Type 83 and the modern cruiser under another name

How large and capable might future British cruisers or Type 83 ships be, and why are modern cruiser-sized warships called frigates or destroyers?

The discussion expects a large general-purpose Type 83 rather than a frigate derivative and argues that modern labels increasingly describe primary roles, not displacement.

Type 26, the Canadian River class, and the prospective Type 83 show that modern displacement no longer maps neatly onto historic labels. A ship comparable in size to a 1930s cruiser may be called a frigate for anti-submarine work or a destroyer for air defense. Procurement politics also matters: role-based names are easier to justify than the historically and politically loaded word cruiser.
