I have noticed that the exhausts are not ducted and I wonder whether it will cause an increase in radar return signature. The following is a diagram of the ADVENT engine peogram of the USAF, notice how the exhaust is ducted (as well as the inlet) to achieve a minimum amount of rear RCS. Can the J36 also adopt such a design while still using the WS15 interim engine without losing too much thrust?A bit more artwork of the J-36 fightercruiser

I hope you realized now those are artworks…I have noticed that the exhausts are not ducted and I wonder whether it will cause an increase in radar return signature.

Of course, clearly so.View attachment 143663
With the photo of the rear showing its YF23-ish nozzles it is almost without doubt the exhaust is not ducted.
You see the details inside the nozzle from like 4 black pixels?View attachment 143663

I don't believe this has been shared before.

The chief designer's paper certainly noted the S-bend nozzle and the three-stream flow of the adaptive engine. But, "For non-afterburning subsonic stealth aircraft such as the B-2, the S-bend nozzle has been used; however, the application of the S-bend nozzle in the afterburning engine still faces more complex design issues such as local high temperature areas, performance degradation caused by uneven flow, and fluid-structure coupling under complex combined loads."View attachment 143663
