War Rumours, Threats: Bad News: China’s J-20 Stealth Fighter Has New Long-Range Missiles. Fifth (5) Generation.

The Chinese People’s Liberation Army Air Force made waves at the 2018 Zhuhai Airshow with the latest showing of their flagship fifth-generation stealth fighter, the J-20.

As is common with airshow coverage, large swaths of the ensuing commentary focused on the J-20’s handling and maneuverability as it performed a series of rolls and a climb. But this elides what is perhaps the most significant aspect of the J-20’s Zhuhai showing: its weapons system.

During the performance, the J-20 opened its missile bay doors to reveal four PL-15 missiles accompanied by two PL-10 missiles on either side. The PL-15 is a long range air-to-air missile slated to enter service in 2018. Outfitted with an active electronically scanned radar and featuring a reported maximum range of up to 300 km, the PL-15’s impressive specifications place it in the ranks of the top air-to-air missiles along with the European Meteor missile and Russian K-37M.

The PL-15’s effective range in actual aerial engagements is certain to be lower than the maximum range 300 km, but is nonetheless much higher than its American AIM-120 AMRAAM counterpart’s estimated 180 km or less. American general Herbert Carlisle voiced serious concerns in 2015 when the development of the PL-15 entered the public knowledge: “Look at our adversaries and what they’re developing, things like the PL-15 and the range of that weapon.” General Carlisle raised the same issue in an interview with FlightGlobal: “The PL-15 and the range of that missile, we’ve got to be able to out-stick that missile.”

The American F-22 and F-35 fighters are now equipped with the latest AIM 120-D missiles, but a massive range deficit remains nonetheless. The challenge of the PL-15 comes on the heels of questions about the uncertain future of the aging AMRAAM system. As Captain James Stoneman put it to the National Interest: “Currently there is no program of record for a follow-on… we’ve probably close to maxing it out.” Development of the latest Block III iteration of the short range AIM-9X was cancelled, and Raytheon struggles with a necessary AMRAAM refresh.

The J-20’s two side-mounted PL-10 missiles, while less conspicuous than their long range counterpart, are a key factor in the J-20’s operational versatility. A short-range infrared air-to-air missile, the PL-10 can be fired at off boresight angles of 90 degrees using the J-20’s Helmet Mounted Display (HMD). In other words, the PL-10’s on the J-20 can be fired in the direction that the pilot points their head.
