See my post #16Yup, they were fast. What else can they do? How's the range on 'em? What else they got, DD-wise?
They were designed with an eye on tackling the Italian Fleet in the Western Med basin. With France having bases on the southern Metropolitan French coast at Toulon and at Oran in Algeria and Bizerte in Tunisia, range was less of an issue than for the USN looking to the extended distances of the Pacific. Sea conditions are generally less rough in the Med than the North Sea or Atlantic.
Their role was more akin to a light cruiser than a destroyer in those pre-radar days.
As always. Horses for courses. You build what you believe your navy needs to fight the war it expects.
