USS Antietam (CG 54) is not a Coast Guard boat.
Should be USS Antietam (DDG 54)
Chances are that the hull would not stand up to sea duty any longer nor are there any powder or shells for the guns. Nice idea 50 years too late.
Could be wrong but I think CG stands for “Cruiser Guided [Missle]”
I worked with the U.S.S Antietam and she is a Cruiser-Cruiser Guided-(Missile Class).
The New Jersey...she’ll be fine, and recommend pulling off two of the main batteries anyway and wedging in VLS systems.
Give ATK the contract for brand new replacement 16” shells and propellant.
Pull out all the old wiring and give her current “avionics” and fire control. CIWS all over and nice new auto-cannons to replace the dual five inch mounts.
For somebody sitting (literally) in a Lazy Boy I sure do have a vivid imagination.
