Update the Fletcher class.
The Allen M. Sumner class tin cans would be a better platform to update. Six 5 inch guns in three mounts, greater fuel storage capacity on a longer hull. Engineering wise, a light off fuel oil pump and light off blower in bravo one and three would be ideal. Replace the solo shell evaps with triple effect flash evaps. Automated feed water controls and an automatic burner management systems would make sense also.
