The Intermediate-Range Nuclear Forces (INF) Treaty between the United States and the Soviet Union ushered in the end of the cold war. The US withdrew its Pershing II missiles and the Soviet Union withdrew its SS-20s. Both countries were unwilling to use nuclear weapons, understanding the consequences of doing so—the Pershing II was a hundred times more powerful than the Hiroshima bomb. As a part of the treaty, both countries agreed that some of the missiles would be put in museums so that the public could see them and understand their history. A Pershing II and SS-20 are on display at the center of the National Air and Space Museum in Washington, DC.
As a public health precaution, the Steven F. Udvar-Hazy Center and the Museum in DC are temporarily closed. See our COVID-19 message.
