The reports are correct, in principle. The J-6 — a copy of the 1950s-vintage Soviet MiG-19 fighter — was once an attack plane and now serves in China strictly as a trainer and as a remote-controlled drone.
But it’s not an combat drone akin to the U.S. Predator or Reaper. No, the robo-J-6 is a target drone in the vein of the American QF-4 and QF-16. It’s meant to fly simple maneuvers as target practice for fighter pilots.
The real news here is the increasing realism of China’s aerial combat training — hence the high demand for robotic targets.
