Were half-battleship, half-carrier designs sound ideas?
Short answerOnly on paper under treaty constraints; operationally, carriers were better kept out of gun range and optimized for aviation.
NotesThe hybrid concept could make sense on paper while treaties forced navies to stretch limited tonnage and carrier roles remained unsettled. Heavy guns promised a degree of self-defense when a carrier's place in the fleet was still unclear. In practice, those guns pulled the ship toward an engagement it should avoid. A fleet benefited more from a unified carrier type operating outside enemy gun range.
