If you throw enough money and energy into stuff, things will get done much faster.
Just like in the beginning of the pandemic with makeshift hospitals and ventilators. They suddenly were able to come up with tons of ventilators. Promising enough money to something kind of makes things happen much faster.
Just like the vaccine. It got expedited. Enough dedicated time and money makes things happen fast.
Got an analogy for you. THE BORDER WALL. Despite many millions? Billions? I really have no idea and Trump really wanted to get it done as his legacy. He was only able to get it partially done, and it's pretty unimpressive looking. Not close to what he touted.
If there was a real legit threat , an emergency, for the fun of it. Lets say it was zombies coming up from Mexico , they will be here in two months. The country would throw enough time and money to have the complete wall built in a month. However much money and manpower it would take, it would be done.
