Shenyang J-11 Front Orthographic View
The Shenyang J-11 (NATO reporting name: Flanker-B+/L) is a Chinese twin-engine, multirole fighter aircraft manufactured by the Shenyang Aircraft Corporation (SAC). It is a license-produced and extensively upgraded derivative of the Soviet-designed Sukhoi Su-27SK air superiority fighter, forming a cornerstone of the People's Liberation Army Air Force (PLAAF).
Here are its key specifications, noting that there are significant variations between the initial J-11 and later, indigenously upgraded J-11B/BG/D variants:
General Characteristics (primarily J-11B variant):

Wingspan: 14.7 m (48 ft 3 in)
Height: 5.92 m (19 ft 5 in)
Wing Area: 62.0 m² (667 sq ft)
Empty Weight: Approximately 16,380 kg (36,112 lb)
Gross Weight: 23,926 kg (52,748 lb)
Max Takeoff Weight (MTOW): 33,000 kg (72,753 lb) (J-11B); reportedly up to 32,000 kg (70,548 lb) for J-11BG
Fuel Capacity: 9,400 kg (20,723 lb) internal
Powerplant:
Early J-11/J-11A: 2 × Lyulka (now Saturn) AL-31F afterburning turbofan engines (approx. 123 kN / 27,500 lbf with afterburner each)
Later J-11B and variants: 2 × Shenyang WS-10A "Taihang" afterburning turbofan engines (approx. 132 kN / 29,700 lbf with afterburner each); WS-10B with 13.2 tons thrust for J-11BG
Performance:
Maximum Speed: Mach 2.35 (approximately 2,500 km/h or 1,553 mph) at altitude
Range: 3,530 km (2,190 mi, 1,910 nmi)
Combat Range: Approximately 1,500 km (930 mi, 810 nmi)
Service Ceiling: 19,000 m (62,000 ft)
Rate of Climb: 300 m/s (59,000 ft/min)
G-Limits: +9g
Armament:
Gun: 1 × 30mm Gryazev-Shipunov GSh-30-1 cannon with 150 rounds
Hardpoints: 10 (J-11B, J-11BS) to 12 (J-11D, J-11BG) external hardpoints with a maximum capacity of 6,500 kg (14,330 lb) for J-11B; up to 8,000 kg (17,637 lb) for J-11BG.
Missiles (J-11B/BG/D can carry a wider range of indigenous missiles):
Air-to-Air: PL-8 (short-range IR), PL-9 (short-range IR), PL-10 (short-range IR, later variants), PL-12 (medium-range active radar homing, akin to AIM-120 AMRAAM), PL-15 (long-range active radar homing, later variants for J-11BG/D), also capable of R-27 and R-73 (from earlier Russian-sourced J-11s).
Air-to-Surface/Anti-Ship: Kh-29TE, Kh-31 (anti-radiation/anti-ship), YJ-83K anti-ship cruise missile (J-11B/BH/BSH), various precision-guided munitions (laser-guided bombs, GB-series guided bombs, LS-6 glide bombs).
Rockets: Unguided rocket pods (S-8, S-13, S-25 series).
Bombs: Various free-fall bombs (e.g., 250kg, 500kg), cluster bombs.
Avionics and Systems (varies significantly by variant):
Radar:
Initial J-11/J-11A: Russian NIIP N001VE pulse-Doppler radar.
J-11B: Indigenous Chinese Type 1493 multi-mode pulse-Doppler radar (reportedly more capable than N001VE).
J-11BG/J-11D: Advanced Active Electronically Scanned Array (AESA) radar (e.g., JKL-24).
Electro-Optical System: OEPS-27 IRST (Infrared Search and Track).
Cockpit:
Early J-11: Analog cockpit similar to Su-27.
J-11B onwards: Glass cockpit with multi-function displays (MFDs), Head-Up Display (HUD), Helmet-Mounted Sight (HMS).
Electronic Warfare (EW): Integrated electronic warfare system, radar warning receiver (RWR), chaff and flare dispensers, potentially Gardeniya ECM pods.
Other: Digital fly-by-wire flight control system (on later variants), Onboard Oxygen Generation System (OBOGS) on J-11B, improved data links.
Variants:
J-11 (or J-11A): Initial license-produced Su-27SK, assembled from Russian kits, with minor Chinese modifications.
J-11B: First indigenously produced version with significant Chinese content, including WS-10A engines, domestic avionics (Type 1493 radar), and capability for Chinese weaponry (PL-8, PL-12).
J-11BS: Twin-seat trainer/combat variant of the J-11B.
J-11BH/BSH: Naval versions of the J-11B/BS for the People's Liberation Army Naval Air Force (PLANAF), but not carrier-capable like the J-15.
J-11BG/BGH: Upgraded J-11B/BH with AESA radar, enhanced avionics (similar to J-16), and capability for PL-10 and PL-15 missiles, significantly improving multirole capabilities.
J-11D: Advanced variant with AESA radar, increased use of composite materials for reduced radar observability, improved IRST, and further enhanced weapon capabilities (e.g., PL-15). This variant was reportedly not mass-produced in favor of the J-16.
The J-11 series represents China's progressive mastery of advanced fighter technology, evolving from a licensed copy to a highly capable, indigenously developed fighter with multirole capabilities.
