I-class and Tribal armament compared with Italian destroyers

British I-class and Tribal destroyers illustrate different armament choices, including more torpedoes, more guns, and more flexible mount layouts.

Notes

British I-class destroyers carried four 4.7-inch guns in separate mounts and ten torpedoes in two quintuple launchers. Their four mounts gave more flexible firing arcs and limited how many guns a hit on one mount could disable. Tribal-class destroyers instead carried eight 4.7-inch guns and four torpedoes. In the comparison given here, the I class was lighter than the Italian ships, while the Tribal class was somewhat heavier. Both British types are cited as 36-knot ships, undermining the assumption that Italy's lighter armament necessarily bought superior speed. The comparison separates the number of guns from the usefulness and survivability of their mounting arrangement.
