How to identify Royal Navy destroyers by silhouette

Funnels, superstructure, and gun arrangement provide a practical sequence for narrowing down similar British destroyer classes.

Question

What is the best way to tell Royal Navy destroyer classes apart by silhouette?

Short answer

Count funnels first, compare the superstructure next, and then use the number and shape of the gun mounts to narrow the class.

Notes

Start with the number of funnels and the outline of the superstructure. The gun layout then narrows the possibilities, especially when a class carries a distinctive number or arrangement of mounts. Profile photographs and silhouette books help train the eye, but closely related Royal Navy designs can still be difficult to separate. L- and M-class destroyers illustrate the problem because their major features are extremely similar. This sequence offers a repeatable method for reading wartime photographs instead of relying on one striking feature.
