J-20 5th Gen Fighter Thread VIII

[Blitzo]

so then why don't you explain why you think the J-20 isn't an interceptor instead of deleting posts that disagree with your view? You claim that this is a "settled" topic but I don't see it being "settled" anywhere outside this specific forum. In fact the general consensus over at SPF is that it is indeed an interceptor who's primary mission is to snipe tankers and awacs, while being able to engage other fighters if absolutely necessary

Congratulations on your permanent ban.

My only question was why have this big housing space for a sensor that is occupying not even ¼ of the space? Did something get removed for airshow displays?

I have seen this configuration in other images as well, but not sure if they were also from airshows.

The size of the transparent glass of the housing (the aperture itself) and the associated "empty space" is not so much for the size of the sensor but rather providing a sufficient FoV for the sensor given the angle the sensor is situated at within the canted angle of the side of the nose.

Wouldn't it make more sense to have a small protrusion instead like the luneberg lense? Why bury it in the airframe with a reduced FoV?

There are RCS penalties to protrusions even if you apply RAM/use facets. This also introduces drag to the airframe. Unless absolutely necessary you want to keep things sticking out to a minimum.
