Now that Trump is ramping up Wartime Measures in many other areas of industry, it might be worthwhile to look into some things that happened during WWII with RAPID development of technology.
First, read about Operations Research which later evolved into Systems Design and Systems Engineering.

And then have a look at this account by an American engineer who was stationed in the UK to support the development of Radar. While he was there, John G. Trump came over to be director of the BBRL which was the American lab a few doors down from the UK's lab in Malvern.

Note his comments about the Dutch. If you know of the Soviet bug in the Moscow Embassy, with no power source inside it, and no electronics, then you may have heard of Dutch radio/radar expertise used by the CIA

The image is the actual listening device that the Soviets used to transmit audio from an office in the Moscow American Embassy to a listening post outside.
And here is a bit more about the Dutch Radar Laboratory and their museum

I believe similar passive technology is used in the Mexican border wall to alerts CBP of the exact location of any attempts to go over or under the wall. Read the articles and then look at wall construction photos. Absolutely BRILLIANT and an example of more or less suppressed technology since WWII.
==But what if this stuff is in use and further developed inside the military. Some of the wonders that people have glimpsed are likely true, and they are American military devices and craft.
