Overview
The J-20 ‘Mighty Dragon’ is China’s fifth-generation stealth fighter, making China the second country (after the US) to field an operational stealth combat aircraft. Its large, long-range design suggests a focus on striking high-value targets like tankers and AWACS rather than pure dogfighting.
Design & Development
The J-20 features a large delta wing with canards, DSI (Diverterless Supersonic Inlet), internal weapons bays, and all-aspect stealth shaping. It is significantly larger than the F-22, suggesting emphasis on range and payload. Initial production uses Russian AL-31F engines, with indigenous WS-15 engines planned for full supercruise capability.
Operational History
Entering service in 2017, the J-20 is deployed with multiple PLAAF brigades. Production has accelerated, with estimates of over 200 aircraft delivered. The twin-seat J-20S variant has been spotted, potentially serving as a weapons systems officer platform for controlling loyal wingman drones.
Armament
- Internal weapons bays (stealth):
- PL-15 long-range BVR missiles
- PL-10 short-range IR missiles (side bays)
- External (non-stealth):
- PL-21 ramjet-powered ultra-long-range
- Various PGMs
Large internal bays suggest anti-AWACS/tanker role with very long-range missiles.
