From relics to robots: China turns Soviet jets into supersonic drones

China has converted its large stockpile of retired Soviet-era J-6 fighter jets, copies of the MiG-19 produced from the 1960s to 1980s, into supersonic unmanned combat drones. These drones, publicly unveiled at the Changchun Air Show in September 2025, retain the J-6’s Mach 1.3 speed and roughly 435-mile combat range but are now equipped with autonomous flight control, autopilot, and terrain-matching navigation systems. The conversion removes crew-related systems and adds weapon stations, enabling the drones to carry about 550 pounds of ordnance. With an estimated inventory of around 3,000 airframes, China’s program offers a cost-effective way to deploy massed drone attacks, particularly in a potential conflict over Taiwan. Military analysts express concern over the strategic implications of these drones, which could be used in large swarms for saturation strikes or as decoys to expose air defense sites. Taiwanese commentators warn that intercept
