How many aircraft did the X Fliegerkorps assemble for Norway?

The invasion of Denmark and Norway, Operation Weserübung, began on 9 April 1940 and required complete coordination between the three branches of the Wehrmacht. The air component was commanded by Lieutenant General Hans Geisler, heading the X Fliegerkorps (10th Air Corps). According to the Illustrated Encyclopedia of Aviation, his forces totalled around 1,000 aircraft, split evenly between the Junkers Ju 52/3m transports of the Transportchef Land and the combat aircraft.

The great danger of the operation was not the weak Norwegian forces, but the Royal Navy. That is why the X Fliegerkorps' main strike force was made up of anti-ship bombers, while ground support played a very secondary role. The basic weapon was not the Stuka or the Zerstörer, but the medium bombers. Single-engine fighter cover was reduced to 30 Messerschmitt Bf 109E-1s of II/JG 77, together with around 70 Bf 110C-1 heavy fighters; 70 aircraft were assigned to reconnaissance and 30 He 115A-1 seaplanes to coastal reconnaissance.

The transport half of that force was decisive. Around 500 Ju 52/3m took part in what the encyclopedia calls the largest airborne operation planned to date; according to the English Wikipedia, in the Norwegian campaign the Ju 52s flew 3,018 sorties and carried 29,280 people. More units were sent at the end of April: on 24 April 1940 the X Fliegerkorps was incorporated into Luftflotte V, and its forces then comprised 710 aircraft, with the bomber force increased to 360. With most of Norway in German hands, its primary mission became supplying and reinforcing the ground troops.
