Chengdu J-20
The Chengdu J-20 is a Chinese twin-engine stealth fighter developed for the People’s Liberation Army Air Force. It is China’s first operational low-observable combat aircraft and is commonly known as the Mighty Dragon.[1]
Development
The J-20 emerged from a Chinese programme for an advanced fighter and was publicly revealed shortly before its first flight in January 2011. It entered PLAAF service in 2017 and has since moved into large-scale production.
Development has continued through revised airframes, domestic WS-10C engines and the newer WS-15. A two-seat J-20S has also flown, an unusual configuration for a stealth fighter that may support command, training or teaming with uncrewed aircraft.[1]
Design
The J-20 has a long blended fuselage, delta-like wing, canards and canted twin tails. Main weapons are carried in an internal ventral bay, with smaller side bays for short-range missiles, helping reduce radar signature.
The aircraft is understood to combine an active electronically scanned array radar with electro-optical sensors, electronic warfare equipment and data links. Its large airframe provides substantial fuel volume and supports long-range operations over the western Pacific.[2]
Operational history
J-20 units serve in several PLAAF theatre commands and have participated in major exercises, patrols and intercepts. The fleet’s growth has made the aircraft a central element of China’s modern air-combat force.
The J-20 has not been exported. Public assessments of its exact radar signature, engine performance and weapons integration remain estimates because detailed official information is limited.
Variants and operators
The aircraft family includes J-20; J-20A; two-seat J-20S. Equipment, weapons and mission systems differ among production blocks and national fleets.
Principal or notable users include People’s Liberation Army Air Force. Some operators have retired early versions while others continue upgrades or new procurement.[1]
Specifications
Published performance figures depend on configuration, fuel, altitude and mission profile. Representative figures for the family include a maximum speed of Approximately Mach 2 and a range of Approximately 5,500 km ferry range with external tanks. The usual crew is 1; 2 in J-20S, and power is provided by 2 × Shenyang WS-10C or newer WS-15 afterburning turbofans.[1]
