What technical rationale justified the US Navy's cage masts?
Short answerThe rationale was weak, especially because the structure placed considerable weight high in the ship.

The structures placed substantial weight high in the ship and invite comparison with Japanese pagoda masts. Their distinctive appearance came with consequences for stability and topweight. Superstructure arrangements were engineering decisions as well as visual signatures.
