Carrier fighters first disrupt formations into smaller flights. Heavy anti-aircraft guns then force those groups to split further, while medium and close-range weapons distract, drive off, or destroy individual aircraft. This layered system aims to overload the attackers rather than expecting any single weapon to stop the strike. Because ships maneuver, disruption alone can spoil an attack even when no aircraft is shot down; the pilot's bomb or torpedo may simply miss the moving target.
