I've always wondered-would an air assault carried out on a warship ever be possible? Would the helicopters be able to land on the ship in the first place, or would the ship be able to maneuver away from them and/or shoot them down? If the attacking forces somehow manage to land troops on the ship (via the element of surprise?), what amount of soldiers would be required to overtake a decently-sized vessel, like a modern frigate? What about a modern-day destroyer or cruiser? A modernized battleship like USS Iowa (Yes, I know it's retired, this is a theoretical scenario)? Maybe even an aircraft carrier? Is any of this plausible, or just plain ASB impossible?
