The Cold War Gallery in the National Museum of the United States Air Force features aircraft that span the years of the Cold War. According to the Museum:
The Cold War dominated the second half of the 20th century. This confrontation grew out of the clash between the ideologies of the Western democracies led by the United States -- and the communist nations led by the Union of Soviet Socialist Republics (USSR). The ever-present threat of nuclear weapons made this period the most dangerous one in world history, but the diligent efforts of the men and women of the U.S. Air Force helped bring this conflict to a peaceful end.
One of the displays shows models of some Soviet aircraft used during the Cold War. These use a 1/72 scale.
