4. D-Day was the Biggest Naval, Land and Air Operation Ever
There has never been a larger naval, air and land coordinated invasion of the magnitude of D-Day’s. It was conducted in two main phases: the amphibious Normandy landings and an airborne assault. Well over 18,000 Allied paratroopers were parachuted into the drop zone along the coast shortly after 6 June midnight to support the infantry divisions that landed earlier on the beaches.
The Allied forces had apparent air supremacy over Germany and flew more than 14,000 forays in support of the coastal landings. Also, they had about 7,000 naval vessels which carried out Operation ‘Neptune’, Overlord’s naval component. They landed well over 132,000 ground troops at Normandy and took care of German coastal defenses before and during the landings.
