Why German destroyers adopted 150 mm guns

Germany's 150 mm destroyer guns reflected a pursuit of headline power and carried a serious rate-of-fire penalty.

Question

Were the 150 mm guns on German Second World War destroyers a response to British destroyer tactics in the First World War?

Short answer

The choice is attributed mainly to a desire for maximum apparent power. The larger guns aggravated the destroyers' rate-of-fire problem.

Notes

The large gun is presented as a pursuit of maximum apparent power rather than a direct answer to Royal Navy destroyer performance in the First World War. Germany chose the most powerful weapon it could field without giving enough weight to the operational consequences. The 150 mm weapon aggravated the destroyers' existing rate-of-fire problem. Shell size alone therefore gives a misleading picture of destroyer combat effectiveness.
