" At President Trump’s direction, the Department of Defense will establish and implement a plan to demonstrate the energy flexibility and cost effectiveness of a small modular reactor at a domestic military installation, and will pilot a transportable small modular reactor for a mission other than naval propulsion for the first time in half a century."

A few thoughts...

This would mean that we already have them, and he's going to showcase them "at a domestic military installation".

Trump has postured more than once to our foreign enemies that we have the best weapons, things that have never been seen before. He's about to show that he's not full of crap.

By showing that we have cutting edge weapons, he's telling foreign countries, DON'T GET INVOLVED when I or the military move to REmove the domestic traitors that Biden, Harris, Clinton, Obama, Schiff, etc. etc.
