Does the ability of air power to sink ships prove that aircraft can replace navies?
Short answerNo. Aircraft are dangerous to ships, but a navy adapts through aviation, sensors, weapons, tactics, and dispersion instead of accepting a one-sided contest.
NotesAircraft can certainly sink warships under favorable conditions. The analytical mistake is to hold the fleet still while allowing aviation technology and doctrine to improve without opposition. Navies respond with organic aircraft, radar, anti-aircraft weapons, maneuver, dispersal, camouflage, and changes in operating practice. Simple declarations of one arm's supremacy are poor theory because warfare is an interactive contest of adaptation.
