Why is a modern aircraft-carrier submarine a bad idea?
Short answerA hangar and its openings undermine pressure-hull design; VLS-launched reconnaissance and strike drones offer a more practical version of the concept.
NotesDeep-diving submarines depend on an uncompromised pressure hull, making large openings and aviation spaces an unattractive design trade. A more credible path is an SSGN-like boat that launches drones or drone-like missiles from vertical-launch tubes. Those vehicles could scout and attack without imposing a carrier flight deck and hangar on the submarine.
