>>639048903rd world countries don't have (big) black projects, instead of developing secretly, they show everything and ever more.
Like vast China with giant empty regions flies their newest prototypes like J-36 in the middle of a city during daylight.
Or like Iran that shows even projects that are not real like Qaher-313, imagine if they actually developed something.
Or like russia that boasts about PAK-DA and Su-75 and then quietly cancels them years later
