Overview
- Reuters analysis of Flightradar24 data logged at least 23 YILO4200 missions from August through Feb. 15, flying out of Qionghai Boao over key South China Sea corridors.
- The drone broadcast false 24‑bit transponder addresses to appear as other aircraft, most often a Belarusian Rada Airlines Il‑62, and at times a RAF Typhoon, a North Korean Il‑62 or a Gulfstream jet.
- Flight paths showed prolonged loitering in star and hourglass patterns across submarine‑frequented waters and toward the Bashi Channel approaches to Taiwan and the Philippines.
- Open‑source researchers attribute YILO4200 to the long‑endurance Wing Loong 2 UAV, with satellite imagery showing large drones and expanding support infrastructure at Boao airport.
- Flightradar24 reported it had not seen comparable systematic masking, China offered no substantive comment, and experts say the activity could be testing decoys or rehearsing Taiwan contingencies.
