According to the Chinese aviation expert Dafeng Cao who posts under the Twitter handle @xinfengcao, six J-20 stealth fighters will be inducted into the Chinese air force at a formal ceremony later this month.
Recent speculations refer to the J-20 as an air-to-air fighter with an emphasis on forward stealth, high-speed aerodynamics, range, and adequate agility. The J-20 could threaten vulnerable tankers and ISR/C2 platforms, depriving Washington of radar coverage and strike range. However one of these targets, the Northrop Grumman E-2 Hawkeye, is reported to be optimized for spotting fighter sized stealth aircraft such as the J-20
