What are the objections to carrier submarines?
Short answerThe launch and recovery cycle is the central objection; an SSGN can conduct a missile strike without waiting on the surface for aircraft.
NotesA carrier submarine combines requirements that pull in opposite directions. It must carry a useful air group and spend time on the surface launching and recovering it. An SSGN avoids that problem by firing missiles without waiting on the surface for an air group to return. Proposals using disposable aircraft do not solve the recovery problem for a conventional carrier submarine.
