The Luftwaffe (Wehrmacht air arm) was founded in 1935 in contravention of the Treaty of Versailles which forbade Germany for amassing arms. Despite this, sanctions were not applied and within just a few years Germany had arguably the most organised and advanced air force in the world.
The projects shown here are all real designs from a variety of manufacturers submitted to the RLM (Reichsluftfahrtministerium) during World War 2. Many speculative designs, some of which deployed very advanced engineering were made during the war, especially towards the end. However, crippling lack of resources and experienced pilots, together with poor authorities direction and the advance of the allies, meant that very few designs even made it to mock-up or wind tunnel testing let alone into production.
The advanced technology became a very valuable commodity after the war: aeronautical engineers and scientists had valuable information which was quickly utilised by all sides for what was to known as the Cold War.
Not all the designs would have been successful, but it is arguable that the allies may have taken several years to independently develop the knowledge at the disposal of the Luftwaffe.
