I was on a carrier in ‘61-62. We had A-3 Sky Warrior aircraft that carried nukes on every flight. Always arrived on the flight deck with about 4 armed Marine guards, who remained with the nukes until installed in the aircraft.
Our modern carriers have nuke carrying aircraft, as well, and our subs have nukes. I believe all of the silos in the US were shut down.
Nothing wrong with letting “Liddle” Kim know what else we might do.
To the best of my knowledge, Minot and FE Warren still have active silos.
