China is officially the second nation in the world (U.S. was the first) to have an operational fifth-generation fighter unit. The country’s first J-20 stealth fighter unit is now operational in the 176th Brigade, a unit in the China Flight Test Establishment (CFTE). The public debut comes just under six years from its prototype flight, a speedy delivery by any measure.
The debut of the first operational J-20s will help the CTFE better understand the combat capabilities stealth fighters bring to the People’s Liberation Army Air Force (PLAAF). Next steps will likely be training and exercises against other Chinese fighters, as well as testing for future design upgrades.
Judging from observed sightings of LRIP J-20s in the past year, there could be between eight to twelve J-20s now stationed at Dingxin airbase, enough to set up a squadron for combat operations.
A variety of internet reports have covered the J-20s joining the unit: At least two J-20s were observed in a late November 2016 satellite photo of the Dingxin air base, a CFTE establishment. December 2016 photos on the Chinese Internet forums show J-20s with operational serial numbers painted on the vertical tailfins.
Chinese aviation expert Dafeng Caoposted that the PLAAF received six J-20s on Dec. 12, which makes sense considering a photo surfaced earlier this month that showed three LRIP J-20s on the runway at the Chengdu Aircraft Corporation factory, possibly ready for that transfer.
Previously, several LRIP J-20s were already produced starting in late 2015, with four J-20s (production airframes 2101-2104) delivered by June 2016, and at least several more J-20s produced after that.
While intriguing to see J-20s operational, these will not be the final version of the J-20’s design. While the plane currently uses advanced avionics including AESA radar and electro-optical distributed aperture system, it uses a high-performance variant of the Russian AL-31 turbofan engine. Once the supercruise-capable WS-15 engine enters service in 2019-2021, large-scale production of faster J-20s will commence.
