingency environment. Beyond a bilateral exercise, the deployment sent a visible message of U.S. airpower readiness at a time when China is expanding military activity across the first island chain.

Exercise Cope Thunder 26-1 was conducted from April 6 to 17, 2026, and involved U.S. and Philippine forces training together in combined air operations, fighter integration and expeditionary support. According to DVIDS, more than 90 Airmen from the 199th Air Expeditionary Squadron deployed for the exercise, bringing Hawaii-based F-22 Raptor airpower to the Philippines and flying alongside Philippine FA-50PH fighter aircraft. The squadron flew more than 30 sorties as part of a combined force of over 2,800 U.S. and Philippine personnel, while the exercise also included planning, maintenance, logistics and support activities needed to sustain flight operations from a forward location.

The presence of the F-22 at Basa Air Base gives Cope Thunder 26-1 a significance that goes beyond routine interoperability. Luzon sits at the northern edge of the Philippines, facing the Bashi Channel and the Luzon Strait, two areas that would be critical in any crisis around Taiwan. To the west, Philippine airspace opens toward the South China Sea, where China has increased naval, coast guard and military aviation activity in recent years. Training the F-22 from this geography allows U.S. pilots, maintainers and planners to rehearse the operational demands of deploying stealth airpower closer to potential flashpoints rather than relying only on major rear bases in Hawaii, Alaska or the continental United States.

The F-22 Raptor remains the U.S. Air Force’s dedicated air-dominance platform, combining stealth, supercruise, maneuverability and integrated avionics. The U.S. Air Force describes the aircraft as designed to project air dominance rapidly and at great distances, defeat threats that attempt to deny access to U.S. forces, and use its sensor suite to track, identify and engage air-to-air threats before being detected. In its air-to-air configuration, the Raptor can carry six AIM-120 AMRAAM missiles and two AIM-9 Sidewinders internally, preserving its low-observable profile while maintaining a high-end interception role.

This capability is directly relevant to the Indo-Pacific operating environment, where China is fielding a growing mix of J-20 stealth fighters, J-16 multirole combat aircraft, H-6 bomber variants and airborne early warning platforms. For the United States, the F-22’s role in the region is not limited to air combat. In a high-end scenario, Raptors could also operate as forward sensors, air-superiority escorts and first-entry aircraft supporting bombers, tankers, surveillance platforms and allied fighters. From the Philippines, the F-22 can train in a theater where distance, access, airbase survivability and command-and-control links are central to any realistic operational plan.

The exercise also reflects how U.S. and Philippine air cooperation is adapting to China’s growing operational tempo. CSIS reported in February 2026 that China’s military activity increased in 2025 across the Taiwan Strait, the South China Sea, near Japan and beyond the first island chain. The same assessment noted record PLA activity around Taiwan, 163 recorded PLA operations in the South China Sea and intensified Chinese pressure on the Philippines, particularly around Scarborough Shoal. Against this background, F-22 training in the Philippines gives the United States and its ally a practical way to refine air defense coordination, fighter communication and rapid response procedures in a region already exposed to Chinese military pressure.

The deployment also gives U.S. forces an opportunity to test the expeditionary side of stealth fighter operations. A fifth-generation fighter is not only defined by its radar cross-section, sensors or weapons; it also depends on secure logistics, protected maintenance, reliable fuel supply, data connectivity and the ability to generate sorties under pressure. DVIDS reported that U.S. Army forces established expeditionary fuel systems during Cope Thunder 26-1, demonstrating how joint support elements help extend the reach and endurance of air operations in austere conditions. This is a key point for any future Indo-Pacific scenario, where large fixed bases could be vulnerable to missile strikes and dispersed air operations may become essential.

For Beijing, the appearance of the F-22 in the Philippines is likely to be read as part of a broader U.S. effort to strengthen the first island chain with allies and forward-deployed capabilities. For Manila, it reinforces the value of the U.S. alliance at a time when Chinese pressure in the South China Sea continues to affect Philippine security planning. For Washington, it provides a platform to sharpen tactics against high-end Chinese aviation, including stealth fighters, long-range bombers and aircraft supported by airborne early warning and missile networks. The Raptor’s presence at Basa Air Base shows that U.S. airpower planning in the region is increasingly focused on forward access, allied integration and the ability to operate inside a contested battlespace.

The participation of the F-22 Raptor in Cope Thunder 26-1 shows that U.S.-Philippine air exercises are no longer limited to routine alliance training. By operating from Basa Air Base, America’s most capable air-superiority fighter trained in a location directly connected to the South China Sea, the Luzon Strait and the wider Taiwan contingency environment. The deployment sends a clear operational message: the United States is preparing its stealth fighter force to counter Chinese combat aircraft, reinforce allied air defense planning and preserve freedom of action in the Indo-Pacific. In a region where airpower, missile reach and forward access are becoming decisive, the Raptor’s presence in the Philippines demonstrates that Washington is adapting its tactics to the geography of a possible future crisis.
