How would additional cruiser or destroyer programs help the modern US Navy?
Short answerThey would restore graduated presence options so the Navy does not use an Arleigh Burke for nearly every mission below a carrier group.
NotesThe Arleigh Burke has become both the routine presence ship and the higher-level warning ship because the US Navy lacks enough frigates below it and a distinct major surface combatant above it. Constellation-class frigates may restore the lower rung, but only gradually. The problem is diplomatic as well as tactical because deterrence needs visible, graduated steps before a carrier strike group arrives.
