Choosing a British escort for mass production

Which British escort-sized warship would be most useful to mass-produce before a war?

A gun-armed, Sea Wolf-equipped Type 22, particularly in the later Batch 3 form.

The later Type 22 frigate is the preferred British escort for mass production. A Batch 3-style configuration adds guns to the class's Sea Wolf missile defence. The resulting ship has enough breadth for wartime escort and general-purpose work. Mass production gains value when it repeats a mature, useful design instead of maximizing hull numbers alone.
