Operational Context
Shenyang J-11 — twin-engine air superiority fighter
The J-11 first flew in the late 1990s and entered service in 1998. Initially produced under license from Russia, later versions were built with increasing levels of indigenous technology. The aircraft features a large blended wing-body layout with twin vertical stabilizers and a focus on maneuverability.
Powered by two turbofan engines producing approximately 27,000 pounds of thrust (120 kN) each with afterburner depending on variant, the J-11 can exceed Mach 2. Maximum takeoff weight exceeds 70,000 pounds (31,750 kg). The aircraft carries air-to-air missiles and other external stores.
The J-11 has served as a backbone of China’s air superiority capability. Ongoing upgrades have enhanced radar and weapons integration. The type remains in active service with the People’s Liberation Army Air Force.
