Twenty-one months after China’s Chengdu aerospace firm unveiled its J-20 jet fighter prototype — Beijing’s first stealth warplane — the rival Shenyang company has revealed what appears to be a competing, radar-evading plane. Over the weekend photos of increasing resolution leaked online depicting a previously unknown, black-painted warplane with the distinctive qualities of a stealth design. So China now possesses two potentially combat-capable stealth jets. But — and we can’t emphasize this enough — it’s not at all certain that either will make it through development , testing and full-scale production and into front-line service. Just ask the U.S. Air Force, which since the 1980s has overseen creation of no fewer than four different stealth fighter prototypes but so far has only managed to equip just six war-ready squadrons with fewer than 200 operational jets. And that at an extremely high price: up to $700 million per plane, depending on how you count . The J-21 that appeared this weekend is outwardly similar to the nearly two-year-old J-20. Both have two engines, two tails, big trapezoidal wings and the sharp, faceted features of a radar-evading plane. In that sense the J-21 and the J-20 evoke America’s first batch of stealth prototypes, the twin-tail, twin-engine Lockheed YF-22 and Northrop YF-23. Those two planes flew head-to-head in 1991, vying for an Air Forc
