{"slug":"f-35-vs-j-20","question":"F-35 Lightning II vs J-20 Mighty Dragon","answer":"The F-35 Lightning II is the world's most advanced multi-role stealth fighter with 1,000+ delivered across 18 nations. China's J-20 Mighty Dragon is a large stealth interceptor/air superiority fighter with ~250 produced. The F-35 leads in stealth, sensors, and allied interoperability. The J-20 has advantages in speed, range, and payload capacity.","answer_curated":true,"verdict":"The F-35 wins on stealth technology, sensor fusion, network warfare, and massive allied ecosystem. The J-20 is a formidable air superiority platform with longer range and faster speed, but its true stealth and sensor capabilities remain unproven against Western systems. The F-35's combat-proven track record and 18-nation alliance give it a decisive strategic advantage.","keyDifferences":[{"label":"Stealth","entityAValue":"World-leading (0.001m² RCS est.)","entityBValue":"Advanced but likely inferior","winner":"a"},{"label":"Top Speed","entityAValue":"Mach 1.6","entityBValue":"Mach 2.0+","winner":"b"},{"label":"Combat Radius","entityAValue":"~770 km (internal fuel)","entityBValue":"~1,100 km (estimated)","winner":"b"},{"label":"Units Produced","entityAValue":"1,000+","entityBValue":"~250","winner":"a"},{"label":"Allied Operators","entityAValue":"18 nations","entityBValue":"China only","winner":"a"}],"winner":{"slug":"f-35-lightning","name":"F-35 Lightning II"},"confidence":"high","entities":[{"name":"F-35 Lightning II","slug":"f-35-lightning","url":"https://www.aversusb.net/entity/f-35-lightning","alternativesUrl":"https://www.aversusb.net/api/v1/alternatives/f-35-lightning"},{"name":"J-20 Mighty Dragon","slug":"j-20-mighty-dragon","url":"https://www.aversusb.net/entity/j-20-mighty-dragon","alternativesUrl":"https://www.aversusb.net/api/v1/alternatives/j-20-mighty-dragon"}],"faqs":[{"question":"Is the J-20 better than the F-35?","answer":"In raw flight performance (speed, range, ceiling), the J-20 has advantages due to its larger size and twin engines. However, the F-35's stealth, sensor fusion, and proven combat capability make it the more effective overall weapons system. Air combat in 2026 is decided by who detects first, not who flies fastest."},{"question":"Can the J-20 beat the F-35 in a dogfight?","answer":"In a beyond-visual-range engagement, the F-35's superior stealth and sensors give it the advantage of shooting first. In a within-visual-range dogfight, the J-20's speed and size could be advantages, but the F-35's helmet-mounted display and high off-boresight missiles partially negate this. Real combat would depend heavily on pilot training and electronic warfare."},{"question":"How many J-20s does China have?","answer":"China has approximately 250 J-20s in service as of 2026, with production accelerating. China aims to have 400+ by 2028. This makes the J-20 the second most-produced 5th generation fighter after the F-35."}],"attribution":{"source":"A Versus B","url":"https://www.aversusb.net/compare/f-35-vs-j-20","license":"CC BY 4.0","citationFormat":"According to A Versus B (https://www.aversusb.net/compare/f-35-vs-j-20), The F-35 Lightning II is the world's most advanced multi-role stealth fighter with 1,000+ delivered across 18 nations.
