In your picture, you claim the "tail fins and booms" are an inferior design. I disagree. The tiny ventral fins follow planform alignment with the large vertical stabilizers and add virtually nothing to RCS. To the contrary, the "tail fins and booms" dramatically increase the J-20 Mighty Dragon's side infrared-stealth.

J-20 Mighty Dragon ventral fin blends cleanly into the fuselage side-profile
J-20 Mighty Dragon ventral fin blends cleanly into the fuselage side-profile and there is no increase in surface area for radar reflection.
[Note: Thank you to HouShanghai for the picture.]

From my August 12, 2011 post:
J-20 ventral fins contribute to lateral radar and infrared stealth
The J-20 DSI intake is prominent from a rear port-side view of the stealth fighter.
I just noticed the J-20 ventral fins shield the jet engines' radar and infrared signatures from a lateral scan.

The RAM-coated ventral fins will either absorb or reflect the incoming radar wave. Looking at the picture, an incoming radar wave will be reflected into the sky. The hottest part of a plane is the jet engine. The jet exhaust is noticeably cooler. Hence, the ventral fins shield the jet engines from lateral view and contribute to lateral infrared stealth.

another B.S dont tell such absurd analysis man,Tell it to some illiterate villager they would beleive u,if u tell this to any aeroexpert they would slap u
you told it blends from side profile but what from behind & below ?It would be surely detected by anti stealth very low frequency radar most probably ground based radars (X band 8 to 12 GHz)from below and aesa radar from behind
so again a big LOL for u
