Chinese engineers say they have found flaws in the latest US combat drone

  • Their analysis suggests its design prioritised weapons and fuel at the expense of manoeuvrability
  • Previous study had warned the drones could quickly form large swarms and pose a severe threat to the PLA in a conflict

Chinese aviation engineers say they have worked out some critical performance constraints of a stealth combat drone still under development in the United States.

Their estimates are based on some photos, openly available information and reverse-engineering software. They found that the XQ-58A Valkyrie, an unmanned combat aerial vehicle, was not good at aerial combat.

When making a U-turn, for instance, it can withstand a pull of only about 1.7 times that of gravity, according to their calculations. In a dogfight, most fighter jets need to brake against a force seven times that of gravity or higher.

This is a weakness, but the unusual design also signals a major break with tradition in the US military, suggesting gains in other areas, the researchers said.

“Through the inversion of the XQ-58A design process, it can be seen that with the continuous breakthroughs in artificial intelligence and network data transmission technology, the ‘loyal wingman’ represented by XQ-58A will gradually become the main force on the battlefield and become a new leading power in the transformation of the man-machine coordinated combat model,” senior engineer Lu Yuanjie and colleagues at the Shenyang Aircraft Design and Research Institute wrote in a paper published in domestic peer-reviewed journal Aircraft Design.
