Why is the underside so dirty?
Well, airplanes get dirty, especially bellys and undersides?? If its been to the boat, sea water is salty and especially littoral waters may be muddy and heavy with particulates, in any regard salt is "baaadd". Lots of airplanes leak fluids, and ailerons, flaps, stabilators, ruddervators, etc require hinges to be lubed liberally, in addition there is fuel, fluids, and just accumulated crud that gravity and airflows tend to concentrate on the belly, add gpu's and you have a perfect storm.Why is the underside so dirty?

I am quite surprised that China allows some photos of J-15 factory production for public.
It shows at least 6 (possibly 9) in various stages
There might be a lot of top-notch technology in the J-15 production of parts, perhaps in Ti printing heavily loaded parts, but you won't see anything of that in these photographs.Why not? The J-15 isn't exactly top-notch technology out there.

Those photographs have presumably seen by knowledgeble people to make sure nothing significant is visible.You are right, at least to me ... its nothing. But trained and professional staff could tell a lot just from the photographs
