China’s “Land Aircraft Carrier” Enhances Mid-Flight Drone Operations

Chinese Research Team Demonstrates Microwave Power Transfer for Drones

A research team from Xidian University in China has successfully tested a ground-based microwave system capable of powering drones mid-flight. This innovative technology allows fixed-wing aircraft to remain airborne for over three hours, as reported by The South China Morning Post. The findings were published on March 25, 2026, in a peer-reviewed Chinese journal.

Details of the Test

The system utilizes a vehicle-mounted microwave emitter that directs energy to an antenna array located on the underside of the drone. During trials, the setup maintained flight for fixed-wing drones for up to 3.1 hours at an altitude of approximately 49 feet. This low altitude indicates that the test was primarily a proof-of-concept rather than an operational system.

The primary engineering challenge was to keep the microwave beam aligned with the moving drone. The research team addressed this by integrating GPS positioning with a real-time tracking mechanism and the drone’s flight controls. Project lead Song Liwei emphasized that overcoming this alignment issue was crucial to the project’s success.

Advantages of Microwave Technology

Microwaves present distinct advantages over lasers for this application. While lasers can transmit energy over longer distances with greater precision, they are significantly affected by environmental factors such as fog and dust, which can degrade their effectiveness. Additionally, lasers emit an infrared signature that can reveal the drone’s position. In contrast, microwaves are more resilient in adverse weather conditions and have the potential to power multiple drones from a single emitter, enhancing scalability.

The Concept of a “Land Aircraft Carrier”

Chinese analysts have characterized this technology as a “land-based aircraft carrier.” This concept envisions an armored vehicle that serves as both a mobile launch point and a power source for a fleet of drones, similar to how an aircraft carrier operates at sea.

If implemented effectively, this technology could significantly alter the dynamics of drone warfare. Currently, the weight of batteries is a major limitation for small and medium tactical drones. Reducing battery size could allow for increased payload capacity for sensors, munitions, or electronic warfare equipment. Furthermore, eliminating the need for landing could enable continuous surveillance instead of intermittent coverage.

Xidian University, located in Xi’an, has historical ties to the Chinese Communist Party’s military radio school established in 1931. It has been under the oversight of China’s State Administration of Science, Technology and Industry for National Defense since 2008. The Australian Strategic Policy Institute has classified it as a high-risk defense research institution, indicating that its work on microwave and antenna systems has direct implications for the People’s Liberation Army (PLA).

Comparative Developments in the United States

While the United States is not lagging in this field, it is pursuing a different approach. The Defense Advanced Research Projects Agency (DARPA) has funded various wireless power transfer programs, including both radio-frequency and laser-based technologies. Private companies are also exploring laser charging for drones.

The U.S. strategy has favored lasers due to their precision, which is advantageous for long-range, single-drone missions. Conversely, China’s microwave approach is more suited for swarms and short-range persistent coverage. Both technologies address different operational needs, and both nations are aware of these distinctions.

Implications for Future Drone Warfare

The recent demonstration highlights significant advancements in drone technology. The tested altitude of 49 feet and endurance of 3.1 hours may seem modest, but they underscore the successful proof of concept for maintaining a stable power supply to a moving drone. This achievement paves the way for future engineering iterations to enhance altitude and range.

Military planners are likely considering the implications of a wireless charging vehicle, which could be designed to be robust, mobile, and cost-effective enough for mass deployment. If the PLA can integrate this technology into a vehicle platform within the next five years, it could provide continuous drone coverage for ground units without the logistical challenges associated with battery swaps and forward launch points.

Moreover, this development raises questions about future drone designs. Currently, tactical drones rely on batteries that constitute a significant portion of their takeoff weight. Reducing this dependency could lead to smaller drones with extended ranges or increased payload capacities, complicating the current dynamics of counter-drone strategies.

While this technology is not yet operational, the gap between research and prototype development is narrower than for many advanced drone technologies, as the components involved are well-established. The successful demonstration by Xidian University indicates that the integration of these technologies is feasible.
