Though planned as a commercial airport, its importance to the military increased dramatically during the Third Reich. During World War II it was exclusively used for military purposes. An airlift between the airport and Breslau (modern day Wrocław) was established to support German troops during the Siege of Breslau in the spring of 1945. Attempts to destroy buildings and equipment before Allied troops could occupy Dresden failed due to the resistance of civil airport employees.
During the following years, the airport was used as an education centre for the Soviet army. It was reopened for commercial traffic on 16 June 1957. In 1959 international air traffic resumed, primarily to Eastern Bloc countries.
Between 1955 and 1961, the East German government decided to develop its own aviation industry centred on Dresden. Although this development ultimately failed, it increased the importance of Klotzsche Airport considerably, and still shapes the design and atmosphere of the airport today.
