The navy has many duplicate ship types, i would love to see Trump smash the tradition, and build a more unique fleet…
First take a commercial super oil tanker, make it end to end cruise missile launchers, imagine a ship capable of launching 500 to 1,200 cruise missiles roll up to a conflict zone. It would over whelm any anti air defense network. A nice bonus, if the enemy had a choice between a carrier kill or a oil tanker of mass destruction… They would kill the bigger threat and destroy the tanker, saving thousands of sailors. This ship would seldom move and have a massive escort, but could wipe out pretty much any cities and defenses it wants to. Uss Overkill?
A double hull super carrier, allowing for larger planes, particularly small bombers to be aboard. One side for launching fighters, the other side retrieving. Elevators in the middle of the ship, connecting the 2 hulls fighter bays.
Im of the belief battleships aren’t dead, that there miss used. Upgrade the primary weapon systems, let them bombard targets from 50 miles out at sea. With even deck gun advancements they should have a 60 mile range.
Obviously do more with battery powered submarines.
Obviously develop more anti aircraft and missile systems.
These are all achievable, wouldn’t need to develop much technology. And the ability it would bring to the fleet would be insane… Park the oil tanker of destruction off an enemies door step, lets say 800 cruise missiles aimed at them. Any sentient enemy will look at it with total terror. It single handedly can take out 4 out of 5 regimes of any country its pointed at?
