Hi,I think it should just be expected that within days of a JF17 being delivered to Argentina the CIA will have someone looking at it...as is the same by China with anything sent to Taiwan.
The agency does not need to---.
The US has specialists who deal in this kind of thing just by looking at the visual of the aircraft or any machine---the industrial base of the country producing it---the capability and educational level of those producing it.
With all this information in front of them---they can asses pretty much up to the dot the capabilities of the machine in question.
But on hand visuals are an addition---.
