Could Germany answer a more powerful Queen Elizabeth with Zeppelins carrying armour-piercing bombs or torpedoes?
Short answerDropping battleship shells was conceivable, but accurate aiming would be very difficult. The torpedo suggestion receives no developed answer.
NotesA hypothetical German response to larger British battleships is to build more Zeppelins and arm them for attacks on ships. Dropping battleship shells is treated as technically conceivable, with a brief comparison to Japanese use of such weapons. The difficult part would be aiming and dropping them accurately onto a moving target. The suggestion remains a counterfactual possibility without an established effective attack method.
