We still have two of the Iowa class battleships, modernized in the 1980's with Tomohawk cruise missiles, Harpoon missiles, CIWS and retaining their 16" guns in the reserve fleet.

We could activate those in a dire crisis.

That is so cool, this ship.
Take a look at the blast wave as the massive guns are shot off.
I bet those guns have a nasty recoil, even on a huge ship like that.
