Could a Second World War airship carrying a few fighters have helped defend convoys against U-boats?
Short answerIt might have helped, but limited capacity and weather exposure make an escort carrier the more effective solution.
NotesAn airship carrying two to four fighters could remain over a convoy and refuel aircraft used to search for U-boats. It could provide extra patrol coverage if the operating arrangement worked. The airship would carry too few aircraft for the effort involved and would remain highly sensitive to wind and other operating conditions. An escort carrier delivers the same general benefit with a larger air group and a more workable naval platform.
