In a move with significant geopolitical implications, the United States has deployed its advanced F-35 Lightning II stealth fighter jets to the Philippines for the first time, marking an unprecedented step in military cooperation between the two countries. This comes at a time when tensions continue to rise in the South China Sea amid China’s aggressive maritime claims and frequent confrontations with Philippine naval vessels.
What Does The Deployment Involve?
According to US Indo-Pacific Command (INDOPACOM), a squadron of F-35A jets from the US Air Force’s Pacific fleet arrived at Clark Air Base in Luzon for joint exercises under Operation Cope Thunder, scheduled over the next three weeks. This deployment is being described as:
- The first operational presence of fifth-generation stealth fighters in Philippine territory
- A demonstration of US commitment to the Enhanced Defense Cooperation Agreement (EDCA) signed in 2014 and expanded recently
- An effort to increase interoperability and joint readiness between the US and Philippine armed forces
Strategic Context: Why Now?
Rising South China Sea Tensions
The deployment follows:
- A series of near-collision incidents between Chinese Coast Guard and Philippine vessels in disputed waters near the Second Thomas Shoal and Scarborough Shoal
- Chinese naval drills simulating island capture and amphibious operations, raising alarm in Manila and Washington
- Philippine President Ferdinand Marcos Jr’s recent assertion that “an attack on any Philippine vessel will invoke the US Mutual Defense Treaty obligations”
Growing China-US Rivalry
This move is also viewed as part of Washington’s Indo-Pacific strategy to counterbalance Chinese military expansion. The F-35 deployment complements:
- US Marines rotational presence in northern Luzon
- Bilateral patrols in the South China Sea with Japan and Australia
- Recent announcements to expand joint naval exercises like Balikatan
Capabilities Of F-35: Why It Changes The Strategic Equation
| Feature | Details |
|---|---|
| Stealth | Low radar cross-section, making detection by Chinese SAM systems difficult |
| Multirole | Capable of air superiority, electronic warfare, precision strikes, and intelligence gathering |
| Network-Centric Warfare | Can fuse data from multiple sensors to guide other assets in the battlespace |
| Range & Payload | Operational radius of ~1,100 km with advanced guided munitions |
Experts believe the F-35’s ISR (intelligence, surveillance, reconnaissance) capability could enhance domain awareness over contested islands and reefs in the South China Sea, critical for early warning and deterrence.
China’s Reaction
Beijing’s Foreign Ministry condemned the deployment, stating:
“The US is militarising the South China Sea and threatening regional peace under the guise of freedom of navigation. China will take necessary measures to safeguard its sovereignty.”
PLA Navy spokespersons also announced fresh live-fire drills near Hainan and Paracel Islands, signalling military pushback.
Philippine Military View
Philippine Air Force Chief Lt Gen Stephen Parreño welcomed the deployment:
“This is a landmark in our modernisation efforts. Training with the world’s most advanced fighters improves our deterrence capability.”
However, some local lawmakers cautioned the Marcos government against “getting dragged into great power conflicts”.
Timeline Of Recent US-Philippine Military Developments
| Year | Event | Significance |
|---|---|---|
| 2014 | EDCA signed | Gave US access to five Philippine bases |
| 2021 | EDCA reaffirmed | Under President Duterte, with caution |
| 2023 | Four new EDCA sites added | Strengthened US strategic footprint |
| 2024 | Largest ever Balikatan exercise | Included HIMARS, F-16s, Patriot missile batteries |
| 2025 | First F-35 deployment | Marks a qualitative leap in joint operations |
Regional Reactions
Japan and Australia
Both nations, US allies with their own tensions with China, welcomed the move. Japan’s defence ministry stated it “underscores allied readiness to maintain regional peace and rule of law”.
ASEAN
Responses remain mixed. While Vietnam, Malaysia, and Indonesia privately share Philippine concerns about Chinese maritime claims, they remain wary of overt military alignment with the US.
Defence Analysts Weigh In
| Expert | Comment |
|---|---|
| Dr. Zack Cooper (Hudson Institute) | “Deploying F-35s enhances deterrence and signals to Beijing that Washington’s security commitments to Manila are credible and operationally potent.” |
| Prof. Renato De Castro (Manila-based analyst) | “It narrows the capability gap with China’s J-20s and boosts confidence in defending maritime zones.” |
| Col. Li Nan (Chinese military scholar) | “F-35s near Chinese shores increase risks of accidental confrontation, undermining stability.” |
The China Factor: J-20 Vs F-35
China has deployed its J-20 fifth-generation stealth fighters in the Eastern and Southern Theatre Commands. While Chinese media often tout J-20’s superiority, Western analysts note:
- F-35 has higher production maturity, global logistical networks, and combat-proven systems
- J-20 remains largely an air superiority platform with evolving multirole capability
This qualitative contest adds another layer of tension to the South China Sea standoff.
Implications For India
India has growing defence ties with both the US and the Philippines. New Delhi’s “Act East” policy aligns with Manila’s efforts to uphold maritime freedom of navigation, and the F-35 deployment signals US resolve in countering Chinese assertiveness, indirectly benefitting India’s own Indo-Pacific objectives.
What’s Next?
Experts forecast:
- More joint air drills including US, Philippine, and potentially Australian F-35 squadrons
- Strengthening of Philippine Integrated Air Defense Systems with US technological support
- Likely Chinese grey zone tactics intensification through maritime militia and Coast Guard deployments to counter increased allied presence
Conclusion
The first-ever deployment of F-35s to the Philippines marks a critical milestone in US-Philippine defence ties, adding significant deterrent value amid rising Chinese aggression in the South China Sea. While it enhances Manila’s defensive confidence, it also raises the risk of inadvertent confrontations, requiring calibrated diplomacy alongside robust defence preparedness.
