Luftwaffe

The Luftwaffe was the name for the German air force during World War II. Hermann Goering was the leader of the Luftwaffe. (PROSE: Timewyrm: Exodus) The Luftwaffe main fighter jets were the Messerschmitts, Junkers 88s, Stukas and Dorniers. (PROSE: /Carpenter/Butterfly/Baronet)

In 1937, during the Spanish Civil War, the Luftwaffe bombed Guernica and Durango using incendiary bombs. (PROSE: History 101)

During the Second World War, the Luftwaffe fought against the British Royal Air Force (RAF) in what became known as the Battle of Britain, a battle for air dominance over the English Channel, principally during 1940. (AUDIO: Their Finest Hour, PROSE: /Carpenter/Butterfly/Baronet) The British had refused to make peace with Germany after the latter had occupied France earlier in the year (AUDIO: Human Conflict) leading to Germany's dictator Adolf Hitler ordering the Luftwaffe to attack the RAF's airfields, radar sites and the RAF themselves, (PROSE: Timewyrm: Exodus) with the intention being to cripple the British's efforts to repel a German attack by air and make Operation Sealion a reality. However, despite many casualties, (AUDIO: Their Finest Hour) the British repelled the Luftwaffe's attack. (PROSE: /Carpenter/Butterfly/Baronet)

The Luftwaffe unable to win air dominance, the Nazis changed tactics. Instead of fighting the RAF directly, in 1941, the Luftwaffe bombed the United Kingdom's cities in an event known as the Blitz to destroy Britain's civilian morale, which was intended to incite them to surrender out of fear. (TV: The Empty Child) That too eventually failed. (TV: The Doctor Dances, PROSE: Exodus)

A Dalek, under the guise of a British Army Ironside, destroyed a squad of Luftwaffe Stuka planes as they approached London. (TV: Victory of the Daleks)

Alternate timeline
In an alternate timeline in which Nazi Germany won World War II and eventually conquered Africa as a result of the Seventh Doctor and Ace accidentally leaving laser technology in Colditz Castle in October 1944, the Luftwaffe was sent in to quell the Mau Mau Uprising against Nazi rule in Kenya. They proceeded to carpet-bomb the tribal areas and wipe out most of the native population. (AUDIO: A Thousand Tiny Wings)

Behind the scenes
In the real world, the Luftwaffe were part of the Wehrmacht. This, however, has not yet been explicitly stated within the DWU.
