China’s Race to ‘Delink’ Starlink: A New Era of Space Warfare?
Chinese military experts are intensifying efforts to counter the Starlink satellite network, recognizing its potential to aid Taiwan in a potential conflict. Elon Musk has highlighted the difficulty of disabling the network, noting the sheer number of satellites – over 2,000 – and the rapid launch capabilities of SpaceX. However, China is responding with innovative technologies aimed at neutralizing this advantage.
The 20GW “Starlink Killer”: A Ground-Based Threat
Researchers at the Northwest Institute of Nuclear Technology in Xian, Shaanxi province, have developed the TPG1000Cs, a high-power microwave (HPM) weapon capable of delivering 20 gigawatts of power for up to one minute. This device is touted as the world’s first compact driver for an HPM weapon, significantly smaller and more powerful than previous iterations like Russia’s Sinus-7, which weighed 10 tons and operated for only a second.
The TPG1000Cs, weighing only 5 tons and measuring 4 meters in length, is designed to be mobile, potentially installed on trucks, warships, planes, or even satellites. Chinese scientists believe a ground-based microwave weapon with an output exceeding 1GW could seriously disrupt or damage Starlink satellites in low Earth orbit.
Engineering Innovations Behind the Power
The development of the TPG1000Cs involved several key design advancements. Researchers reduced the system’s weight by a third by utilizing aluminum alloy instead of high-strength steel. They also etched wavy grooves into insulating plates, mimicking winding mountain roads to prevent electrical discharges and extend the surface path for energy flow.
the device employs a dual-U-shaped structure that allows energy to bounce back and forth, achieving the same performance in half the space compared to traditional straight-tube energy storage components.
Beyond Microwaves: A Multifaceted Approach
China’s pursuit of “Starlink-killer” weapons extends beyond high-power microwaves. Researchers have published numerous papers exploring methods to disrupt or destroy Starlink satellites. Simulations have indicated that as few as 99 Chinese satellites could approach and potentially neutralize 1,400 Starlink satellites within 12 hours, equipped with tools for tracking, reconnaissance, and potential engagement.
Directed-energy weapons, including lasers and microwaves, are emerging as the preferred method for countering Starlink. Prior to the TPG1000Cs, Chinese scientists developed a compact power source in 2023 to reduce the size of HPM weapons, capable of producing up to 10 gigawatts of power. In January 2025, reports surfaced regarding a high-power microwave weapon capable of generating electromagnetic pulses similar to a nuclear explosion, utilizing phased-array transmission technology for focused energy delivery.
The Vulnerability of Lower Orbits
SpaceX’s decision to lower the orbital altitude of Starlink satellites to reduce collision risks inadvertently increases their vulnerability to ground-based directed-energy weapons. Chinese reports suggest that deploying the TPG1000Cs in space would make attacks even more deadly and difficult to detect.
Starlink’s Role in Modern Warfare & China’s Concerns
China’s concern stems from the demonstrated effectiveness of Starlink in providing crucial communication and internet access during conflicts. Following Russia’s invasion of Ukraine in 2022, Elon Musk activated Starlink for Ukrainian forces, providing essential connectivity for operations. This success prompted Moscow to develop countermeasures against Starlink signals.
Chinese scholars have cautioned that China would face “severe tests” in responding to the Starlink network if it were used to provide US military assistance to Taiwan during a crisis. The PLA has also explored utilizing submarines equipped with megawatt-class solid-state lasers to target Starlink satellites from submerged positions.
