China J-20 Stealth Fighter With 4 External Fuel Tanks Flight Testing

Are they aiming at this being a long range missile truck?  We're all thinking an F-22 competitor but this is shaping up (at least to my eye) to be something completely different.

I wonder if this is aimed more at killing ships...or as some have speculated AWACS/Tankers...but not at fighting F-22's.
