Even back to the days of Archimedes and before, invention and innovation can be fueled by war and military research across many fields. Technology is almost directly tied to defense/intel research even this here internet. That is one of the dualities of the human condition. At least good can come from it.
Probably lots of reasons that research like this is attainable is due to massive budgets/funding and the ability to research an try many things in these types of r&d departments and the urgency of some research/development goals. Intelligence or military project conditions rarely apply to private market project budgets and timelines, only comparison is maybe academic research where some of the same goals/freedoms apply and both have reduced labor or essentially free labor.
