A large Chinese military drone has conducted at least 23 flights since August over the South China Sea while broadcasting false transponder signals, making it appear to be entirely different aircraft, according to flight-tracking data reviewed by Reuters. Analysts say the tactic represents a significant evolution in China’s grey-zone operations and could serve as a rehearsal for future conflict scenarios involving Taiwan.
The aircraft used the call sign YILO4200, linked by open-source intelligence analysts to the Wing Loong 2 long-endurance unmanned aerial vehicle. Instead of transmitting its own identity, it broadcast registration codes belonging to unrelated planes, including a Belarusian cargo jet and a British Royal Air Force fighter.

Most frequently, the drone appeared on public flight-tracking platform Flightradar24 as an Ilyushin Il-62 cargo aircraft operated by Belarus-based Rada Airlines. At other times, it masqueraded as a Royal Air Force Typhoon fighter jet, a North Korean passenger aircraft, or a Gulfstream executive jet.
The real Belarusian Il-62 was active during the same period under a different call sign and was at one point airborne simultaneously with the Chinese drone mimicking its identity. That overlap suggests the masking was deliberate rather than accidental.
Aviation analysts note that aircraft identification codes are governed by the International Civil Aviation Organization and broadcast through transponders using a unique 24-bit address. While these addresses are publicly known, experts say it is technically possible to reprogram a transponder to transmit a different code.
Strategic Flight Paths
The drone typically flew out of Hainan’s Qionghai Boao International Airport, a dual-use civilian and military facility. Flight paths headed east toward the Philippines near the disputed Paracel Islands, south along Vietnam’s coast, and into areas of dense naval activity.
The aircraft often traced star- or hourglass-shaped patterns consistent with long-duration surveillance missions. Analysts familiar with the data said the areas covered included sensitive maritime zones frequented by submarines and major naval traffic.
Two flights stood out. In early August, the drone switched identities multiple times mid-flight, briefly transmitting the code of an RAF Typhoon before cycling through other aircraft identities and eventually landing under the Belarusian cargo plane’s registration. In November, it was airborne posing as the Rada Il-62 while the real Belarusian aircraft departed from Eastern Europe toward Tehran.
Beyond Civilian Tracking
While such masking may not fool military-grade radar systems or experienced air traffic controllers, security experts say it could create confusion in fast-moving conflict scenarios. Even momentary uncertainty can disrupt targeting cycles or complicate identification processes in highly automated warfare environments.
Analysts describe the operations as part of a broader effort by China to refine electronic warfare and deception capabilities. By exploiting publicly visible tracking systems in real time, Beijing could be testing how adversaries respond to manipulated data streams.
Possible Taiwan Rehearsal
Several of the drone’s routes passed through waters south of Hainan near Chinese submarine bases and extended toward the Bashi Channel between Taiwan and the Philippines a strategic chokepoint for access to the Pacific.
When overlaid on a map of Taiwan, the flight paths align with key military and political sites, including areas near Taipei and along the island’s southern coastline. Eastern trajectories brought the drone close to Japanese and U.S. military bases in Okinawa and the Ryukyu island chain.
Security analysts say the pattern resembles operational rehearsal rather than routine patrol. The flights appear less like conventional exercises and more like preparations for scenarios in which confusion, deception and rapid decision-making would be critical.
Escalating Grey-Zone Pressure
China has steadily expanded its military presence across the South China Sea and around Taiwan in recent years. Such operations fall short of open conflict but increase pressure on regional rivals and test response thresholds.
The masking of drone identities adds a digital and psychological dimension to that strategy. If tensions over Taiwan were to escalate, the ability to muddy real-time situational awareness even briefly could offer a tactical advantage.
China’s defence ministry did not respond to questions about the flights. But the scale, repetition and complexity of the operations suggest a calculated effort to integrate deception into future conflict planning, particularly in scenarios centered on Taiwan.
