A nuclear-powered battleship with an Ageis system and phalanx of cruise missiles ...
plus 16-inch guns ...
with effective air-missile defense would be a great weapons system ...

Battleships are a weapons platform that could always be updated and should never have been mothballed. Even if they are just “for show” that is worth it for gunboat diplomacy reasons. It’s a big stick and gets attention.
I agree. Amazing how many of these “obsolete” systems turn out to have great value against 16th century opponents like ISIS and al-Qaeda. Think of the A-10, still a great airplane.

The Russians tried that with the Kirov and her sisters. They soon discovered that without air cover the ships were large, slow targets.
Battleships are archaic. Heck aircraft carriers are close to being archaic what with nuclear torpedoes. They still serve a purpose for most police actions.
If you’re close enough to engage opposing forces with 16 inch guns, the battle has gone against you in this era.
