AVIATION WEEK: China's J-20 Stealth Fighter.

The J-20’s primary mission ... may be to use stealth and speed to break through the [defensive combat air patrol] CAP and threaten vital tankers and ISR platforms. Its range gives it a “long lance” advantage—if the tankers, ISR aircraft and escorts have to stay out of the J-20’s range, the tactical aircraft that they support will not have the airborne radar cover or range needed to reach their targets.

Also, an anti-radar missile would give the J-20 some capability against shipping, even with internal weapons. .

In a very broad sense, the J-20 could turn out to be an analogue to the Soviet-era Tu-22M2/3 Backfire bomber—an efficient and practical blend of low-risk technologies that generates options for its users and difficult problems for its adversaries.

A long article, but interesting.
