trump said Hydrosonic again.Still trying to decode.
Thank you.
Can't find anything on hydrosonic missiles yet but I agree it is probably a message to those who know what he means by it.
"These undersea missiles achieve their speed essentially by encasing the torpedo inside a bubble to eliminate the water's hydrodynamic drag. Once inside this bubble, and free of the water's drag, a rocket engine shoots the munition through the water faster than a NASCAR racer."
