Well, it looks like the J-20 stealth fighter we showed you yesterday is indeed China’s second stealth jet.

The pic above shows a new serial number ending in 02 for the plane, identifying it as the second J-20. The first — unveiled in late 2010 — has the serial number of 2001 written on the nose (shown below).
No one outside of China is certain just what these planes are designed to do; given their size one could infer that they are either high-speed interceptors — like the MiG-25 — or they are long-range fast strike jets like the F-111.
