US shifts South China Sea reconnaissance towards drones and Philippines: think tank

**The US military is fundamentally reshaping its South China Sea posture, shifting from high-profile carrier deployments to a more persistent, drone-heavy reconnaissance presence based in the Philippines.** A Beijing-based think tank reports that US freedom-of-navigation operations in the disputed waters dropped to just two in 2024, matching 2023's low but far below the six conducted in 2022. This shift is driven by growing maintenance backlogs and the diversion of large naval assets to the Middle East conflict, forcing Washington to adapt its regional strategy. Despite these constraints, the report emphasizes that the Asia-Pacific remains the US military's most critical strategic theater, with operations expected to become more aggressive and provocative.</p><p class="summary-lead">**The centerpiece of this new approach is a dramatic increase in aerial reconnaissance, with drones now accounting for 30% of all US surveillance flights in the South China Sea.** Last year, the US launched 1,200 close-in reconnaissance sorties, with the main growth coming from MQ-9 Reaper drones and P-8A aircraft operating out of the Philippines' Clark Air Base. This base, located much closer to the contested waters than the traditional hub at Kadena Air Base in Japan, has become a critical forward operating location. The report notes that 38% of all US reconnaissance launches targeting Scarborough Shoal and the Spratly Islands originated from the Philippines.</p><p class="summary-lead">**This strategic pivot reflects a deliberate US intent to leverage uncrewed systems and allied basing to create a more resilient and persistent intelligence, surveillance, and reconnaissance (ISR) network.** The think tank describes drones as the "core pillar" supporting America's Indo-Pacific strategy, enabling continuous monitoring without the political and logistical costs of deploying large surface vessels. The US-Philippine cooperation in maritime domain awareness is a clear signal of Washington's intent to build a distributed, networked presence that is harder for adversaries to counter. This shift also allows the US to maintain a high operational tempo even as its carrier fleet faces competing global demands.</p><p class="summary-lead">**The implications are significant: a lower-profile but more intrusive US military presence that could escalate tensions while reducing the risk of direct naval confrontation.** By relying on drones and allied bases, the US can conduct persistent surveillance and intelligence-gathering that Beijing views as provocative, potentially triggering more aggressive Chinese counter-measures. The report warns that this new posture may lead to more frequent and bolder reconnaissance operations, particularly around Chinese naval assets like the aircraft carrier Fujian. Meanwhile, the US is also deepening alliance building, conducting 122 large-scale military exercises in the region last year, 116 of which were bilateral or multilateral.</p><p class="summary-lead">**What to watch next:** Whether the Trump administration accelerates this drone-and-allies model, and how China responds to the increased tempo of uncrewed surveillance flights operating from Philippine soil.
