China says it has dramatically increased production efficiency for key components of its advanced J-20 stealth fighter jet using a nearly fully automated “dark factory” where AI systems and autonomous machines operate around the clock with minimal human involvement.
The facility, operated by Chengdu Aircraft Corporation, reportedly more than doubled production efficiency after introducing AI-driven manufacturing systems, autonomous transport vehicles, robotic inspection tools, and interconnected machinery capable of communicating through a unified digital system. The factory now runs for more than 21 hours a day at maximum operating capacity while reducing human labor requirements by over 80%, according to South China Morning Post.
So-called “dark factories” are industrial facilities designed to operate with little or no direct human supervision. Because humans are rarely present on the production floor, lighting and other workplace infrastructure can be minimized, reducing energy costs while allowing continuous automated operation.
In this case, the factory is producing structural components for the J-20 “Mighty Dragon,” China’s flagship fifth-generation stealth fighter often viewed as Beijing’s counterpart to the American Lockheed Martin F-22 Raptor.
According to factory officials, the manufacturing process previously required multiple workers rotating through overnight shifts just to keep systems running continuously. Now autonomous vehicles transport materials across the facility while precision-controlled machinery fabricates aircraft components with limited direct oversight.
The plant also uses AI-assisted quality control systems. Robotic inspection equipment scans components and automatically generates reports, reducing the amount of manual review needed during production.
One major technical challenge reportedly involved integrating machines that originally operated using incompatible software systems. Engineers say the facility now runs on a unified digital communication framework that allows equipment across the factory to exchange information and coordinate tasks remotely.
The rapid expansion of automated aerospace manufacturing comes as China continues accelerating military modernization efforts. The J-20 officially entered combat service in 2018, and production has steadily increased alongside upgrades to engines, radar systems, avionics, and AI-assisted combat capabilities.
China has also introduced a two-seat version of the aircraft and is reportedly testing future sixth-generation fighter designs including the J-36 and J-50 platforms.
Defense analysts estimate the People’s Liberation Army may already operate roughly 300 J-20s, with projections suggesting that number could approach 1,000 by 2030. That expansion is part of a broader competition with the United States, which continues deploying large numbers of Lockheed Martin F-35 Lightning II fighters across the Asia-Pacific region.
The development also highlights how AI and industrial automation are increasingly becoming strategic military assets, not just commercial technologies. Faster aircraft production, lower labor dependence, and continuous manufacturing capability could significantly affect how major powers scale military production in future conflicts.
