How did the design philosophy of Fletcher and Gearing destroyers differ from Tribal and Battle-class destroyers?
Short answerThe American ships remained centered on fleet torpedo attack, whereas the British types prioritized guns for fighting and clearing enemy destroyers.
NotesAll four types descend from the torpedo-boat destroyer and combine guns with torpedoes, but they rank those weapons differently. The Fletcher and Gearing classes are fleet destroyers designed around delivering torpedo attacks against an enemy fleet. The Tribal and Battle classes emphasize guns so they can defeat opposing destroyers, clear the path, and protect other flotilla units. When gun and torpedo placement compete, the American designs favor the torpedo battery while the British gun-centered designs favor the artillery.
