China inducting J20 stealth fighters into air force as active service planes

At least six J-20s stealth fighters are in active service, with four tail numbers 78271,78272,78273 and 78274 identified. And another six are ready to be delivered by end of Dec 2016

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
