The L class as Britain's Fletcher counterpart

What was the Royal Navy equivalent of the Fletcher class?

The L class, when compared by the capability and role the Royal Navy expected rather than by numbers built.

The L class is the Royal Navy's nearest Fletcher equivalent. The comparison concerns what each navy expected from a capable fleet destroyer. American production scale remains much larger than the British programme. Role and capability make the L-class analogy more useful than a simple hull-count comparison.
