A new study by Chinese military researchers has provided an unusually detailed look at how China might attempt to block Starlink internet access across Taiwan, outlining a scenario that relies on a vast deployment of electronic warfare drones. The findings, first highlighted by the South China Morning Post (SCMP), suggest Beijing would need somewhere between 1,000 and 2,000 specially equipped drones to jam Starlink signals island-wide. The research adds fresh urgency to ongoing concerns about China’s electronic warfare capabilities at a time of heightened geopolitical tension and deepening global reliance on satellite communications.
The report arrives amid growing speculation that China is also improving its ability to disrupt undersea communications cables—another critical vulnerability for island nations and global tech hubs. Taken together, these developments raise questions about how prepared the world is to counter potential large-scale interference with digital infrastructure.
Researchers Simulate How the PLA Could Disrupt Musk’s Expanding Satellite Network
The study was conducted by teams from Zhejiang University and the Beijing Institute of Technology, both of which are known for their extensive research ties with China’s defense sector. Their goal was to examine how the People’s Liberation Army (PLA) could limit or disable Taiwan’s access to Starlink, the rapidly expanding satellite internet network operated by SpaceX.
Starlink has grown into a global communications powerhouse, with more than 10,000 satellites currently in orbit. Its resilience and adaptability have made it a crucial asset in war zones—most notably in Ukraine, where it has helped maintain communications despite waves of Russian cyberattacks and missile strikes. Starlink’s role in that conflict has drawn intense attention in Beijing, which views Taiwan as a potential future battlefield where communications superiority could prove decisive.
To understand how Starlink coverage might be suppressed, the Chinese researchers modeled satellite positions, signal behavior and link variability over a simulated region equivalent in size to Taiwan. The simulations ran over a 12-hour window, capturing the fast-changing structure of Starlink’s mesh network—a system designed to prevent outages by passing data through many satellites rather than relying on a few.
A Massive Distributed Jamming Network, Not a Single-Point Attack
One of the central conclusions of the study is that Starlink’s decentralized design makes it highly resistant to traditional jamming. A single jammer or even a cluster of high-powered jammers would fail to disrupt the system because Starlink terminals can seamlessly switch between satellites overhead.
Instead, the researchers concluded that a large-scale, distributed jamming effort would be required—essentially a high-altitude grid of airborne electronic interference devices. These jammers, carried by drones, balloons, or aircraft, would operate in sync to create what amounts to an electronic fog covering major sections of Taiwan’s airspace.
The SCMP report notes that the jammers would need to be spaced between 3 and 6 miles apart in the air and would generate a shield stretching roughly 12 miles upward. The goal would be to overwhelm the communication links between Taiwan-based Starlink terminals and the passing satellites, choking off the network’s ability to maintain stable connections.
The simulation incorporated both wide-beam and narrow-beam jammers. Wide-beam devices cast a broad electronic noise field, while narrow-beam units target specific frequencies. Together, they would create sustained interference against a system designed to evade precisely this kind of assault.
Ideal Scenario Requires 935 Jammers, But Real-World Operation May Need 2,000
Under controlled theoretical conditions, the researchers estimated that approximately 935 perfectly optimized jamming nodes would be enough to impede Starlink’s signals across Taiwan. However, the study acknowledges that real-life equipment is rarely as capable or efficient as models assume. To compensate for this gap, the researchers suggest that the PLA would likely need around 2,000 drones equipped with jamming payloads to carry out such an operation under realistic battlefield conditions.
Deploying and coordinating a drone armada of this scale would represent a massive logistical challenge. The fleet would have to be launched, controlled and maintained while navigating contested airspace and countering Taiwan’s defensive measures. It would also require sustained electronic output to continuously disrupt connections—a task that places significant strain on drone batteries and onboard systems.
The researchers did not explore how the PLA might defend such a large drone fleet from anti-drone systems or missile interceptors, nor did the study address how long the jamming network would need to remain active. But the scale of the operation illustrates the seriousness with which China views Starlink as a strategic obstacle.
Taiwan’s Expanding Push for Drone Defense Capabilities
Any attempt by China to saturate Taiwan’s skies with drones would not happen unchallenged. Taiwan has been rapidly expanding its drone defense capabilities, driven by concerns about China’s growing use of unmanned aircraft for surveillance and potential offensive operations.
The island has invested heavily in both indigenous research and foreign partnerships to build advanced anti-drone tools. These include radar-guided air defense systems, electronic countermeasures and kinetic interceptors designed to take down drone swarms. Taiwan is also ramping up domestic drone production, both to strengthen its surveillance capabilities and to create its own deterrent against airborne threats.
Given Taiwan’s status as a global semiconductor powerhouse—with companies like TSMC, MediaTek and Asus forming the backbone of the world’s tech supply chain—the protection of its communications infrastructure is a national priority. Some analysts believe Taiwan may eventually pursue a layered air defense system reminiscent of Israel’s Iron Dome, but tailored for drones and electronic threats rather than rockets. Such a system could combine radar, jamming tools and aerial interceptors to neutralize large-scale swarms like the kind envisioned in the Chinese study.
