What a modern Oliver Hazard Perry might look like

Would a modern Oliver Hazard Perry-class frigate need to be longer, broader, or simply copied?

It would probably grow in both dimensions to accommodate vertical-launch systems and modern equipment while preserving the original idea of an affordable numbers frigate.

A modern Perry would probably need a longer and broader hull to accommodate vertical-launch systems and other necessary changes. The original class was intended to provide large numbers of escorts at relatively low cost. Its survivability therefore should be assessed against that requirement rather than the standard of larger destroyer-level anti-submarine escorts. Differences in mission and intended capability explain why a more expensive ship can outperform it in particular areas. A modern version is considered possible, provided its design remains tied to the purpose of an affordable numbers frigate.
