Commentary: Zhuhai Reveals Evolution Of Chinese Military Aircraft

Bands of heavy rain and a layer of smog hung over the 600,000 visitors to Zhuhai International Airport in mid-November for the China International Aviation & Aerospace Exhibition. But soaking, murky weather could not obscure another stunning display of progress by China’s aerospace industry.

Held biennially on the southeastern coast, a short ferry ride from Hong Kong, the four-day event—also known as the Zhuhai Airshow—stopped short of revealing all of China’s aerospace secrets, including the still-unreleased shape and status of the Xian H-20 stealth bomber.

Even so, the show served as the public, international debut of China’s second operational stealth fighter as well as a showcase for a diversifying portfolio of uncrewed combat air vehicles (UCAV) and a stage for ambitions in aerospace technology development. mockup of the six-year-old CH-7 concept appeared alongside video of the prototype’s first flight.

• An early mockup of the China Aerospace Science and Technology Corp. CH-7 UCAV debuted at Zhuhai in 2018, but a redesigned model arrived this year alongside a state-sponsored documentary film revealing the formerly secret prototype’s first flight.
• The mysterious Cloud Shadow CS-5000T was on full display this year, but the stealthy UCAV with an ample internal weapons bay appeared first in 2022, albeit with its aft fuselage shrouded from view.

The Cloud Shadow example offers a rare glimpse into China’s protean process for revealing semi-secret aerospace technology.

The first clue of the CS-5000T’s existence came at the 2018 Zhuhai Airshow. A subscale prototype of an identical design appeared in the Avic section of the static display—but lacked identification. Hours later, the model vanished without explanation.

The full-scale, Chengdu-made prototype subsequently appeared at Zhuhai four years later, albeit with the tail obscured. Video of the identical-looking aircraft in flight appeared online last year but with no official acknowledgment or explanation.

The Chinese Air Force already operates the Hongdu GJ-11 Sharp Sword, a UCAV with similar stealthy features and dimensions. Why, however, would the Chinese Air Force simultaneously fund Hongdu’s UCAV and Chengdu’s CS-5000T, both stealthy designs seemingly in the 5-ton weight class?

Perhaps the answer can be found closer to home. The U.S. Air Force also is developing prototypes of stealthy, 5-ton UCAVs under the Collaborative Combat Aircraft (CCA) program. The Air Force-funded aircraft—the General Atomics Aeronautical Systems Inc. Gambit and Anduril Industries Fury—are not stealthy, flying-wing aircraft, but the rejected proposals for the CCA Increment 1 contract from Boeing, Lockheed Martin and Northrop Grumman likely were. There is precedent for funding competing prototypes of stealthy UCAVs.
