History Chengdu Aerospace Corporation (CAC
Chengdu J-20 (Chinese: 歼-20; pinyin: Jiān-Èrlíng), also known as Mighty Dragon "Fagin"
The Chengdu J-20 (Chinese: 歼-20; pinyin: Jiān-Èrlíng), also known as Mighty Dragon (Chinese: 威龙; pinyin: Wēilóng, NATO reporting name: Fagin), is a twinjet all-weather stealth fifth-generation fighter aircraft developed by China's Chengdu Aerospace Corporation for the People's Liberation Army Air Force (PLAAF). The J-20 is designed as an air superiority fighter with precision strike capability. The aircraft has three variants: the initial production model J-20A, the thrust-vectoring J-20B, and twin-seat aircraft teaming capable J-20S.
Descending from the J-XX program of the 1990s, the aircraft made its maiden flight on 11 January 2011, and was officially revealed at the 2016 China International Aviation & Aerospace Exhibition. The aircraft entered service in March 2017 with the first J-20 combat unit formed in February 2018, making China the second country in the world and the first in Asia to field an operational stealth aircraft

Design
Chengdu J-20 showcasing maneuverability at Airshow China 2018. Characteristics
The J-20 has a long and blended fuselage, with a chiseled nose section and a frameless canopy. Immediately behind the cockpit are low-observable diverterless supersonic inlet (DSI) intakes. All-moving canard surfaces with pronounced dihedral are placed behind the intakes, followed by leading edge extensions (LERX) merging into the delta wing with forward-swept trailing edges. The aft section has twin outward canted all-moving fins, short but deep ventral strakes, and conventional or low-observable engine exhausts.[64][65]
One important design criterion for the J-20 is high instability. This requires sustained pitch authority at a high angle of attack, in which a conventional tail-plane would lose effectiveness due to stalling. On the other hand, a canard can deflect opposite to the angle of attack, avoiding stall and thereby maintaining control. A canard design is also known to provide good supersonic performance, excellent supersonic and transonic turn performance, and improved short-field landing performance compared to the conventional delta-wing design.
Leading edge extensions and body lift are incorporated to enhance performance in a canard layout. This combination is said by the designer to generate 1.2 times the lift of an ordinary canard delta, and 1.8 times more lift than an equivalent-sized pure delta configuration. The designer claims such a combination allows the use of a smaller wing, reducing supersonic drag without compromising transonic lift-to-drag characteristics that are crucial to the aircraft's turn performance.

Analysts noted that the J-20's airframe employs a holistic approach to reduce its Radar cross-section (RCS), uniquely combining canard wings with leading edge root extensions (LERX). The chined forebody, modified radar radome, and electroconductive canopy use a stealth shaping, yielding signature performance in a mature design similar to the F-22.
