 Pagoda masts were built on existing tripod masts by adding searchlight and other platforms, lookouts and shelters upon each other, the end result resembling a pagoda temple.The superstructures were constructed on the majority of the ships that were rebuilt by the Japanese, including the s and the , , and -class battleships.The additional platforms were supported on the ships' original tripod foremasts (a design also extensively used by the Royal Navy) and these were suitably strengthened to bear the extra weight they had to carry.
