Photos: China’s New Carrier-Based Early Warning Aircraft Spotted on First Flight

The new carrier-based aircraft took to the skies for the first time over Shaanxi’s Xi’an last week, the Xi’an-based magazine Ordnance Industry Science Technology reported. However, the Chinese Defense Ministry has made no official statement or verification of the event to the press.

Photos of the prop-driven aircraft in flight appeared on social media just as commercial satellite photos of the KJ-600 sitting on the tarmac at a Xi’an air base began to circulate as well.

​However, the plane’s layout was not that much of a mystery for military observers: an experimental design used to build the KJ-600, called the JZY-01, appeared in 2018. That aircraft was in turn based on the Russian Au-24 transport aircraft, which at 77 feet long is far too big to launch from an aircraft carrier.

Much about the KJ-600’s design is clearly inspired by the Grumman E-2 Hawkeye, a well-proven AEW aircraft in use by the US Navy and many of its allies since the 1960s.

This is likely because the Hawkeye’s design is already optimized for its role: its propeller engines allow it to loiter for up to four hours high above the carrier battle group, where its huge radome mounted above the fuselage can dramatically extend the radar range of the fleet. Its slender fuselage leaves enough room for between four and six crew members to operate, while still being small enough to fit below decks on the carrier, and its four-finned tail provides it with superior stability as it lugs around that huge radome.

The Soviet Union’s proposed Yak-44 AEW aircraft would have used a remarkably similar design to the Hawkeye as well.

​However, the KJ-600 will almost certainly not fly from the Shandong or the Liaoning, the People’s Liberation Army Navy’s (PLAN) only two aircraft carriers at present. A heavy plane like the Hawkeye doesn’t generate enough thrust to survive the low-speed launch off the ramp on the front of the flight deck, requiring instead the more powerful catapult launching system used by US aircraft carriers - and featured on the PLAN’s upcoming Type 003 carrier. That warship is under construction in Shanghai and is expected to be completed in 2021.

China’s carriers do have a form of AEW aircraft in specially modified Z-18J helicopters, but they have a far shorter range than the KJ-600 would likely have: some 200 miles versus a 500-mile radius. However, even that is better than the carrier’s tower-based radar, which cannot see beyond the horizon, just 12 miles away.

The KJ-600 isn’t the only new carrier-based aircraft under development in China: in July, the Chinese Aeronautical Establishment, the research and development branch of the Aviation Industry Corporation of China, announced it would be teaming up with Shenyang Aircraft Corporation to test a new carrier-based aircraft later this year. As Shenyang made the FC-31 “Gyrfalcon” stealth aircraft, which has been widely anticipated to become China’s new carrier-based fighter, it has been assumed the announcement refers to the FC-31.

Like the KJ-600 and the E-2 Hawkeye, the FC-31 has also seen comparisons drawn with the United States’ F-35 fighter, but as Sputnik reported, their similarities are superficial and do not warrant the accusation that it was copied from the Lockheed Martin jet using stolen designs, as former US national security adviser John Bolton has claimed.
