Poland's Grom class filled the same heavy-destroyer niche as the Tribals

Were the Polish Grom-class destroyers better Royal Navy destroyers than Britain's own contemporaries?

They closely matched the Tribal heavy-destroyer role and were especially valuable because Britain had too few ships in that category.

The Polish ships fit one part of Royal Navy destroyer policy rather than standing as categorically superior designs. The Grom class occupied much the same heavily armed destroyer niche as the Tribals. Its practical value lay in filling a shortage after the first British Tribals proved useful but before Canadian and Australian Tribals and the Battle class arrived in strength. Only one Battle-class destroyer reached the Pacific before the war ended, which makes the timing of the Polish reinforcement especially important. The comparison shows that a ship's value can depend as much on when it joins a fleet as on whether its paper characteristics exceed a contemporary design.
