The destroyer was the most capable and most feared escort vessel the allies possessed early in the war. It was larger and more heavily armed than the destroyer escort and considerably faster. They were also of shallow draught, making it difficult to torpedo them.
The most interesting variant of those were the flush-deckers (or "four-pipers") of WWI vintage that got pulled out of mothballs and 50 of them were sold very expensively to the Royal Navy in 1940. They were ill suited to hunt U-boats due to their age and lack of modern equipment, yet they served all over the North Atlantic.
All Destroyer classes (in service with the Polish Navy).
2 ship classes.
Please note that we list the classes by navies that initiated/owned the class. Often vessels of certain classes were then built for other nations (or lent), those ships are not visible here but only through the navies pages or by looking into each class.
